It’s been a few months since I’ve been on a WGNSS field trip, so I was anxious to attend this past weekend’s joint trip between the Entomology and Nature Photography Groups to visit a private restored tallgrass prairie remnant located in extreme southwestern Washington County and named after Henry Schoocraft, who famously chronicled his journey through the Missouri Ozarks in the early 1800s and passed within a few miles of this spot (if you’ve not yet read Schoolcraft’s journal, I highly recommend this natural history classic!). The landowner, a restoration ecologist for Shaw Nature Reserve, has been using prescribed burns and selective thinning over the past several years to restore the 70-acre tract of upland forest, former cropland, and grassland remnants to their presettlement character. Stupidly, I did not bring my main camera, preferring to focus instead on collecting rather than photography. In hindsight, I would have been much better served had I had my camera, as the beetle groups that I study (Buprestidae and Cerambycidae) tend to be scarce at this time of season in Missouri, while interesting subjects for photography in other insect groups abound. As far as photos go, my iPhone would have to suffice.

We arrived a bit after mid-afternoon and spent the bulk of the remaining daylight hours in the prairie remnant. Florally, it was one of the most diverse prairies I’ve ever seen, especially in this part of the Missouri Ozarks. One plant in bloom that was new to me was Liatris scariosa (devil’s bite blazingstar), distinguished from the similar L. aspera (also in bloom) by its flower heads on long stalks and with mostly flat phyllaries.
The first insect of interest that I found was the white fluffy early-instar caterpillar of Megalopyge crispata (black-waved flannel moth). The hairs of all species in this genus are venomous in the larval stage, and interestingly the later instars of a related species (M. opercula) resemble a tiny Trump toupee (look it up!).

Also present were Neotibicen auriferus (prairie dog-day cicada), whose whining, metallic songs filled the air. Normally very skittish and difficult to approach, I managed to snag one on the trunk of a small persimmon tree in the middle of the prairie.

As afternoon progressed to evening, I went back down from atop the ridge and visited a small calcarous fen—a unique wetland habitat created by seepage of calcareous groundwater that results in saturated, low-oxygen soil. Fens often support unique plants, and in this one I found Solidago patula (swamp goldenrod). I’ve never seen this plant before, so I was a bit disappointed it was not yet in bloom, but I marveled at an enormous, darkly colored banded fishing spider (Dolomedes vittatus) sitting on one of the plants.

After dinner we set up several light stations, including one up in the restored prairie remnant. Despite the warm, humid conditions, I had little optimism that we would see much of interest at the lights due to the near-full moon shining brightly in the cloudless sky. This was mostly true, although I did collect a few ceresine treehoppers and weevils from the lights. Additionally, a few small but pretty moths warranted a photograph or two.

The truly interesting finds, however, would come in the form of caterpillars on the foliage of nearby trees. Three species of slug moths (family Limacodidae)—among the most bizarre-looking of caterpillars, and all of which can sting—would be found. Two of them were new to me—a beautifully lichen-colored Euclea delphinii (spiny oak slug moth), and the nearly amorphous Apoda y-inversa (yellow-colored slug moth). The third species was the striking Parasa indetermina (stinging rose slug moth)—always a treat to see!

Other striking caterpillars were found as well: Amorpha juglandis (walnut sphinx) and Ceratomia catalpae (catalpa sphinx)—adults of each also visiting the lights, Anisota virginiensis (pink-striped oakworm), Automeris io (io moth), Acronictasuperans (splendid dagger moth), and Halysidota tessellaris (banded tussock moth). Some of these were photographed in situ, but most were brought back to camp for photographs under more controlled conditions.

Another interesting observation near the light in the prairie was a Neoconocephalus ensiger (sword-bearing conehead katydid—family Tettigoniidae) final-instar nymph molting to adulthood. At the time that I photographed it, the antennae were pulled taught—almost but not completely pulled free from the exuviae.

Alternate title: “The importance of authoritative identification and voucher specimen information when documenting a new occurrence of an exotic species.”
For many years now (indeed, decades!), I have been assembling a “Catalogue of Buprestoidea of North America, Mexico, Central America, and the West Indies.” Still a work in progress, it serves as a personal database of literature citations for all species of Buprestoidea occurring in that region—both native and introduced, along with full synonymies, information on type specimens and repositories, distributions, host plants (larval, adult, and flower), natural enemies, and attractants, and comments on erroneous reports and taxonomic issues. The relatively recent appearance of two other catalogues for this superfamily—one by Nelson et al. (2008) for North America north of Mexico, the other by Bellamy (2008–2009) and worldwide in scope—might seem to render this effort duplicative. Nevertheless, both catalogues contain errors and omissions that should be corrected, and numerous additional papers on the taxonomy, nomenclature, and biology of species of Buprestoidea have been published in the years since the appearance of these catalogues. Additionally, my vision of the eventual published version of my catalogue includes full synonymies and more detail in the aforementioned sections. Don’t look for it to be published anytime soon, as it is nowhere close to ready—perhaps it will prove to be my final magnus opus, much as the Nelson et al. and Bellamy catalogues capped the careers of their respective authors.
Last December, whilecomparing provincial records in my database with the second edition of Checklist of Beetles (Coleoptera) of Canada and Alaska (Bousquet et al. 2013), I encountered in the latter an entry for the Palearctic (Europe and Asia) species Buprestis haemorrhoidalis in British Columbia. This was news to me, and I quickly checked the Nelson et al. and Bellamy catalogues, neither of which included North America in the reported distribution of this species (the Bellamy catalogue did report an introduction of the species to South America). The Bousquet et al. checklist post-dates the Nelson et al. and Bellamy catalogues by five years, so I assumed the supporting record would be found within one of the papers from within that time period that I had not yet databased; however, no such paper was found.
I then turned to my old friend Google and searched “Buprestis haemorrhoidalis British Columbia”, and the very first result was a placeholder page for the species at the popular insect website BugGuide (Belov 2017–2023). No North American observations had yet been posted to the page, but two references were cited—the aforementioned Bousquet et al. checklist, and a paper by Humble & Allen (2006). The link to the paper was nonfunctional, but I found a PDF at the Purdue University website (see link in citation below). In the paper, B. haemorrhoidalis was included in a list of invasive species reported to be “established” in Canada, giving 1992 as the date of introduction. No information regarding the source of the record or the existence of voucher specimen(s) was given, but the authors’ affiliation with the Pacific Forestry Centre in Victoria, British Columbia hinted at this being the basis of the listing in the Bousquet et al. catalogue. Neither the Nelson et al. nor Bellamy catalogues cited this reference, but its publication date (2006) is close enough to the two catalogues (2008) and the venue obscure enough (not an entomology journal) that the omission is not unexpected. A more exhaustive literature search turned up nothing but a single more recent summary listing of the record by Ruzzier et al. (2023), citing Humble & Allen (2006).
Unable to find anything online, I emailed the corresponding author (Leland Humble), but the message bounced back as undeliverable. This prompted me to reach out to several current buprestid workers, all of whom concurred with my presumption that this must—in the absence of any supporting evidence to the contrary—represent a non-established interception or a misidentification of a native species. One of them, Eduard “Edo” Jendek (Bratislava, Slovakia), an expert in invasive Buprestidae, contacted Jon Sweeney (Canadian Forest Service, Atlantic Forestry Centre), who informed him that Humble was deceased and suggested sending an inquiry to Meghan Noseworthy, currently research manager at the Pacific Forestry Centre arthropod reference collection (PFCARC). In response to my inquiry, Meghan informed me that a specimen under the name B. haemorrhoidalis was, indeed, listed in their collection database. She was able to locate the specimen and graciously arranged to have it sent to me on loan so I could examine it and confirm or correct its identity. When the shipment arrived, I opened the box and saw this:
Unit tray from the Pacific Forestry Centre arthropod reference collection containing putative voucher specimen of “Buprestis haemorrhoidalis.”
Comparison of the specimen to a series of B. haemorrhoidalis in my collection quickly revealed it is not that species. This was no longer an ID confirmation, but an ID correction—almost surely a native North American species. Remarkably, the first clue to its true identity was found on the labels attached to the specimen itself—the initial identification label by “A.Davies” (undated) as “Buprestis haemorrhoidalis” had been repositioned upside-down on the pin, and a second identification label by “R.L.Westcott ‘07” as “Buprestis subornata (LeC.” [closing parenthesis missing] was placed beneath it. As expected, the specimen agrees in all respects with a series of B. subornata in my collection. While B. haemorrhoidalis superficially resembles B. subornata, it differs in its well-defined, serially punctate elytral intervals (B. subornata has poorly-defined, impunctate intervals) and its smoother, shinier elytral surface compared to the latter species. Indeed, the two are placed in separate subgenera—B. haemorrhoidalis in Ancylocheira, and B. subornata in Buprestis s. str.
Putativevoucher specimen of “Buprestishaemorrhoidalis.” In reality, the specimen represents the North American native species Buprestis subornata (LeConte, 1860).
Examination of the specimen labels leaves little doubt that this specimen is the basis of the Humble & Allen (2006) report of B. haemorrhoidalis in Canada—the specimen resides in the PFCARC (the institute with which L. Humble and E. Allen were affiliated), and the reported date of introduction (1992) matches the specimen date of collection. There also can be little doubt that this specimen is the basis of the Bousquet et al. (2013) report of B. haemorrhoidalis in British Columbia—the label indicates collection in “Kelowna B.C.”, and the initial identifier (A. Davies) is the author of the Buprestidae chapter in the first edition of the Canada checklist (Davies 1991) and a coauthor of the second edition.
Labels that had been placed on the voucher specimen show that its identity was corrected shortly after the record was published (the Davies label was repositioned upside-down on the pin). 
This examination refutes any notion that B. haemorrhoidalis has ever been introduced to or established within North America. However, it also highlights the problems that allowed a misidentification to not only be reported in the literature, but also accepted and propagated. The initial erroneous identification by Davies is puzzling—not so much because it happened (erroneous identifications happen all the time), but because it was identified as an exotic species with no known prior occurrence in North America. The identification of any exotic species for the first time is a significant finding that should raise alarms and be immediately confirmed by a recognized specialist with taxonomic expertise in the group to which it belongs. While this did eventually happen with Westcott’s corrected identification in 2007, it was not before the erroneous identification had already been introduced to the literature by Humble & Allen (2006).
The fact that the erroneous identification was even published at all is itself problematic—there was no prior, peer-reviewed publication to support its summary listing in a review article published in a non-entomology journal, nor was there any citation of specimen data or voucher location to address the absence of such. The use of the word “established” to characterize the presence of the species in Canada is also curious, although I note that the authors were mycologists, not entomologists, and may not have appreciated the significance of that term in the context of invasive exotic insects. (The more appropriate term, erroneous ID notwithstanding, would have been “apparently introduced or mislabeled”.)
The acceptance of the erroneous report by Bousquet et al. (2013) is yet another puzzle, as the identification had been corrected by Westcott—a recognized expert of Buprestidae—six years earlier. Obviously, the PFCARC neglected to correct the listing of the specimen under B. haemorrhoidalis—both in their collection database and in the collection itself—despite this correction (now 17 years ago!). I also note that the Canadian National Collection website lists a specimen (record #CNCCOLEO00091957) with identical label data, but again only the initial identification as B. haemorrhoidalis is mentioned—the corrected identification as B. subornata is not. Since Davies (a coauthor of the second edition) made the initial identification, perhaps the remaining authors had no reason to doubt it. Nonetheless, the reported occurrence of an exotic, apparently invasive species with no supporting reference documenting the circumstances of its collection should have triggered confirmatory follow-up before its inclusion in the updated version of the checklist.
Had any of the above circumstances been avoided, the erroneous report of an exotic invasive species established in North America would not have been propagated in subsequent literature (i.e., Ruzzier et al. 2023) or on a popular insect website (i.e. BugGuide). Let this serve as a cautionary tale to current and future entomologists, especially those with an interest in invasive species and cataloguing efforts. I have a (much shorter) corrective note about this in a soon-to-be-published paper that will likely set the record straight among most North American buprestid workers. However, the erroneous record could still be propagated by those not interested explicitly in Buprestidae (e.g., invasive species specialists) and, thus, may be unlikely to encounter my corrective note. As they say, it’s hard to unring the bell.

Welcome to the 15th “Collecting Trip iReport” covering the second 11-day insect collecting trip to eastern New Mexico this year. This trip, which took place on June 17–28, was a follow-up to “Act 1” on May 14–25 with the purpose of servicing “jug traps” placed on the first trip. Joining me this time was Rich Thoma, who has accompanied me on more field trips than anyone else over the past four decades! Initially I had planned to pick up the traps that I’d placed on the first trip; however, I found the idea of sampling just the early part of the longhorned beetle season to be unsatisfying and decided shortly before the trip to service the traps but leave them in place for another sampling period and make a third trip later in the season to retrieve them. It will be a coupe of months, however, before I can make that third trip, meaning the traps will be out for much longer than normal and making desirable any modifications that I can make to extend their effectiveness. To that end, I prepared larger bait bottles (500-ml capacity versus 250-ml) and purchased enough propylene glycol to fill the jug reservoirs to the limit of their capacity (1250 ml versus the 900 ml used previously). The prototype trap that I made prior to the trip seemed to work, so it was only a matter of deploying them in the field and keeping my fingers crossed. Similar to the last trip, we ended up making 16 visits to 16 different localities—15 in New Mexico, one in Oklahoma (versus 13 localities previously), but unlike last trip we also spent time at two localities (one in Oklahoma, one in Texas) strictly for hiking and observation.
Salt Plain National Wildlife Refuge Alfalfa County, Oklahoma Rich and I are repeating the 12-hour drive from St. Louis to Black Mesa State Park in the northwestern corner of the Oklahoma panhandle that I did last month with Mike Arduser. I decided not to do the dreadful I-44 through Tulsa route, even though it is quicker, because I really just dread the boredom of the interstates and especially dislike the traffic and highways around Tulsa. Instead, we cut into southern Kansas at the last mile in Missouri and skimmed the bottom edge of that state—a very scenic route—until dropping down into Oklahoma once we’d gotten past I-35. Since we were passing by Salt Plain National Wildlife Refuge and it had been probably ten or more years since we’d stopped there, we decided to take a look around the alkaline flats to see what tiger beetles we might see.

There was also the occasional individual of the dreadfully pedestrian Cicindelidia punctulata punctulata (punctured tiger beetle), but none of the other alkaline flat specialties like Eunota circumpicta johnsoni (Johnson’s tiger beetle) or Eunota togata globicollis (white-cloaked tiger beetle) were seen.

It was dreadfully windy (as it often is in the wide open reaches of the vast Great Plains), so nothing was found on the few flowers that were found along the trail. Not wanting to delay our arrival at Black Mesa this evening too much, we cut the visit short and continued on the way.

The rest of the drive along the northern edge of Oklahoma was stunningly beautiful. Not only did we get to enjoy the non-interstate landscape and the more intimate experience it provided, but we also watched a spectacular storm system as it bloomed across the skies to the north and west. Radar and forecasts calmed our fears that we would experience it more directly—it was slated to sweep across Kansas but not touch Oklahoma, letting us admire stunning vistas of golden fields of sunlit wheat against a backdrop of blackened clouds …

Black Mesa State Park Cimarron County, Oklahoma By the time we reached Black Mesa State Park, it was well dark, but we got camp set up with enough time left to enjoy a beer and relax a bit before walking the roads to see what beetles might be out and about. I was hoping to see Amblycheila cylindriformis (Plains giant tiger beetle), but our finds were limited to darkling beetles (Eleodes suturalis and E. longicollis)…

Satisfied we’d given the area a good enough look, we settled into the fly-less tent to admire the stars while falling to sleep in the cool night air.

After resting up a bit, we decided to head back out of the park (and, thus, into New Mexico) to nearby Queen to replenish our ice and liquids and then visit the Lincoln National Forest’s Sitting Bull Falls Recreation Area. Both of those decisions did not work out as planned. The (only) convenience store in Queen was closed, despite the posted hours of business stating they were open until 5 pm, so the little ice that we had left would have to last until the morning. Then, when we arrived at the turn off to Sitting Bull Falls, we saw that the area closed at 4 pm—less than an hour away. We drove to the entrance anyway, where we found a parking area for a trailhead and looked around a bit. The area was very lush, obviously having enjoyed the recent rains, but there was almost no insect activity to speak of. Our already tired legs didn’t help with our motivation, and we decided to call it a day and head back to the park.
Day 2
Conditions turned quickly and unexpectedly on us! There was no hint of rain in the local forecast, but we awoke at 2 am to drizzle coming through the roof of the tent and quickly installed the rain fly. It rained the rest of the night—sometimes heavily, and while we were able to eat breakfast and then break camp in the morning before heavy rains returned it was still a cold, windy, drizzly experience. (I’ve now camped here seven times in the last two years, and this is the fourth time I’ve experience blustery cold and/or rainy weather here!) We had planned to collect during the morning at our favorite nearby spot—a sandstone outcropping just east of Kenton where I have collected five new state records—two cerambycids and three buprestids—in the last few years. Steady rain and cold temperatures, however, cancelled those plans, and radar and forecasts made it appear we might spend the next two or three days dealing with such unless we made significant progress towards the south. We decided to go to our next stop—Mills Rim Campground—where I had the first set of my traps to service, and then see how conditions developed before deciding whether to stay or move on.
Mills Rim Campground Kiowa National Grassland Harding County, New Mexico Rains did let up as we approached Mill Rim Campground and while we were there, but only temporarily while cool (almost cold!) conditions persisted. We stopped on the road into the campground to check out a pile of recently-cut juniper wood hoping to see woodboring beetles, but all I saw was a solitary bee fly (though one I’d never noticed before—Aphoebantus sp. (bee fly—family Bombyliidae).

In the campground, I was pleased to see that all three traps were still in place, though the bait and reservoir liquid were both completely gone in them. I was also pleased to find that the traps redeployed nicely with my changes (larger 500-ml bait bottle and a larger volume—1250 ml—of diluted propylene glycol in the reservoir).

Catch results, however, were a bit disappointing. The SRW and SRW/EtOH traps had lots of moths and Euphoria fulgida but no cerambycids, while the EtOH trap had nothing but a single E. fulgida (I suspect the trap reservoir may have been “dumped” during high winds). The white bottle trap had a few Acmaeodera spp. and about 12–15 bees, which I collected for my mellitologist friend Mike Arduser.
The “rim” of Mill Canyon.
Once all the traps had been serviced, the continuing rain and cold conditions made it an easy decision to keep moving south and forget about trying to collect or camp here!
“San Jon Hill” Quay County, New Mexico The forecasts showed temperatures about 10°F higher once we got as far south as San Jon, near which I had a set of traps that needed to be serviced, and about an hour further south was Oasis State Park where we would have a place to camp and possibly collect if the conditions were right. Conditions did indeed improve as we neared San Jon, with solid overcast skies beginning to brighten in the south and intermittent sun beginning to reach the ground. By the time we reached the spot where my traps were located, temps were well above 80°F and skies were partly sunny—but what wind!
We set about servicing the traps, and here I had another concerned calmed—this was the last place I had set traps last month, so the traps were the older style body made from shorter water jugs—nevertheless, the larger bait bottles fit inside the traps (barely), and the reservoir was able to handle the higher liquid amount. Results for the SRW and SRW/EtOH traps were nearly identical to Mills Rim—both filled with lots of moths and Euphoria fulgida but no cerambycids (or at least very few—I did see at least one as I dumped the catch into the plastic bag). Again, I bagged the catch from both traps for later sorting. The EtOH trap, unfortunately, was down—the hanging rope was cut, apparently snapped due to rubbing against a branch in the wind. Just in case the culprit was hominid, however, I installed a new trap in a different nearby tree where it couldn’t be seen from the previous spot. The white bottle trap was absolutely overwhelmed with both Acmaeoderamixta and A. ligulata (and hopefully other species as well) and bees (for Mike), which I bagged for later sorting. We spent another hour or so collecting, but it was not terribly productive for me—beating Prosopis glandulosa produced lots of leaf-footed bugs and tiny beetles from the flowers, but I kept only a single Cleridae. I also beat a lot of oaks (Quercus mohriana and Q. x undulata) hoping to find more Brachys barberi (got one last time) but found nothing except a couple of elaterids. I also swept several stands of Quercus havardii but found nothing but grasshopper nymphs. All of the Opuntia camanchica (tulip pricklypear) from which I had collected Acmaeodera spp. last time were bloomed out, but I paid attention to them anyway hoping to see cactus beetles and finally found one Moneilema armatum on the pad of one.

I also encountered a single plant in flower, from which I collected one Trichiotinus texanus (Texas flower scarab) and a couple of Euphoria kernii (Kern’s flower scarab). There were a few A. mixta on various flowers (primarily Thelesperma megapotamicum and Xanthisma spinulosa), but I let Rich have them and didn’t see any other species. Having satisfied ourselves that we’d gotten a good enough look, we continued south towards Oasis State Park.

Oasis State Park Roosevelt County, New Mexico Nice conditions and brightly sunlit windmills followed us during the 90-minute drive further south to our campground near Portales, with a spectacular bonus sunset greeting us upon our arrival.
Sunset on the Sand Dune Trail at Oasis State Park.
I quick ran over to the Sand Dune Trail to get a photo, knowing that colored sunsets of that sort are fleeting at best, and then we set about putting up camp and grilling some brats. Afterwards, we began our night walk to see what critters might be out and about, but first I wanted to go to a small, nicely-lit building near the restrooms to see what the lights may have pulled in (despite the presence of nearly full moon). At first I found only a few tenebrionids, though in nice variety and including one of the fantastically explanate tenebrionid Embaphion muricatum, and a crummy Cicindelidia punctulata chiricahuae (western subspecies of the punctured tiger beetle), but then I found several bolboceratine geotrupids—the large chunky Bradycinetulus fossatus, and several of the smaller Eucanthus sp. Then I saw a big something crawling frenetically nearby in the road, went over to look at it, and saw that it was a female Prionus arenarius—what a find!

There wasn’t much on the Sand Dune Trail loop, but another Embaphion muricatum on the loop and dead but perfectly intact specimens on the road through the campground of yet another Bradycinetulus fossatus and female Prionus arenarius—the two best finds of the night—made the walk worth it. Afterwards, we returned to the building lights to see if more Prionus (male or female) had arrived, but by then it was close to midnight and the cool night air had a decided “things are over” feel to it.

Day 3
We stayed dry all night and awoke to sunny skies early, but clouds increased as the morning progressed and the forecast called for rain starting around 10 am. Rich wanted to look around while we had the chance, but I’d seen enough and instead worked on my notes while he was out and about. Eventually we broke camp and headed out—no sooner had we done that then the rain started! We eventually learned that all this rain we were dealing with had a name—Tropical Storm Alberto, which had made landfall the day before in Mexico and was throwing moisture everywhere in its wake. At least it now made sense to us why the entire eastern half of the state was so persistently rainy no matter where we went. As we drove towards our next stop (Mescalero Sands Recreation Area), we formulated Plan B to blast all the way south and west to near Las Cruces, which seemed to be escaping the rains, and hole up there for the next two days until things cleared up. However, we arrived at the dunes under partly sunny skies and nicely warm, though quite windy, conditions.
Mescalero Sands Recreation Area Chaves County, New Mexico The first order of business was to service my jug traps, which I had hung in the Sapindus saponaria ssp. drummondii (western soapberry) stands that dot the highway rights-of-way along the edge of the sand dune area. This has been one of my best collecting spots over the years—being the only place where I have reliably found in numbers the beautiful lime-green Agrilus sapindi in association with the soapberry. Unfortunately, all three jug traps were empty—compromised in some way by the strong winds that seem to persist in this area. One trap was “spun around” the branch on which it was hanging, another dropped when the rope came undone, and the third simply swung wildly in the wind, throwing the bait bottle and emptying the reservoir. I elected not to rehang any of the traps here, having little confidence that I would be able hang them any more securely than I had already done. It’s a shame, because I was really interested in seeing what longhorned beetles the traps would pull, not only from the soapberrys in which they were hanging but also from the surrounding Quercus havardii (shinnery oak)-dominated sandhill shrubland. Right on queue, however, I found several A. sapindi and one Neoclytus mucronatus vogti on the soapberries as I was retrieving the last trap.

Also, though not an insect, I noticed a partial mammal cranium (missing the maxillae) half-buried in the sand. I picked it up and looked at it, thinking it might be a javelina because of the far rear-situated cranial crest. Then I noticed the other half of the cranium lying teeth-upwards nearby. The two pieces fit together nearly perfectly (some minor warping notwithstanding), and the large canine tusks convinced me even more so that it represented a javelina. I bagged it and will glue it together when I return home for display in my “bone shelf”!

As I started heading back to the car, I saw—and missed!—a Chrysobothris mescalero on the shinnery oak in that spot—damn! Happily, I did manage to sweep another individual from the plants back near where we parked. Continued sweeping failed to produce any more individuals, but what I really wanted to find was Agrilus hespenheidei—also beautiful green but completely unrelated to A. sapindi and which I have collected only sparingly in the past but failed completely to find on my most recent visit. I swept the grasses along the roadside and found none (for now!), then went into the recreation area entrance to retrieve the white bottle trap—it was overwhelmed with Acmaeodera spp. and bees, which I bagged and will sort later. Very little else was seen, and by the time I returned to the car Rich was satisfied with the myriad pollinating insects he’d collected off the soapberry flowers and specimens of A. sapindi and C. mescalero that he’d swept. It was still early enough in the day after refueling and rehydrating that we decided to visit the dunes proper and see what might be out.
Distant sand dunes frame an even more distant escarpment.
I wasn’t very optimistic about collecting in the dunes, given that paucity of insects seen in the shrubland along the highway and just inside the entrance, but there was still enough time left in the day to spend time here and not enough to move on to the campground near Roswell and collect there. For much of the time, my pessimism prevailed, as I did a bit of sweeping here and there and saw (but did not collect) only the occasional mutillid (velvet ant) and tenebrionid (darkling beetle). The scenery was nice, however, and the temperatures comfortable, and at the furthest point out we had a bit of fun “working” a common blotch-sided lizard (Uta standsburiana) female into a place where we were able to photograph her.

On the way back, I happened to notice a buprestid sitting on the dried stem of Sporobolus giganteus (giant dropseed) and realized it was the one buprestid I was hoping to collect here—Agrilus hespenheidei! This led to a renewed round of sweeping in all the neighboring plants and others along the way back, resulting in several interesting captures such as an ataxiine cerambycid, one Macrosaigon sp., two Selenodon sp., and a couple of small weevils—but no additional A. heapenheidei! I also found an interesting little Eusattus sp. tenebrionid on the sand, so it was nice leaving the place knowing that I would not be “skunked” for the first time on the trip!
We drove through rain on the drive going west towards Roswell, and shortly afterwards I saw a male Texas brown tarantula (Aphonopelma hentzi) crossing the highway. I did a U-turn and went back to it to 1) move it off the highway so it wouldn’t get run over and 2) take photos of it. Several cars passed over it as we were backtracking, but fortunately none ran over it, and we had a clear road to turn around once again and pull over. We took a few quick photos while it was still on the road—one amazingly capturing the newly formed rainbow in the background—before a semi bearing down from the distance forced us to quickly “guide” it off the road. It really wanted to continue to the other side, so we had to be quite insistent on forcing it off the road, and after traffic cleared we coaxed it into a jar and delivered it to the other side of the highway all the way to the fenceline.

Bottomless Lakes State Park Chaves County, New Mexico We arrived at the park with some good daylight to spare and snagged the choicest campsite in the entire campground (why the people at the two already occupied sites didn’t take it is beyond me!), explored our new home for a bit, and then set about putting everything in place.
Premier campsite at Bottomless Lakes State Park.
As soon as we finished, we noticed a rain shower in the distance and debated the direction it was moving. I thought it would pass to our east, but within minutes it was raining—and a few minutes later it was pouring! But we watched in comfort under the large metal shelter covering our table and admired the incredible rainbow that formed over the canyon wall bordering the eastern side of our campsite.

Eventually the rain stopped and we fired up some burgers on the grill. Wildlife competed for my interest while the burgers were cooking, apparently brought out by the fresh rain and coming darkness. These included a kangaroo rat (Dipodomys sp.) and a red-spotted toad (Anaxyrus punctatus).

The fresh rain, coolish temps, and near-full moon made setting up the lights to attract insects out of the question, but after dinner when darkness had fully settled we walked the road through the campground to look for nocturnal beetles. I was hoping to find Amblycheila picolominii (Plateau giant tiger beetle), one of which had had found up on the rock slope the last time I was here, but I wasn’t thrilled with the idea of clambering over steep, wet rocks in the dark and settled for the pavement up to the beginning of the tent campground and back. Large tenebrionid darkling beetles were expected, thus the two we saw were no surprise, but what did surprise and delight us was another male tarantula—and not the common Texas brown tarantula (Aphonopelma hentzi) but the much less commonly encountered Chihuahuan gray (A. gabeli)! This was a delight and becomes the fourth species of tarantula I’ve found in the wild. We trailed it back and forth as it ambled along the road trying to get good photos, but it never stopped long enough to allow such. Eventually it did stop along the side of the road, where we took some “okay” photos before moving on.

As we began to walk away, I had second thoughts and decided to try for one more frontal portrait shot, but I had to move a little plant stem that was obscuring the view. I did this as carefully as I could, but the tarantula sensed something and suddenly took off like a shot. I followed as it bolted across the road, where suddenly it stopped and hunkered down right out in the open—as if it had fled the danger and was now willing to wait it out for a bit before resuming its wandering. At that point, I was able to easily take the frontal portrait photos that I desired—all that following and frustration, when all I really needed to do was scare it and wait for it to stop running.
The sight a cricket does not want to see!
By the time we returned to the campsite, I was exhausted and turned in early (rare for me!).
Day 4
It started raining again around 2 am and didn’t really let up until after noon. We took advantage of the chance to update our field notes and process specimens before going into town to pick up a few supplies. It was still raining when we returned later in the morning, but only lightly and allowing us to stop at the cenote next to the visitor center. I never took the opportunity to look at one of the cenotes last time, so this was my first actual look at one of them.

We headed back to our campsite and continued working on our field notes and adding captions to our photographs until the rain finally stopped around 1:30 pm, and by 2:30 conditions had dried out and temps warmed enough to warrant going out and collecting.

I started out by hiking the ravine from our campground down to where it drained into a cenote (Pasture Lake) near the adjacent campsite and found lots of Sphenophorus aequalis (clay-colored billbug) on the ground near and within a stand of Schoenoplectus americanus (American three-square bulrush) along the lake margin where they were walking about, mating, and burrowing into the soil at base of the plants—especially dead remnants.

I also scoured the barren alkaline soil along the lake margin for tiger beetles and found a couple of Tetracha carolina (Carolina metallic tiger beetle) elytra and several adult Cicindelidia ocellata ocellata (ocellated tiger beetle). Before leaving the lake area I also snagged an Acmaeodera gibbula in flight and then wandered over to the area where I found Atriplex canescens (four-winged saltbush) infested with longhorned beetles (Amannus sp., which I still have not identified). I was hoping to see adults now emerged and in the plants, but none were seen. I also kept an eye out for buprestids on the Ephedra torreyana (Torrey’s jointfir) but never saw anything. I was starting to think buprestids were (puzzlingly) out-of-season as I wandered up into the picnic area where I found several things last time and quickly saw a beautiful Gyascutus planicosta obliterata adult sitting on the foliage of A. canescens. Over the next couple of hours I would collect a handful of these beautiful beetles. It’s been a long time since I’ve seen members of this genus in the field, and I’d forgotten whether they were skittish or sluggish—this one was the latter and let me take a nice close photo before obligingly dropping into the net. Probably it depends on temperature, as I remember collecting these in Texas in blazing hot conditions and seeing them zip off instantly and fly far into the distance upon sensing my approach. Today’s temps were much more modest (thankfully), so the adults were rather easy to collect.

As I looked for Gyascutus on the slopes and around the picnic area, I took the opportunity to beat the mesquites (Prosopis glandulosa)—especially those in flower. [Edit: the genus Prosopis was recently split up into several genera, with P. glandulosa being assigned to the new genus Neltuma. I don’t reject this new placement but will use the older, more familiar name on this blog until the new name receives greater acceptance.] Most of what I saw were leaffooted bugs, but I did pick up one more A. gibbula, one Acmaeoderopsis hulli, a few Epicauta sp., and a couple each of a darnine and a centrotine membracid. I also continued to inspect A. canescens plants for signs of infestation by Amannus but was unable to find any larvae or unemerged adults in the few living plants that I broke apart when they exhibited emergence holes. What I did find, however, was an Acmaeodera sp. partial cadaver of an adult that had failed to emerge. I was able to retrieve its elytral shield (Acmaeodera sp. have fused elytra, which they lift up during flight rather than spread apart like most other buprestids), and hopefully it will be enough to enable a species identification and a confirmed larval host plant association. By the time I looked at the last plant, it was going on 6 pm. I was hot, thirsty, and hungry, and I had a lot of specimens from previous days still to process, so I headed back to the campsite.

It took a couple of hours to write up my notes and complete processing of the specimens I’d collected from the bottle trap yesterday at Mescalero Sands (I’m guessing there were at least 100, if not 200, Acmaeodera specimens as well as a few dozen bees for Mike). As darkness descended, the full moon rising in the east dampened any enthusiasm I may have had for putting up the full UV/MV (ultraviolet/mercury vapor) light setup, but what we did do was much simpler: just lay a UV light on a white sheet on the ground. Despite the increasingly intense moonlight, tiger beetles began to show up on and near the sheet. Eunota circumpicta johnsonii (Johnson’s tiger beetle) was the first to arrive and turned out to be abundant.

Jundlandia lemniscata repaptisata (rouged tiger beetle) also was common, but it took longer for them to come in.

What I was most recited about, however, were the two individuals of Cicindelidia tenuisignata (thin-lined tiger beetle) that showed up.

Rich also found a Tetracha carolina (Carolina metallic tiger beetle running on the ground nearby. Eventually we decided to walk the road—Rich was hoping to see snakes, and I was hoping to see Amblycheila picolominii (Plains giant tiger beetle), a single individual of which I had seen during my previous visit up on the gypsum/red siltstone slope bordering the campground. Neither of us saw what we were hoping to see, or anything else for that matter, so we returned to the campground. I still had Amblycheila on my mind, however, so I decided to go back up onto the slopes where I had seen the species before to at least give myself a chance of seeing it again. I clambered semi-directly to the spot where I had seen it before, continued across the slope to the northern canyon limit, and then went downslope a bit to traverse the again in the opposite direction. Right as I started across again, I found one ambling across the rocks much as the previous one I’d seen. This charged my motivation, and though traversing the slope several more times proved fruitless, I was still a happy camper!

After returning to the campsite, I decided to explore the steep, narrow, canyon ravine behind our campsite, which I still had not yet done, and picked my way over the rocks to as far as I could go. I kind of expected/hoped to see Amblycheila, but not really—just wanted to explore the unique canyon feature. Near the furthest point I shine my headlamp on the steep clay slope at the bottom of the canyon wall and saw a Texas brown tarantula (Aphonopelma hentzi). It was not, however, just any ol’ Texas brown, but a female—recognizable as such by her relatively shorter legs and larger abdomen and also the fact that she was sitting right next to her burrow. I’m sure Madam will be rightly excited when she finds out we have a new pet named Bertha!

You’d think this would be the perfect swan song for the evening, but as I picked my way back down the canyon floor I spotted another A. picolominii, which made me want to keep exploring even more. This I did, going down to the spot along the Bluff Trail where I’d had so much success with Gyascutus earlier in the afternoon, but the only thing all this extra walking resulted in was an even later bedtime. Nevertheless, I couldn’t have been more pleased at finding six tiger beetle species during this visit (after finding only the single Amblycheila last time and thinking I was losing my tiger beetle mojo!).

Day 5
Despite the great success we’d had collecting insects in Bottomless Lakes State Park the previous day or so, there was one thing I was glad to be leaving—the house flies! They swarmed our campsite in numbers I’d never seen before, relentlessly landing on everything including our supplies, hands, faces, etc. it then took an hour or so getting all of the thousand or so that had infiltrated our vehicle out of the vehicle as we drove towards our next stop in the southernmost tract of the Lincoln National Forest in Eddy Co. Before leaving Roswell, however, we had to stop by the “Alien Welcome Monument” at the edge of town. I was disappointed to see that my version of “Kilroy was here” graffiti from last time’s visit was gone (apparently the monument gets painted over periodically), so I added it back.

X Bar Rd Eddy County, New Mexico The gradual ascent from the desert floor up into the pinyon/oak/juniper zone of the mountains is among the remotest-feeling that I have ever experienced, and just shy of the National Forest boundary we found our next spot. My biggest concern was whether the area was still experiencing drought conditions, but we were happy to see that the area has actually received rain—enough in the last day or so to thoroughly wet the soil. We could see it in the way the area looked, with most of the oaks and acacias having sprouted new leaves and the surrounding slopes exhibiting a greenish “cast.” The catches from all three traps were similar to each other and to what we had seen further north—i.e., mostly moths, but without the Euphoria fulgida. The SRW and SRW/EtOH traps seemed to have caught more than the EtOH trap, but the difference was not as large as further north. I did see a few elaphidiine cerambycids in the first two (as I bagged them for later sorting), but not many. I was hoping to see my primary target—Purpuricenus opacus, but I also knew that it may be a bit early for that species (and with the prevailing droughty conditions I may never see it). The white bottle trap, on the other hand, was loaded with Acmaeodera spp. and bees (the latter which I kept for Mike). Seeing the fresh foliage on the plants in the area, I set about beating some of them hoping things were starting to come out. Beating Senegalia greggii (catclaw acacia), however, produced only a few chrysomelids, as did beating the oaks (Quercus grisea—gray oak, I believe). There was very little in bloom, and sweeping the roadside vegetation produced nothing. Even the the few Opuntia camanchica (tulip pricklypear cactus) from which I’d collected a fair number of Acmaeodera spp. last time were devoid of flowers. Hopefully the recent rains will continue to trigger further beetle emergence, and my traps will collect some of these over the next two months.

Klondike Gap Rd, Hamm Vista Lincoln National Forest Eddy County, New Mexico We were optimistic about what we might see at this, my highest priority location for the jug traps, as it was from here that the west Texas specialty Purpuricenus opacus was recently reared from oak. Since the previous spot had seen rain, it seemed likely that this one had as well. Sadly, the landscape turned bone dry as we approached—dust on the plants with no sign of fresh foliage proving that it hadn’t rained for some time. My spirits were further dampened when I found the SRW trap down due to a frayed and broken rope. I rehung the trap with replacement rope (I always bring a spare trap and parts just in case) and was pleased to find both the SRW/EtOH and EtOH-only traps still hanging and—remarkably—with even more numerous trap catches than at the previous spot despite the lack of rain. Again, I did see a few elaphidiine cerambycids in each, but not many, and not a single scarab. The real surprise, however, came with the white bottle trap—literally hundreds of Acmaeodera, perhaps three or four times as many as were in the bottle trap at the previous spot. There were even a couple of still-living beetles walking about on top of the mass of beetles that were testing the limits of the volume of propylene glycol in the trap, suggesting that the beetles are currently active even with the dry conditions—but where are they?! There are no flowers to speak of, and beating produced nothing, yet the beetles must be flying about. All I can do is hope that conditions will improve sometime over the next two months that the traps are out and that they will be able attract whatever emerges whenever that happens.

Dog Canyon Campground Guadalupe Mountains National Park Culberson County, Texas Last month when I came here with Mike, our only reason for coming here was that it was a campground close to my trap localities where we could spend the night after setting the traps and then move on the next morning. When we arrived, however, we were immediately captivated by the stunning beauty of the canyon, and we decided that my next trap run should include an extra day to allow some hiking and exploring. That’s exactly what I planned for this visit, with two nights of camping bracketing a full day of hiking. The approach to the park is, in itself, spectacular, starting with a steep drop off the plateau and an expansive vista of the valley below—the highway leading to the park appearing as a thin, straight line between the massively tall canyon walls on either side.

A Texas welcome!
To our surprise, the campground was deserted—a marked contrast from last time when we were lucky enough to snag the last available campsite as Saturday night walk-ins. I can’t say I was disappointed, as that was my only real complaint about my previous visit. We weren’t totally alone, however—Kitty quickly stopped by to see us, at once skittish yet desperately wanting affection (and probably food). Of course, insect collecting is not allowed in a national park without a permit, so this visit was strictly for observing and (hopefully) lots of photographs. Both of these began shortly after we finished dinner (including Kitty, who scored a couple of sardines) and dusk had settled over the canyon when several large male Prionus californicus flew by at our campsite.

Afterwards, we decided to walk the gravel road through the campground and back past the state line to the paved highway in hopes of seeing snakes and other critters. We saw no snakes, but we say plenty of other critters—Xyloryctes thestalus (western rhinoceros beetle—family Scarabaeidae), a couple of Omorgus sp. (carcass beetles—family Trogidae), Scolopendra polymorpha (common desert centipede—family Scolopendridae), a juvenile tarantula (likely Aphonopelma sp.—family Theraphosidae), and my favorite—a couple of Amblycheila picolominii (Plateau tiger beetle—family Cicindelidae).

The most puzzling observation of the evening was two large ants apparently locked in tug-of-war combat—each momentarily gaining momentum and then just as quickly losing it to the other in a back-and-forth seesaw battle. Perhaps our local formicid specialist James Trager can shed light on this observation. Edit: James writes:
This looks like a couple of major workers of Camponotus sp. tussling at a territorial boundary of two colonies. These look like and might be C. americanus, but I’m frankly not sure about the ID from that location, without looking at specimens.

Day 6
Bush Mountain Trail Guadalupe Mountains National Park Culberson County, Texas Today’s plan was to spend the first part of the morning relaxing with coffee while catching up on the previous day’s field notes, then hike up Bush Mountain to Marcus Overlook. Gaining nearly 1000 feet in just under three miles, it would be enough of a challenge for either one of us, especially considering how slow Rich and I tend to be on our hikes due to constantly stopping to look at things.

As we passed through the grasslands beyond the horse corrals, we started seeing one of my favorite tiger beetles—Cicindelidia obsoleta (large grassland tiger beetle). The first two we saw were black, suggesting they were assignable to the nominate subspecies, but then we saw a green individual (that I got barely close enough for a crappy photo) which suggests subspecies C. o. santaclarae—a subspecies I’ve never seen in the field before and this spot surely on the eastern edge of its distribution (perhaps in an intergrade zone with nominate C. obsoletus). Perhaps in the morning before we leave I’ll go back and see if I can get a more acceptable photograph.

For a while the trail was not too steep as it followed a rocky wash, and most of the herbaceous plants were just beginning to produce new foliage (late June seems to me like an awful late start to the season!). As we ascended the mountain, the habitat turned from pinyon/juniper/oak woodland to alpine grassland with large ponderosa pines dotting the steep hillsides. The ascent was quite steep in places, causing us to stop frequently; however, our reward for doing so was the chance to take our eyes off our feet and instead admire the expansive vistas sprawling before us!

About halfway up I noticed what must have been a webbed-over (and thus occupied) tarantula burrow—my second tarantula burrow after having never seen one in my emite life.

Along a ridge near the top we found a very colorfully marked juvenile greater short-horned lizard (Phrynosoma hernandesi—the first horned lizard that I’ve seen in the field that was not a Texas horned lizard (P. cornutum).

The best find of the day, however, was the least expected—several tiger beetles whose identity I did not recognize and which proved to be Cicindelidia laetipennis! This particular population was, until very recently, considered a subspecies of C. politula (limestone tiger beetle) that was endemic to the Guadeloupe Mountains (C. p. petrophila—rock loving tiger beetle) and characterized by extreme variability in coloration despite its very small geographic range. Indeed, the two individuals I managed to get close enough to photograph (thanks to my new cell phone’s zoom function!) showed part of this variability—one being bright coppery-red and the other almost greenish. Molecular analysis, however, has shown that the population is instead conspecific with C. laetipennis, which was until then considered restricted to Mexico. Whether an endemic subspecies of a more common species or a distinct phenotype of a Mexican species, it was a thrill for me to see in the field for the first time.

At Marcus Overlook, we enjoyed a bit of a food and rest while viewing the expanse of mountains further west and south in the park, thankful that such immensely wild, unspoiled places still exist. The hike back down was more about the destination than the experience—the careful footing required to navigate the at times steep grades keep our eyes mostly on our feet, and by the time we reached our campsite at mid-afternoon we were ready for some rest, food, and rehydration!

After resting up a bit, we decided to head back out of the park (and, thus, into New Mexico) to nearby Queen to replenish our ice and liquids and then visit Sitting Bull Falls Recreation Area. Neither decision worked out as planned. The (only) convenience store in Queen was closed (despite the posted hours of business stating they were open until 5 pm), so the little ice that we had left would have to last until the morning, and when we arrived at the turn off to Sitting Bull Falls, we saw that the area closed at 4 pm—less than an hour away. We drove the road anyway and found a trailhead parking area just before the entrance that looked interesting enough to explore. The area was very lush, obviously having enjoyed recent rains, but there was no insect activity to speak of. Our already tired legs further lowered our motivation, and we decided to call it a day and head back to the park.
Hamm Vista Lincoln National Forest Eddy County, New Mexico On the way back, I had an idea—stop by the traps I’d serviced the previous day on Klondike Gap Rd (not too far off the main highway) and see if they were beginning to pull anything in. I checked only the bottle trap and the SRW/EtOH traps, and both had fresh catch—Acmaeodera in the former and Euphoria in the latter. Of course, I was hoping (but did not expect) to see Purpuricenus opacus, and though I did not see it after 24 short hours I remain optimistic that it will come to the traps in the next few weeks. While we were there, I noticed a particular oak tree (Quercus grisea—gray oak, I believe) alongside the road. Something about it said “Beat me!”, so I went back and got the beating sheet out of the car, beat another oak on the way back to the tree without seeing anything, and in the first whack of the tree I got Chrysobothris axillaris—an oak associate that I’ve only seen in west Texas. Of course, that motivated me to starting beating other oaks, but I never saw another beetle. Certainly not a productive stop, but at least getting C. axillaris made it worth the effort.

Dog Canyon Campground Guadalupe Mountains National Park Culberson County, Texas This being our last evening in the park, we brought out the bison steaks for a celebratory dinner, and they were quite good despite having to be cooked in a skillet over my tiny stove (no charcoal grills allowed!). Perhaps the “dirty skillet” imparted some flavor. Kitty joined the celebration, scoring four sardines for dinner instead of just two! Afterwards once darkness had settled, we walked the roads again hoping to see snakes and other crawlies, but there was far less on the roads this time compared to last night, with two notable exceptions—a Zopherus concolor (family Zopheridae), and a large male Prionus californicus (California prionid—family Cerambycidae), both on the trunks of the massive alligator junipers (Juniperus deppeana) that dot the campground. Perhaps the cooler and more blustery conditions had things hunkering down.

Before turning in for the night, I started to hike the short (0.6 mi) Meadow Nature Trail. I’d made it about halfway around when I decided that hiking the trail on a moonless night by myself was not such a bright idea and turned around. I really got spooked on the way back out when I saw two glowing eyes not far away but breathed a sigh of relief when their owner turned out to be a mule deer, who was equally spooked by my approach and bolted, crashing away through the darkness.
Day 7
I normally dislike mornings that we have to break camp and move on—I’d rather relax for an hour or so and enjoy a cup (or two) of French press coffee while catching up on the previous day’s field notes. Today was supposed to be such a day, but I negotiated with Rich to delay our departure until mid-morning to give the grassland tiger beetles (Cicindelidia obsoleta santaclarae) that we saw beginning yesterday’s hike a chance to become active again so I could try for better photographs. The coffee tasted good this morning, and three wild turkeys strutting nonchalantly through our campsite made my leisure hour just that much more enjoyable. Once it warmed up a bit, I went to the corrals where we’d seen them before—nothing! We decided to go ahead and break camp, then go back and check again after we were all packed up—nothing! This was puzzling, since we were there at the time we’d seen them the day before. All I can say is figuring out insects is hard—especially in the West, and if I live to be 100 I don’t think I’ll ever fully figure them out. With that, we said our goodbyes to Dog Canyon—I truly look forward to coming back!

It was a long drive between Eddy Co. and our first collecting spot of the day, and we stupidly made it even longer by going all the way back to Roswell to restock on groceries for the coming week. While we were there, we decided to each lunch at a restaurant instead of out of the car—further adding to our travel time (but the burritos from Burrito Express were so good!). The last leg from Roswell to near Mayhill was—like last time—the worst, with temperatures soaring up to 100°F and the landscape providing so very little of interest.
Carr Canyon Rd Lincoln National Forest Otero County, New Mexico We arrived at about 4:30 pm—still plenty of time to collect and, if we didn’t like what we saw, move on, and we were happy that the higher elevation was providing some temperature relief. We had come to this spot last time based on a prior record of a rather fine buprestid species (Buprestis prospera) from the area, but it was bone dry at the time and we moved on without even getting out of the vehicle. Conditions seemed much better this time, but still I saw no pinyon pine (the larval host) to inspect—and certainly no dead ones to chop into. We were here, however, and decided to give it a shot. I did find a few small dead Juniperus deppeana (alligator juniper), but beating them produced only a single Anomoea sp. (likely an incidental association). The scrub oaks (not sure which Quercus species they represent) as well were leafing out nicely, but sweeping them produced only a smattering of Chrysomelidae (leaf beetles), Elateridae (click beetles), and Curculionidae (weevils)—no Buprestidae (jewel beetles) or Cerambycidae (longhorned beetles). A dry creekbed ran through the area, and I noticed rather lush growth of grassy vegetation in and alongside the creekbed. Recalling that I’d swept such growth along the roadside in nearby Mayhill a few years ago and got a series of Taphrocerus schaefferi, I began sweeping. This was much more productive—each sweeping pass produced one or two Taphrocerus (will need to examine closely to determine if they also represent T. schaefferi, also that is likely), and by the time I finished I had a nice little series of around eight individuals. Checking back with Rich, neither he nor I were seeing much else of interest, so we decided to continue on to the next locality near Cloudcroft.

Switchback Trailhead Lincoln National Forest Otero County, New Mexico The threatening clouds that had just started appearing as we were leaving the previous spot developed into full-blown rain showers as we continued up the mountains to Cloudcroft. Just as quickly as they had come, however, they abated and we arrived to this spot under broken clouds and cool early evening temps. Of all the locations where I had placed traps, my expectations were lowest for this one due to its combination of high elevation (nearly 9000’) and dense, coniferous forests (wine-based baits typically do not attract beetles associated with conifers). I went ahead and placed traps here, however, because 1) I already had several sets at lower elevation woodlands, 2) the presence here of Quercus gambelii (Gambel oak)—a high elevation oak that could be hosting a variety of interesting beetle species, and 3) perhaps the ethanol component of the bait might still attract conifer associates. What I found was completely unexpected—all three traps contained several species of Cerambycidae, none of which I immediately recognized to species! The most abundant species appears to be a large, blonde lepturine, and there was also a smaller Stenocorus sp. as well as a few even smaller species that will require closer examination to identify. I was happy to see all three traps not only still hanging, but also with a little bit of bait still in the bottle and the propylene glycol in the reservoirs not completely dried out. This is in contrast to the traps at all the other lower-elevation localities, which exhibited bone-dry bait bottles and little to no propylene glycol remaining in the reservoir. The thought occurred to me that perhaps the reason these traps were so much more productive was because they remained attractive for the entire one-month period following their placement, while traps at other localities dried up after two or three weeks and failed to attract beetles during the latter part of the period—potentially after beetles had begun to appear in numbers. On the other hand, the very different habitats could also easily explain such a difference. As for the traps, expectedly the SRW/EtOH trap had the largest catch volume, the EtOH-only trap had the smallest (though still good numbers and variety of beetles), and the SRW-only trap volume was in between. Sadly, the white bottle trap was not only pulled out of the ground but completely missing—I can only guess that one of the many hikers that pass through the area saw it and couldn’t resist their inner vandal. The lateness of the hour precluded much further collecting, but I noticed a couple of Anthaxia (Haplanthaxia) caseyi on flowers of Rosa woodsii (Woods’ rose). Based on locality and their dark coloration, they should represent the subspecies A. c. pseudotsugae—unlike the bright green individuals of the nonimate subspecies found further west in California.

There were lots of other plants of various types in bloom, suggesting that a return to this spot with sunny conditions might be warranted. It also convinced me that I should replace the bottle trap here (using the one I retrieved from Mescalero Sands), given the uniqueness of this locality—I’ll just need to find a more secluded spot to place it.
Upper Karr Canyon Campground Lincoln National Forest Otero County, New Mexico During my last visit with Mike, we camped at Lower Karr Canyon Recreation Area on the west side of the mountains below Cloudcroft. It was a nice place to camp but with no table or restroom. This time, Rich and I decided to try Upper Karr Canyon, and boy were we impressed—high elevation (9350’!) with a spacious campground and, most importantly, tables! There were other people in the campground, but everyone was spaced so far apart that it still felt private—at least, until the toddler in the next campsite had a meltdown and woke the infant, who himself then had a meltdown! It was dark by then, so I decided to take a walk to look for night-active critters and hoped that the frazzled parents would manage to get things under control by the time I returned. I saw lots of tenebrionids, of course, but also far more Carabidae (ground beetles) than I typically see out west—perhaps because of the high elevation. Nothing, however, warranted placement in my bottle, so I returned to a (thankfully) quiet campground and admired the amazing starscape in the sky above in the time before the waning gibbous moon began rising in the east.

Day 8
I was tempted to do a bit of collecting before we broke camp—Cicindela purpurea (pasture tiger beetles) were flitting amongst clay exposures in the campground, and Trimerotropis verruculata (crackling forest grasshopper) serenaded us with their snap-crackle-popping flights. We decided instead to break camp anyway and head back to Switchback Trailhead.

Switchback Trailhead Lincoln National Forest Otero County, New Mexico After a quick stop at Mexican Canyon Overlook (I actually made it to the far end of the cantilever lookout deck!), we went back to Switchback Trailhead so we could get a better look than allowed by our quick trap check stop the previous evening. This included examining the variety of flowers and sweeping the large patches of mature Gambel oaks in hopes of finding the recently described Brachys rileyi. I also wanted to reset a new bottle trap to replace the one that was stolen, except this time I hid the trap in an exposed area inside a large patch of Rosa woodsii (Woods’ rose). I barely got the trap set when I noticed more Anthaxia on the flowers and collected a nice series of what I now believe are two species—A. (Haplanthaxia) caseyi pseudotsugae (due to its dark coloration) and A. (Melanthaxia) expansa (due to the two pronotal impressions). I went back to the car to get my long-handled net for sweeping the Gambel oak and found nearby a stand of Ratibida columnifera (Mexican hat) with more Anthaxia plus Acmaeoderavariegata on the flowers. Sweeping the Gamble oak was disappointing—no Buprestidae of any kind, much less B. rileyi, but I did collect a small variety of other beetles including a very tiny adult of what must be Neoclytus irroratus. I was about to go back and see if Rich was having any luck when I spotted a large flowering Sambucus cerulea neomexicana (western elderberry). My long-handled net came in very handy, as I was able to seep the flowers high up out of normal reach. The first tree yielded what I suspect is Agrilaxia arizonae, and after sweeping the four different tree in the area I collected two more adults. I’m not aware of the occurrence of this species east of western New Mexico, so we will have to see how it compares to the very similar species A. texana. The last plant was very close to one of my bait traps (SRW-only bait)—I couldn’t resist the temptation to take a peak and was happy to see a lepturine longhorn already in the trap. It was the smaller, darker species that I thought yesterday was a species of Stenocorus, and a little bit of internet sleuthing revealed it to be the very local and uncommonly collected S. copei—a very nice species that I have never collected before! Now I am even more excited about the trap results from this spot and am anxious to see what they trap in the next couple of months. (I also sleuthed the larger yellow species and believe it is Centrodera spurca [yellow Douglas-fir borer]—not an especially rare species, but one that I have never collected and this population representing one that is interestingly disjunct from the main population in the Pacific Coast states.)

In the meantime, Rich learned from a passing Forest Service worker that a small protected area for the Sacramento Mountains checkerspot butterfly (Euphydryas anicia cloudcrofti), currently proposed for listing on the endangered species list, could be found just up the road. Rich had to promise that we were not interested in collecting the butterflies before the worker agreed to tell him where the caged butterfly food plots were located, so we went up to take a look at them.
Bailey Canyon Rd Lincoln National Forest Otero County, New Mexico While Rich examined the food plots (he did not see either larvae or adults), I examined the flowers alongside the road, collecting more Acmaeodera variegata and Anthaxia spp. of the flowers of Hymenoxys hoopsii (owlsclaws) and Achillea millefolium (common yarrow).

There were several additional flowering Sambucus cerulea neomexicana (western elderberry), but sweeping the flowers produced no additional Agrilaxia. Nothing else sparked our interest, so we then headed to Trestle Depot Recreation Area in nearby Cloudcroft.
Trestle Recreation Area Lincoln National Forest Otero County, New Mexico This little picnic spot caught my eye when I was here last month, looking like it might be good for a quick stop and look around. Musk thistle (Carduus nutans) in flower along the roadside may be an exotic invasive plant, but the flowers attracting a variety of butterflies were of immediate interest to Rich. I looked as well to see if there were any beetles on the flowers, but there were not and so went back to the picnic area. Immediately I spotted a freshly dead Douglas-fir (Pseudotsuga menziesii) and walked toward it. As I approached, I saw two Buprestis lyrata adults on the trunk—one of which flew off as I spotted them and the other I caught. I checked the trunk carefully to see if there were others, and failing to find any I checked out a nearby cut Ponderosa pine (Pinus ponderosa) stump. I suspected, however, that the first one would eventually come back to the tree, and when I returned it was there. It was too high to reach, however, so I found a long dead stick, placed the loop of my net right beneath it, and used the tip of the stick to cause it to drop into the net. I would catch two more adults this way on successive returns to the tree, and while these would be my only specimens from the visit I was quite happy to have found them.

“Point of Sands” Otero County, New Mexico By the time we finished up at Trestle Depot, it was mid-afternoon and I wanted to show Rich “Point of Sands” where White Sands National Monument spills across the park border and down onto Hwy 70. I’ve collected some very nice Buprestidae associated with Ephedra torreyana (Torrey’s joint-fir) on previous visits (Acmaeodera recticollis and Sphaerobothris ulkei), but last month when I visited here with Mike it was bone dry with very little in flight. This time, it was not only bone dry, but also 108°F—seriously! We were here, and I didn’t want to assume that we would find nothing, but for the first 20 minutes it felt like we were walking in an oven. Somehow, I adapted and the heat stopped bothering me, and when I found a male cicada (Diceroprocta eugraphica) singing in an Atriplex canescens (four-wing saltbush) I was motivated to continue looking to see if something else might be out. This was the case, although it was limited to cicadas at the far south end of the stop—a female Hadoa townsendii on the old fruiting stalk of Yucca elata (soaptree yucca), and a female D. eugraphica on A. canescens, both of which cooperated for photos nicely.

Rich had long ago returned to the car to cool off in the air conditioning but then became worried when I went out of view and didn’t return shortly—I’d just started heading back to the car as I saw him coming to look for me! We both decided that we’d had enough of 108°F temperatures and continued on to our next destination, the fantastically beautiful Organ Mountains-Desert Peaks National Monument!
Aguirre Springs Campground Organ Mountains-Desert Peaks National Monument Doña Ana County, New Mexico The ascent up into the Organ Mountains is among the most spectacular of any—tall dried stalks of sotol give the slopes a “brushy” appearance in front of sharp, jagged peaks.

The campground itself is also gorgeous; however, beauty is one thing—the presence of insect activity is another, and the parched-looking, still-quite-warm landscape (though nothing like the oven that we encountered at the previous stop) had us wondering if it would even be worth staying one night, much less the two that we had planned. I suggested spending a little bit of time beating the local vegetation—if I found beetles we would stay, but if not (as I fully expected), we would go back to Upper Karr Canyon to enjoy another night at its high, deliciously cool elevation and then head north in the morning to search for “greener pastures.”
View from our campsite in Aguirre Springs Campground.
I got out the beating sheet and whacked the branch of a nearby hackberry, and to my surprise onto the sheet fell an Agrilus sp. (in fact, I was so surprised that I’d neglected to ready my aspirator and the damn thing got away!). More whacks of the hackberry produced nothing, so I regarded it as a fluke and turned my attention to the gray oaks (Quercus grisea). With one whack, onto the sheet dropped two Sternidius decorus—a species I know only from Arizona, and with continued beating I collected an additional individual or two at regular intervals.
Okay, so it looked like things might be happening here—despite the very dry-looking conditions, and we went about setting up camp. Dusk settled in as we finished our dinner, and I set up not only the ultraviolet lights but also the mercury vapor lamp. To make things interesting, I also set out a prionic acid lure near the lights in case there were any Prionus beetles in the area. It didn’t take long for the first male to show up—a remarkably small P. heroicus, and over the next hour several additional, more normal-sized males showed up.

The lights alone also began attracting Cerambycidae as soon as full darkness arrived—many individuals of Methia mormona showed up, but so did other species such as Hypexilis sp. and what I take to be a species of Elaphidiini.

Additional cerambycid individuals arrived regularly, and we would have left the lights up longer had occasional gusts and distant lightning not become blustering winds and certain rain. We got the lights taken down and put away with little time to spare, then spent the rest of the night not sleeping while high winds buffeted and heavy rain pelted the tent. (Its a good thing I got a new tent last year—my old one would not have survived!)
Day 9
La Cueva Recreation Area Organ Mountains-Desert Peaks National Monument Doña Ana County, New Mexico Given the heat we experienced yesterday, we decided to do any lower elevation collecting first thing in the morning and then come back up into the mountains for the afternoon when (hopefully) the higher elevations would provide some relief. Some good species of Buprestidae have been taken by others in the vicinity of La Cueva picnic area on the other side of the mountain range, so we headed down there to take a look.
Backlit, backside peaks!
It was already hot by mid-morning as we headed out on the Arroyo Trail. Conditions were dry, but the mesquites (Prosopis glandulosa) had fresh foliage and the whitethorn acacias (Vachellia constricta) even had flowers. Hackberries (Celtis reticulata) were thick along the trail, and large oaks (Q. grisea and Q. turbinella) dotted the arroyo margins. Beating, however, produced nothing—no Buprestidae, no Cerambycidae, not even Chrysomelidae. I didn’t feel like continuing to “beat” a dead horse, especially when temperatures were skyrocketing and the mountains were beckoning, so we cut bait and headed back up the slopes.
La Cueva Recreation Area.
Pine Tree Loop Organ Mountains-Desert Peaks National Monument Doña Ana County, New Mexico The Pine Tree Loop is purported to be a 4-mile loop with 1000 ft of ascent (all within the first two miles!). My main objective was the small leafmining buprestid Brachys rileyi, which is known only from higher elevations in New Mexico and west Texas on Gambel oak (Quercus gambelii), and it was found a few years ago along this very trail. This was not my first attempt to find the species here—I stopped by two years ago guided by that record, which had been placed on the popular citizen scientist platform iNaturalist. Unfortunately, the record was inaccurately placed at a lower elevation (below the Gambel oak zone). I (incorrectly) assumed that the host must have been misidentified and that the species had been collected instead on gray oak (it is not unusual for buprestids thought to be associated with one host to eventually be found on another) and was rather frustrated to later learn that the inaccurate placement was intentional—the beetle had been photographed after it was collected, and because the true location had (amazingly!) not been recorded, the record was instead placed at a random point somewhere near the start of the hike. I must have beaten every oak within 100 feet of that (erroneous) location—obviously without success! I have since found other examples of such “malplacements” on iNaturalist, a practice which I can only describe as sloppy at best, and I implore all iNaturalist users (especially practicing entomologists) to record the most accurate placements for observations of insects photographed later as collected specimens rather than as live individuals out in the field. Obviously, this will involve more detailed note-taking; however, accuracy is, after all, a basic tenet of science! [Now climbing down from my soapbox.]
Greeting at the beginning of the Pine Tree Loop Trail.
Okay, so now knowing that the record actually came from the Gambel oak zone on the upper part of the trail, we readied ourselves to hike the trail in its entirety. The scenery grew increasingly spectacular as we ascended, during which time I beat selected trees—mostly Quercus grisea (gray oak), from which I got a lone Acmaeodera quadrivittatoides on the lower slopes and a couple of Polycesta arizonica—represented in my collection until now by just a couple of specimens collected many years ago in west Texas—from a bit further up.

At long last, we reached the Gambel oak zone and I began beating stands near the trail in earnest. Almost immediately I add another Sternidius decorus to the series I’d gotten the previous evening, giving me hope that further beating would bring success. After only a few more minutes, a Brachys landed upside-down on my sheet! I quickly picked it up and popped it into the vial, then turned the vial until I could see the upper side. I was looking for the blue coloration with red apices to confirm its identity as B. rileyi, but instead its uniform coppery color indicated it was B. querci. Until a couple of years ago when I collected a good series of this species in the Davis Mountains of west Texas, I would have been very excited by this capture. Instead, my momentary elation turned to disappointment. Still having collected one species of Brachys gave me hope that I would still find the other, but that would not be the case—continued beating of Gambel oak was fruitless, and even my ability to do that was cut short when a popup thunderstorm moved in and drenched everything (including us!). I will admit that we welcomed the break in temperatures, as the heat and effort from the ascent had by then begun to take its toll on us, but eventually the rain moved out (creating some spectacular views as it moved across the slopes below us), and I resumed my beating.

For a long time nothing hit my beating sheet (except a shower of water drops, which I had to continually shake off the sheet). Just before we passed back out of the Gambel oak zone after beginning our descent, I got a sort of consolation prize—a large(-ish) sp., and as I was putting the beetle in the vial a Prionus heroicus male flew by and circled slowly back towards me to within net’s reach. Not long after, as I was beating the last of the Gambel oaks that we would see, Rich called out to me from further down on the trail saying he saw another Prionus crawling on the ground and that it had crawled under a dead log. We lifted the log (gray oak), and there she sat—the most enormous gravid female P. heroicus I’d ever seen! I wanted a photo, but she started running so I blocked her with my finger to get her to stay still. This did not work despite repeated attempts, and at one point when I became rather careless with my finger placement she gave me the most painful beetle bite I’ve ever had—bringing blood right on the most sensitive part of my fingertip! I guess giving me a good nip brought her some satisfaction, because after that she stayed put long enough for me to snap the photos I wanted. By this point, we were really feeling the combination of miles, heat, thirst, and hunger and focused on completing the rest of the descent back to the parking area, where we enjoyed a (very) late lunch and cold liquids under a table with shade!

Aguirre Springs Campground Organ Mountains-Desert Peaks National Monument Doña Ana County, New Mexico When we got back to the campground, I was so drained that all I wanted to do was rest (and continue rehydrating!). But, I still had the set of jug traps (that I’d taken down from Mescalero Sands) and had decided that the juniper/oak woodland around the campground with large gray oaks could be an interesting place to set them. We’d seen very few people in the area since our arrival (apparently camping in the heat of the summer is not popular here!), but I still wanted to eliminate any chance of the traps being molested so hoofed it past the barbed-wire fence on the west side and bushwhacked across the slope to a line of large gray oaks on the other side of the ravine. The SRW-only trap was placed furthest up the slope, the SRW/EtOH trap in the ravine, and the EtOH-only trap above the ravine nearest the road. On the way back to the campsite, another P. heroicus male flew within net’s reach, which I nabbed and gave to Rich. I also watched a large, orange/black female velvet ant (family Mutillidae) crawling on the ground and soon noticed a male that must have been the same species (smaller but identical coloration) fly in, circle around, and land on the ground not far from the female. I hoped he would encounter her, but when he was within a couple of feet he suddenly took flight and disappeared—perhaps she didn’t smell right or, in fact, was not a conspecific!

Spotty showers and gusty breezes prevented another night of lighting, but honestly we were both so exhausted from the day that we welcomed the opportunity to relax after dinner and catch up on our field notes.
Day 10
We enjoyed a much more restful night than previously thanks to cooler temperatures and awoke to spectacular views over the valley below. It was hard to think about turning around and heading back to the north and east, but both of us had committed to returning to St. Louis by late Friday—if we were going to keep that commitment we would have to make significant progress today. Our plan was to go back to Black Mesa in the extreme northwestern corner of Oklahoma (where we had been rained out at the beginning of the trip). At about a 7½-hour drive, we would have plenty of time to collect in the area before facing Friday’s 12-hour slog back to St. Louis. I did get a “goodbye gift” before we left—another Polycesta arizonica that was sitting on the tent as we broke camp!

Pajarito Rest Stop Roosevelt County, New Mexico At the halfway point of the drive—approaching Tucumcari in east-central New Mexico, we decided to stop at an interstate rest stop for lunch and were pleased to find sheltered picnic tables to enjoy our meal. Afterwards, while exploring the grounds a bit (never pass up an opportunity to look for bugs!), I spotted a lidless white cooler sitting next to the fence along the back edge of the area. I don’t know what I expected to see inside of it, but when I looked I saw standing water in the bottom… and beetles! It was nothing more than a giant bowl trap! We brought the cooler back to the car, poured the contents through a sieve and rinsed before dumping out, and picked out a cerambycid (Strangalia sexnotata), two scarabs (Euphoria kernii), and a few other miscellaneous beetles (but, unfortunately, no Acmaeodera).
“Cooler trap” at Pajarito Rest Area.
Kenton Cimarron County, New Mexico As we continued northward through northeastern New Mexico, we noticed what looked like rainclouds in the distance, and checking the radar forecast showed spot thundershowers moving through the area around Black Mesa. All we could say was “Here we go again!” and spent the remaining few hours of the drive watching the clouds and constantly checking the radar updates trying to predict if rain would actually occur at our planned collecting spot—a sandstone outcropping with juniper/oak/pinyon woodland just east of the tiny town of Kenton. Rain seemed certain as we passed through Clayton—about 30 minutes south and west of Kenton—when we got drenched while making a quick pit stop, but as we neared our destination the clouds started breaking up a bit, even allowing occasional peaks of sunlight. We arrived at the spot at either 5 pm or 6 pm, depending on whether we followed Central or Mountain Time (the time zone boundary passes right through the area), and though it had rained, it was neither cool nor overly wet. I had discovered Prionus heroicus in this area a number of years ago (with the help of prionic acid lures), and given our repeated sightings of this species the previous two days, I set out lures to see if they were active in this area. Almost immediately the males started flying in, easily recognized from afar by their enormous size, peculiar waving of their hind legs while flying, and diesel engine-like sound of their flight!

I collected a few to document the occurrence, but what I was most interested in doing here was beating the oaks. There are two species here, Quercus × undulata (wavylweaf oak) being the more abundant and Q. mohriana (Mohr oak) represented by sporadic individuals. I had beaten a nice series of Brachys barberi (and one B. aeruginosus) from the former last month and collected a few cerambycid-pruned branches from the latter, but beating on this day produced little. I did, however, note several additional cerambycid-pruned branches on the very same Q. mohriana from which I had collected them last month, which I bundled for rearing, and beating the living branches produced a single Chrysobothris purpureovittata purpureovittata.

Also from Q. mohriana, I beat a large, impress caterpillar that I soon decided must be one of the Hemileuca spp. (sheep and buck moths—family Saturniidae). The only species known from the area is H. oliviae (range sheep moth), but it clearly did not look match images of that species, so Rich decided to see if he could rear the caterpillar to adulthood and collected foliage from the tree to provide additional food until it pupated. [Edit: The host, location, and gestalt (especially the reddish dorsal coloration between the segments) suggest it is Hemileuca grotei diana (Grote’s buck moth). Apparently this species has not yet recorded from Oklahoma, but the location in far northwest corner is very close to several Colorado records, and the species also occurs in Texas, New Mexico, and Arizona. Rich also wrote the following update on his attempts to rear the caterpillar to adulthood:
The caterpillar made it home safely. I put the caterpillar in a large jar with cactus soil, and some of the oak leaves I collected off the bush where it was collected. For the next three days, it fed on the leaves at night and left lots of frass behind. During the day, it remained motionless on the dirt. Since last night, the caterpillar has not moved which could mean that it has died or is parasitized. It may also be taking its time to form a pupa. This is what I am hoping for.]

I continued beating the oaks but found only a few weevils on Q. × undulata before turning back to look around the flats around the parking area. Along the way, I noted a lone Celtis reticulata (net-veined hackberry) along the roadside, from which I beat a single Agrilus. Its chunky size and coppery color had me fooled until I realized it was a stray A. sapindi—normally associated with Sapindus saponaria ssp. drummondii (western soapberry). I’m not aware of the occurrence of soapberry at this particular spot, but it is common at nearby Black Mesa State Park and likely also occurs in other closer areas.

Checking the flats around the parking area, I found not only Moneilema armatum on Cylindropuntia imbricata (cholla), but also Cacama valvata (common cactus dodger).

After taking photos of the latter, I noticed a large beetle crawling on the ground and realized it was a female P. heroicus—only the second female of this species I’ve seen (the first being only one day earlier at Organ Mountains-Desert Peaks National Monument). This brings me to an idea I have about attraction to pheromones in Prionus beetles—released by females (none of which fly to my knowledge) to attract males (which are powerful fliers). The use of prionic acid pheromone lures has greatly facilitated the collection of male Prionus beetles (all species of Prionus appear to be attracted to prionic acid); however, I have also collected females of several species (P. arenarius, P. fissicornis, P. integer, and—now—P. heroicus) while using prionic acid lures to collect male Prionus. In each case, I found the females walking on the ground in the general direction of the lures, suggesting to me that they may be “cheaters”—i.e., rather than producing and releasing their own pheromone, they detect pheromone being released by another female and walk towards the source in hopes of “stealing” a male. If this is true, the energetic cost of producing/releasing pheromone must be sufficiently high to allow cheaters to persist in the population. In today’s case as well, the female was walking in the general direction of the lure from a distance of about 60 meters. It would be interesting to test this hypothesis experimentally (but it will be up to someone else to do this). On the way back to the car, I collected one more M. armatum—this one on Opuntia phaeacantha (brown-spined pricklypear cactus).

Rich came back to the car about the same time, so I checked in with him to see how he had done. He gave me an Acmaeodera (prob. A. mixta/immaculata) that he’d collected on the flower of Pediomelum tenuiflorum (slimflower scurfpea) and wanted to walk back down the gravel road to check for other flowers. I accompanied him, beating oaks along the way without success (but seeing a very impressive Climaciella brunnea—brown wasp mantidfly) until, finally, a B. barberi from Q. mohriana near the bottom of the hill landed on my sheet.

By then it was getting close to dusk, but I hadn’t yet checked the dead Pinus edulis (Colorado pinyon pine) from which I’d beaten two new state records (Oeme rigida deserta and Haplidus testaceus) on my visit here last month. I was keen to see what else might be on the tree a month later and, amazingly, got two more new state records this time as well: Buprestis laeviventris beaten from a branch, and a dead Monochamus clamator clamator (spotted pine sawyer) female stuck on the trunk.

These would be the last insects that I would collect on the trip, and what a final duo they were! On the way back to the car, I picked up a couple of cerambycid-pruned branches of Q. × undulata that I had set aside earlier for rearing. It will be interesting to see if it is the same species that is pruning the two oak species (Q. × undulata and Q. mohriana). With dusk approaching and us still needing to get to the state park and setup camp, we decided that three hours of collecting at the final spot was a good way to close out 10 straight days of collecting!
Black Mesa State Park Cimarron County, New Mexico Our “favorite” campsite in the park was unavailable—in fact, the entire West Canyon campground was closed due to installation of a new dump station for the nearby RV campground. As an alternative, we secured a spot at the nearby Lake Etling Campground. I’ve never stayed there because there are no toilets, but the sites are much larger and come with shelters over the picnic tables—something that would have come in handy during my several previous visits with rain. Site #24, in particular—located at the far end of the campground, nestled up against a low cliff, and well out of sight from the rest of the campground, may well now be my new favorite campsite at the park.
Charcoal “fireworks”!
After enjoying a celebratory rib-eye steak dinner, I walked the roads hoping to see night-active beetles. Unfortunately, the same rains that killed the possibility of setting up the lights also apparently kept the beetles holed up, and I saw nothing. It occurred to me then that this was my tenth visit to the park in the past three years, and it has rained on six of those visits! So much for western Oklahoma being a “dry” place!
A final campfire!
Day 11
The drive from Black Mesa to St. Louis was predictably boring and unfulfilling. Normally I would eschew interstates and divided highways in favor of backroads, but at 12 hours even on the quickest route I had to bite the bullet. At least we did not have to get out of the car while the hottest temperatures of the trip (111°F!) settled over us, and the memories of the trip will feed my souls for a long time to come.
The highest temperature of the trip—111°F! Thankfully, this occurred during the drive home!
As long-time readers will know, I have used “bucket traps” with fermenting liquid bait for many years to collect Cerambycidae. In fact, I discovered my first new species (Purpuricenus paraxillaris) soon after I began using these traps back in the mid-1980s. The traps are simple—a bucket (2-L in my case) filled to about 1/3 with diluted molasses/beer (MB) or sweet red wine (SRW). When placed in the field, the bait ferments, releasing ethanol and other volatiles that attract a variety of longhorned beetles (as well as some other groups of beetles and insects). Beetles attracted to the trap drown in the bait and are retrieved by pouring the bait through a kitchen strainer. The bait, thus, acts as both an attractant and a killing agent. Other collectors of Cerambycidae have used these traps as well for many years, and in fact Marlin Rice and I have just completed a manuscript on a 4-year study comparing the efficacy and relative attractiveness of bucket traps baited with MB vs. SRW in Missouri, Iowa, and Florida—look for that paper to appear (hopefully) later this year in The Coleopterists Bulletin.
More recently, however, I have switched from bucket traps to “jug traps.” These differ obviously in that they are jugs with “windows” cut into them rather than open-top buckets. More importantly, however, instead of fermenting bait, the bottom of the jug (i.e., “reservoir”) is filled with dilute propylene glycol. Like fermenting liquid bait, propylene glycol forms a trap from which the beetles cannot escape, but it plays no role in attracting the beetles to the trap. Instead, it acts as a preservative to prevent deterioration of the trapped beetles after even prolonged submersion. Attraction to the trap is still accomplished with bait, but in this case it is isolated inside a bottle that is suspended inside the jug above the reservoir. A wick inserted into the bait and extending above the top of the bottle enables the release of ethanol and other volatiles from the bait to serve to attract beetles to the trap. A variety of baits can be used—I have been comparing the relative efficacy of three: pure ethanol, sweet red wine, and a 50:50 mixture of the two (look for a manuscript on the results after this season).
The advantages of jug traps are several-fold. First, beetles trapped in propylene glycol do not deteriorate (beetles trapped in fermenting bucket traps will deteriorate if not removed within about a week). Second, wicked bottles of ethanol-based baits last much longer (several weeks) than fermenting liquid baits in open buckets (10–12 days). These features drastically reduce the frequency with which traps must be serviced, allowing placement of traps at much more distant locations and enabling sampling of more distinct faunas. In all the years that I used bucket traps (1984–2021), the vast majority were restricted to east-central Missouri (within about an hour’s drive from my home). On the other hand, in the past three years of using jug traps, I have been able to place them across southern Missouri (2022), the Oklahoma panhandle (last year), and throughout eastern New Mexico (this year)!
I mentioned above my plans to publish the results of my first three seasons using these traps and comparing relative efficacy of the different baits (in fact Marlin Rice and I will be combining again to publish data collected not only in Missouri, Oklahoma, and New Mexico, but also Iowa and south Texas). Each time I’ve mentioned using these traps, however, I’ve received questions about how to make and deploy them. This will, of course, be fully detailed in the eventual publication, but since “a picture is with a thousand words,” I’m posting some of the details with photographs here to allow folks to begin using them without waiting for my published paper.
Trap construction
Almost any plastic jug will do, but a minimum size of 1-G is suggested. The finished jug shown below is from the cheapest drinking water I could find (99¢ per gallon). I will note that these jugs are made of low density polyethylene (LDPE), and after a couple of seasons of use in the field, those that were exposed to full sun eventually became brittle and cracked. For this reason, I’ve been replacing them with jugs made of high density polyethylene (HDPE) (of which you will have plenty after purchasing ethanol and propylene glycol!). Either way, I used a utility knife to cut a “window” into each side of the jug. The windows should be large enough to allow free access to the jug interior, but take care to keep the bottom edges of the windows high enough above the bottom of the jug to accommodate at least one liter of propylene glycol in the reservoir. You may also notice two additional modifications that I made: 1) the presence of a nylon cord loop at the top of the jug (allows the trap to be hung in the field), and 2) a metal S-hook inserted into the cap (allows hanging of the bait bottle inside the trap). The cord loop is simple—a 6-inch length of nylon cord threaded through two holes drilled below the mouth of the jug and tied to form a loop. The S-hook hanger installation is described further below.
Modified 1-G jug ready for use as a trap.
I used 250-ml water bottles for the bait bottles, which, in the conditions I’ve experienced, is enough bait to last 4–5 weeks. I will be trying larger (500-ml) bottles this season to see if they will last longer (hoping for two months). I drilled a hole into the center of the bottle cap that was large enough to accommodate a 5.9-inch long by 0.3-inch wide cotton humidifier stick. The stick acts as a wick that provides a continuous releases of ethanol and other volatiles from the bait. I also fashioned a hanger for the bottle using an ~10-inch length of plastic-coated copper wire (it’s what I had sitting around) to suspend the bottle inside the trap.
Modified 8-oz water bottle. A stiff cotton stick is inserted through a hole in the cap, and a wire hanger is added.
To suspend the bait bottle inside the trap, I installed an S-hook in the cap of the jug by drilling two small holes in the cap and threading the S-hook through them. If you make the holes slightly closer together and squeeze the S-hook with pliers while threading, the S-hook will end up being held more securely in the cap with little likelihood of popping out.

Deploying the trap
In the field, find a suitable spot to deploy the trap. The “perfect” spot will depend upon the habitat, but I always look for a tree in relatively open (i.e., accessible) habitat with an unobstructed branch around 8–12 feet above the ground. Tie a rock or heavy stick to one end of a long nylon rope and throw it over the branch. Tie the other end of the rope to a carabiner, which is then clipped to the cord loop at the top of the trap. Hoist the trap to eye-level and keep it in place by tying the cord to a nearby trunk or branch. Fill a bait bottle with your choice of bait (right now, the 50:50 mixture of ethanol and wine seems to be the most effective) and hang it from the S-hook inside the trap (see photo below). I also like to give the bottle a twist or two so the wire wraps around the S-hook, securing the bait bottle and reducing the likelihood it will be dislodged by high winds. The photo shows a red plastic plate above the trap to act as a rain shield; however, I have found this unnecessary and no longer use them.

Once the bait bottle is in place, fill the jug reservoir with 50:50 diluted propylene glycol. I have been using about 750–1000 ml per trap, which usually is enough to last for about a month. Areas with low humidity, high temperatures, or heavy beetle populations may require a higher volume to last that long, so adjust accordingly.
A carabiner is used to hang the assemble trap from a nylon chord strung over a tree branch.
Once the bait bottle is in place and the reservoir filled, hoist the trap up until there is about a foot of rope between the branch and the trap (closer makes the trap more vulnerable to spillage from high winds and also provides easier access for “raiding” by raccoons). Secure the rope again to keep the trap in its fully hoisted position, then stand back and admire your handiwork!

Servicing the trap
You can check the traps at any time, but as mentioned the advantage of this trap is its ability to not only attract beetles, but preserve them over an extended period of time so that remote or difficult to access habitats can be sampled. Servicing the trap is similar to servicing bucket traps in that the reservoir contents are poured over a kitchen strainer placed on top of another bucket to catch the liquid. The liquid can be reused and the volume topped off, but I like to replace it completely if it has become diluted due to rain or discolored due to large numbers of insects attracted to the trap.

If the catch is not overwhelming, it can be sorted in the field, but in many cases the number of insects—not just the target beetles (in my case, Cerambycidae), but other beetles (especially Elateridae and cetoniine scarabs) and even other insects (e.g., noctuid moths, flies, wasps, etc.) can be so high that it is easier to simply transfer the entire catch to a ziplock bag (1-qt bags are usually sufficiently large, but if the trap catch is overwhelming a 1-G bag may be necessary) and sort the catch at a more convenient time and place. Either way, I start out by overdrenching with water to rinse the specimens and then pick out the target specimens. If the catch is large, it is easier to spread it out on a white fiberglass or plastic tray and add water to help separate the specimens. In this case, I drop the specimens that I pick out into paper toweling to blot off the excess.
Cleaned, sorted beetles ready for processing.
Once the target specimens are segregated from the bycatch, I place them in glass vials and add a few drops of ethyl acetate to tissue in the vial (for larger quantities, I use plastic specimen cups and a few ml of ethyl acetate) to prevent spoilage until the specimens can be further processed at a later date. Further processing involves washing the specimens to remove remaining traces of propylene glycol and other contaminants. This is done by soaking the specimens overnight in soapy water, rinsing thoroughly, and then blotting the specimens dry on paper towels before returning them to storage as above or pinning them directly. Unlike specimens trapped in fermenting MB or SRW baits, specimens trapped in propylene glycol tend to be stiff, which makes arranging the legs and antennae during pinning more of a challenge. I have found that prolonging the wash soak before pinning helps to soften the specimens—the longer the better (even specimens soaked for two months did not deteriorate). Apparently the initial period of submersion in propylene glycol provides some preservative benefit.

As with any new trap, the potential for optimization is great. I’ve mentioned some of the optimizations that I have tried or am currently trying such as the bait itself. Other potential improvements include the size of the bait bottle and the amount of propylene glycol used in the reservoir to allow trap placement for even longer periods of time before it needs to be serviced; the type of wine used—perhaps one with the highest possible sugar content to prolong or increase the intensity of fermentation; and a more secure method of hanging/attaching the bait bottle inside the trap (zip ties?). I’m sure a readership as erudite as mine will be able to come up with any number of other possible improvements, both to the trap itself and to the methods I’ve outlined for deploying the traps and processing the catch.

Welcome to the 14th “Collecting Trip iReport” covering an 11-day insect collecting trip to eastern New Mexico on May 14–25, 2024. Joining me (again!) for the trip was Mike Arduser, melittologist-extraordinaire with whom I’ve collected on and off for nearly 40 years! This is actually the first of two planned trips to New Mexico this summer—not only to collect, but also to set (on the first trip) and pick up (on the second) “jug” and “bottle” traps placed at several locations. Thus, this will be the third (and final!) season of data collection for a jug trap study that I have been conducting for the past two years (2022 across southern Missouri and 2023 in the Oklahoma panhandle). For this season, my plan was to collect and set traps up and down the eastern half of New Mexico (which seems to have been largely ignored by insect collectors and, thus, could yield some interesting records). As with the previous two seasons, placing and retrieving traps provides an opportunity to see distant habitats at multiple times during the season, thereby increasing the opportunity to see different things. It can also help “make up” for bad weather or off-timing during one of the visits. On this trip, we ended up making 16 visits to 13 different localities (12 in New Mexico, three in Oklahoma, and one in Kansas). I also placed traps at six of the localities in New Mexico in habitats ranging from low elevation sandhill scrub to mid-elevation pinyon/oak/juniper woodland to high elevation alpine forest. I’ll return to New Mexico in late June to pick up the traps—hopefully within the 5-week period that they will have been out they will attract a nice variety of interesting beetle species.
Yesterday was a largely uneventful 12-hour drive from St. Louis to Black Mesa State Park in the northwestern corner of the Oklahoma panhandle.

Day 2
vic. Kenton Cimarron County, Oklahoma I’ve grown to love this spot over the past few years, and it seems to be the perfect starting point for an insect collecting trip into the western U.S. While my goal is to hang “jug” traps throughout eastern New Mexico as part of my trapping study, we had to stop at this spot just east of Kenton, a favorite because of the sandstone escarpment featuring pinyon/oak/juniper woodland—typical of further west but very unusual for Oklahoma—and the correspondingly unusual insects that we have been finding here. Spring seems to have just arrived here, as some greening has taken place and most of the deciduous trees have leafed out. However, the soapberry is just beginning to leaf out and the oaks not quite finished, so definitely on the early side of the season. Right off the bat after getting out of the car I found Moneilema annulatum (ambulated cactus beetle) on Opuntia phaeacantha (brown-spined pricklypear cactus), but from then on it was pretty slim pickings for a good while as I waited for temperatures to warm slowly through the 60s up towards 70.
As I headed towards the woodland atop the sandstone outcrop, I noted Melampodium leucanthum in bloom but saw no Acmaeodera on the flowers. I beat the oaks and pines for a bit, seeing only chrysomelid leaf beetles on the former until I came upon a dead Pinus edulis (Colorado pinyon pine) and beat Oeme rigida deserta and Haplidus testaceus—both I believe to be new state records for Oklahoma—as well as a small acanthocinine cerambycid (all singletons) from the branches.
Oeme rigida deserta (family Cerambycidae) beaten from branch of dead Pinus edulis (Colorado pinyon pine).
Haplidus testaceus (family Cerambycidae) beaten from branch of dead Pinus edulis (Colorado pinyon pine).
At the bottom of the outcropping I finally beat one Brachys sp. (prob. barberi) from Quercus x undulatus (wavyleaf oak)—finally I have found this species in Oklahoma! I continued to beat the heck out of the oaks and collected a variety of mostly cryptocephaline and chlasmisine leaf beetles but never did see another Brachys. In the plain below the outcropping I collected another M. annulatum on O. phaeacantha. Sphaeralcea coccinea (scarlet globemallow) was also abloom in the plain near and along the gravel road, and in the flower of one of the first plants I looked at I found a single Agrilus sp. (prob. malvastri). Frustratingly, no more were seen in the many flowers that I looked at afterwards. Xanthisma spinulosa (golden golden spineweed) was also blooming along the gravel road, and for awhile I only saw and picked up a couple of meloids, but finally I saw one Acmaeodera sp. on one of the flowers. This individual looks very much like the eastern A. tubulus, which would be an extraordinarily western occurrence for the species! Meeting back up with Mike back at the parking area, we discussed our respective successes and looked around a little bit more. These final efforts resulted in another Moneilema—this one M. appressum—on O. phaeacantha. Mike also gave me a meloid he collected from the flower of Oenothera lavandulifolia (lavenderleaf sundrops).
Mills Rim Campground Harding County, New Mexico After a quick ice stop in Kenton, we headed towards Mills Rim in northeastern New Mexico. I’ve been to this canyon-edge where the toe slopes of the Rocky Mountains drop down to the western edge of the Great Plains proper. Temps were nice and skies sunny when we left, but after entering New Mexico we kept our eye on a large thundercloud in the distance that seemed to be right where we were going. The closer we got, the more it seemed that was the case, and as we entered the grassland it was raining hard with plummeting temps. It eventually blew through, but alternating periods of light rain with cold winds and calm conditions with patchy sun ensued. I took the opportunity while conditions were iffy to place the first set of jug traps for the trip around the rim of the canyon, and on the way back I placed a white bottle trap in the rock plain where I’d had such good luck last July collecting Acmaeodera.
Mills Rim looking towards Mills Canyon.
By the time I returned to the car, conditions had improved to the point that we decided to continue to look around and see if any insects might be active. I found a patch of Sphaeralcea coccinea (scarlet globemallow) and searched the flowers and foliage hoping to find Agrilus malvastri. All I found instead were a few bees, which I gave to Mike. (Ironically, these would be the only bees that Mike would leave with from the visit!)
Echinocereus coccineus coccineus (scarlet hedgehog cactus—family Cactaceae) in pinyon/oak/juniper woodland.
I had spotted a freshly dead Pinus edulis (Colorado pinyon pine) along the campground road (off which I also collected a few longhorned beetles last year) and headed over to start beating it. Right off the bat I got an Anthaxia sp. (something in the subgenus Melanthaxia, but who knows what it is?!), and continued beating produced another Haplidus testaceus (not a new state record for New Mexico) and a clerid (Enoclerus sp.).
Scathophaga stercoraria (golden dung fly—family Scathophagidae) in pinyon/oak/juniper woodland.
I then started beating the oaks (Quercus x undulata—wavyleaf oak) and at first got only cryptocephaline leaf beetles, but quickly I got another Anthaxia sp.—this one in the subgenus Haplanthaxia (I can’t think of an oak-associated species that might be out here)—followed quickly by not one but two Brachys sp. prob. barberi! That provided plenty of motivation to continue beating the oaks, and I did so for another couple of hours, alternately dodging rain drops, having my arm nearly torn off by wind gusts, and getting some respite during brief sunny periods. I did collect a few more Haplanthaxia during that time as well as a variety of cryptocephalines, but no more Brachys.
Dalea formosa (feather dalea—family Fabaceae) in pinyon/oak/juniper woodland.
Eventually, hunger and the need to set up camp forced me back to the campsite, where we enjoyed bourbon salmon cooked in our trademark “dirty skillet”. After dinner and the ensuing darkness, I went out to walk the roads to see if anything might be out and about. I didn’t expect to see anything—and didn’t, but I also wanted to check out the dead pinyon pines and found two more H. testaceus on one nearer the canyon.

Day 3
The forecast for the day was not good—scattered thunderstorms and very cool temperatures. This was true not only for Mill Canyon, but anywhere else in New Mexico for that matter. That being the case, instead of remaining here in not ideal conditions, we decided to make ground to the south while we had the chance. Perhaps on the way back we can revisit Mill Canyon—likely the rains and a week of sun and warm temperatures will do a lot to move things along. We drove through a spectacular canyon south of Mill Canyon—all apparently private land, unfortunately—but eventually ended up in driving rain for most of the way to Roswell (though not before we were able to check out a fascinating abandoned homestead).
Abandoned homestead in Newkirk, New Mexico.
We had intended to check out Bosque Redondo Park along the Pecos River near Fort Sumner, but heavy rain forced us to cancel that idea. After passing through Roswell, we checked out Bottomless Lake State Park just east of town in the Pecos River valley as a possible place to camp, then continued on to Mescalero Dunes (and checking out an even more fascinating abandoned homestead!).

10 mi W Caprock Chaves County, New Mexico There had been a break in the clouds while we were at the park, but as we approached the dunes we drove back into heavy clouds, light drizzle, and cold winds. We debated whether to camp there that night and then decided to defer our decision until after I placed a set of jug traps in the soapberry stands along the highway in the north side of the recreation area.

On the way back to the car I found a Batyle suturalis (sutured longhorned beetle) hunkered down on the flower of Hymenopappus flavescens (collegeflower)—the first insect of the day (and what I thought would be the last of the day!). Back at the car, we decided that it was simply too cold and windy to camp here and that it would be (somewhat) more comfortable at Bottomless Lakes where it was a little bit warmer and probably better protected from the wind. That would turn out to be an incredibly fortunate decision!

Bottomless Lakes State Park Chaves County, New Mexico We picked out a nice, relatively isolated campsite bordering a rocky gypsum/red siltstone slope and immediately started exploring. There were a few plants in bloom, and almost right away I found an Acmaeodera mixta on the flower of Thelesperma magnicamporum (rayless threadleaf). I would eventually collect a few more on the same a bit further up the slope and also on the flower of Prosopis glandulosa (honey mesquite).

Mike also found a large Eleodeslongicollis doing its classic headstand. Further up the slope we started finding buprestids on the mesquites—without the aid of a beating sheet! The beetles were torpid because of the cool temps (and possibly also the late hour) and we easily picked off the plants by hand. I collected another A. mixta but was more excited to find several Acmaeoderopsis hulli and then very excited to find first a male and then a female of Chrysobothris humilis—a strikingly sexually dichromatic species that I had never collected!

A few Agrilus sp. and other Chrysobothris spp. were also collected, along with Plionoma suturalis and Aethecerinus latecinctus—the former not uncommon and the latter not rare but always nice to find.

With a little over an hour left before sunset, we decided we’d best get dinner cooked (burgers!) and the tent set up, and afterwards I went back up onto the slope with my beating sheet and collected nice series of the buprestids and cerambycids I’d collected earlier (but no more C. humilis, unfortunately). I also picked up a few darkling beetles, including another E. longicollis.

However, the prize of the night was when I found an Amblycheila picolominii (plateau giant tiger beetle) crawling on the slopes—a species I do not have in my collection! I kept my eye out hoping to see more and did not, but who knows what tomorrow will bring?

Day 4
This location was not originally in our sights as a possible collecting locality, and our original plan was to return to Mescalero Sands and spend the day collecting there. However, we were so surprised by the diversity we saw last evening after our late arrival at this spot that we decided to spend at least the morning here instead and then regroup around lunch to decide what we wanted to do. This being the case, it was nice to be able to relax a bit after breakfast while catching up on our field notes instead of breaking down camp and moving on.
One of the many “cenotes” (water-filled collapsed underground cavern) along the base of the slope along the east side of the park.
Things started off good almost immediately! I found a single clump of Senna roemeriana (two-leaved senna) across the road from the campsite, from which I beat Acmaeodera pubiventris lanata—seems like an unusually eastern occurrence for the species! After making my way to the Bluff trail, I started beating Prosopis glandulosa (honey mesquite) around the vicinity of the trailhead and collected several Chrysobothris spp. (likely C. octocola and C. lateralis) and more Aethecerinus latecinctus along with a few clytrine leaf beetles.

The fun really started, however, when I started taking a closer look at the stems of living Atriplex canescens (fourwing saltbush). I remembered cutting Amannus vittatus from such near El Paso, Texas a couple of years ago and, thus, knew what to look for—emergence holes on not-too-small, still-living stems. I found such almost immediately when I began looking closely inside the plants, and on the very first stem that I decided to break open I found not only a larva in its gallery but a teneral, unemerged adult! I broke open more stems and found a few more larvae, so I went back to the car to retrieve a saw, where I encountered Mike and us both agreeing that we should just spend the rest of the day here. Hiking back to the saltbushes, I cut the stems in which I’d found larvae, along with several more that seemed like they might be right for infestation, and bundled them up to bring back for rearing.

It was then past noon and I’d had made it no further than the vicinity of the trailhead; progress was further delayed when I got back on the trail and encountered a stand of Thelesperma magnicamporum (rayless greenthread) in bloom. I looked at the flowers hoping to find some interesting Acmaeodera spp., but all I found were a few A. mixta and Trichodes orestes. The name of the trail led me to believe it would go up on top of the bluff, where I thought the habitat might be more interesting than the mesquite/saltbush chaparral that I was following, so I continued further. That never happened, so I began bushwhacking the slope where I found the occasional Opuntia macrocentra (black-spined pricklypear cactus) in bloom. Pricklypears flowers are normally Acmaeodera magnets, so I inspected each blossom that I encountered carefully but found only a single A. mixta for the effort.
By then curiosity was getting the better of me and I just had to see where the trail actually went. The mesquite/saltbush chaparral gave way to more of a tamarisk wasteland, and I began to suffer a bit from heat and thirst as I carefully metered my water bag, but at o e point along the trail I encountered a patch of yellow asters in flower that remain undetermined (they key to Senecio flaccidus in “Flora Neomexicana” but are precluded from that species by their succulent, linear, undissected leaves). Edit: these were determined by George Yatskievych at the University of Texas in Austin to be Pseudoclappia arenaria, or Trans-Pecos false clapdaisy). I monitored the patch for a while but collected only a small series of A. mixta from its flowers.

The trail, disappointingly, terminated not in some interesting blufftop habitat, but at the RV campground on the south end of the park, so I turned around and made the long, hot, thirsty slog back to the tent campground where I chugged a bottle of sport drink and scarfed down a can of sardines on crackers (a favorite field lunch!). Mike had done exceedingly well collecting bees near the campsite on a variety of flowers and in bowl traps that he’d set on the lower slope behind the campsite. He also gave me the few buprestids that had been attracted to the latter, most being the common A. mixta but also a female Chrysobothris humilis, bringing to three my series of this fine, uncommonly encountered species!
On our first trip into the park to look at the campground, I spotted the alkaline shore of “Lazy Lagoon.” I thought there must be tiger beetles there, so after a bit of rest and rehydration I went back to the lake and hiked down to the shore to see what cool tiger beetles I would find.

I stalked and scanned and searched and surveyed, but nary a tiger beetle was to be seen! If I hadn’t found Amblycheila picolominii the previous night, I would have begun to wonder if I was losing my tiger beetle mojo.

I ended up walking the entire perimeter of the southmost lakebed and saw few insects at all except Erynephala puncticollis (beet leaf beetle—family Chrysomelidae) feeding on the fleshy, succulent foliage of Allenrolfea occidentalis (iodine bush), so I headed back to the campsite to process the day’s catch and work on my field notes.

After a dinner of bison steaks, I had considered setting up the lights to attract nocuturnal insects, but my motivation was dampened by the strenuous day and waxing, now first quarter moon. I was also more interested in walking the rocky gypsum/red siltstone slope behind our campsite to see if I could find more Amblycheila picolominii to go with the one I found the previous night and beating the Prosopis glandulosa (honey mesquite) in hopes of finding more individuals of Chrysobothris humilis to go with the three I had. Beating the mesquite was productive, but only for Chrysobothris octocola and C. lateralis—no C. humilis were seen, nor were any of the other buprestids I’d seen the previous night such as Acmaeoderopsis hulli or Agrilus spp. I also struck out with A. picolominii, finding only a single small tenebrionid (darkling beetle) crawling over the rocks. The nighttime views, however, were spectacular—with the moonlit slope behind the campsite, the stars featuring a prominent Big Dipper, and the hauntingly beautiful flowers of Anulocaulis leiosolenus (southwestern ringstem—family Nyctaginaceae), being the standout memories!

Day 5
Mescalero Sands Recreation Area Chaves County, New Mexico We were happy to be leaving the area this morning and heading to Mescalero Sands, as the day’s forecast was even hotter than the previous day and the slightly higher elevation at the dunes would help to mitigate some of that heat. We arrived at the dunes mid-morning, and almost immediately I noticed dung beetles flying low to the ground. The culprit was freshly deposited droppings from a dog, and while most of the beetles flying around and tumbling over the pieces were Canthon sp., I did pick up a female Phanaeus vindex.

One of my priority species for the locality was Agrilus hespenheidei, which I have collected only sparingly during previous visits; however, I also hoped to see other species associated with the stands of Quercus havardii (shinnery oak) that dot the sand dunes and surrounding areas here such as Brachys barberi and Chrysobothris mescalero. Sweeping the oak immediately turned up both species, and continued sweeping a few C. purpureovittatus and a nice series of a very tiny Agrilus sp. (possibly something I’ve not collected before) along with a few Cyrtolobus sp. (treehoppers) and some very tiny Enoclerus sp. (checkered beetle). In between sweepings of the oak patches, I saw several small dung beetles (possibly Boreocanthon sp.) rolling rodent scats, one Aethecerinus latecinctus a small meloid in flight, and a much larger meloid—Lytta reticulata—perched on the underside of a leaf on Phacelia integrifolia.

Hiking north out of the dunes into the chaparral I encountered the first of several Prosopis glandulosa (honey mesquite), off which I beat one Plionoma suturalis along with another small meloid and tiny clerid, but further beating of mesquite was not productive and I turned my attention to other things. One was a lone, fading flower on Oenothera albicaulis (most other plants of this species seemed to be finished blooming, off which I took a single Acmaeodera quadrivittatoides, and a bit further to the north I started encountering Hymenopappus flavescens (collegeflower) in bloom, almost all that I looked at hosting one or two resting Batyle suturalis. Though I was now well north of the dunes, patches of Q. havardii still dotted the area, and sweeping them produced not only more C. mescalero as expected, but also several Acmaeoderopsis hulli and another A. quadrivittatoides. The former especially was a bit of a surprise to me, as I have collected that species exclusively on mesquite; however, in checking the Nelson catalogue I see that oak has been reported as a larval host for the species. From that point on I focused on finding flowers which might be hosting Acmaeodera or longhorned beetles and encountered Lorandersonia pulchella (southwestern rabbitbrush) hosting several B. suturalis on its flowers.

Xanthisma spinulosum (golden spinyweed), usually a good at attracting Acmaeodera, were sparse, but I did find a few hosting A. quadrivittatoides, and along the roadside I found a few Psilostrophe tagetina (woolly paperflower) blooming, with one or two A. mixta on the flowers. The floral host prize, however, went to the lone pricklypear cactus that I found in bloom—Opuntia macrorhiza (prairie pricklypear cactus), which was literally overwhelmed with A. mixta and especially A. quadrivittatoides.

By this time I was hot and tired and thirsty and started heading back towards the car, collecting a few A. mixta and B. suturalis on the flowers of Thelesperma magnicamporum (green threadleaf). I met up with Mike back at the car—he himself had also collected a nice diversity of bees off the flowers in the area, and we decided we’d seen what we needed to and that we’d head south to Eddy Co. for the next day’s collecting. On the way out of the area, I stopped inside the entrance and set a white bottle trap near the pay station.
Our next insect collecting destination was the southernmost tract of the Lincoln National Forest, where I suspected species more typical of west Texas may be found. Along the way, we decided to check out the campground at Bentley Lake State Park—we were extremely unimpressed and decided to drive to Dog Canyon Campground in Guadeloupe National Park just over the Texas state line.

We were taking a chance—drop-in camping at a National Park on a Saturday night is generally unsuccessful, but the season was still early and we managed to snag the last site available in the tent loop. The three-quarters moon was spectacular as it rose above the massive cliffs across the canyon, and the cool night air was a welcome change from the blistering 100°F that we experienced most of the day at lower elevations.

Day 6
In the morning we broke camp and headed back into New Mexico to a spot where the Davis Mountains specialty Purpuricenus opacus was recently taken, expanding its known range to beyond the confines of west Texas. Before we had gone very far, however, we had to save a prairie rattlesnake (Crotalus viridis) that we saw stretched out across the road. Of course, we had to stop and gawk at it and take photos. He was none too happy with us, quickly assuming a ready-to-strike pose and rattling persistently as I approached from various angles to photograph it (from a safe distance).

After finishing, we had little faith that the next person that came along would be as snake friendly as us, so we decided to move him off the road. We couldn’t find a stick long enough with which to push it and still keep a safe distance, so we got my telescoping insect net, extended it all the way out, and pushed him gently with the net bag. Of course, instead of “running” away from the net, he struck at it several times and then crawled inside it! We then carried it in the net to well away from the road and laid the net out along the ground so that it eventually found its way out. Now that it was on a natural surface, I needed more pics, to which he took just as much offense as he did during the previous photo session. We decided to name him “Ryan the Rattlesnake,” and he was probably very happy to see us leave.
The rattlesnake was no less angry after being placed on a more natural substrate!
“Hamm Vista” Klondike Gap Rd EddyCounty, New Mexico After saving Private Ryan, we arrived shortly at this locality southwest of Queen. Like we had seen driving in yesterday, the area was bone dry—apparently none of the rains that rolled through New Mexico earlier in the week had touched this mountain range. As a result, there was no fresh foliage on the oaks to beat nor flowers from which to pick insects. Despite this, I was motivated to hang a set of jug traps in the hope that rain would eventually hit the area and trigger emergence. Should such be the case, having traps hung in the area would be my best chance of trapping P. opacus. I hung the traps in a roughly equilateral triangle centered on the road pull-off and set a white bottle as well for good measure. With no insects actually seen, however, we decided to cut bait and move on.

“Wooded draw” XBar Rd Eddy County, New Mexico As we were driving, I mentioned to Mike that I’d like to hang one more set of traps in the area, and that an ideal spot would be around 5000’ elevation and still in the oak zone—preferably a wooded draw that crossed the road so I could hike up into and place the traps. As we approached the 5000’ mark east of Queen, we saw just such a draw off to the east, and almost immediately afterwards we came to a road that turned off the highway towards the draw. We took it, and about ½ mile down we found a pull out right next to the draw, which was filled with oaks! Amazingly, the elevation where we parked was exactly 5000’—talk about fate! It was as bone dry as the last spot, but again I hung the traps anyway—all three in the ravine with a white bottle trap near the parking area just above the draw.

As I was setting traps, I found a couple of Opuntia camanchica (tulip pricklypear cactus) in bloom, one of which was drawing lots of Acmaeodera. Most appeared to be A. quadrivittatoides (although I must now be on the lookout for a lookalike new species that we found in west Texas a couple of years ago); however, one seems to be the recently described A. natlovei, and another seems to be A. gillespiensis—a west Texas specialty that I’m not sure has been reported from New Mexico. Upon returning to the car, Mike gave me a vial of Acmaeodera that he had collected from bowl traps that he’d set out—again, most appeared to be A. quadrivittatoides but with at least one A. natlovei and one A. gillespiensis. Thus, despite the dry conditions I walked away with a few good finds.

Switchback Trailhead Otero County, New Mexico It was a frustrating drive from Eddy Co.—temperatures through the low elevations soared up to 100°F, and the landscape provided little of interest. As we climbed in elevation, however, the temperatures began to decrease, and as we entered the national forest I was happy to see pines and oaks beginning to replace mesquite. Our first locality after entering the national forest, however, was a bust—conditions were still bone dry, and with nothing but pines and junipers on which to collect there was no point in even trying. Perhaps on my next trip back here in late June there will be a reason to stop and look for conifer-associated buprestids. We decided to continue on towards Cloudcroft, but before we did we stopped at a gas station in Mayhill for ice. As I was approaching the front door, I found a Zopherus concolor sitting on the sidewalk—freshly dead but intact and apparently having crawled there sometime during the previous evening before expiring. One of the best gas stations finds I’ve ever had!
Shortly afterwards we arrived in Cloudcroft, where I had two localities I wanted to check out. One was Trestle Depot Recreation Area, and the other was Switchback Trail. We went to to former first but were unimpressed by the closed coniferous forest with only small patches of small Gambel’s oaks. The trailhead area for Switchback Trail was much more interesting—a large open expanse with a variety of flowers and many large patches of mature Gambel’s oaks.

The latter was my primary interest, as I believe the recently described Brachys rileyi—collected on Gambel’s oak at several high mountain locations in southeastern New Mexico and west Texas—should also occur here. The leaves, however, were just beginning to expand—a consequence of the +8000’ elevations, so I considered it unlikely that Brachys would yet be out. I used the telescoping tropics net to sweep the high branch tips anyway, and while I did not find B. rileyi, I did collect a series of alticine leaf beetles that, curiously, resemble B. rileyi in their size and coloration—metallic blue with a narrowed reddish “apex.” In the case of these beetles, however, the narrowed reddish apex is the head and pronotum, while in B. rileyi it is the elytral apex. Satisfied that further sweeping would not yield any buprestids, I set about hanging the jug traps—again in a roughly equilateral triangle along the edges of the forest with a white bottle trap in the open area near the parking area.

With evening approaching, we wrapped up the collecting and headed to Lower Karr Canyon, where we enjoyed “dirty burgers” for dinner and a very pleasant night of sleep (elevation 7830’—it got quite cold!).
“Dirty” burgers!
Day 7
“Point of Sands” Vista Eddy County, New Mexico After breaking camp, but before heading to other locations further north, we made a quick detour to this cool place where White Sands National Monument spills across the park border and down onto Hwy 70. Three years ago when Jeff Huether first took me to this spot, I found a carcass of Sphaerobothris ulkei, which likely breeds in the Ephedra torreyana (Torrey’s jointfir) growing here. I brought Jason Hansen, Joshua Basham, and Tyler Hedlund here the following year hoping to find Sphaerobothris—we did not, but we did find Acmaeodera recticollis, another species associated with Ephedra and one which I had not collected before. I was hoping to find either/or this time, but the dry conditions made it clear from the start that it was unlikely.
Scanning the dunes for signs of insects.
We walked the area anyway—down the E side of the highway and back up the W (sand dune) side where we parked. It wasn’t until I reached the sand dune that I saw anything of note—a few bees in the flowers of Thelosperma megapotamicum (rayless threadleaf), which I collected for Mike. I half expected an agent or two from the Border Patrol station up the road to pay us a visit (which happened to me last time I stopped here), but no such visit occurred. No longer desiring to beat a dead horse, we decided to travel back north to the Lincoln National Forest and see if some localities even further north might be more productive.
Paradise State Park Union County, New Mexico The localities further north in the Lincoln National Forest around Ruidosa were just as bone dry as further south. We actually stopped and got out of the car at Grindstone Lake, but the combination of high elevation with no deciduous trees, lack of plants in flower, and crowds of people choking the trails caused us to get right back in the car. An hour’s drive to another small mountain range to the east was equally disappointing, with the same dry conditions and the campground unexpectedly closed to overnight camping! At that point, we decided we needed to bite the bullet and blast as far east as we could, where we knew rains had soaked the area the previous week, and decided on Oasis State Park as a place that might offer the combination of moist conditions, interesting habitat, and ability to camp that we desired. The shift from brown, dusty dry to verdant green across the landscape once we got east of Roswell was sudden and striking, and the landscape remained green the rest of the way to the park, which appears to be a northern extension of the same sand dune system that is found further south in Mescalero Sands and still further south near Kermit, Texas. We were quite hopeful as we found a campsite and got out of the car to start exploring. There was a nice variety of dune-type plants in bloom, including pricklypear cactus—always a favorite of mine for hunting jewel beetles in the genus Acmaeodera.
Opuntia camanchica (tulip pricklypear cactus—family Cactaceae) in sand prairie.
Sadly, there seemed to be very little insect activity going on—perhaps a result of our relatively late hour of arrival (6 pm). I checked the pricklypears in the prairie near the campsite for a while, but after not seeing insects in the flowers I decided to walk the Sand Dune Trail. There wasn’t nearly as much pricklypear in the dunes as in the area near the campsite, but I checked them anyway. On the back end of the trail I finally found a buprestid beetle—Acmaeodera mixta bedded down inside a curled petal on the flower of Helianthus annuus.

Shortly afterwards I found an Eleodes hispilabris (clown beetle) crossing the sandy trail—as soon as he saw me he assumed the classic “headstand” defensive pose and allowed me to take a pic.

Nothing else was happening (although Mike did get a small variety of bees off the various blooms), so we setup camp and cooked “dirty bratwursts”!

After dinner, I went to check out the restroom lights, as they were nice and bright (not the “yellow” anti-bug lights that most parks use!). Unfortunately, there were no beetles to speak of, but there were a few moths and a very large, very cool Hogna carolinensis (Carolina wolf spider—family Lycosidae) that actually “hopped” to escape my molestations and eventually ended up in a great pose for photos.

Day 8
“Caprock Amphitheater” Quay County, New Mexico We spent the morning catching up on our field notes before breaking camp. No new insect activity was showing up by the time we were packed up, so rather than spend more time here we decided to head back up to Mills Canyon where we had started the trip last week. The landscape north of Portales is stunningly featureless, so imagine our surprise when we happened upon a spectacular escarpment that dropped precipitously as we approached San Jon just east of Tucumcari. Unlike the unendingly treeless plains above and below, the escarpment itself was covered with pinyon/oak/juniper woodland. Mike and I had the same idea at the same time—find a place to pull over and give the place a look!
“Caprock Amphitheater.”
Right off the bat I found Acmaeodera mixta on the flowers of Thelosperma magnicamporum (rayless greenthread), but further inspection of various “Acmaeodera flowers” (e.g., Opuntia and Melampodium) was fruitless. Beating oaks was fruitless as well, so I went back to examining flowers.
Opuntia camanchica (tulip pricklypear cactus—family Cactaceae) in pinyon/oak/juniper woodland.
After about half and hour to 45 minutes, activity seemed to pick up—I started seeing Acmaeodera ligulata on the flowers of both Melampodium leucanthum (blackfoot daisy) and Opuntia camanchica (tulip pricklypear), and over the next hour or so I continued to add to the series and found a few A. quadrivittatoides on each as well.

I also resumed beating and picked up a few misc. insects before finally beating a single Brachys barberi from the branch of Quercus x undulata (wavyleaf oak). I beat a lot more oak after that but never found another Brachys, then turned my attention to Prosopis glandulosa (honey mesquite). The very first branch I whacked yielded a large Chrysobothris merkelii, but afterwards all of my beating produced only a few other misc. insects. The area around the pulloff was limited in area by steep cliffs on one side and the road on the other, so I crossed the road where Mike was already monitoring flowers. I did collect more A. ligulata on the flowers of Senecio flaccidus (threadleaf ragwort), but the hillside was steep, difficult to traverse, and yielded only more A. ligulata on M. leucanthum.

Feeling like I’d gotten a good sampling of what was out, I decided that this would also be a good spot to hang a set of traps, as it was far removed from any of the other sets of traps that I’d hung in the state. I hiked up the road to the top of the canyon (finding a single A. ligulata on the flower of Erigeron sp. along the way), hung a trap from a tree in the drainage, hiked back down to the parking pulloff to hang another trap, then crossed the highway and hiked down about 1/8 mile to the top of the slope to hang the third trap.

When I returned to the car, Mike was picking up his bowl traps (in which he’d also collected several Acmaeodera spp.). Considering that a melittologist thought it was a good spot to place bowl traps to attract flower-visiting bees, I decided it should also be a good spot for placing a bottle trap to attract flower-visiting Acmaeodera. By the time I had all my traps in place, we’d spent about four hours at the spot—an unexpected end to our frustrating (and literal) dry spell!
Mills Rim Campground Harding County, New Mexico Fresh from success at the previous spot, and seeing how green the landscape had become as we continued further north, we were filled with optimism about what we might find at Mills Rim after rains had soaked the area a week ago a d sunny skies had warmed the landscape since. The landscape also had become much more interesting than further south, as hints of canyonlands appeared with greater frequency (with the occasional abandoned homestead still dotting the landscape).

The final ascent through a spectacular canyon south of our destination back up onto the plateau let us know our drive was almost done. We stopped at a pile of freshly-cut juniper just inside the boundary of the Grassland, expecting the branches to be crawling with longhorned beetles in the genera Callidium/Semanotus or jewel beetles in the genus Chrysobothris, but alas none were seen. Still, we arrived at the campground (unfortunately, our favorite site was occupied, so we had to settle for the neighboring site) full of optimism about what we might see in the day that was left. My first target was a stand of Sphaeralcea coccinea (scarlet globemallow) near the campsite, from the flowers of which I hoped to find Agrilus malvastri. I did eventually find one, but only after looking at a lot of plants and seeing only leaf beetles and other misc. insects.

I then returned to the dead Pinus edulis from the branches of which I’d beaten both buprestids and cerambycids the previous time but this time beat only one Acanthocinus sp. and a few other misc. insects. Likewise with Quercus x undulatus (wavyleaf oak)—I’d beaten some (not a lot) of nice buprestids from their branches during the previous week’s visit, but this time only a few misc. other insects were found.

Mike fared little better, seeing very few bees on the flowers (in fact, the bees I collected on S. coccinea formed the bulk of his collections from this visit). We debated about whether it was too early in the season or too late in the day, but in my opinion the area still had the feel of “early” (I took a peek inside one of the jug traps that I’d hung last week and, other than moths, saw only a single beetle—Euphoria fulgida). I suspect it will be still later in May or even early June before insect activity really starts to pick up at the site.

Nevertheless, it was an enjoyable visit (as always), and a special treat was the Texas horned lizard (a.k.a. “horny toad”, Phrynosoma cornutum) that visited the campsite and entertained us while dining on harvester ants. While it may have been on the early side for insects during this visit, I will be returning in mid-June, during which time insect activity should be in full swing!

After dark, I returned to the dead P. edulis after dark and found a single Zopherus concolor on the ground at the base of the trunk (I found several of these on the trunks of dead P. edulis last year at this same location).

Day 9
The lack of insect activity continued during the morning, and with forecast temperatures not even reaching 70°F, it became clear that waiting would not change anything. We had considered continuing north to Sugarite State Park very near the Colorado state line. However, the forecast there was no better—in fact, cool temperatures were forecast across northeastern New Mexico, and only in areas further east did the forecasts look more promising. Rather than beat a dead horse and try to collect in New Mexico anyway, we decided to head back to one of our favorite spots in Oklahoma—the sandstone outcropping near Kenton that we visited at the start of the trip (and from which I have already found so many great records over the past few years). We could then camp at Black Mesa State Park, drive to Gloss Mountain State Park the following day, and camp at nearby Alabaster Caverns State Park for the final night of camping before heading home in Friday. I kept an eye out for someplace to set my last set of traps (I’d brought seven sets), but all we saw before entering Oklahoma were smiling dinosaurs!
Dinosaurs are everywhere in this part of the country!
He’s smiling!
nr. Kenton Cimarron County, Oklahoma Temperatures were already well above 70°F by the time we arrived, and the sunny skies further increased my optimism. I started out checking the flowers of Xanthisma spinosa (spiny goldenweed) along the gravel road behind the outcropping but saw only a few blister beetles & bees (the latter I collected for Mike). Thelosperma megapotamicum (rayless slenderthread) was also in bloom, from which I collected Trichodes oresterus.

What I was really after, however, was Brachys after beating a single specimen (prob. B. barberi) from Quercus x undulata (wavyleaf oak) last week. It didn’t take long before I found one, and it didn’t take long after that to find another one. Over the next hour or so, I accumulated a nice series of about a dozen specimens by working the oaks in an expanding zone around the tree from which I’d collected the first specimen. In addition, I also collected a very small Brachys that looks like B. aeruginosus—if that’s what it is, then it is a very unusual far western record for the species—and a variety of other misc. beetles (mostly cryptocephaline and chlamisine leaf beetles). While I was beating the oaks, I found Opuntia polyacantha in flower (the only such plant I saw all day) and collected a small bee (for Mike) & misc. beetle from its flower.

After beating all the oaks along the gravel road, I went up on top of the outcropping to continue beating the oaks situated above those I’d been beating along the gravel road, which ultimately added a few more specimens to my series of Brachys. Before doing that, however, I went over to a small area where I had seen Melampodium leucanthum (blackfoot daisy) in bloom the previous week to see if they were by now attracting Acmaeodera. Only a few were seen, all at first representing only A. quadrivittatoides (which I first collected here as a new state record in 2022), but when I returned a short while later I found a couple more plus one A. ligulata, which I believe itself to be a new state record! Returning to the oaks, I noticed some “flagged” branches on one of the Quercusmohriana (Mohr oak). This seems to be an unusual northern outpost for the species, which is more commonly found throughout much of Texas, and pulling the branches off the plant revealed cerambycid-pruned larval galleries inside, prompting me to gather and bundle the branches for rearing.

As I worked my way east along the outcropping, I encountered some small, recently (and apparently deliberately) cut branches of Pinus edulis (Colorado pinyon pine), and inspecting the branches revealed a couple of small Chrysobothris that must be C. cuprescens. By this time, I was near the dead P. edulis tree from which I’d beaten a few longhorned beetles the previous week (including two potential new state records!). I did not beat any beetles off of its branches this time, but I did collect one of the branches for rearing. By this time, I’d been out for more than three hours and was getting hot, thirsty, and hungry, so I headed back to the car to check in with Mike. Collecting had been a bit slower for him, though still productive, and he gave me a few Acmaeodera—two A. mixta and one A. ligulata—that he’d collected on the flowers of M. leucanthum across the highway, along with three clytrine leaf beetles that he’d collected on flowers of Eriogonum sp. I went over to the Melampodium spot to see if I could find more Acmaeodera (I did not, as it was starting to get late in the day), but what I did find might be one of the coolest finds of the trip—a perfectly complete, perfectly clean, wholly intact skull amongst the skeletal remains of a gray fox (Urocyon cinereoargenteus)—a truly spectacular find!

Black Mesa State Park Cimarron County, Oklahoma Our usual campsite was taken, so we had to “settled for the neighboring site. After setting up camp; however (and seeing the neighbor’s tent flapping noisily in the wind), we decided that our smaller but more sheltered and private site was actually even more desirable!
Full moon (almost) rising!
We cooked the last of the meat—“dirty” burgers, and after darkness had settled I went out to hunt the roads and trails to see what might be out and about. Immediately upon hitting the road, I found Eleodes longicollis lumbering across the pavement and goaded it into a headstand for photos.

Nothing else, however, was seen during the entire rest of the walk (other than the “pet” dinosaur outside the campground supply store).

The nearly full moon, however, was a sight to behold, especially in this area which is known for its darkest of night skies!

Day 10
Gloss Mountain State Park Major County, Oklahoma Early last week as we made our way out to Black Mesa State Park at the beginning of the trip, it felt really strange to pass right by Gloss Mountain State Park without even stopping. It has been among my favorite collecting localities over the past 15 years, and nearly every collecting trip I’ve made to northwestern Oklahoma since I “discovered” this spot in 2009 has started here. Cool weather in New Mexico, however, chased us back east a few days earlier than we had planned, and we both welcomed the sudden opportunity to collect at a time of year (late May) that neither of us have been here before.
Return to Gloss Mountain!
Mike immediately found a stand of Astragalus (milkvetch) below the front slopes that were pulling in bees and stationed himself there. I knew exactly where I wanted to go—a small woody copse of Celtis reticulata (net-veined hackberry) and Sapindus saponaria var. drummondii (western soapberry) where in previous years I’ve collected great species such as Paratyndaris prosopis (on hackberry) and Agrilus limpiae (on soapberry). I had started up the trail on the slope face when I noticed an all-black Euphoria sp. (flower scarab) on the flower of Tamarix ramosissimus (saltcedar) near the trail. I thought at first that it was a species I’d never seen before, but some quick online sleuthing revealed that it was merely a color variant of the common E. kernii (Kern’s flower scarab). A little more searching in a neighboring plant also produced a few of its dreadfully common congener, E. sepulcralis (dark flower scarab).

The distraction over and puzzle solved, I continued up the slope, stopping at a few patches of Mimosa nuttallii (Nuttall’s sensitive-briar) along the way to pick a few Typocerus octonotatus (eight-spotted flower longhorn) and Trichiotinus texanus (Texas flower scarab) from its flowers. About halfway up the slope is another copse of hackberry and soapberry, and beating branches of the former produced numerous Chrysobothris purpureovittata (some unusually coppery-colored, and few the bright blue and green that is typical of the species), one C. caddo, several Agrilus lecontei celticola, several A. paracelti, and one A. obolinus? along with a few other misc. beetles. I’ll need to follow up on the A. obolinus—that is a species I’ve collected only once before (in west Texas). There was also one dead hackberry tree in the copse, from the branches of which I beat a few additional A. lecontei celticola and A. paracelti.
Winds were incredibly strong out of the south, and they actually helped push me up the last bit of the slope and onto the top of the mesa, where I met my old friend again—Parvindela celeripes (swift tiger beetle, formerly Cylindera celeripes)—on the clay exposures between the areas of vegetation. It had been many years since I’d seen this species, which I first found occurring abundantly in the gypsum/red clay landscape across this part of the state back in 2009–2010. I believe this is the earliest date that I’ve seen adults of the species active, which I’ve more normally recorded during June and early July.
Turning my attention to the copse on top of the mesa, I began beating the hackberry and, for a while, collected some the same species I’d collected on the slope below—C. purpureovittata, A. lecontei celticola, A. paracelti—along with a few misc. beetles. Finally, on a hackberry on the backside of the copse, I found what I was looking for—Paratyndaris prosopis! This single individual is the first I’ve seen since I collected about a dozen specimens in the exact same spot back in 2013! I also beat the soapberries in the copse, and unlike the trees on the lower slopes which produced nothing, the trees in the copse produced a nice series of Agrilus egeniformis (normally associated with honey locust but also utilizing western soapberry, thus, giving it an unusual distribution) and a few A. ornatulus. I had hoped to also find A. limpiae (a small series of which I collected here last year during mid-May) or A. sapindi (which I’ve never collected here) as well, but no such luck. I continued further around the perimeter of mesa beating the few hackberries that dot the edge but found only a few more C. purpureovittatus, A. lectontei celticola, and A. paracelti but no more P. prosopis. The wind didn’t make things easy, but I only lost a few of the specimens I’d beaten to the wind (one, however, being only the only other C. caddo that I found during the day). Hiking back towards the edge of the mesa, the winds continued unabated, making it the most difficult descent over the mesa rim and down onto the slope that I’d ever experienced—trying to hold onto my net and beating sheet with one hand while grabbing the rail with the other required a level of acrobatism that I’ve lacked for many years now! Eventually, however, I did make it down off the slope. By then, it was almost evening, and we celebrate the final day of collecting with dinner at a restaurant in Woodward before continuing on to our campsite at Alabaster Caverns.
Alabaster Caverns State Park Woodward County, Oklahoma We both enjoyed fish (and beer!) at Longshots Bar & Grill in Woodward (the last time we tried to have dinner here in May 2022, the kitchen caught fire after we placed our order and we had to find another restaurant. At least they didn’t charge us for the beer!). We got to our campsite with enough daylight left after setting up camp to allow a little beating of the trees around the camp. I beat a couple of leaf beetles from the branch of a Quercus macrocarpa (burr oak—probably planted) and a few Agrilus paracelti from the partially dead branches of a nearby Celtis occidentalis (common hackberry). Further beating of the healthier hackberries in the campground yielded nothing, so we settled down for the evening, reminisced about the past two weeks, and contemplated tomorrow’s long drive home.

Day 11
Gypsum Hills Scenic Byway Information Kiosk Barber County, Kansas The final day of a long field trip is always a mixture of sadness and satisfaction—sadness that the fun is over, but satisfaction with the memories. We talked about some of the more memorable events of the trip and made plans for follow up on ideas discussed, but also looked forward to getting back home and resuming our normal lives (after a bit of rest!). We weren’t quite done with the collecting, however—I knew of this spot in south-central Kansas (sort of on the way home) where a beautiful tiger beetle species has been taken during the spring: Cicindela pulchra. Its common name is, in fact, beautiful tiger beetle, which is a direct translation of its scientific name! I haven’t seen this species in many years (since 2011 in the Black Hills of South Dakota!), so I wanted to take the opportunity as it presented itself. Arriving at the spot with sunny skies and temps above 70°F seemed promising, but it became clear fairly quickly that the tiger beetles I was after were not active at this site at this time. There were, however, flowers in bloom, and I collected a few other things from them (though nothing special). These included Batyle suturalis (sutured flower longhorn) on Thelosperma magnicamporum (rayless greenthread) and Typocerus octonotatus (eight-spotted flower longhorn), Euphoria kernii (Kern’s flower scarab), and a few more bees on Mimosa nuttallii (Nuttall’s sensitive-briar) and Callirhoe involucrata (winecups). I was really hoping to find Agrilus muticus on the latter plant, as I’ve only collected a few specimens of this species, and that was many years ago.

Eventually, we knew it was time to go—there was no more “one more stop,” and we settled into a beautiful drive across the southern edge of Kansas before the final drive up through familiar terrain across the Missouri Ozarks!
p.s. “Little Bits” (my little black kitty cat 🐈⬛) was sure glad to see me!
It’s my birthday, and as I’ve done almost every year of my adult life I did my first “real” collecting trip of the season. Since we’re down in Florida visiting Madam’s sister, I was especially excited for the chance to see new ground and hopefully find a few Florida specialties. The day started by getting up early to watch a spectacular full-moonset over the ocean—something I’ve never seen before.

Touchdown!
I then headed up to the Citrus Wildlife Management Area of Withlacoochee State Forest to hook up with fellow beetle enthusiast (and soon-to-be book chapter coauthor) Kyle Schnepp from the Florida State Collection of Arthropods. Although Kyle and I have previously met at society meetings, it was our first time in the field together, and I was keen to take advantage of his local expertise to help me in my quest for Florida-endemic species. The habitat was dry oak/pine sandhill woodland with a grassy understory dotted with Opuntia australis (Florida pricklypear cactus)—itself an endemic plant.
Opuntia australis (Florida pricklypear cactus).
Temperatures were comfortably cool starting out due to an overnight cold front (who knew there was such a thing in Florida?), and I was filled with anticipation as I arrived at the meeting point and prepared my gear and greeted Kyle and his two companions shortly afterwards. I’d hoped to encounter Brachys leafminers, and we beat the oaks, both Quercus laevis (turkey oak) and Q. geminata (sand oak), exhaustively in search of such, but none were found. At one point, I pulled out the telescoping tropics net to see if I would have better luck accessing the upper canopy, but I had no better luck. Through it all, however, I did get a few other miscellaneous beetles and treehoppers on the former and the same on the latter along with an Anthaxia sp. Kyle also collected a Mastogenius sp. on the latter, which I hoped to encounter as well but never did, while his companions encountered single specimens of Agrilus rubroniger (a very nice find—I have but a single specimen that I collected in southwestern Missouri) and Chrysobothris chrysoela. I continued to beat the oaks but increasingly turned my attention to other things, including the pricklypears. The flowers were closed at first (due either to the morning hour or cool temperatures), but peeling back the petals I encountered a mating pair of Trichiotinus rufobrunneus (Florida flower scarab)—a Florida specialty!—plus one of the smaller, more widespread Trichiotinus lunulatus.

I pulled the petals back on a few other flowers but didn’t see anything, then encountered a fallen dead branch of Pinus clausa (sand pine). Carefully lifting and turning over the branch revealed a Chrysobothris cribraria on the branch underside—just the second buprestid of the day for me. I then ran into Kyle again, who mentioned he’d seen a Mecas sp. on a grass stem, so I began sweeping the more open areas where the grasses—still mostly last season’s dried growth—and found two in my very first pass. These proved to be the largely endemic Mecasfemoralis! I would continue to sweep grasses as I traversed the open areas of the woodland, eventually collecting a nice series of 12–15 specimens. As I was sweeping, I noticed isolated plants of the endemic Lupinis ocalensis (Ocala lupine) and, on the foliage of one, a mating pair of lixine weevils that proved to be the endemic Scaphomorphus subcylindricus.

I continued to the south side of the road where I’d earlier seen the pricklypears in hopes of finding the flowers now open. Such was the case, and in addition to further specimens of T. rufobrunneus I also encountered Acmaeodera ornata and Strangalia strigosa—the latter yet another Florida specialty that I’d not previously encountered.
Strangalia strigosa (family Cerambycidae).
Additional sweeping not only increased my series of M. femoralis but also turned up a mating pair of Typocerus zebra (zebra flower longhorn), while Kyle encountered a single Lycochoriolaus lateralis—apparently a mimic of lycid beetles, distasteful to predators, and yet another species I’d never encountered before. After nearly five hours, I decided to call it a day and started working my way back to the car. Along the way, I encountered a patch of Serenoa repens (saw palmetto) in flower. There was quite a bit of insect activity buzzing around the inflorescences, and a closer look revealed a variety of bees and a few Zelus longipes (milkweed assassin bugs) but few beetles of then oedemerids (false blister beetles). Then I noticed something “lycid-like” approaching the inflorescence, but something about it gave me pause. When it landed, I realized it was another L. lateralis. I was able to pick it up easily (it was not skittish as are most other longhorned beetles, perhaps because it relies on its mimicry to avoid predation), and further searching resulted in a fine series of nearly a dozen individuals, along with one more S. strigosa. Those would be the last insects collected, as beating oaks along the way back to the car still turned up nothing. I suppose I’ll need to make another trip down here if I want to collect Florida Brachys!
On the way back south (though not exactly “on the way home”), I stopped off at the Richloam Wildlife Management Area of Withlacoochee State Forest. Unlike the dry sandhill forest I’d just visited in the Citrus unit, the habitat here is wet sand forest. I was hoping to find stands of sedges (family Cyperaceae—usually found in and along wetlands) that I could sweep in the hopes of finding species of Taphrocerus—a genus of Buprestidae whose North American fauna I’ve been slowly revising over the years. These so-called “sedgy-wedgies” mine the leaves of various species of sedges, and there are still a few species of the genus that I haven’t yet myself collected—including the endemic T. floridanus. Kyle had recommended a location where I might find such sedges, which were abundant along the roadside. I swept them thoroughly, but to no avail.
As I was sweeping, a truck stopped and the driver called out to me and said “I just wanted to let you know I’ve already seen four or five good-sized rattlers here!” I thanked the man for his warning—though in reality I very well may have seen more rattlers in my lifetime than him. The man lingered as I returned to what I was doing—seemingly disappointed or surprised that his warning didn’t result in my immediate withdrawal. I suppose he was expecting me to run back to the car screaming like a little girl who’d just seen a spider. I was actually really hoping to see a rattler afterwards and was disappointed that I did not. The forest at this point was impenetrable, so I walked about a quarter-mile down the roadside, checking the flowers of Rosa palustris (swamp rose) along the way and being surprised to not see a single beetle—or any other insect, for that matter—upon them. In fact, the only insects I saw on anything were two very large “caterpillars”—actually larvae of Cimbex americanus (elm sawfly), a primitive wasp—on Salix caroliniana (Carolina willow).

I crossed the road to walk the other side and soon ran into an Ilex cassine (dahoon holly) tree in full flower that was leaning over the roadside.

I saw a mating pair of Lyconotus lateralis (family Lycidae) on the flowers—their presence alerting me to the possibility of finding their longhorned beetle mimic, Elytroleptus floridanus. Despite finding perhaps a dozen lycid beetles, I found no E. floridanus. Another holly tree further up the road also hosted lycids but no longhorned beetles.

Continuing a quarter-mile the other way past the car and further sweeping of sedges along the way back to the car was fruitless, and the lateness of the hour told me my insect collecting activities for the day had finally come to an end. Neverthess, I was content with series of several nice beetle species in my bottles, including a few true Florida specialities, and made my way back home.
Today I joined the WGNSS Botany Group as we hiked a portion of the Whispering Pines Trail to look for a rare clubmoss, then bushwhacked back to the beginning and went off-trail to a nearby sandstone box canyon to look for rare ferns. We found the clubmoss—Diphasiastrum tristachyum (blue clubmoss)—growing in the shortleaf pine/scarlet oak forest atop a LaMotte Sandstone cliff. Though common in eastern North America and Eurasia, the area in and around Hawn State Park is the only known station for the plant in Missouri, and this population is highly distinct from the next nearest population in Tennessee.

We also found the ferns in the box canyon along with Mitchella repens (partrideberry) growing on the moist sandstone bluff faces of the canyon. This plant is not as rare in Missouri as blue clubmoss, but it is still seldom encountered outside of the LaMotte Sandstone forests of Ste. Genevieve County. An interesting feature of the berries is that they require two flowers to be fertilized and then develop together into a single berry—if you look closely at the berry you can see two “dimples” representing the remnants of the two flowers.

As we hiked I paid attention to the grasses (family Poaceae), which were as diverse as anywhere I’ve been lately (at least, since I’ve started paying attention to such things). Many of them I can recognize easily—river oats (Chasmanthiumlatifolium), little bluestem (Schizachyrium scoparium), Broomsedge bluestem (Andropogon virginica), etc, but many more were new to me, including several species in the large and diverse genus Dichanthelium (rosette grasses). For most of them, rather than trying to identify in the field, I collected samples to look more closely at home with a microscope and my copy of “Steyermark’s Flora of Missouri.”

One of them seems to be D. commutatum var. ashei (Ashe’s panic grass) [identified by Nathan Aaron via iNaturalist], which is distinguished by habitat (intact sandstone or chert woodlands), nodes not hairy, and small stature with leaves clustered towards the tip of the stem. We also saw (but I did not photograph) the common woodland D. boscii, which is larger and has massive spikelets and famously long-hairy nodes. I’ll share the full list here when I can, but it probably numbers around a dozen species.

Insects were not numerous, despite the pleasant conditions, but I did see and manage to photograph a fiery skipper (Hylephila phyleus—family Hesperiidae).

After the outing, several of us enjoyed lunch at the Midway Bar & Grill in Weingarten, Missouri. I had an elk burger, yum!

Last month I made the fifth and final trip to extreme northwestern Oklahoma as part of a trapping study conducted at several locations throughout the area. Recall the main part of the study involved “jug traps” baited with pure ethanol (EtOH), sweet red wine (SRW), or a 50:50 blend of both (SRW/EtOH) to evaluate their efficacy in capturing longhorned beetles (family Cerambycidae). The traps were set in mid-May with the help of my good friend and longtime collecting buddy Rich Thoma (see First insect collecting trip of the season) and checked at ~5-week intervals throughout the season—first in mid-June at the beginning of a 3-week long collecting trip to the southwestern U.S. with another good friend and longtime collecting buddy, Mike Arduser (see 2023 Southwestern U.S. Collecting Trip iReport), then again in late July (see July “jug trap” run) and late August (see August “jug trap” run), and, finally, this last trip in early/mid-October. The July and August trips were solo, but Rich joined me again for this last trip, which concludes two years of data collection for the study (last year traps were placed across extreme southern Missouri). I plan to begin preparing a manuscript this coming winter to analyze and discuss the findings. I hope you have enjoyed “tagging along” with me on these trips as much as I have enjoyed doing them!
Day 1 — 10 Oct 2023 Alabaster Caverns State Park Woodward County, Oklahoma
We got here right around 5:30, which left us only with a couple hours of daylight to get the traps taken down. The jug traps were choked full of Euphoria sepulchralis with some Cotinus nitidus—especially the SRW/EtOH trap, but I did see at least one Eburia sp. so hopefully there will be other longhorns as well. I bagged the trap contents from each of the traps for sorting and counting later (the SRW/EtOH trap was so full that my 1-qt bags weren’t big enough and I had to borrow a 1-G bag from Rich). After retrieving the traps we went back up on top to check the white bottle trap and look for beetles on flowers in the shortgrass prairie above the canyon. The bottle trap had been pulled by an animal, so nothing in it☹️, and the only beetles I saw were Chauliognathus longifolia and a variety of meloids on flowers of Guterrezia sarothrae.

Before long it started getting dark, so we headed down to the campground to set up camp, have a beer (or two), and cook some dinner (ballpark brats!).

After setting up camp we got started on the fire by collected kindling and small branches, one of which was a dead branch I yanked off a small dead Celtis occidentalis. I could tell as I was pulling it off that it had been well infested by wood boring beetles, and as I broke apart the larger portion of the branch (~1” día.) I found a couple of unemerged Euderces pini adults inside their pupal chambers. After dinner we walked the road back up out of the canyon—immediately starting out I found a Tetracha carolina zigzagging crazily on the road, and up on top of the canyon I found two different species of tenebrionid beetles lumbering slowly on the ground in the shortgrass prairie.

Back at the campsite we found a nice Scolopendron polymorpha centipede—Rich collected it very carefully to avoid getting bitten! It was crazy windy up on top but very calm down in the canyon, and temperatures were Goldilocks for sleeping!

Day 2 — 11 Oct 2023
Sleeping temps were again super nice, and after breakfast and breaking camp we retrieved the Lindgren funnel trap. Like the jug traps yesterday, it was inundated with Euphoria sepulchralis, but since I’m not taking data from this trap we sorted through and discarded them all , finding 5 Neoclytus mucronatus, 2 Elateridae, and 1 Sandalus sp.
Collapsed cavern in the morning light.
We went back up to the shortgrass prairie before leaving the park to check the snakeweed and camphorweed flowers again, hoping that Crossidius longhorned beetles and Acmaeodera jewel beetles might be active. I also wanted to see if I could find another of a meloid that escaped my attempts to photograph it yesterday. There was more activity on the flowers, but nothing of interest until I went to the next shelf down and found the meloid (Epicauta stuarti) on flowers of Gutierrezia sarothrae. I wasn’t able to photograph it on the flowers, but I did get a “finger-photo”. I’m glad I was able to find and photograph it, because it turned out to be a new eastern record for the species on iNaturalist, which contains relatively few records for what must be a rather uncommon species.

Nearby I encountered a large, impressive Say’s grasshopper (Spharagemon equale), which I collected thinking Rich would really want it (he did!). Still, I hadn’t seen any Crossidius or Acmaeodera until I went back on top, and on the last clump of G. sarothrae available to check I found one C. pulchellus still embedded down inside the flowers and not yet active. I wonder how many others I missed!
The drive from Alabaster Caverns to Gloss Mountain takes about an hour, so we arrived right at noon. After a bit of lunch, we started out on top of the mesa to check the jug traps. As at Alabaster caverns, they were overwhelmed with Euphoria sepulchralis and lower numbers of Cotinus nitidus, but I did see a few elaphidiine longhorned beetles and elaterid click beetles. Unfortunately the third jug trap (EtOH-only) was broken and with no retrievable trap contents. Trap contents from jug traps A (SRW) and B (SRW/EtOH) were bagged for counting at a later date. The white bottle trap also had perhaps more than 100 E. sepulchralis (no vouchers) plus 1 Meloidae (and 1 wasp, 1 bee for Mike). There was lots of different flowers in bloom, giving me hope that insects, especially beetles, might be found on them. Some, like Polanisia dodecandra (redwhisker clammyweed) are not normally associated with beetles (at least not to my knowledge), but others such as camphorweed (Heterotheca subaxillaris), snakeweed (Gutierrezia sarothrae), and any number of Solidago spp. (goldenrods) are.
Solidago mollis (velvety goldenrod, soft goldenrod, Ashly goldenrod—family Asteraceae) on slope of gypsum caprock clay mesa.
I focused on camphorweed and snakeweed, by far the most abundant blooms out but also flowers in which I’ve found longhorned beetles and jewel beetles previously. No beetles were seen on them for some time, but eventually I found a single individual of Crossidius discoideus on the former and two C. pulchellus on the latter.

Shortly afterwards I finally found Acmaeodera macra, first on the flower of H. subaxillaris and then on the flower of G. sarothrae—both times just a single individual.

Down below I continued checking the snakeweed and camphorweed flowers—to no avail, so I proceeded with checking the traps. The first jug trap (SRW) was broken and no trap contents recovered, but the SRW/EtOH trap was intact and overwhelmed by E. sepulchralis with many fewer C. nitidus and even a couple of Plinthocoelium suaveolens—trap contents were bagged for counting at a later date. The white bottle trap had about a dozen E. sepulchralis (no vouchers) and 1 meloid (plus 4 bees for Mike). I was disappointed that neither of the bottle traps caught any A. macra, which I’d just collected on top of the mesa and, thus, know they are here and active—perhaps their numbers are too low to effectively trap, or perhaps the beetles would prefer a yellow-colored trap to a white-colored one.
Once again there was only about an hour of daylight to work with by the time we got here, so I got to work quickly. I was hoping I would be outside the western limit of the range of Euphoria sepulchralis, which had overwhelmed the traps at Alabaster Caverns and Gloss Mountain State Parks, but such was not the case. Nevertheless, the first trap I checked (SRW) I saw a huge male Tragidion coquus—one of my highest priority target species—sitting on top of the beetles filling the jug! I grabbed it and secured it separately, then bagged the rest of the trap contents. There were other Cerambycidae in the trap, though I did not detect more T. coquus, and the same was also true in the SRW/EtOH and EtOH traps. The white bottle trap had 1 Acmaeodera sp. (prob. mixta) and 4 E. sepulchralis (plus 4 bees for Mike), and after retrieving all the traps and bagging the contents we hiked over to the dunes to watch the sun set in the western sky—we were a tad late, but it was still a beautiful sight.

We quickly headed to the campground to set up camp while we still had (some) light, cook a couple of burgers, and be mesmerized by the gorgeous night sky. While we were setting up camp, I found an emesiine reduviid—a freakish-looking, rail-thin assassin bug that I don’t ever recall seeing before—on the campsite picnic table.
Campfire a blazin’!
Later in the evening before turning in, I walked the roads—as is my custom—to see what beetles or other interesting critters I might come across. I only saw one tenebrionid, but I did encounter a fascinating case of cannibalism —a large Scolopendron polymorpha (desert centipede) that had captured and killed a smaller conspecific. The predator was a bit jittery and dragged its prey as it scurried away from my persistent attempts to look more closely at it but eventually settled down to allow me to see its venomous “claws” (modified first pair of legs) embedded within the body of its victim.

Day 3 — 12 Oct 2023
No lighting again last night, with cool temps and blustering winds that blasted all through the night. We slept comfortably though. We wanted to check the dunes before heading towards Black Mesa—me because I wanted to check the stands of Rhus aromatica (fragrant sumac), on which I had seen (but failed to collect) a single Lampetis drummondii, and Rich to look for fresh animal tracks in the sand. I did not see any Lampetis, but I did pick up a couple of Cicindela formosa and one C. scutellaris. I’d hoped to see more and get in situ photographs on the sand dunes, but it needed to warm up more before that would happen, and we were both itching to get started on our way to Black Mesa.
The first jug trap (SRW) was not very full, and most of what was in there was moths. There were a few Euphoria inda, which had been dominate last time, but once again picking through the catch revealed no Cerambycidae. It was a completely different story, however, with the next two traps. In the SRW/EtOH trap I immediately noticed Tragidion coquus, and picking through the catch revealed at least five individuals. It was the same with the EtOH trap, which had at least four individuals. I did not notice any other Cerambycidae, but since T. coquus was a primary goal for the trapping effort—on top of the one I already got yesterday—I was thoroughly satisfied. The catch from all three traps was bagged for counting at a later date. The white bottle trap had no Acmaeodera sp., one Euphoria inda, and lots of orthopterans that I gave to Rich (plus 105 bees & 6 wasps for Mike). After finishing the traps, we checked several Gutierrezia sarothrae plants in bloom in the flats below the outcrop and, for a while, did not see anything until I found a single Acmaeodera rubronotata on the flowers of one of the plants. I believe this is a new state record (NSR) for Oklahoma—the second NSR I’ve gotten this year and the third in the past two years! We continued checking the G. sarothrae flowers as we walked back up the back road, but no more were seen. I even went back down and rechecked all the plants in the flats below and back up along the road, all to no avail. After I got back up to the vehicle, I returned to the SRW trap to retrieve a dead branch from the Pinus cembroides tree that the trap was hanging in which appeared to be infested with wood boring beetles and was brought back for rearing. There is a decent chance that whatever I rear out of the branches might be a new state record for Oklahoma, since this is the only place in the state where western pines are found—surely the insects associated with them will also be western.

The results for the first two jug trap (SRW & SRW/EtOH) were again similar to the previous site nearby, containing mostly moths, very few E. inda, and almost no Elateridae. However, once again I saw multiple individuals of T. coquus in both of them—what a fantastic result for the final trapping period of the study! Curiously, the third trap (EtOH) had few moths and no Cerambycidae (that I could see), and it was loaded with E. inda. The catch from all three traps was bagged for counting at a later date. The white bottle trap had no Acmaeodera sp. and 10 Meloidae (plus 40 bees for Mike). After we finished the jug traps, but before retrieving the Lindgren funnel trap, we hiked up the Overlook Trail to see if we could again find Lampetis (Spinthoptera) drummondii on the Rhus aromatica bushes (as I’d done last time). Along the way I found a yucca weevil on the trail. Amazingly, in almost exactly the same place as I’d found L. drummondii last time, we found them again—I let Rich have the first one after we both photographed it, and though it took a while we eventually found two more which I collected. With temps dropping and the sun sinking, we hustled back to the car to put away the traps we’d retrieved and then went up to North Canyon to retrieve the Lindgren funnel trap. I did not see any Cerambycidae in it—just moths and a few click beetles and E. inda. This was a disappointing result, considering the jug traps had done so well attracting T. coquus, but I bagged the catch and will go through it more carefully at a later date.

Day 4 — 13 Oct 2023 Jct Hwy 64 & N1250 Rd Beaver County, Oklahoma
Last night was the coldest, windiest night of camping I’ve ever experienced! We were warm in our winter sleeping bags (although I did need to put my socks back on in the middle of the night), but the tent flapping awoke us frequently (and the one or two “necessary” exits from the tent in the middle of the night were not enjoyable!). When we did get up, the only thing we wanted to do was break camp and get in the car and out of the wind asap—breakfast and morning coffee would have to wait until we reached Boise City. All the traps had been checked, and while we had hoped to do a bit more collecting in the park before heading back to St. Louis, it wasn’t an option with temps in the mid-40s and biting north winds at 26 mph—nothing to do but start heading back. Along the way passing back through Beaver Co., we noticed lots of waterfowl in a large, shallow pond near the highway and pulled onto a nearby side road to get a better look at them. Even with binoculars we could only say for sure that they were ducks—they were too far away to identify beyond that. While we were there, I swept the extensive stand of sedges and rushes around the margin of the pond hoping to find Taphrocerus species—in this area I suspect T. chevrolati is the only species that would be encountered. None were found, even after quite a bit of sweeping—just a few flies and one 12-spotted cucumber beetle!

We had thought about stopping at Salt Plain State Park in Woods County, which our route back to St. Louis took us right by, but I had a better idea as we were approaching Alva, which is only 15–20 miles south of Hardtner, Kansas where “Beetle Bill” lives. I last saw Bill in 2004 when I visited him with Jeff Huether, and I thought it’d be nice to stop by and say hey before checking out a spot in the Gypsum Hills just north of town where Cicindela pulchra—one of North America’s most beautiful tiger beetles (the name literally translates to “beautiful tiger beetle”)—has been reported. Sadly, Bill was not in town that day, so we left our regards and continued on to the site.
Temps had warmed up to the mid-60s—warm enough, we thought, that insects should be active, but the winds had not abated in the least (to the point where I eventually decided to leave my cap in the car rather than chase after it repeatedly). Unfortunately, scanning the sparsely vegetated red clay soil at the site revealed no tiger beetles, so I began searching the blossoms of Gutierrezia sarothrae for Crossidius. Most of the scattered plants were on the tail end of their bloom, so there were not a lot of fresh flowers, but eventually I did find three individuals of C. pulchellus on the plants. As I searched the area for additional plants, I encountered the dried out carcass of a black vulture (Coragyps atratus). I don’t normally collect carrion-feeding beetles, but there are a few beetle groups of interest that I’ve encountered on carrion (e.g., checkered beetles of the genus Necrobia and dung beetles of the genus Onthophagus). I brought the carcass to the roadside and slapped it against the road to see what might be dislodged and found two species of Dermestidae. I know people who study these beetles, so I went ahead and collected a series of each—mostly because the host association was sorta cool! No other insects were seen during the visit, but I did encounter a recently-died Celtis reticulata sapling with fresh-looking, frass-packed galleries made by a jewel beetle (prob. Chrysobothris) and, thus, collected it for rearing. By the time I got the wood bundled up and placed in the car, we were both so done with the wind that we decided we’d had our fill of collecting and embarked on the final 7½ hours of driving back to St. Louis.
