2024 New Mexico Insect Collecting Trip iReport: Finale

Welcome to the 16th “Collecting Trip iReport” covering this season’s third—and final—insect collecting trip to eastern and southern New Mexico. This trip occurred during September 9–18, following “Act 2” on June 17–28 and “Act 1” on May 14–25, and had the objective of retrieving 18 “jug traps” and six “bottle” traps placed on the first trip. Unlike the previous two trips, I traveled solo this time, but I still managed to visit 16 different localities—14 in New Mexico, one in Oklahoma, and one in Kansas.

Per usual, this report assembles field notes largely as they were generated during the trip. They have been lightly “polished” but not substantially modified based on subsequent examination of collected specimens unless expressly indicated by “[Edit…]” in square brackets. Unlike my previous two trips this season, I did bring my “big” camera and took lots of macro photographs of insects in the field—these will be featured in future individual posts. However, as always, this “iReport” features iPhone photographs exclusively. Previous iReports in this series are:

Day 1

3.2 mi SSW of Piqua
Woodson County,
Kansas
On my way to Black Mesa State Park (in the northwestern corner of Oklahoma) where I will be spending the night, I stopped at this abandoned quarry at the suggestion of Dan Heffern, who grew up in the area and collected his first Megacyllene decora (amorpha borer) here as a teenager on the Amorpha fruticosa that grows commonly on the steep banks surrounding the now water-filled reservoir.

Abandoned quarry lined with Amorpha fruticosa.

The timing seemed right, as patches of goldenrod (Solidago sp.) surrounding the reservoir were also just coming into bloom, but no adults were seen on either the stems of amorpha or the flowers of goldenrod. I did get to see a garter snake try (and fail) to catch a leopard frog. The snake had hold of the frog by one of its hind legs, but the frog used its other hind leg to eventually free himself while peeping desperately. I was kind of rooting for the frog, even though it would have been interesting to watch the snake as it ingested its prey.

I was hoping to make it to Black Mesa State Park (at the far western end of the Oklahoma panhandle) before dark, but the sun setting on a lonely stretch of highway well beforehand told me that wouldn’t be possible.

I arrived at the park well after sunset, but the tent went up quickly and I found a Cicindelidia punctulata (punctured tiger beetle) on the exposed clay after I finished.

Cicindelidia punctulata (punctured tiger beetle—family Cicindelidae) on clay exposure in juniper chaparral. The greenish cast suggests the population in this area represents an integrade between the nominotypical eastern subspecies and the western C. p. chihuahuae.

This prompted me to put the headlamp on and walk the roads to look for beetles. Amblycheila cylindriformis (Great Plains giant tiger beetle) has been taken in the park, though in July (September is likely a bit too late). Nevertheless, I walked to the spot where it had been found about a mile up the road, scanning the road with my headlamp as I walked.

A few big black Eleodes darkling beetles gave me the occasional false start, but in the end I did not find the tiger beetle. I did, however, get to see a beautiful 1st-quarter moonset amidst light high clouds and a starry starry night.

Day 2

0.1 mi S Hwy 325 on D0035 Rd
Cimarron County, Oklahoma

There is an iNat record of an Amblycheila cylindriformis (Great Plains giant tiger beetle) larval burrow at this spot. Even though the record is a couple of years old, I thought I’d stop by and see if I could find one for myself. I did, fairly quickly I might add, right along the top edge of the steeply-sloped clay embankment alongside the road.

A bit more searching nearby revealed the carcass of an adult embedded in the clay slope—I dug it out (in pieces) and saw the abdomen covered with a bit of spider webbing. I’m still not sure how it came to be embedded within the clay with only the head and probotum exposed.

Mills Rim Campground
Kiowa National Grassland
Harding County, New Mexico

It took a couple of hours of driving to get to this, the first of six trap locations I have in New Mexico. I was happy to see all three jug traps still hanging, intact, and full of catch. All three had lots of Euphoria (mostly fulgida) and a fair number of elaterids, but other than a single Tragosoma sp. (I haven’t collected one of these in many years!) in the SRW trap the cerambycids seemed limited to just a few elaphidiines. The bottle trap had lots of bees (for Mike) and Euphoria kerni, but I did see a few Acmaeodera spp. and—remarkably—another Tragosoma sp. (an unusual catch for a bottle trap!).

While I was checking the traps, I kept an eye out for tiger beetles and flower-visiting longhorns and buprestids. I did see one Acmaeodera rubronotata on flowers of Gutierrezia sarothroides (broom snakeweed), but this was the only one despite looking at many flowers and I chose not to linger.

“San Jon Hill”
9.3 mi S of San Jon
Quay County, New Mexico

Another two-hour drive brought me to “San Jon Hill”—a sandstone escarpment at the edge of a plateau featuring juniper/oak/pinyon woodland. Again, all three of my jug traps were still hanging and intact, and the SRW and SRW/EtOH traps were full of beetles! The EtOH trap, on the other hand, was bone-dry with far fewer specimens. Like Mills Rim, Euphoria (again, mostly fulgida) were dominant, but I was elated to see multiple Enaphalodes hispicornis (a species I’ve never collected) along with a few E. atomarius in all the traps. The SRW/EtOH and EtOH traps also had several Aethecerinus wilsonii—a great find that I first got near Kenton last year. There was also a Stenaspis solitaria in the EtOH trap along with the expected smattering of elaphidiines and elaterids in all three traps. The bottle trap also was overwhelmed, primarily with bees (for Mike), but I did see a fair number of Acmaeodera spp. (I’m hoping this includes A. robigo, one of which was in this trap last time).

Otherwise, I saw little insect activity despite the abundance of plants in flower—a Eusattus reticulatus (sand darkling beetle) crawling on the ground being my only other capture.

Continuing further south towards Oasis State Park, there is a field of wind turbines that, on my previous passing, provided a picturesque scene. This time again provided such opportunity.

The drive from my last stop was supposed to be only 1½ hours, but having to reroute after sitting a while for a motionless train and an unexpected but welcome FaceTime call with my grandson conspired to delay my arrival at the park until well after darkness had settled. No problem—I’ve set up many a tent in the dark, and the burger cooked on the grill afterwards was no less tasty. (I also had sufficient reception to relish watching Kamala Harris clean TFG’s clock, which was followed “Swiftly” by a major endorsement and only served to further buoy my mood.) After the evening’s entertainment, I set out to check a couple of light sources in the park to see if they’d attracted any beetles—a small utility building near the RV campground, and a mercury-vapor streetlight closer to the tent campground. Tenebrionids abounded in number and diversity under both light sources, and I took from each several examples of the weirdly-explanate Embaphion muricatum.

Scarabs were limited mostly to small melolonthine, but I did pick up nice series of at least two species of bolboceratine geotrupids.

I had hoped to encounter the sand dune endemic longhorned beetle, Prionus spinipennis (I don’t know if it actually occurs here), but on my last visit in June I encountered its early-season counterpart P. arenarius. None were seen, however, so I am hopeful that I find it further south at Mescalero Sands, where it is known to occur and where I plan to go in the next couple of days.


Day 3

Passing through Portales in the morning, I did a double-take as I passed this “low rider.” I circled around the block so I could get another look, and for the rest of the day I had the eponymous song from Cheech & Chong’s Up In Smoke as a brain-worm.

“All my friends know the low rider (yeah)”

Portales Recreation Complex
Roosevelt County, New Mexico

My first stop for the day turned out to feature little-disturbed (i.e., ungrazed) dry grassland surrounding the ballfields. There are some iNat records of a couple of fall-occurring longhorned beetles (Megacyllene angulifera, Tragidion coquus) from here, so I thought I’d try my luck as I head south towards Mescalero Sands. The season felt a little early, as even though there were plenty of Helianthus annuus (annual sunflower) in bloom, the Gutierrezia sarothrae (broom snakeweed) was not. Still, I checked the sunflowers but saw only Chauliognathus basalis (Colorado soldier beetles) in abundance. The visit was “not for naught,” however—walking the sandy loam 2-track through the lower west side I encountered three species of tiger beetles: Jundlandia lemniscata rebaptisata (rouged tiger beetle), Cicindelidia punctulata chihuahuae (Chihuahua punctured tiger beetle), and—my favorite—Cicindelidia obsoleta obsoleta (large grassland tiger beetle).

“Mydas Alley”
6.6–6.9 mi S of Floyd
Roosevelt County, New Mexico

There are some iNat records of several interesting tiger beetles at this spot—an endless dry grassland with a sandy/red clay 2-track cutting through it. These include Cicindela formosa rutilovirescens (Mescalero Sands tiger beetle)—a main target for the trip, Cicindelidia obsoleta obsoleta (large grassland tiger beetle), and Cicindelidia nigrocoerulea (black sky tiger beetle).

Sandy-loam 2-track at “Mydas Alley.”

I didn’t have much expectation for the latter, since the record is based on a single, dead individual, and I’d just found C. o. obsoleta at the previous site closer to Portales, but I was really hoping to find C. f. rutilovirescens. Almost immediately I caught what I thought could be C. nigrocoerulea on the sandy/red clay 2-track near where I parked; however, it turned out to be the similar Cicindelidia punctulata chihuahuae (Chihuahua punctured tiger beetle), distinguishable by the single seta on the basal antennomere instead of two (an eyeglass on a lanyard around the neck at all times can really come in handy), its subparallel elytra that are slight wider posteriorly rather than subarcuate, and the generally shinier rather than opaque surface of its elytra.

I found more C. punctulata further down the 2-track (although they looked more like the nominotypical subspecies due to their dark brown rather than greenish coloration), and I found myself paying attention to almost every C. punctulata that I encountered hoping one might be C. nigrocoerulea. Sadly, none would prove to be the latter (at least based on my examination in the field—subsequent closer examination at home may prove otherwise). I did, however, encounter a single Cicindela scutellaris scutellaris (festive tiger beetle) to add another tiger beetle species to the trip list.

At the far end of the 2-track, I noticed something sitting on the stem of Eriogonum annuus (annual buckwheat) and was delighted to see it was Crossideus discoideus—one of the genera of fall-active longhorned beetles that I was hoping to encounter on the trip.

A bit of careful searching in the immediate vicinity revealed more individuals on the stems and flowers of the plants growing in the area, and on the way back I found another C. discoideus on the spent flower of Heterotheca subaxillaris (camphorweed) near the front part of the 2-track. I had not, however, seen my main objective—C. f. rutilovirescens—and was beginning to resign myself to getting skunked on the species. As I reached the car and turned to go briefly down the 2-track to the east, however, I saw one on the more wide open section of the 2-track, then quickly saw another! Those would be the only two I would see until I turned back and approached the car again, seeing the third and final individual of the stop.

I was hoping to get field photos with the “big” camera, but their scarcity made me decide to wait for my next chance at Mescalero Sands, where I hope to find them as well. The number of tiger beetle species seen on the trip now stands at six (if I include the Amblycheila cylindriformis carcass seen yesterday in the Oklahoma panhandle).

Presler Lake
Chaves County, New Mexico

Over the past couple of years, I have begun to rely ever more heavily on the natural history platform iNaturalist as a source for finding promising localities for interesting species. The first two localities I visited today were both found prior to my departure on this trip while searching for localities where species of Buprestidae, Cerambycidae, and Cicindelidae have been recorded. This locality was not found before I left, but rather after I left the last spot and saw that several species of beetles, including Eunota togata globicollis (alkali tiger beetle), had been reported from the area around this alkaline lake.

Alkaline flats around Presler Lake.

As I walked toward the lake, I noticed lots of Isocoma pluriflora (southern goldenbush), normally a good host for Crossidius longhorned beetles, that was already past bloom and wondered if any Crossidius would still be found on them. As I reached the lake margin, I saw a  Crossidius suturalis male, but it was instead perched on Atriplex canescens (four-winged saltbush). No sooner than after I had photographed the beetle, marked its location, and made an entry in my notes, I noticed another—this one a big female perched on the spent bloom of I. pluriflora.

The locality where E. t. globicollis had been recorded was on the far west side of the lake, so I walked the lake margin in that direction while checking the saltbush and goldenbush along the way. It was quite a while before I found another C. suturalis on I. pluriflora, and on another plant very nearby I found a nice little cetoniine scarab: Euphoria pilipennis—a species I’ve never collected before.

The walking and checking was eating up time, however, and I noticed that the sun was beginning to dip rather low in the western sky. I needed to focus on finding E. t. globicollis if I wanted to get back to the car before it got dark (I would still have another hour’s drive to get to my campground near Roswell). I’d walked towards the lake margin earlier, going as far as I could go toward the water before my shoes started sinking into the thick, alkaline-encrusted mud, and didn’t see any tiger beetles, so I was not really expecting to see the species (it had been recorded there during the height of the summer). Remarkably, right as I made my closest approach to the spot, I saw one—E. t. globicollis running on the wet mud near the water’s edge of the alkaline lake.

I walked the margin all the way back to where I needed to divert back to the car and saw several more individual, but I was unsuccessful in capturing any beyond the first one!

Bedtime for tiger beetles approaches.

As I neared the car and the sun sank behind the horizon, I assumed the day’s collecting was done. Just then, I noticed a Gyascutus sp. sitting on Atriplex canescens (based on location, I suspect it is G. planicosta obliteratus), and within a few steps from there I saw another C. suturalis on I. pluriflora. This prompted some additional looking in the area around the car, but eventually the light became too dim to allow effective searching. It was an impromptu stop at an unlikely location and ended up being a successful stop for the trip.


Day 4

Palmer Lake Campground
Bottomless Lakes State Park
Chaves County, New Mexico

I arrived at my favorite campsite in this campground well after dark last night, so I was pleased to see the area as green as could ever be imagined when I awoke this morning. Copious blooms of Allionia incarnata (trailing four o’clock) and Kallstroemia parviflora (small-flowered carpetweed) were blanketing the adjacent gypsum/red siltstone slopes.

Not much of note was seen on the blooms, but I did find the fascinatingly-inflated Cysteodemus wislizeni (black bladder-bodied blister beetle) crawling on the ground amongst them.

A quick walk up into the draw behind the campsite also revealed little besides a variety of darkling beetles (family Tenebrionidae)—some of them monstrously-sized. However, once back at the campsite I found a rather beat up right elytron of what I believe to be Amblycheila picolominii (plateau giant tiger beetle). Since I included A. cylindriformis (Great Plains giant tiger beetle) to my running list of tiger beetle species seen on the trip, I’ll add this one as well as .

Bitter Lake National Wildlife Refuge
Chaves County, New Mexico

I found another iNaturalist record of Cicindelidia nigrocoerulea (black sky tiger beetle) at this refuge, which is located just north of Bottomless Lakes. I didn’t find this species at the previous spot where I looked for it (as far as I know), and since the refuge is managed by the U.S. Fish & Wildlife Service, I can only “look but don’t touch” (no collecting permit). Because of this, I decided to make today a “big camera” day instead of an “insect net” day.

Alkaline flats at Bitter Lake National Wildlife Refuge.

Tiger beetles were scarce on the dry alkaline flats where the record was taken (albeit, many years ago and in July) and limited to the über-common Eunota circumpicta johnsonii (Johnson’s tiger beetle) and Eunota togata globicollis (alkali tiger beetle). I’ve photographed both of these species already but attempted a few shots of each anyway to get some practice (photographing tiger beetles is challenging at best, requiring patience, persistence, and a willingness to get down on the ground no matter how dirty you will get). I found it difficult to approach either species (but especially the latter) in what was by then the heat-of-the-day, and the only shots I managed were of two individuals (one of each species)—engaged in shade-seeking behavior. I did find the mostly complete skeleton of what I take to be a common snapping turtle (Chelydra serpentina).

The margins of the oxbow lake on the other side of the parking lot were much wetter, and accordingly the tiger beetles were much more abundant there as well. In addition to the aforementioned E. c. johnsonii, which here also was by far the most abundant species, I observed Cicindelidia ocellata ocellata (ocellated tiger beetle)—common throughout the southwest, and Cicindelidia tenuisignata (thin-lined tiger beetle)—much less commonly encountered and a species I’d first seen during my previous trip to Bottomless Lakes in June. I managed to photograph a mating pair of E. c. johnsonii, but try as I might I was unable to photograph C. o. ocellata or C. tenuisignata—a rather deflating failure for someone who prides himself in his tiger beetle photography skills. For now, the iPhone photos that I took last time of individuals of the latter species attracted to ultraviolet light at night will have to do. There was a good amount of Isocoma pluriflora (southern goldenbush) still in good bloom around the parking lot, and I managed to photograph a fine male Crossidius suturalis suturalis on the flowers.

Chaves County, New Mexico

The day’s high heat not only made futile any further attempts to photograph tiger beetles at Bitter Lake, but gave me pause about going out for more collecting as soon as I returned to my campsite—I needed a bit of time to chill. Eventually, however, I worked up the motivation to strap on the pack and grab the net. I had earlier noticed a nice stand of Isocoma pluriflora (southern goldenweed)—a good host for Crossidius longhorned beetles—at the end of the campground road, and that became my first destination. It took a bit of time before I found C. s. suturalis on the flowers, but after working the stand for about an hour I had a nice handful.

Many other insects were also visiting the flowers, most visibly a large Pepsis tarantula hawk (prob. P. grossa)—which I could not photograph—and numerous colorful blister beetles that I take to be Pyrota concinna—which I did photograph.

I next visited the small, slightly elevated picnic area next to the campground, where last time I had collected a small series of a nice, large buprestid, Gyascutus planicosta obliteratus, on Atriplex canescens (four-winged saltbush). I saw one yesterday at Presler Lake, and I hoped they might be still hanging around here as well, but no dice. I did, however, notice a small beetle clinging onto the foliage of Neltuma glandulosa (honey mesquite, formerly Prosopis glandulosa), which turned out to be a very late-occurring Acmaeodera mixta. I noticed that the temps were suddenly getting milder, signaling the onset of evening and reminding me to head back to camp since I wanted to drive to Mescalero Sands (about 40 miles away) for some evening/night collecting.

Mescalero Sands Recreation Area
Chaves County, New Mexico

There are two species of Prionus longhorned beetles endemic to the sand dunes of southeastern New Mexico and western Texas—P. arenarius, which occurs during spring and early summer, and P. spinipennis, which occurs during late summer and fall. I’ve collected the former twice—once several years ago here at this very spot, and again this year at Oasis State Park back in June. I’ve never collected P. spinipennis, however, and figured they should be out by now. I had brought with me a few prionic acid lures, to which the males are attracted (prionic acid is a main component of the pheromones that females of all Prionus species release to call mates), and I also hoped to find and photograph the sand dune subspecies of Cicindela formosa—i.e., C. f. rutilovirescens (which I found yesterday near Portales but did not photograph). Unfortunately, my arrival just 20 minutes before sunset precluded the latter possibility, so instead I hiked into the dunes a short distance to place the pheromone lures and enjoyed a spectacular sunset and moonrise, with the sky morphing from blue to orange before finally turning black.

As soon as darkness fell, I began scanning the sand for anything crawling. Darkling beetles (family Tenebrionidae) appeared in numbers and diversity—my favorites, as always, being the weirdly-explanate Embaphion muricatum, which were as common as I’ve ever seen them.

A sand dune endemic Jerusalem cricket, Ammopelmatus mescaleroensis (Mescalero Jerusalem cricket), some of them being quite large, was also quite common.

About an hour after sunset, I finally saw one—a male P. spinipennis walking urgently across the sand in the general direction of the pheromone lure. I was glad my hunch had paid off and waited to see when the next male would arrive.

Sadly, I waited and waited—expectantly walking the dunes in the area around the vicinity of the lure looking for the next one, but it never came. Perhaps I am a bit on the early side of their adult activity period. Nevertheless, one is better than none, and it gives me a reason to look forward to returning to the dunes some other time during the heart of the fall season. After an hour had passed with no other individuals seen, I called it a night and drove back to my camp at Bottomless Lakes, where the pre-dawn sky was a star-studded as I’ve ever seen!

Day 5

7 mi E of Queen, X Bar Rd
Eddy County, New Mexico

My original plan was to leave today and spend the next two days at Dog Canyon Campground in Guadalupe Mountains National Park just across the Texas state line. That would serve as a base from where I could service the traps that I have on the New Mexico side of the line and also afford me an opportunity to take a day off of collecting and hike the park’s spectacular system of trails. Unfortunately, when I went online a few days earlier to reserve my campsite, I learned that the campground was closed until December due to a water line break! This was a major disruption to my plans, because the only other campgrounds between Bottomless Lakes and Dog Canyon are private KOA-types (ugh!) and the dreadfully ugly Brantley Lake State Park! I decided then to keep my campsite at Bottomless Lakes and just drive to the Guadalupes to service my traps. Afterwards I would drive back and spend an extra night in the far roomier and more beautiful campground at Bottomless Lakes. Again, I was pleased to see the SRW trap hanging and intact, although the reservoir had developed a slow leak and was nearly drained. The catch, however, was still moist, suggesting that the leak had developed only recently and, thus, had no negative impact on data collection. The catch was similar to “San Jon Hill” in that there were numerous Enaphalodes hispicornis and smaller numbers of E. atomarius, Eburia haldemani, and a variety of smaller elaphidiines. Sadly, the SRW/EtOH trap had self-destructed—the bottom half of the trap was found lying on the ground not far from its still-hanging upper half (w/ bait even in the still-hanging bait bottle). The EtOH trap was also hanging and intact, though the bait bottle was dry (I’m seeing this pattern repeatedly—SRW and SRW/EtOH bait bottles still have some bait after 10 weeks in the field, but EtOH bait bottles are dry); however, there were only a few small elaphidiines representing the cerambycids. The white bottle trap had a decent catch of Acmaeodera spp. and bees (for Mike). However, there wasn’t much else going on insect-wise (the chunky, remarkably rock-like nymph of Leprus sp.—either L. intermedius [Saussure’s bluewinged grasshopper] or L. wheelerii [Wheeler’s bluewinged grasshopper]—notwithstanding).

The lack of insect activity had me ready to leave as soon as I finished retrieving the traps. However, as I was emptying the last jug trap, I noticed that Dasylirion leiophyllum (smooth sotol) was growing in the area and decided I should check them for Thrincopyge buprestids—colorful species that breed in the newly senesced flowering stalks of the plants. I checked a few without success and suspected it was probably too late in the season to find the adults, then broke an old flowering stalk off of one of the plants and saw the characteristic adult emergence holes of the beetles in the lower part of the stalk. This at least confirmed their presence in the area. Then I saw a plant with a newly senescing flowering stalk. Cutting into the lower portion of the stalk revealed a fresh, frass-packed larval gallery, suggesting larvae are currently working inside the stalk, so I broke the stalk from the plant, carried it back to the car, and cut/bundled it up for transport back home and placement in a rearing box. With luck, the larvae will complete their development to adulthood and emerge next spring.

5.6 mi E of Queen
Eddy County, New Mexico

On my last visit to the area, I found Cicindelidia laetipennis (polished-winged tiger beetle, formerly C. politula petrophila) just over the Texas state line at high elevations in Guadalupe Mountains National Park. I was hoping to see (and properly photograph) it again this time, but the closure of Dog Canyon Campground nixed those plans. Fortunately, I found an iNat record for the species on the New Mexico side of the line (in fact, less than two miles from my previous trapping spot) and made plans to see if I not only could find it but photograph it with the “big camera.” As it turned out, the habitat was perfect—a wash of exposed limestone on a short 2-track above 5000’ elevation.

For the majority of the time I was there, however, I didn’t see any individuals. I did find the occasional Acmaeodera rubronotata on flowers of Eriogonum hieraciifolium (hawkweed buckwheat) and a lumbering Tenebrionidae that I take to be Philolithus aeger crawling on the clay portion of the 2-track.

On the way back, however, I saw the first individual, and not too long afterwards I saw the second. These would be the only individuals I would see—not nearly enough to get my camera gear and hike back in an effort to get proper field photos. Once again, my previous iPhone photos will have to do for now.

Back at the car I was about to pack up and move on to my next trap location when I noticed Grindelia nuda (curlycup gumweed) in bloom around the parking area. Since I’d collected a small handful of A. rubronotata on buckwheat flowers, I thought I might check out the gumweed flowers as well. Not only did I find several more individuals of that species, I also found one individual of A. opacula (formerly A. disjuncta).

As with the season’s previous two visits to this spot, the area looked dry and flowerless. Such conditions rarely warrant making the effort to take a closer look at things, and I wanted to get back to Bottomless Lakes with enough daylight left to search for tiger beetles at an area in the park that I not checked before—Lea Lake Recreation Area. With this in mind, I set about retrieving the traps and was happy to see the SRW trap hanging and intact (this trap was down last time due to rope failure). Also, even after nearly three months, the reservoir was moist and the bait bottle still had bait. There were lots of cerambycids in the catch, including several Enaphalodes hispicornis, E. atomarius, Tragidion coquus, Eburia haldemani, and smaller elaphidiines. The SRW/EtOH trap also, thankfully, was still hanging and in much the same condition as the SRW trap, but I did note far fewer cerambycids. This also seems to be the trend that I have noticed over the last two seasons of comparing these baits (although I must await stats analysis to see how real this is). The EtOH trap was also hanging and intact with plenty of liquid in the reservoir, but the bait bottle was dry (same as other locations), and there were hardly any cerambycids (same as some, but not all, other locations). Sadly, the white bottle trap was completely missing—I even managed to find the exact hole where it was pulled from, but the trap itself was nowhere in sight. This was frustrating, because it was by far the best-performing bottle trap on my last visit. I hate to think that someone deliberately stole it, but the thought is hard to resist—animals (primarily raccoons) often pull traps to eat the catch, but they don’t take the trap with them.

I’d been wanting to look for tiger beetles around Lea Lake since I arrived and was planning on today being the day. Unfortunately, the extra time I spent at the previous spots beyond retrieving the traps (i.e., for cutting up the sotol stalk and looking for Cicindelidia laetipennis)—along with an unplanned but needed stop for supplies—resulted in me arriving only 20 minutes before sundown. There was a particular tiger beetle species I was looking for—Cicindelidia haemorrhagica woodgatei (Woodgate’s tiger beetle), of which several observations from here had been posted on iNat. The alkaline flats right alongside the lake looked perfect for tiger beetles, and I immediately began finding and collecting a variety of tiger beetle species.

Lea Lake.

Most were expected—Eunota circumpicta johnsonii (Johnson’s tiger beetle), E. togata globicollis (alkali tiger beetle), and Cicindelidia ocellata ocellata (ocellated tiger beetle). One individual, however, gave me pause—both when I first saw it and then when I pulled it from the net. At first glance it looked like the über-common and widespread Cicindelidia punctulata (punctured tiger beetle), but it didn’t seem quite right for the species, and its dark coloration contrasted with the greenish color exhibited by most individuals in this area (representing the western subspecies, C. p. chihuahuas, or Chihuahua tiger beetle). Then I noticed the rather rounded elytral sides and the generally dull elytral surface and immediately suspected that I had just collected my first Cicindelidia nigrocoerulea (black sky tiger beetle)—a goal for the trip and one that I had not succeeded in finding at three locations I had gleaned from iNaturalist and visited earlier! Closer examination of the photo and the specimen convinced me I was correct, so even though I did not find the species I was looking for, I still found another one that was a priority for the trip. [Edit: after some discussion, the consensus on iNaturalist is that this individual represents C. punctulata. Alex Harmon noted the elytra sides aren’t round enough for C. nigrocoerulea and that the texture is better for C. punctulata. He also noted that, for what it is worth, that C. nigrocoerulea are either blue, green, or black rather than brown as in this individual. After looking at my field guide upon my return back home, I am inclined to agree with him.]

With the sun setting rapidly and so many tiger beetles still around, I decided that I would delay my departure from the area in the morning and come back to Lea Lake—perhaps I will still find C. h. woodgatei after all!

Back at camp after cooking dinner (salmon—more on this), I decided to “night walk.” I hadn’t had a chance to do this the previous two nights because of reasons, and I wanted to take advantage of one last opportunity to look for Amblycheila picolominii (plateau giant tiger beetle), which I found on both of my previous visits here this year. The closest and easiest place to get to where I had found one was at the bottom of the steep, narrow ravine coming off the gypsum/red siltstone slopes just behind my campsite, so I headed there first. Within minutes after clambering down into the bottom of the ravine, I found one!

Filled with optimism about finding more, I searched the remainder of the ravine bottom, but no more were seen. After emerging from the ravine back at the campsite, I sat at the table briefly to update my field notes before continuing to other areas. At one point I looked up, and there was another one right at my feet! I looked away briefly to grab a vial, and when I looked back it was gone—nowhere to be seen! I searched the entire campsite in a gradually enlarging spiral, but to no avail. I started questioning whether I had actually seen what I was sure I had seen—there are few places to hide anywhere in this very large campsite, and I could not understand how such a large and conspicuous beetle could completely evade me like that. That would ultimately prove to be the last individual “seen” during the entire evening. Nevertheless, during my spiral search I encountered an interesting situation at the “salmon oil pit” (I had rinsed the accumulated oils from the salmon before cooking it and dumped the wash into a small pit that I dug in the soil). There were two tiger beetles inside the pit—Tetracha carolina carolina (Carolina metallic tiger beetle) and Eunota circumpicta johnsonii (Johnson’s tiger beetle)—presumably scavenging on the tasty oils saturating the soil (tiger beetles are well known scavengers when the opportunity arises).

Also during my spiral search, I found several Cysteodemus wislizini (black bladder-bodied blister beetle), each perched on the foliage of Tribulus terrestris (puncture vine). I didn’t know if there was any significance to the association, but I found them on no other plant (the significance would be revealed the next morning). Lastly, I encountered several individuals of a tank-like species of Stenomorpha darkling beetle in the mesquite/saltbush chaparral next to the campsite. I am unsure of the species (the genus is super diverse), but I collected a few specimens and will eventually update their identity in the iNat observation that I posted.

I spent a fair bit of time walking the roads afterwards and even went to the picnic area on the other side of Pasture Lake Campground to see if I could find more A. picolominii, but as alluded to earlier that effort would prove futile. At the end of the fifth collecting episode for the day (interspersed with five hours of driving), I collapsed exhausted onto my cot with a few minutes to spare before midnight!


Day 6

As I was drinking my morning coffee and working on yesterday’s field notes, I noticed another Cysteodemus wislizini (black bladder-bodied blister beetle) on Tribulus terrestris (puncture vine) where I had collected a few on the same plants the night before. This one, however, was not only perched on the plant, but also consuming its flowers. I would see two more on the same plants during the course of the morning, so it seems there is at least an adult floral host association between the beetle and this plant.

Before leaving the park, I wanted to spend some time looking for tiger beetles at Lea Lake. I’d gotten only a quick taste of the fauna there with yesterday’s 20-minutes-before-sunset visit, during which time I’d collected four species, including the new-for-me Cicindelidia nigrocoerulea (black sky tiger beetle), and I was hoping today to add a fifth—Cicindelidia haemorrhagica woodgatei (Woodgate’s tiger beetle) which has been reported here several times already. This time I started at the east end of the alkaline flats, seeing and collecting another C. nigrocoerulea as well as a few individuals each of the other three species I’d seen yesterday—Cicindelidia ocellata ocellata (ocellated tiger beetle), Eunota circumpicta johnsonii (Johnson’s tiger beetle), and Eunota togata globicollis (alkali tiger beetle)—on the alkaline flats along the lake margin. I noticed Isocoma pluriflora (southern goldenbush) at the far end of the flats and checked them for Crossidius suturalis, finding a handful of individuals on the flowers, before turning my attention back to tiger beetles and working my way towards the west side of the lake. I wanted to get proper field photographs of the species I had not yet done so (at least, with the “big camera”), which at that point were only C. nigrocoerulea and C. o. ocellata. I never did see another of the former, but the latter were common enough that I was able to “work” a few individuals before finding a (relatively) cooperative one. I hadn’t planned on collecting any more individuals of E. c. johnsonii, but then I encountered two beautifully sumptuous green individuals and couldn’t resist.

Shortly afterwards, I noticed several individuals of a species I’d not yet seen at that location—Cicindelidia tenuisignata (thin-lined tiger beetle)—in an area of the alkaline flats that was wet from lake water lapping over the edge. I was able to not only collect a handful of specimens, but also get decent photographs of one of them—making moot my inability yesterday to photograph this species and C. o. ocellata.

In the same area, I thought I’d collected a third C. nigrocoerulea, but it turned out to be the common Cicindelidia punctulata (punctured tiger beetle) with which it can be confused. Interestingly, it was dark-colored (as in the eastern subspecies—C. p. punctulata), not green (as in the western subspecies—C. p. chihuahuae). In the end, the number of species seen around the lake increased to six, but—unfortunately for me—C. h. woodgatei was not one of them. By then I’d been at it for two hours, and the heat of the day (99°F) was upon me. Such temps are no good for trying to photograph tiger beetles, so I found some shelter to eat a bit of lunch and then started west towards my next set of traps at a high elevation site near Cloudcroft.

Escaping the heat during lunch.

I always enjoy the drive from Roswell to Cloudcroft—searing desert heat yields to cool mountain air, and the landscape morphs from a flat, featureless, heavily-populated (and, thus, littered) plain, to sweeping, undulating hills of juniper chaparral, to foothills of oak woodland, and finally to bonafide mountains with dense forests of stately pines and firs.

Prime property south of Roswell.

Poetically, I was greeted at the higher elevations by not only cool air, but rain (I think it has done this on every trip I’ve made in this direction). The rain was nothing more than sprinkles, though with a brief 1–2-minute windshield-cleaning episode. By the time I reached my trap locality, clouds remained, but the rain had moved on. I picked this locality because of its ease of access to the precise habitat I wanted to sample—Gamble’s oak forest. When I first encountered the location in May (and again when I returned to service the traps in June), the area was deserted—just what I want in a trapping locality to minimize the chance of vandals finding and disturbing the traps. This time, however, I was horrified to find the area choked with vehicles and tents—the place was literally teeming with people. I got a bad feeling in the pit of my stomach about whether I would find my traps still hanging and intact, and these fears were confirmed when I approached the location of the SRW trap and found it was completely missing—not a shred of evidence that the trap had ever been there! This was really disappointing for obvious reasons, but, additionally, this was the trap that produced the most interesting catch of all traps at all locations on the previous visit. Fortunately, the SRW/EtOH trap was still hanging and intact with liquid in the reservoir and bait in the bottle. The catch was voluminous and appeared to consist largely of flies, yellowjackets, and butterflies; however, fingering through it I did find some interesting longhorned beetles: Tragidion coquus, Stictoleptura canadensis (a new addition to the list of species trapped), and the previously captured Stenocorus copei. This lifted my spirits a bit knowing that at least one trap had survived the human onslaught. The lift, however, was short lived when I approached the EtOH trap and found it lying on the ground—completely disassembled! I found most of the parts, but the nylon rope and carabiner used to hang the trap were gone—someone actually had to untie the rope at one end and unclip the carabiner at the other to take them. I really don’t understand the depravity of people that mess with other people’s stuff with no regard or remorse. Vandalizing traps not only wastes my time, effort, and expense, but in this case it also negatively impacts the integrity of the study I am conducting. It’s hard enough trying to anticipate and mitigate against weather, animals, equipment failure, and errors in deployment without also having to outfox the criminal element. I’ll have to consult with a statistician on the best way to analyze the trapping results while taking into account the loss of some trap events (i.e., unique trap/date combinations). On a positive note, the white bottle trap that I reset last time was still in place and had captured a nice quantity of both Acmaeodera and Anthaxia.

Hwy 70 at “Point of Sands”
Otero County, New Mexico

After checking the traps near Cloudcroft, my original plan was to camp at Upper Karr Canyon, a high elevation national forest campground south of Cloudcroft. However, seeing the zoo of campers at the trapping site, along with the throngs of people and cars I’d seen in town, suggested to me that any campground in the area was probably already filled to capacity on what I realized was a Saturday night of a holiday weekend (Monday is Mexican Independence Day). I noted that my next trapping location at Aguirre Springs Campground in the Organ Mountains-Desert Peaks National Monument was another 2-hour drive, but that I had plenty of time to make it there before dark—even if I stopped and collected along the way. Heading straight there wouldn’t solve the problem of finding an open campsite on a Saturday night, but at least the location was further removed from a town teeming with visitors. As for collecting along the way, I could think of no better spot than “Point of Sands”—a spot along U.S. Hwy 70 where the dunes of White Sands National Monument breach the fenceline and continuously spill out onto the highway. It’s a chance to get a quick taste of the dune flora and fauna without the need for permits, entry fees, etc. I stopped here also on both trips earlier this season, and while I didn’t find much out of the ordinary either time, I keep returning for two reasons—Acmaeodera recticollis and Sphaerobothris ulkei, two rather uncommon and desirable buprestid species that breed in Ephedra (jointfir). I collected a small series of the former here a couple of years ago, but my only evidence that the latter occurs here is a carcass I found lying on the ground a few years earlier. Someday, I will come to this spot at the right time and find adults of that species active on the Ephedra. Once again, however, that time would not be this time—despite the much more comfortable conditions than last time (when temps were 108°F), the only insect I saw worth putting into a bottle was the tank-like darkling beetle, Philolithus aeger, crawling on the white sand.

I also had hopes of finding Crossidius longhorned beetles when I noted stands of Isocoma pluriflora (southern goldenbush) and Gutierrezia sarothrae (broom snakeweed) in bloom—both of which are favored hosts for beetles in this genus. None were found, however—just blister beetles, so after completing the circuit up one side of the road and down the other, I continued the drive to Aguirre Springs.

My fears about the campground being filled seemed realized as I entered the loop and saw site after site already occupied. Fortunately, on the backside of the loop I found a few unoccupied sites, one of which was quite nice—buffered from the view of the road and nearby sites by trees and shrubbery and with a nice level area for the tent. It felt good to be back in one of my favorite places, and another “dirty burger” dinner tasted quite good!

Afterward, I walked the loop to see if I could find any beetles (hoping for Amblycheila, of course), but the only thing I saw were the occasional Eleodes darkling beetle and the glowing eyes of spiders, including the always charismatic Geolycosa sp. (burrowing wolf spider).

Day 7

In the morning, I decided to relax a bit and work on my field notes while enjoying coffee and the views, then headed out to retrieve my traps.

The spectacularly jagged peaks of the Organ Mountains loom over oak woodlands below.

Yesterday’s poor trap fortune turned around completely when all three traps were found in place, intact, … and loaded with beetles! These included several species of elaphidiine longhorned beetles and a diversity of cetoniine scarabs. Two species of the latter group were Cotinis mutabilis (figeater beetle) and Gymnetina cretacea sunbbergi—both new for me! I don’t think the former is all that uncommon, but the latter apparently represents a recently-described subspecies that is endemic to the Organ Mountains.

The same pattern of fewer beetles in the EtOH trap was found here, although all three traps displayed greater total mass than their respective counterparts at other locations. After retrieved the EtOH trap, it hit me that I had just taken down the last trap at the last location in the final season of the 3-year study! There is still much work still to do—specimens to sort, prep, mount, and identify… data to assemble, crunch, and ponder… manuscripts to write, polish, submit, and revise… co-authors to correspond with and coordinate. However, with all that said, finishing the field work still feels like a major victory! At this point, I have no other place where I must go, so I am content to spend the rest of the trip exploring this beautiful area (this makes up for me not getting to spend a day hiking in Guadalupe Mountains National Park).

As I was retrieving the traps, I scanned the nice variety of plants in bloom for beetles and quickly encountered not only Crossidius pulchellus on flowers of Gutierrezia sarothrae (broom snakeweed), but also Acmaeodera opacula, A. amplicollis, and A. rubronotata on the same as well. These are all late-season, mid- to high-altitude species, and surely the floral associations are well known. However, i did find two potential new ones—A. amplicollis (observed) and A. rubronotata (collected) on flowers of Pectis papposa (chinchweed). I don’t recall encountering this plant in my review of literature on host associations of North American Buprestidae and will have to look into this when I return from the field.

On the way back to camp to drop off the traps and refuel, I saw a Euphoria verticalis crawling on the broken granite substrate.

I’d gotten iPhone images of three of the Gutierrezia-associates, but since I have some flex time I decided to grab the big camera and see what kind of real photos I could get. I walked to an area with blooming Gutierrezia much closer to my camp on the south side. I found several C. pulchellus, photographing a mating pair, but persistent searching beyond the area never turned up any of the buprestids. So I looped back through the campground and walked back to the ravine I’d visited earlier. There, back up and down the ravine, I photographed C. pulchellus, A. rubronotata, and A. amplicollis (I never saw another A. opacula beyond the first). I then tuned my attention to other subjects: a snout butterfly, a scoliid wasp, a few plants, and something for a future quiz. I was content with the day and strolled back to camp to rest and cook dinner (steak!).

Dusk settles over Aguirre Springs Campground.

After dinner (and a thrilling football game between my beloved Chiefs and rival Bengals!), I did my “night walk,” this time leaving the campground loop and walking along Aguirre Springs Rd a short distance before turning back. Again, I encountered Eleodes darkling beetles—this time congregating on the trunk of a very large juniper cadaver—and the siren call of a wolf spider’s glowing eyes luring me in for images. I managed a dorsal shot, but she skedaddled before I could fire off a frontal portrait. [Edit: discussion on iNaturalist suggests this is an undescribed species currently known as the “big-eyed” Hogna with its pale, ghost-like markings. It seems to be common in New Mexico.]

Day 8

I didn’t sleep well—my stomach began rumbling in the middle of the night, and by the time I got up I had full-blown GI problems. I had wanted to go down to lower elevations before the temperatures got too high in hopes of finding late-season “hangers on” of larger southwestern buprestids in the genera Gyascutus and Lampetis, but it seemed prudent instead to take it easy during the morning and give myself a chance to feel better. This did seem to happen… eventually… or perhaps it was just the product of wishful thinking!

Morning at Aguirre Springs Campground.

Doña Ana County, New Mexico

I went to a spot where late-season occurrences of Gyascutus, Lampetis, and Acmaeodera had been recorded on iNat.

Bar Canyon Trail ascends from Soledad Canyon Rd on the west slope of the Organ Mountains.

I got an early indication of good luck when I found Acmaeodera rubronotata and A. opacula on the flowers of Picradeniopsis absinthifolia (hairyseed bahia). I also found another Cotinis mutabilis (figeater beetle), this one on flowers of Gutierrezia sarothrae right around the parking lot.

A bit further up the trail, I found two additional species—A. amplicollis and A. maculifera—also on P. absinthifolia, and further still along the trail I found more of the former.

Alongside the trail was a wash, where Fallugia paradoxa (Apache plum) was growing—checking the flowers was, for the most part, fruitless; however, I did find on them singletons of A. opacula and A. rubronotata. There were other plants in flower as well that seemed like they should be good beetle hostsnotably Gymnosperma glutinosum (gumhead), from which I collected a single A. rubronotata. Otherwise, however, there was little to be seen (except the occasional monstrous lubber grasshopper).

I was happy to see the variety of Acmaeodera on P. absinthifolia flowers—especially A. maculifera, a species I had not seen for two decades(!), but my GI problems seemed to worsen as I felt increasingly weak and overheated. Less than one mile up the trail, I simply couldn’t continue further and turned back towards the car for—what I thought—was an end to the day’s activities.

Doña Ana County, New Mexico

After a quick stop in town to purchase symptom relief, I intended to go straight back to the campground and rest for the remainder of the day. Apparently unable to stick to a good plan, however, I decided to scan iNat one last time to see if there were interesting records of Buprestidae from nearby areas and saw that A. maculifera had been taken in a wash just a few miles away. I couldn’t resist the temptation to take one more look at one more spot before heading back up the mountain. Walking down into the wash felt like descending into a furnace! It was by then mid-afternoon, and even though I had rehydrated I still felt weak on the feet. The promise of beetles, however, continued singing its siren song, and I quickly found what proved to be Heterotheca zionensis (Zion false goldenaster) abundantly in bloom and looking like a perfect host for Acmaeodera.

At first I found nothing, but with continued searching I found a spot where several Crossidius pulchellus and a single Acmaeodera scalaris were seen clinging to its flowers—the latter being another buprestid species for the trip (though, admittedly, a rather common species). I managed to finally find several A. maculifera on the flowers after additional searching (along with A. opacula), but I was declining rapidly and decided best to turn around. Passing near the spot where I had first found beetles, I found more A. maculifera (along with A. rubronotata) and lingered to better my series. This last little delay, however, proved to be too much for me, and for the first time ever I experienced “being sick” in the field! My body was sending me a message, and it was loud and clear (not that it wasn’t loud and clear before then!). I went back up the mountain and spent the rest of the day sleeping and resting in the cool mountain air back at camp.

The view from my campsite is simply breathtaking!

Day 9

My original plan for the day (depending on how I was feeling) was to break camp and start heading back to the northeast. With luck, I would make it to the Oklahoma panhandle with enough daylight to explore a few localities in Texas Co. that I hadn’t visited before. I did get a much better night’s sleep; however, I still felt weak and had to take my time breaking camp. This delayed my planned early morning departure a bit, and the need for frequent stops made a pre-evening arrival even less likely. In the end, it didn’t matter as rain moved through the area, bringing abruptly cool, cloudy conditions and wiping out any hope of any insect activity in the waning hours of the day. I did, however, get to see an oversized Texan as I sliced through the uppermost tip of that oversized state and was greeted by an ironically hypocritical welcome sign as I entered adjacent Oklahoma.

An oversized Texan!
An “unwelcoming” welcome sign. Do they even see the irony?

Day 10

3.2 mi SSW of Piqua
Woodson County, Kansas

I got another text yesterday from Dan Heffern, who told me that his brother had found several Megacyllene decora (amorpha borer) on Amorpha fruticosa near his home in eastern Kansas. I had already checked the nearby locality near Piqua (where he had seen this species many years ago) without success, but I reasoned that it may have been too early and that another look (now that the species is known to be out) was warranted. I was feeling better, but not great, and was, thus, glad to encounter relatively mild conditions when I arrived. On the very first clump of Amorpha that I checked, I found a big Megatibicen dorsatus (bush cicada) female sitting on its stem, …

…and shortly afterwards I found the left elytron of M. decora on the ground amidst Amorpha and flowering Solidago sp.

“What luck!”, I thought, and proceeded to inspect each Amorpha clump and flowering Solidago that I could find. Remarkably, my search for adults would prove fruitless, and for the second time on the trip I would have to walk away from the spot empty-handed. I was also starting to feel weak and overheated again after an hour of searching, suggesting that I was still not recovered and that perhaps I should focus on finishing the drive to St. Louis so I could recover in the comfort of my home—a rather inauspicious ending to what was, by all other measures, as fun and successful a collecting trip as I could ever hope for!

2024 New Mexico Insect Collecting Trip iReport: Act 1

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.

Day 1

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.

Moneilema annulatum (ambulated cactus beetle—family Cerambycidae) on Opuntia phaeacantha (brown-spined pricklypear cactus).

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.

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.

“Jug” trap baited with a 50:50 mixture of sweet red wine and 99% ethanol hanging in soapberry tree.

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 Eleodes longicollis 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.

Stalking tiger beetles!

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
Eddy
County, 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”
X
Bar 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.

Alpine meadow at Switchback Trail trailhead.

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.

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.

Penstemon jamesii (James’ penstemon—family Plantaginaceae) in pinyon/oak/juniper woodland.

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!

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 Quercus mohriana (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!

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!

Super duper June bugs

Last June, after spending the day collecting insects at Sand Hills State Park in south-central Kansas with Mary Liz Jameson, Jeff Huether and I setup our blacklights at the edge of the dunes. We were hoping to attract males of the genus Prionus, following a hunch that maybe the dunes—a popular historical collecting site—would prove to be the habitat for the enigmatic Prionus simplex (known only from the type specimen labeled simply “Ks.”). We knew it was a long shot, made even longer by a bright moon and the unseasonably cool temperatures that settled over the dunes as the sun dipped below the horizon, and in the end no Prionus would be seen. We did see, however, some other interesting insects, one of the more interesting being males of Hammond’s lined June beetle—Polyphylla hammondi. Almost immediately after sunset a number of these large, chunky-bodied beetles resembling super-sized versions of their far more diverse and commonly encountered relatives in the genus Phyllophaga (May beetles) began arriving at the lights—each one noisily announcing its visit by its loud, buzzing, flight and bumbling thud onto the ground nearby.

Polyphylla hammondi

Polyphylla hammondi | Sand Dunes State Park, Kansas

I’ve encountered beetles in the genus Polyphylla only occasionally over the  years, almost always at night as a result of their attraction to lights. The genus is most diverse in the southwestern U.S., and many species are found only in specific sand dune habitats (Young 1988, LaRue 1998). Their large size, relatively more restricted distributions, and less common occurrence make them interesting enough, but what made this encounter particularly interesting for me was the way the beetles—all males—held their fan-like antennae splayed out. Male Polyphylla have greatly enlarged antennae that they use to detect sex pheromones emitted by the female (Lilly and Shorthouse 1971). Many female Polyphylla are flightless, especially those restricted to sand habitats, and are rarely collected, and for some species they still remain unknown. In fact, the best way to find females is to listen for the sound of the males hitting the ground or vegetation once they have located a female (Skelley 2009).

Polyphylla hammondi

Male with antennae splayed to detect female pheromone.

It was clear to me that these males were actively searching for females. The greatly elongated antennomeres provide lots of surface area for sensory pores to detect female pheromones at low concentrations. I’d not seen this before and didn’t know how long it would last—many beetles have narrow windows of activity for mating that can be affected or restricted further by environmental cues such as temperature. I figured I’d better get some photographs on the spot while I could, and this was a smart decision as it wasn’t too long after I took these photos that the males stopped coming to the lights and those that were already there became inactive and no longer held their antennae so impressively splayed.

Polyphylla hammondi

Males cease activity after sunset.

In a recent paper describing a new western species of the genus, La Rue (1998) provided detailed notes on behavior that probably pertain to other sand dune inhabiting species as well. Males were observed to begin flying in late afternoon, making rapid, irregular flights several meters above the sand surface. However, as dusk approached, their flights became less erratic and more purposeful as they flew rapidly upwind and then returned in a slow zig-zag flight (indicative of osmoclinotaxic orientation). Mating occurred after they located a female sitting on the sand and alighted within a few centimeters of her. Several males were attracted to each female, further supporting the use of pheromones by the female to attract males. Males were also attracted abundantly to lights after dusk and ceased activity shortly to several hours after sunset, presumably because females cease releasing pheromone to attract them and burrow back into the sand.

North America’s most recognizable longhorned beetle

One of the more impressive insects that we found during our visit to Sand Hills State Park in south-central Kansas last June was Plectrodera scalator, the cottonwood borer. Large and robust (in fact, the only larger species in the family are the prionid root borers and their kin), their striking checkered pattern of white pubescence on a glossy black body makes them perhaps the most recognizable of all North American longhorned beetles (Linsley & Chemsak 1984). The very robust body of this individual, along with the relatively shorter antennae (only about as long as the body) identify it as a female—males are generally smaller and less robust with the body slightly tapering and the antennae distinctly longer than the body.

Plectrodera scalator

The white coloration on the body of these beetles is not a cuticular pigment (which is rather rare in beetles and is most often associated with species found in white sand habitats, e.g., certain tiger beetles), but instead a result of dense mats of microscopic white setae. The patterns formed by these mats are apparently as unique to each individual as fingerprints are to humans (Yanega 1996), making these beetles at once immediately recognizable as a species yet distinctive as individuals.

Plectrodera scalator

Adults of this species are found most often on cottonwood.

These are said to be common beetles in their range across the eastern two-thirds of the country, especially so in the Great Plains where their favored host, cottonwood (Populus deltoides), is especially abundant. Despite this, I have encountered this species only a handful of times in more than 3o years of searching. I know they’re out there, even in my home state of Missouri where I recorded 154 specimens collected in the state and deposited in various collections (MacRae 1994). It was not until around 2000 that I even saw my first ones (on a cottonwood tree in a homeowner’s yard just across the Mississippi River in Illinois), and in fact this one was actually found by Mary Liz Jameson, who had accompanied us to the field that day. It makes me wonder if their coloration, so strikingly conspicuous when isolated against a clean, blue sky background, might actually afford some type of cryptic protection against the normal backdrop of foliage and branches on which they are normally found—a phenomenon that I call “conspicuous crypsis” and which I have noted for other longhorned beetles (e.g., Acanthocinus nodosus). Perhaps, with this species at least, I have not yet set my search image to notice them.

Plectrodera scalator

Large, robust size and a distinctive checkered pattern of black and white makes these beetles among the most recognizable longhorned beetles in North America.

A suitable ode to Warren Knaus

Last June Jeff Huether and I made a trip out to a system of sand the dunes just south of Medora, Kansas. These dunes have been a popular historical collecting site since the late 1800s, when Warren Knaus first called attention to the area as “an interesting and profitable” locality for collecting insects (Knaus 1897). Knaus was a newspaper publisher in McPherson County, Kansas from 1886–1938, but his true passion was collecting beetles—an activity that took him throughout the Great Plains and Desert Southwest for nearly 50 years and earned him stature as one of Kansas’ most highly regarded coleopterists (Dean 1938). Despite his travels, Knaus remained enamored with the sand hills near his home and eventually published an annotated account of the rarer and more interesting beetles that he had encountered there over the years (Knaus 1926). One of the beetles mentioned in that paper was a “new species of Strigodermella…taken by sweeping in 1923 and 1925″. Those specimens soon became the type series for Strigodermella knausi (now Strigoderma knausi), named such by its describer (Brown 1925) in honor of its collector.

"Medora" Dunes

I suppose it is only fitting, then, that one of the first beetles that we encountered that day was this species. Actually, we couldn’t have missed them if we tried, they were so numerous! At first I assumed they were Strigoderma pygmaea, a species I had seen only once many years ago in Florida. Fortunately, we were in the company of Mary Liz Jameson, Associate Professor of Entomology at Wichita State University and an expert on scarab beetles. Mary Liz informed us of the beetle’s true identity, noting its rarity and relatively restricted distribution and that this was the type locality for the species.

Strigoderma knausi

Strigoderma knausi males were abundant on low vegetation | Sand Hills State Park, Kansas

At first the beetles were merely bycatch in our sweep nets as we looked for more ‘interesting’ beetles (i.e., jewel beetles for me, blister beetles for Jeff, and longhorned beetles for both of us). I tend to have trouble remaining so singularly focused, however, especially when the jewel and longhorned beetles aren’t out in numbers, and before long I found myself observing, and eventually photographing, these diminutive little scarabs. They were especially abundant at the south edge of the dunes, where they were hanging out on grasses and other low vegetation. A closer look revealed that almost every individual was perched in a rather characteristic pose, clinging to the vegetation with the middle and hind legs but extending them so that the beetle was nearly horizontal with the front legs held free and the segments of the antennal club spread widely apart. One can only presume that these were all males and that they were adopting this pose in an attempt to “smell” sex pheromones emitted by the unseen females. Mary Liz mentioned that the females are very rarely seen, and indeed among the nearly 100 specimens examined by Bader (1992) in his revision of the genus was but a single female.

Strigoderma knausi

Almost every individual clung to the vegetation with the front legs free and antennae spread open.

Bader (1992) notes that S. knausi has been taken by sweeping grasses and cotton and taken by light traps in Kansas and Oklahoma with a few records from northern Texas. I mentioned earlier the resemblance of this species to S. pygmaea (Fabricius, 1798), which, like S. knausi, also seems to prefer sandy habitats and can be taken at lights or by sweeping low vegetation (Bader 1992). That species, however, occurs more broadly across the southeastern U.S., being especially common in Florida and along the Atlantic coast as far north as Long Island, New York. The two species can be distinguished by, among other characters, the presence (S. knausi) or absence (S. pygmaea) of a median sulcus (furrow) on the front part of the pronotum (easily seen in the second photo above).

Summer Insect Collecting iRecap

At the beginning of the season I was planning to spend the first week of June collecting insects in southeastern New Mexico. Family issues intervened, however, and left me with a week of vacation time and no plans on how to use it. I’ve never been one to not use vacation time, so I quickly came up with a backup plan—a Friday here and a Monday there to create several 3–4 day weekends. Long weekends may not allow travel to far off and exotic places, but they do allow me to travel a bit further than I would for a regular weekend. I also took advantage of my frequent travel for work to stop off at favorite collecting sites for an evening of blacklighting (much more fun than sitting in a hotel room) or a half-day in the field before getting back home. I always have my big camera with me for serious insect photography when the opportunity arises, but I also take frequent iPhone snapshots to document the “flavor” of my time in the field. In previous years, I’ve collected snapshots from my extended trips into “iReports”, which were later followed by posts featuring subjects that I spent “quality camera time” with (see 2013 western Oklahoma, 2013 Great Basin, and 2014 Great Plains). I’ve decided to do the same thing now, only instead of a single trip this report covers an entire summer. I realize few people have the patience for long-reads; nevertheless, enough readers have told me that they like my trip reports and all of their gory details to make this a worthwhile exercise. If you’re not among them, scan the photos—all of which were taken with a stock iPhone 5S and processed using Photoshop Elements version 11—and you’re done!


Searching for the Ghost Tiger Beetle
Central/Northwest Missouri (12–14 June 2015)

In mid-June my good friend, colleague, and fellow cicindelophile Chris Brown and I followed the Missouri River Valley across the state and and up along its northwestern border to visit previously known and potentially new sites for Ellipsoptera lepida—the Ghost Tiger Beetle. We first saw this lovely white species back in 2000 while visiting some of the large sand deposits laid down in central and east-central Missouri by the 1993 flood. In the years since these sites have become increasingly encroached by forests of eastern cottonwood (Populus deltoides), making them less and less suitable for the beetle (it also remains one of only two tiger beetles known to occur in Missouri that I have not yet photographed). In the meantime several new sand deposits have been laid down in northwestern Missouri by flooding in 2011, so the question has come up whether the beetle has yet occupied these new sites. We started out at a couple of potentially new sites in east-central Missouri (and did not find the beetle), then went to one of two known sites in central Missouri. We did not find the beetle there either, but we did find this eastern hognose snake  (Heterodon platirhinos).

Hognose snakes are well known for their vaired repertoire of defensive behaviors—from flattening of the head and hissing to rolling over and playing dead (a behavior called thanatosis)—the latter behavior often accompanied by bleeding from the mouth and even defecating onto itself. This one, however, was content to simply flatten its head and hiss, its tongue constantly flickering.

The flattened head is an attempt by the snake to make itself appear larger and more imposing.

Standing its ground as tenaciously as it did, I took advantage of the opportunity to close in tight and take a burst series of photos, which I used to create this animated gif of the snake’s constantly flickering tongue.

After an evening of driving to northwest Missouri and a stay in one of our favorite local hotels (eh hem…), we awoke to find the scene below at our first destination.

No tiger beetles there! What to do now. One thing I love about modern times is the ability to pull out the smart phone and scan satellite images of the nearby landscape. Doing this we were able to locate a large sand deposit just to the south and navigate local, often unmarked roads to eventually wind up at a spot where we could access the area on foot. But before we did this we needed gas, and the only gas station for miles was a Sinclair station with a bona fide, original green dinosaur—one of the most potent and iconic corporate symbols ever! I remember these from my childhood, but this is the first one I’ve seen in years.

Rain the night before had made the roads muddy, and it was only with some difficulty that we finally located a way to access the sand deposits we had seen on the satellite images. Even then we needed to hike a half-mile to access the sand plain, but once we got there this is what we saw:

Sand plain deposited 2009

At first we were optimistic—the habitat looked perfect for not only E. lepida but also the more commonly seen Cicindela formosa generosa (Eastern Big Sand Tiger Beetle) and, at least in this area, C. scutellaris lecontei (LeConte’s Tiger Beetle). We saw no adults however, as we searched the plain, and we wondered if the cool, cloudy conditions that lingered from the previous evening’s storms were suppressing adult activity. After awhile, however, we noted that we hadn’t even found evidence of larval burrows, and that is when we began to think that maybe four years wasn’t long enough for populations to establish in such a vast expanse of new habitat. Eventually Chris did find a single E. lepida adult—a nice record but certainly not evidence of a healthy population.

Sand plain deposited 2009

Seemingly perfect habitat, but void of active adults or evidence of larval burrows.

The next sand plain we visited was a little further north at Corning Conservation Area, also in Holt Co. and also laid down by the 2011 flood. Once again we saw no active tiger beetles in the area, and by this point we were convinced that the species were not just inactive but had not yet even colonized the plains. It should be noted that large sand expanses such as these actually are not exactly a natural process, but rather the result of river channeling and the use of levees to protect adjacent farmland. Before such existed, the river existed as an intricate system of braided channels that rarely experienced catastrophic flooding. Nowadays, with the river confined to a single, narrow channel, the river valley doesn’t experience a normal ebb and flow of water. Only when water levels reach such extreme levels in the narrow channel that they breach a levee does the adjacent valley flood, with the area immediately downstream from the levee breach receiving huge amounts of sand and mud scoured from the breach zone. Tiger beetle species adapted to ephemeral sand plain habitats along big rivers probably

Cottonwoods and willows were already colonizing the edge of the plain, and the latter were heavily infested by large blue leaf beetles. As far as I know the only species of Altica in Missouri associated with willow is A. subplicata, although admittedly it is a large, diverse genus and there could be other willow-associates within the state that I am unaware of. The beetles seemed especially fond of the smaller plants (1–3′ in height), while taller plants were relatively untouched.

Despite the heavy adult feeding we could find no larvae on the foliage.

Few other insects were seen. I did see a large, standing, dead cottonwood (Populus deltoides) and checked it out hoping hoping to find a Buprestis confluenta adult or two on its naked trunk (a species I found for the first time last year and still have yet to find in Missouri, although it is known from the state). No such luck, but I did collect a couple of large mordellids off of the tree. Let me say also that there were some interesting other plants in the area…

Wild hemp (Cannabis sativa)

After satisfying ourselves that Corning also was not yet colonized by the tiger beetles, we drove further north into Atchison Co., the northwesternmost county in the state, to check out one more sand plain deposited by the 2011 flood at Nishnabotna Conservation Area. The sand plain at this area was much smaller than the two previous plains we had visited, and it was also far less accessible, requiring a bushwhacking hike through thick vegetation that was quite rank in some areas. Nevertheless, we soldiered on, motivated by the hope that maybe the third time would be a charm and we would find the beetles that we were searching for. The hike was not all bad—eagles were abundant in the area, and in one distant tree we could see a female perched near her nest with two large nestlings sitting in it. The passing storm system and sinking sun combined to create a rainbow that arched gracefully over the tree with the nest, resulting in one of the more memorable visions from the trip.

By the time we got close enough to get a better photograph of the nest the female had departed, but the two nestlings could still be seen sitting in the nest. Sadly, the rather great effort we made to hike to the sand plain was not rewarded with any tiger beetles, and in fact the sand plain was little more than a narrow, already highly vegetated ridge that will probably be completely encroached before the tiger beetles ever find it.

Ellipsoptera lepida was not the only tiger beetle we were hoping to see on the trip. The Sandy Stream Tiger Beetle, E. macra, has also been recorded from this part of the state, and being members of the genus Ellipsoptera both species can be attracted to lights at night. In one last effort to see either of these species, we went to Watson Access on the Nishnabotna River, near its confluence with the Missouri River. Thunder clouds retreating to the east were illuminated by the low hanging sun to the west, creating spectacular views in both directions. Unfortunately, the insect collecting at the blacklights after sunset was not near as interesting as the sky views that preceded it.

The next day we had to start making our way back to St. Louis. But while we were in the area we decided to check on the status of one of Missouri’s rarest tiger beetlesParvindela celeripes (formerly Cylindera celeripes)—the Swift Tiger Beetle. Not known to occur in Missouri until 2010, this tiny, flightless species is apparently restricted in the state to just three small remnants of loess hilltop prairie in Atchison and Holt Counties. We were close to one of these—Brickyard Hill Conservation Area (where Chris and I first discovered the beetles) so stopped by to see if adults were active and how abundant they were. To our great surprise, we found adults active almost immediately upon entering the site, and even more pleasantly surprising the adults were found not just in the two small areas of the remnant where we had seen them before but also in the altered pasture (planted with brome for forage) on the hillside below the remnant (foreground in photo below). This was significant in our minds, as it was the very first time we have observed this beetle in substantially altered habitat. The beetle was observed in relatively good numbers as well, bolstering our hopes that the beetles were capabale of persisting in these small areas and possibly utilized altered pastureland adjacent to the remnants.

As we made our way back towards St. Louis, there was one more site created by the 1993 flood where we observed E. lepida in the early 2000s that we wanted to check out and see how the beetle was doing. In the years since we first came to Overton Bottoms, much of its perimeter has converted to cottonwood forest; however, a large central plain with open sand exposures and bunch grasses persists—presumably providing acceptable habitat for the species. Chris had seen a few beetles here in a brief visit last summer, but this time we saw no beetles despite a rather thorough search of the central plain. It seemed untenable to think that the beetles were no longer present, and we eventually decided (hoped) that the season was still too young (E. lepida is a summer species, and the season, to this point, had been rather cool and wet). The photos below show what the central plain looks like—both from the human (first photo) and the beetle (second photo) perspective. I resolved to return later in the month to see if our hunch was correct.

It doesn’t happen often, but every now and then I get caught by rain while out in the field, and this time we got caught by a rather ominous thunderstorm. The rain didn’t really become too heavy until shortly before we reached the car, but the lightning was a constant concern that made bushwhacking back more than a mile through thick brush one of the more unnerving experiences that I’ve had to date.


Trying for Prionus—part 1
South-central Kansas (26–29 June 2015)

Last summer Jeff Huether and I traveled to several locations in eastern Colorado and New Mexico and western Oklahoma to find several Great Plains species of longhorned beetles in the genus Prionus using recently developed lures impregnated with prionic acid—a principal sex pheromone component for the genus. These lures are extraordinarily attractive to males of all species in the genus, and on that trip we managed to attract P. integerP. fissicornis, and P. heroicus and progress further in our eventual goal to collect all of the species in the genus for an eventual molecular phylogenetic analysis. One species that remains uncollected by pheromones (or any other method) is P. simplex, known only from the type specimen labeled simply “Ks.” A number of Prionus species in the Great Plains are associated with sand dune habitats, so we had the idea that maybe P. simplex could be found at the dunes near Medora—a popular historical collecting site, especially with the help of prionic acid lures. Perhaps a long shot, but there’s only one way to find out, so we contacted scarab specialist Mary Liz Jameson at Wichita State University, who graciously hosted Jeff, his son Mark Huether, and I for a day in the field at Sand Hills State Park. We didn’t expect Prionus to be active until dusk, during which time we planned to place lure-baited pitfall traps and also setup blacklights as another method for attracting the adult males (females don’t fly). Until then, we occupied ourselves with some day collecting—always interesting in dune habitats because of the unique sand-adapted flora and the often unusual insects associated with them.

"Medora" Dunes

Sand Hills State Park (“Medora Dunes”), Kansas

Milkweeds (genus Asclepias) are a favorite of mine, and I was stunned to see a yellow-flowered form of butterfly milkweed (A. tuberosus). Eventually I would see plants with flowers ranging from yellow to light orange to the more familiar dark orange that I know from southern Missouri. I checked the plants whenever I saw them for the presence of milkweed beetles, longhorned beetles in the genus Tetraopes (in Missouri the diminutive T. quinquemaculatus is most often associated with this plant), but saw none.

Asclepias tuberosus "yellow form"

In the drier areas of the dunes, however, we began to see another milkweed that I recognized as sand milkweed (A. arenicola). I mentioned to Jeff and Mary Liz that a much rarer species of milkweed beetle, T. pilosus, was associated with this plant and to be on the lookout for it (I had found a single adult on this plant at a dune in western Oklahoma a few years back). Both the beetle and the plant are restricted to the Quaternary sandhills of the midwestern U.S., and within minutes of me telling them to be on the alert we found the first adult! During the course of the afternoon we found the species to be quite common in the area, always in association with A. arenicola, and I was happy to finally have a nice series of these beetles for my collection.

Tetraopes pilosus

Two Sandhills specialties—Tetraopes pilosus on Asclepias arenaria

Milkweed beetles weren’t the only insects associated with sand milkweed in the area—on several plants we saw Monarch butterfly larvae, some nearing completion of the larval stage as the one shown in the photo below. Monarchs have been in the news quite a bit lately as their overwintering populations show declines in recent years for reasons that are not fully understood but may be related to recent droughts diminishing availability of nectaring plants for migrating adults and reduction of available food plants as agricultural lands in the U.S. become increasingly efficient.

We found some other interesting insects such as the spectacular Plectrodera scalator, cottonwood borer, and the southern Great Plains specialty scarab, Strigoderma knausi, both of which I took the time to photograph with the big camera—separate posts on those species will appear in the future. Sadly, no Prionus came to either our lures or our lights that evening, but some interesting other insects were seen during the day and even at the lights despite unseasonably cool temperatures and a bright moon. I’ll post photographs of these insects, taken with the “big” camera, in the coming weeks. In the meantime, my thanks to Mary Liz for hosting us—I look forward to our next chance to spend some time in the field together.

The following day, Adam James Hefel—at the time a graduate student at Wichita State University—and I traveled northwest of Wichita to Quivira National Wildlife Refuge. Adam has recently become interested in tiger beetles and had observed several interesting species on the margins of the salt marshes at Quivira. Several of these species were on my “still to photograph” list (and one even on my “still to see” list), so I was happy to have access to some local knowledge to help me

Salt marsh

Quivira NWR – salt marsh habitat for halophilic tiger beetles

The saline flats of the central U.S. are hyperdiverse for tiger beetles. Adam has seen six species in the saling flats of Quivira, including the saline specialists Cicindela fulgida, C. wllistoni, Ellipsoptera nevadica knausi, Eunota togata, and E. circumpicta johnsonii (formerly Habroscelimorpha) (both red and green forms) and the ubiquitous Cicindelidia punctulata. We managed to find all of these except C. willistoni, which is a spring/fall species—unusual for a saline specialist, but the extreme heat of the day made them exceedingly difficult to approach (and virtually impossible to photograph).

Salt marsh

Tiger beetles are found most often in alkaline flats with sparse vegetation

The wide open central flats are devoid of not only vegetation but tiger beetles (and life in general!).

Ever fascinated by the diversity of milkweeds to be found in the central U.S., an unfamiliar Asclepias growing in the higher, drier areas around a salt marsh caught my attention. Of course, I checked them for milkweed beetles and quickly found a number of Tetraopes tetraophthalmus individuals. John Oliver kindly identified the milkweed from my photos as Asclepias speciosa (showy milkweed), which does not occur in Missouri (hence the reason I was not familiar with it) but that gets common in the Great Plains and foothills of the Rocky Mountain.

The specific epithet “specioosa” refers to the large, showy flowers.

Tiger beetles were not the only wildlife encountered on the saline flats. Killdeer and western snowy plover adults were abundant in the area, and we found this next with eggs along the lightly vegetated edge of a saline flat around Big Salt Marsh. Cheryl Miller suggested they are probably plover eggs, since killdeer don’t usually scrape out a cup or put debris around the eggs, while snowy plovers are known to nest on or near salt flats and frequently surround their eggs with twigs, small bones or other debris.

During the drive into the refuge, I noted several stands of large cottonwood (Populus deltoides), many of which were half- or completely dead. To some, these trees may be just ugly, half-dead trees. For me, however, they offer an opportunity to look for the gorgeous and rarely encountered Buprestis confluens, a species which I found for the first time just last year (not too far from hear in north-central Oklahoma). After getting our fill of tiger beetles, we drove to a parking lot surrounded by some of these trees, and even before I got out of the car I could see an adult B. confluens sitting on the trunk of a large, dead tree at the edge of the parking lot! I quickly secured the specimen, then spotted the half-dead tree in the photo below and walked towards it to look for more. I did not see any adults sitting on the trunk, but what I did see was truly incredible—two adults just beginning to emerge from the trunk! Waiting for one of the adults to emerge naturally (we “helped” the other one along) and photographing the sequence would occupy the next hour, but what an experience (and, of course, photos to come in a separate post).

After a break from the heat and something to eat in the nearest town (20 miles away), I returned to the cottonwoods, broke out the hatchet, and began chopping. Cottonwood is an amazingly soft wood compared to hardwoods such as oak and hickory, but dead cottonwood is still tough, and only after much effort did I manage to chop out two pupae (one of which later successfully emerged as an adult) and two unemerged adults, resulting in a nice, if still rather small, series of a species that until last year was not represented in my collection and until this time by only a single specimen.

With the setting sun illuminating distant thunderclouds, I returned to the salt marshes to setup blacklights for the evening in hopes of attracting some of the tiger beetles that we had seen earlier in the day—not in attempt to collect more specimens, but rather to take advantage of their attraction to the lights and reduced skittishness in the cool, night air in an attempt to photograph them (I already had live specimens for studio photographs if necessary, but I prefer actual field photographs whenever possible). Eunota togata was not attracted to the lights, but both E. nevadica knausi and E. circumpicta johnsonii came to the lights in numbers (both red and green forms of the latter), and I succeeded in getting some real nice photographs as a result.

On the way back home, and again with the sun dropping close to the horizon, I stopped by Overton Bottoms again to look for Ellipsoptera lepida. Chris and I hadn’t see it here two weeks ago, and I was thinking (hoping) that it might have still a bit early in the season. This time I found them, and although they were not numerous and were apparently confined to the southernmost exposures of the central sand plain, they were still plentiful enough to allow me to get the field shots that I’ve wanted of this species for so long (and providing fodder for yet another future post). This species never seems to be encountered in great numbers, and although I have seen them on a number of occasions it always amazes me just how difficult they are to see!

Tryin’ for Prionus—part 2
South-central Kansas (11–12 July 2015)

Although our long-shot effort for Prionus simplex at the dunes near Medora, Kansas didn’t pan out, another species we hoped to see was P. debilis—a rather uncommonly collected species that occurs in the tallgrass prairies of the eastern Great Plains and, to our knowledge, had not yet been demonstrated to be attracted to prionic acid. I’d only seen this species once myself, some 30 years ago when I collected four males at lights near the southwestern edge of Missouri. As it happens, longtime cerambycid collector Dan Heffern grew up in P. debilis-land near Yates Center—not too far from where we were just a few weeks ago. When I mentioned my search for the species, he told me how commonly he used to see it around his home—especially around the 4th of July—and put me in contact with a friend who still lives in the area and has several tallgrass prairie remnants on his land. I made arrangements to visit the following weekend, and with prionic acid impregnated lures in the cooler and blacklights and sheets in the cargo area I set off. As I passed south through eastern Kansas I began to see nice tallgrass prairie remnants about 20 miles from my destination, so I took a chance and set a trap as a backup in case things didn’t pan out near Yates Center.

Things did pan out, however, although for a long time it did not appear they would. Dan’s friend kept me company while I placed a couple of traps and setup the blacklights, and for a couple of hours after sunset no beetles were seen (although we did enjoy good beer and better conversation). Just when I was ready to throw in the towel I saw a male crawling on the ground near one of the lights, and over the course of the next hour I found nearly a dozen males crawling on the ground in the general area around the lights but never actually at the lights. Interestingly, no males were actually seen in flight, nor were any attracted to the trap placed near one of the lights; however, after I took down the lights and checked the other trap there were five males in it. This likely represents the first demonstration of attraction to prionic acid by males P. debilis. I brought a couple of live males home for photography, taking this iPhone shot of a sleeping beetle in the meantime.

One the way back home the next morning, success already “in the bag”, I stopped to check the trap I had placed the previous day. Filled with anticipation as I approached the trap, I was elated to find 21 males in the trap!

The male antennae of this and other Prionus species show numerous adaptations that are all designed to maximize the ability to detect sex pheromones emitted into the air by females. They are both hyper-segmented and flabellate, providing maximum surface area for poriferous areas filled with chemical receptors. Larval habits for this species remain unknown, but Lingafelter (2007) states “Larvae may feed in living roots of primarily Quercus and Castanea, but also Vitis, Pyrus, and Zea mays.” I am not sure of the source of this information and don’t really believe it, either, as I think it much more likely that they feed on roots of bunch grasses such as bluestems (Andropogon spp.) and other grass species common in the tallgrass prairies.

Before reaching St. Louis, I decided to stop off at the last two known sites for Missouri’s endangered (possibly extirpated), disjunct, all-blue population of Eunota circumpicta johnsonii (Johnson’s Tiger Beetle). This didn’t go well—I first tried Blue Lick Conservation Area in Cooper County, where Chris Brown and I made the last known sighting of this beetle in the state 12 years ago at a salt spring about 500 yards further down the road in the photo below. I’m unsure what adaptations adults and larvae may have for surviving prolonged flooding, but it certainly cannot be helpful for the beetle. I then visited nearby Boone’s Lick State Historic Site in Howard County, and while the site was not flooded the two small areas where salt springs were located during our survey were even more heavily encroached by vegetation than before. Not only were no beetles seen, there did not even seem to be the slightest possibility that beetles could occur there. I keep hoping that the beetle will, someday, be seen again, but in reality I think I am just having trouble accepting the fact that I may have actually witnessed the extirpation of this incredibly beautiful and unusual population of beetles.

Chillin’ after work
Sand Prairie – Scrub Oak Preserve, central Illinois (15 July 2015)

By the time mid-July rolls along, temperatures are not the only thing heating up. My travel for work also reaches a fever pitch as I begin traveling to research plots in Illinois and Tennessee every  two weeks. It takes three days to make the +1,000-mile round trip, which means that I have two nights and an occasional afternoon stop to collect insects—much more fun than checking into hotel right after work, eating dinner at Applebee’s, and spending the evening switching back and forth between FOX and MSNBC to see who can make the most outrageous statement because IFC just isn’t offered. One of my favorite spots along this route to set up a blacklight is Sand Prairie – Scrub Oak Preserve in Mason County, Illinois. Nothing too spectacular showed up at the lights there this season, but as they say a bad day (or night) of bug collecting is better than a good day of just about anything else.

Calling all insects—the blacklight awaits you!

On this particular night a number of hawk moths (family Sphingidae) came to the lights, among the prettier of which included this Paonias excaecata (blinded sphinx) (kindly identified by Robert Velten).

Pinewoods Lake, southeast Missouri (28 July 2015)

Another species of Prionus that I hadn’t seen for many years was P. pocularis, a species found in the pineywoods across the southeastern U.S. and, thus, reaching its northwestern distributional limits in the shortleaf pine (Pinus echinata) forests of the Ozark Highlands in southern Missouri. Like P. debilis, I had only seen this species once before—two males at a blacklight at Pinewoods Lake National Forest Recreation Area in Carter County many years ago. Unlike P. debilis, however, these were seen later in summer, as were a few other specimens known from the state. That being the case, I decided to try the prionic acid lures at Pinewoods Lake while traveling back up from Tennessee. I arrived at the lake shortly before sunset and, after getting the traps put out and the lights setup, had the chance to look out over the lake and its surrounding forests where I had collected so many insects back in the 1980s as a young, eager, budding coleopterist.

Quite some time passed and no Prionus beetles were seen at the light or in the trap (but several other longhorned beetles did occur). Recalling my experience with P. debilis in Kansas a few weeks earlier, I remained hopeful, and eventually my optimism was rewarded when I found this single male floating in the trap’s ethanol preservative. Curiously, it would be the only male seen that night, although several individuals of the related and much more common P. imbricornis were attracted to the prionic acid lures.

Several other insects did come to the blacklights, among the more photogenic being this underwing moth (genus Catacola, family Noctuidae) identified by Mathew L. Brust as Catocala neogama.

Even more photogenic than underwings are royal moths (family Saturniidae), including this imperial moth, Eacles imperialis.

Among the longhorned beetles I mentioned that did come to the lights was this Orthosoma brunneum (brown prionid). This species is closely related to prionid beetles (both are in the subfamily Prioninae). However, it is not a member of the genus Prionus, and, thus, is not attracted to prionic acid. It is perhaps no coincidence that males of this species do not exhibit the hypersegmentation and flabellate modifications of their antennae possessed by males in the genus Prionus, though they may still rely on sex pheromones for locating females.

Even spiders were coming to the blacklights, perhaps attracted not by the light itself but by the ready availability of potential prey.

Cicadamania!
White River Hills region, southwest Missouri (1–2 August 2015)

Although I had succeeded in finding Prionus pocularis earlier in the week at Pinewoods Lake, I wasn’t satisfied with having found just a single individual. I had nothing on the calendar the following weekend, so I decided to make a run down to one of my favorite areas in all of Missouri—the White River Hills of extreme southwest Missouri. The only other record of the species in Missouri is from that area, with its abundance of shortleaf pine forests (the species breeds in decadent pines), and I though how nice it would be to find more individuals in a part of the state that I love so much. The plan was to drive down, set a prionic acid trap or two once I got into the pine forests of the area, and then find a good spot to setup some blacklights with one more prionic acid trap that I could monitor. The plan was executed perfectly, and I ended up setting up the lights on a ridge just south of Roaring River State Park; however, the beetles never came. Nevertheless, like I said earlier a bad day/night of bug collecting is still better than just about anything else, and there was plenty at and near the lights to keep the night interesting. Once was this tiny walkingstick nymph that I found hanging out at the tip of a blade of grass. I was intrigued by the rather peculiar position adopted by the resting animal, with its forelegs and antennae extended straight out in front of the body with their tips resting on the grass blade.

One thing I love about blacklighting for insects is the sounds of the night—katydids fill the black night with raspy calls while Whip-Poor-Wills and their country cousins the Poor-Will’s-Widows hoot and cluck in the distance.

As I was photographing the walkingstick, I felt something crawling on my neck. After many years of doing this, I’ve learned not to freak out and slap wildly at something crawling on my neck, because 1) more often than not it is something interesting and 2) even if it isn’t particularly interesting it’s almost never capable of biting or stinging. Still, I don’t want to just grab it unseen or pin it against my neck—instead I kind of “scoop” it away with my fingers and toss it onto the ground beside me in one swift, assertive movement. This night’s mystery neck crawler was about as interesting as they get—Dynastes tityus (eastern Hercules beetle), the largest beetle in eastern North America. This one is a female by virtue of its lack of any horns on the head and pronotum.

After pulling the lights down for the night, I drove to Mincy Conservation Area, one of the many dolomite glades in the area in the next county over and one that I had not visited for some time. There are no hotels in the area, and my bones are a little too old to be sleeping on the ground, so I just pulled into the campground, took off my shoes, changed into PJs, and laid the driver’s seat all the way back for a surprisingly comfortable night’s sleep. My frugalness would have its reward, although I did not know it until I awoke early the next morning to a hauntingly beautiful fog. I’d never seen the glades in such manner—so serene. I knew the rising sun would quickly burn off the fog and and the moment would be lost if I didn’t act quickly, so I grabbed both big camera and iPhone and, put on some shoes (didn’t bother with changing out of my PJs), and walked the glade taking as many photos as I could. While the quality of the iPhone snaps doesn’t compare with those taken with the big camera, they nevertheless convey the quiet beauty of the glade.

Heading back to my car as temperatures began to rise quickly, I was struck by the cacophony of cicadas that were already getting into high gear with their droning buzz calls. As I passed underneath one particular tree I noticed the song was coming from a branch very near my head. I like cicadas, but I was there to look for the spectacular Plinthocoelium suaveolens (bumelia borer), a glade species associated with gum bumelia (Sideroxylon lanuginosum). Had it been the song of a “normal” cicada like Neotibicen lyricen (lyric cicada) or N. pruinosus (scissor grinder cicada) I would have paid it no mind. It was, instead, unfamiliar and distinctive, and when I searched the branches above me I recognized the beautiful insect responsible for the call as Neotibicen superbus (superb cicada), a southwest Missouri specialty—sumptuous lime-green above and bright white pruinose beneath. I had not seen this spectacular species since the mid 1980s (most of my visits to the area have been in the spring or the fall rather than high summer), so I spent the next couple of hours attempting to photograph an individual in situ with the big camera. This is much, much easier said than done—the bulging eyes of cicadas give them exceptional vision, and they are very skittish and quick to take flight. I knew I had the iPhone photo shown below if all else failed, and for some time every individual I tried to approach ended up fluttering off with a screech before I could even compose a shot, much less press the shutter. Persistence paid off, however, and I eventually succeeded in locating, approaching, and photographing an unusually calm female resting at chest height on the trunk of a persimmon tree. Along the way I checked the gum bumelia trees hoping to spot one of the beautiful longhorned beetles associated with that tree, but none were seen.

It was already high noon by the time I finished up at the Mincy glades, so I began to retrace my steps to check the prionic acid traps that I had set out the day before. Along the way I stopped by Chute Ridge Glade Natural Area in Roaring River State Park, another place where I have seen bumelia borers, so I stopped to try my luck there before continuing on to pick up the traps. Again, none were seen, but in addition to numerous individuals of N. superbus I found another species of cicada, still undetermined by more robust and nearly blackish and with a throatier call that sounding a bit like a machine gun (or table saw hitting a nail!). Despite the lack of bumelia borers, I enjoyed my time on the glade immensely and eventually had to call it quits if I was to get to all of my traps before nightfall.

Still more chillin’ after work
Pinewoods Lake, southeast Missouri (11 August 2015)

Two attempts at Prionus pocularis in the past two weeks had netted me but a single specimen—this species was becoming my summer nemesis. So when I found myself back in Tennessee for field trial work and the timing still right I decided to spend the evening at Pinewoods Lake once again before heading back to St. Louis and see if the third time would be a charm. I found a new restaurant in the tiny nearby town of Ellsinore, and the dinner special that evening was fried catfish—hoo boy! My belly was in a good place after that, filling me with optimism that I would have success tonight. I got to the lake at dusk, quick setup the blacklights and put the prionic acid traps in place, and waited for the bugs to come in.

Pinewoods Lake at dusk, again!

The evening’s first visitor to the lights was a parandrine cerambycid—Neandra brunnea. Believe it or not, this was the first time I have ever seen the species alive (once before finding a dead specimen in a Japanese beetle trap waaaay back in the mid-1980s!)—a pretty nice find. In fact, Pinewoods Lake produced a number of good finds during those days back in the 1980s when I was collecting here regularly—longhorned beetles such as Acanthocinus nodosus, Enaphalodes hispicornis, and the aforementioned Prionus pocularis, male Lucanus elaphus stage beetles, the jewel beetle Dicerca pugionata on ninebark in the draws, and the seldom seen tiger beetle Apterodela unipunctata (formerly Cylindera unipunctata), just to name a few.

Seeing N. brunnea and the prospects of collecting P. pocularis weren’t the only things putting me in a good mood…

Blacklighting w/ beer

Blacklighting is better with beer!

My optimism, unfortunately, would eventually prove to be unfounded, as not only did P. pocularis never show up—either at the blacklights or the prionic acid traps, no other beetles showed up as well, longhorned or otherwise. When that happens, I have no choice but to start paying attention to other insects that show up at the lights. It was slim pickings on this night for some reason, making this already striking moth identified by Alex Harman as Panthea furcilla  (tufted white pine caterpillar or eastern panthea) in the family Noctuidae stand out even more so.

While walking between the blacklights and the prionic acid traps, something suspended between two trees caught my eye. I recognized it quickly as some type of orb weaver spider (family Araneidae), but I couldn’t exactly figure out exactly what was going on until I took a closer look and saw that there were actually two spiders! I’d never seen orb weaver courtship before, so I excitedly took a few quick shots with the iPhone and then hurried back to the car to get the big camera.

Neoscona sp. courtship

Be very, very careful boy!

Sadly, the male had already departed by the time I got back, so the quick iPhone photos I took are the only record I have of that encounter. Still, I got some good photos of just the female with the big camera, along with the quicker, dirtier iPhone shots—one of which is shown below. According to Eric Eaton these are likely a species in the genus Neoscona.

Checking out a fen
Coonville Creek Natural Area, southeast Missouri (3 September 2015)

On yet another trip back to St. Louis from Tennessee, I made a spur-of-the-moment decision to visit Coonville Creek Natural Area in St. Francois State Park, an area I hadn’t seen in nearly 30 years and the outstanding feature being the calcareous wet meadow, or “fen”, that dominates the upper reaches of the creek drainage. Fen soils are constantly saturated, a result of groundwater from surrounding hills percolating through porous dolomite bedrock before hitting a resistant layer (in this case, sandstone) and seeping out onto the lower slopes. Constantly saturated soils and occasional fires (at least historically) have kept the fen open and treeless, with the cool groundwater allowing “glacial relicts” (i.e., plants common when glaciers covered the area) to persist.

I saw a few Cicindela splendida (Splendid Tiger Beetles) on the rocky, clay 2-track leading to the area—a sure sign that fall was just around the corner, a female cicada on herbaceous vegetation in the fen (small, I think it’s not a species of Neotibicen), and a huge, fecund black and yellow garden spider (Argiope aurantia)—I love seeing the latter at this time of year when they have grown to their largest and the females are full of eggs. In reality, however, this visit turned into more of a botanical than an insect collecting experience. Insect activity in general was low, and my attention drifted instead to the diversity of wildflowers that were present on the fen—most new to me. False dragonhead (Physostegia virginiana), great blue lobelia (Lobelia siphilitica), and Spiranthes lacera (slender ladies’-tresses orchid)—its tiny white blossoms spiraling up the leafless spike were the most interesting, resulting in lots of time spent looking at them through the big camera.

The always exciting amorpha borer
Otter Slough Conservation Area, southeast Missouri (23 September 2015)

As the dog-days of summer gave way to bright, blue skies and crisp, fall air, a distinctive insect fauna takes advantage of the explosion of goldenrod that blooms across a landscape morphing from shades of green to orange, yellow, and tawny. Many of these insects are widespread and super-abundant—soldier beetles, tachinid flies, bumble and honey bees, and scoliid, tiphiid, and vespid wasps are among the most conspicuous. Megacyllene robiniae, longhorned beetles commonly called locust borers  are also common on goldenrod during fall, but much less common is a closely related species that breeds in false indigo bush (Amorpha fruticosa)—Megacyllene decora, or the amorpha borer. I’ve seen this species several times, yet uncommonly enough that I still target it when I get the chance. One such place is Otter Slough Conservation Area—yet another interesting place along the way between Tennessee and St. Louis. On one of my final trips back this way I stopped by to see if these spectacular beetles would be out. My attention was first caught by egrets congregating in a mud flat exposed by recent dry weather. However, they were not what I was looking for.

There is no shortage of interesting insects to look at as I begin scanning the goldenrod flowers growing along the roadsides and around the edges of the shallow pools managed for fishing and shore birds. A fat, female Stagmomantis carolina (Carolina mantis) sat on one of the first inflorescences that I checked, but she also was not what I was looking for.

After a bit of searching, I found what I was looking for! Over the course of the next two hours (all the time I had left before sundown) I would a total of three adults on goldenrod flowers at three disparate locations within the area—again not very many, making those that I did see a real treat.

As dusk fell over the area, insects began bedding down for the night. I was lucky to find the last amorpha borer in the dwindling light as it bedded down next to a bumblebee—perhaps the likely model for the beetle apparent mimetic coloration.

The sun sinking over the horizon behind the wetlands put an end to the collecting, not only for the day but for the season, at least here in Missouri and surrounding states. It would not be the final day of collecting for me, however, as I managed to scrape together some free time amidst my hectic travel schedule and spend a week in eastern Texas for the Annual Fall Tiger Beetle Hunt. I’ll save that trip for another report and close this one out here, but be on the lookout for higher quality photos over the coming months of the really interesting insects that I encountered over this past season. Let me also say that if you’re still reading at this point, you have my deepest admiration for having the persistence to wade through all 8,376 of the words contained within this post!

Euhagena nebraskae in Kansas

Gypsum Hills region of south-central Kansas (Barber Co.)

One of my favorite destinations for insect collecting is the Gypsum Hills region in Barber County of south-central Kansas.  I first went there in May 1986 after seeing a diverse selection of more typically Texan Buprestidae that J. Richard Heitzman, an iconic lepidopterist in the Kansas City area and author of Butterflies & Moths of Missouri, had collected there on soapberry (Sapindus saponaria).  I had my own success with Buprestidae as well during that trip, but in recent years I have returned to Barber County several times during the fall to look for one of North America’s most beautiful tiger beetles, Cicindela pulchra (Beautiful Tiger Beetle).  This species had been recorded in the area by the well-known cicindelophiles Ron Huber and Dave Brzoska, who suggested that I look in the red clay hills just west of Medicine Lodge.  My first trip to look for this beetle in 2004 was unsuccessful, and I suspect the early September timing of my trip may have been a tad too early.  I returned again in 2005, this time in early October and also enlisting the help of local entomologist “Beetle Bill” Smith, who knew of a population on private land near his home in Hardtner (south of Medicine Lodge).  Although at first it looked like success might again elude me, in the end I saw a robust population of these spectacular beetles and published an account of that marvelous experience (MacRae 2006).

As with so many of the things that I have seen over the years, they came before my interest in photography, and I now find myself wanting to re-find some of the more spectacular insects that I’ve previously found so that I can properly photograph them.  Such is the case with C. pulchra, so in October of last year I returned to Barber County in hopes of seeing this species armed not only with an aerial net, but also a Canon 50D.  Sadly, this would not come to pass – the same sudden cold snap that dashed my hopes of finding this species in nearby Woodward/Major Counties, Oklahoma would keep any tiger beetle activity to a bare minimum the following day in Barber County as well.  Despite bright sunny skies, I would see only two tiger beetles the entire day, both representing the dreadfully ubiquitous Cicindela punctulata (Punctured Tiger Beetle).  Not all insect activity, however, was squelched, and after scanning the red soils for an hour or so without seeing the object of my desire I began to notice some of these other not-so-temperature-finicky species.  One of the more magnificent of these is shown in the photo below — Euhagena nebraskae in the family Sesiidae (cess-EYE-id-ee) (formerly Aegeriidae).

Euhagena nebraskae

Euhagena nebraskae (Lepidoptera: Sesiidae)

Although I wasn’t sure of the species at first, I recognized it immediately as a clearwing moth.  I had an interest in this family of moths for a time in my early days as a field entomologist with the Missouri Department of Agriculture.  Many species are important pests of woody plants in orchard and ornamental landscapes, and it was during that time that synthetic pheromones became widely used for monitoring purposes.  I often walked around with a pheromone tag pinned to my bag to attract the male moths — it was fun watching people seeing these moths “buzzing” me and thinking I was under attack by the wasps that they so effectively mimic (despite my calmness in these situations, I still found it hard to actually grab one from the air with my hand – so convincing is their mimicry).

Euhagena nebraskae is one of two species in the genus in North America, both of which develop as larvae in the roots of plants in the evening primrose family (Onagraceae) (Eichlin and Duckworth 1988).  In fact, I had seen its congener — E. emphytiformis — many times in the 1980s in pheromone traps that I used to place in the glades of Jefferson County just south of St. Louis, where it presumably breeds in one or both of two Oenetherea species growing there (O. gaura and O. macrocarpa).  Euhagena nebraskae is a more western species that does not occur in Missouri, occurring instead across the Great Plains west to California and from southern Alberta and Saskatchewan south to Mexico.  It is likely that many entomologists never see this species, as adults are active only during late fall.  Thus, its perception as an uncommon species may be an artifact of its late seasonality. 

I thought it odd that nearly every individual that I saw was sitting on the ground rather than perched higher on a plant.  At first I wondered if the cold temperatures were a reason for this, perhaps causing the moths to seek out the ground as a source of radiant heat.  This seems doubtful, however, since females always seemed to be “calling” – their tufted abdominal tips raised in the air with the scales spread apart, apparently releasing pheromone.  I was fortunate to find this mating pair, which shows nicely the rather high degree of sexual dimorphism seen in these moths.  Note the much more highly bipectinate antennae of the male (pectinate = resembling a comb, bipectinate = ‘teeth’ on both sides of the main stem) versus the simple antennae of the female — males use their antennae for detecting female pheromones, and the bipectinate form presumably provides greater surface area for placement of sensory pores. Note also the male’s smaller size, “hairier” head and thorax, and greater amount of white coloration on the abdomen and wings.  Engelhardt (1946) supposed that the excessive hairiness of adult Euhagena species was an adaptation to their late-season emergence (principally during October and sometimes as late as November), a time when frosty nights prevail in their high-elevation haunts.
