The Webster Groves Nature Study Society (WGNSS) Entomology Group began its final outing of the 2025 field season when eight participants (Chris Brown, Nathalie de Rocquigny, “Ozark Bill” Duncan, Jack Hambene, Pete Kozich, Ted “BugMan” MacRae, Lisa Meihls, and David Seidensticker) met up in the parking lot at Hughes Mountain Natural Area. Tucked into the southeastern corner of Washington Co., this gem of a natural area features 1.5 billion year old Precambrian outcrops that are among the oldest continuously exposed rocks in North America. Once molten as a result of volcanic activity associated with the St. Francois Mountains, the now hardened and weather-resistant rhyolite that formed after it cooled lies still exposed at the summit and surrounding areas. To the geologist, the polygonal columnar pattern of cracking at the summit—resulting in a unique formation called the “Devil’s Honeycomb”—might be the area’s most interesting feature. To the botanist, the xeric grasslands that formed on the surrounding exposures—i .e., “igneous glades”—might instead take this honor. To the entomologist, however, the unique fauna of insects associated with this interesting natural community earns top billing.

On two previous visits, the group has been fortunate to see one of Missouri’s rarest and most beautiful longhorned beetles—Tragidion coquus. Velvety black with vivid orange elytra, this charismatic species is usually seen during fall, and we hoped to be fortunate enough to see it again. Two species of fall tiger beetles—Cicindela limbalis (claybank tiger beetle) and Cicindela splendida (splendid tiger beetle), both colored iridescent green and brick red—were additional possibilities. A clear consensus quickly became apparent, however, when most participants voiced a desire to see Trimerotropis saxatilis—the famously and colorfully cryptic lichen grasshopper! It didn’t take long to see the first ones as soon as we began reaching the swathes of exposed rhyolite with their coverings of green and black lichens. Sitting motionless on the lichen-encrusted rocks, the grasshoppers were almost impossible to see, so perfectly colored and patterned was their camouflage.
The abundance of lichen grasshoppers on the glades was somewhat expected, but what was not was the diversity of other grasshoppers also present at the margins of the glades and in the surrounding dry woodlands. Four such species were documented, including Hippiscus ocelete (wrinkled grasshopper), Melanoplus ponderosus (ponderous spur-throat grasshopper), Melanoplus rusticus (obovate-winged grasshopper), and Spharagemon bolli (Boll’s grasshopper)—all possessing their own forms of cryptic coloration that made relocating them after they jumped difficult.
Two non-grasshopper orthopterans as well were found—several Scudderia furcata (fork-tailed bush katydid), ranging from green to tan to almost pinkish(!), were seen in the glades and woodlands, and an unusually cooperative Ceuthophilus sp. cave cricket (family Rhaphidophoridae) was also seen.
Scudderia furcata (fork-tailed bush katydid—family Tettigoniidae).
The group fanned out across the glades as they worked their way up towards the summit. Of special interest were flowers that might host pollinating insects (and possibly even T. coquus). Few flowers would be found, however—a consequence of abnormally dry conditions since late July, and we found ourselves looking for other targets. Ted managed to photograph a beautiful red-marked variegated meadowhawk dragonfly (Sympetrum corruptum), while David “captured” (through the viewfinder) a male black swallowtail butterfly (Papilio polyxenes).
Eventually the group reached the summit, where the “Devil’s Honeycomb” and a spectacular vista awaited us. An unexpected feature at the summit was white splotches on the tops of many of the projecting columns of rock, which the group surmised to indicate use of the summit as a roosting site by turkey vultures.

The group lingered to take in the crisp air, blue skies, and spectacular view created by 1200’ of elevation before turning back to begin the descent back down the mountain.
Buford Mountain (2nd highest point in Missouri) in the distance.
Descending the mountain, however, did not mean an end of things to see. Even before getting off the summit, Lisa noticed Chelinidea vittiger (cactus leaffooted bug) on pads of Opuntia cespitosa (eastern prickly pear). This species feeds and develops almost exclusively on the pads, fruits, and young growth of prickly pear cacti (Opuntia spp.), thus, its range coincides with the distribution of these cacti.
Further down the mountain, another “variegated” species was seen—this time a variegated fritillary (Euptoieta claudia) butterfly. This well-worn individual was only the third butterfly species seen on the day, the aforementioned black swallowtail and a particularly fresh common buckeye (Junonia coenia) being the other two. This one was probably making its way south to overwinter in the southern U.S., where the species is a year-round resident.
Along the way, the lichen grasshoppers continued to attract our attention due to their abundance and striking diversity of coloration. We were treated to a particularly obvious example of this when we encountered a mating pair with the much smaller male exhibiting shades of brown instead of the greens exhibited by the much larger female.
It had been a leisurely descent off the main glade, and once clearing the woodland to emerge into the last glade fragments before the final descent, Chris and Ted were further delayed by a trio of observations in rapid succession. A large, impressively marked Neoscona crucifera (spotted orbweaver) spider hunkered down on a twig first caught Chris’ attention. Photographing it turned into an adventure when an effort to manipulate the twig on which it was resting ended up alarming the spider and causing it to drop down to the ground. They returned the spider to the twig using other twigs and leaves, but invariably it dropped again. Eventually, they learned they could “reel” the spider back up to the twig by its silk line if they acted quickly enough, and with repeated efforts both succeeded in getting photographs of the spider back up on the twig.
While this was going on, the unmistakable droning buzz of Milesia virginiensis (yellowjacket hover fly or Virginia flower fly) caught their attention. The resemblance of the adults of this species to wasps is remarkable, and they are often seen hovering in midair, making erratic shifting movements, and then suddenly flying away. This particular fly, however, cooperated by landing on a rock (briefly) and allowing a few photographs before it abruptly departed.
Spider and fly photographs in hand, Ted and Chris resumed their descent but took only a few steps before another sighting demanded photographs—a rough green tree snake (Opheodrys aestivus) peering quizzically from amongst the rust-red leaves of a stunted blackjack oak. The snake cooperated at first, allowing a few closeup photographs before making a run for it. Fortunately, this is a very docile species that rarely (if ever) bites when handled, so Chris and Ted were able to corral it for additional photos before returning it back to the tree from whence it came.
Opheodrys aestivus (rough green snake—family Colubridae).
At last, they were able to complete the descent and join the rest of the group in the parking lot, but not before making one last interesting find—the bizarrely beautiful caterpillar of Isa textula (crown slug moth). Like many members of the family Limacodidae (slug moths), the pale green, flattened caterpillars bear stinging spines/-in this case on lobes that radiate out from around the edge of the body. The caterpillar was found on the ground (it is probably mature and was looking for a protected place to spin a cocoon in which to spend the winter) and coaxed onto a leaf to bring it to the parking lot so everyone could have a chance to photograph it (it looked particularly stunning when set on a bright red sumac leaf).
6 Oct 2025—Fall continues to advance in the St. Louis area, and despite very dry conditions during the past two months the fall bloomers continue to make their appearance. One of the area’s most reliable and interesting places to see fall blooms is Victoria Glades south of Hillsboro, where orchids, gentians, and asters anchor a unique suite of fall-blooming plants that are rarely seen elsewhere in our mostly forested environs.
The group chose the Nature Conservancy portion of the complex to explore, as it was in the mesic forest along the riparian corridor below the glade on this side that the first of two orchids—the charmingly diminutive and seldom-seen Spiranthes ovalis (lesser ladies’ tresses)—was expected to be seen in bloom. Despite having recently taken GPS coordinates for the plants, it took several minutes of the group scouring the area around the coordinates before the tiny plants were finally found. Its delicate blooms, fall flowering season, small size, presence of basal and cauline leaves at anthesis, and preference for mesic habitats all serve to identify this species. Missouri’s populations are considered var. erostella, which lack certain essential flowering organs and are, thus, self-pollinated (cleistogamous).
Spiranthes ovalis var. erostellata (lesser ladies’ tresses—family Orchidaceae).
Clambering up and out of the creek bed and onto the open glade, the group found, again with some difficulty, the second orchid we were looking for—Spiranthes magnicamporum (Great Plains ladies’ tresses). Unlike S. ovalis, however, this species is much more commonly seen on dolomitic glades throughout the state, and there have been fall seasons at Victoria Glades featuring spectacular displays of it. Sadly, it does not appear that this will be one of those falls, almost surely because of the near absence of rain in recent months. The first two plants were found under and next to a cut eastern red-cedar, whose cadaver perhaps provided just enough protection to prevent a complete drying of the soil underneath and allowed the two plants to proceed to flowering. Of the nine species of Spiranthes presently known to occur in Missouri, S. magnicamporum is among the showiest due to its robust, often doubly helical inflorescences and relatively large flowers with spreading and arching lateral sepals. It is also among the most fragrant, with a sweetish fragrance of coumarin, which some people liken to vanilla.
I’ve been visiting Victoria Glades for more than 40 years, yet I continue to see things I haven’t previously notified. This time it was Trichostema coeruleum (pennyroyal bluecurls), a member of the mint family (Lamiaceae). [Note: Trichostema coeruleum was known until recently as Trichostema brachiatum—now a synonym of Trichostema dichotomum.] Unlike Trichostema dichotomum (bluecurls), which prefers glades and other dry habitats with acidic substrates (e.g., sandstone), T. coeruleum prefers such habitats with calcareous substrates (e.g., dolomite). A third species of the genus, Trichostema setaceum (narrow-leaf bluecurls), also occurs in Missouri but is restricted to sand prairies in extreme southeastern Missouri.
Dolomite glades are also the preferred habitat for many species of plants in the family Orobanchaceae, a bizarre family of mostly hemiparasitic plants that derive at least some of their nutrition not from the sun, but by tapping into the roots of nearby plants. Castilleja coccinea (scarlet paintbrush) is perhaps the best known of these, in most years joining the cacophony of wildflowers that form colorful displays across Victoria Glades during spring and early summer. There are, however, several less conspicuous but equally beautiful wildflowers in the family that are restricted in the area almost exclusively to the dolomite glades of Jefferson Co. One of these is Agalinis skinneriana (Skinner’s or pale gerardia/false foxglove), which the group found sporadically still in bloom across the open glade. There are several species of Agalinis in Missouri, some of which are quite common. However, A. skinneriana can usually be recognized by the characteristic habitat and generally upward-facing flowers with spreading to reflexed upper corolla lobes. The plants are also relatively slender and fewer-branched than the more common A. tenuifolia (common gerardia/false foxglove) and A. gattingeri (rough-stemmed gerardia/false foxglove).
Agalinis skinneriana (Skinner’s or pale gerardia/false foxglove—family Orobanchaceae).
Another plant in the family Orobanchaceae that the group saw was Buchnera americana (American bluehearts), represented by a single plant still bearing two worn blossoms. Normally blooming from June through September, plants in full bloom have no look-alikes and are not likely to be confused with anything else. Despite this, the vervain-like fruit-bearing structure of this late straggler fooled the group into at first thinking it was a species of Verbena until its true identity was realized.
Buchnera americana (American bluehearts—family Orobanchaceae).
No group of plants more iconically represents fall than goldenrods (genus Solidago) and true asters (genus Symphyotrichum), and no place allows as many uncommonly seen species to be seen together as the dolomite glades. Three species of goldenrods were seen during the day—the super common Solidago nemoralis (old field goldenrod), the less common but more showy Solidago rigida (stiff goldenrod), and the highly restricted Solidago gattingeri (Gattinger’s goldenrod) (we were not able to locate a fourth species—Solidago radula [rough goldenrod], which we have observed during previous visits on the MDC portion of Victoria Glades). It was the true asters, however, that truly tested our plant identification abilities. Relatively easier are the purple asters, of which we found three species. The first and most abundant was Symphyotrichum oblongifolium (aromatic aster), recognized by its recurved phyllaries and branched habit with narrow, linear leaves that become more numerous and smaller in the upper plant. If one is still in doubt as to its identity, however, one needs only to crush the leaves between the fingers and enjoy its distinct aroma.
Along the intermittent creek and near the interface with the dry post oak woodland on the north of the glade, we encountered a second species—Symphyotrichum oolentangiense (azure aster). Identification of this species came only near the end of the outing, as a key identifying characteristic of this species—the presence of distinctly petiolate cordate basal leaves that are rough to the touch—was not seen on any of the plants examined before then. At that point, we suspected Symphyotrichum turbinellum (prairie aster) due to the vase-shaped involucres. While that species has been found at Victoria Glades, it is usually a much more highly branched plant associated with more wooded habitats (despite the common name). Finally, we found a plant with such leaves present, albeit dried up, and then another with the leaves present and still fresh to confirm the identification.
Symphyotrichum oolentangiense (sky blue aster—family Asteraceae).
In a small area at the northernmost point of the glade, we found Symphyotrichum sericeum (silky aster). This species is immediately recognizable from afar by the silvery cast to the foliage—this, combined with its highly preferred habitat of glades or dry prairies are usually enough to identify the species, although it is said that the flowers are often more purple and less bluish than other “purple asters.”
As we walked the margins of the glade, the group kept their collective eyes out for Gentiana puberulenta (downy gentian), a striking and rarely seen fall flowering species that has been found on several occasions at Victoria Glades. The species has been seen at Victoria Glades on a few occasions in past years, and the locations of these sightings were scoured thoroughly but without success. Unexpectedly, near the end of the outing, a single plant in flower was located—its perfectly fresh blossom initially hidden from view underneath fallen leaves. One of three members of the genus Gentiana in Missouri, this species is easily differentiated by having the corolla spread open at maturity. Missouriplants.com notes “The rich, deep blue color of the corollas is a striking and uncommon hue among our flora.” A strikingly beautiful final find of the day indeed, and a perfect note on which to gather for lunch at historic Russell House in nearby Hillsboro.
For me, no botany outing is strictly about plants (just as no entomology outing is strictly about insects), so there were a few interesting insect observations on the day. On our way to look for Spiranthes ovalis (lesser ladies’ tresses), June noticed a caterpillar on the Ulmus rubra (slippery elm) that we decided must represent Halysidotus tessellaris banded tussock moth).
Later, after lunch with the group, I returned with the goal of more closely inspecting Physocarpus intermedius (Midwest ninebark) along the glade toeslopes and intermittent creek to see if Dicerca pugionata was out. It has been many years since I’ve seen this species in the fall (but it has also been many years since I’ve really tried to look for it during the fall). I started first with the plants along the moist toeslopes along the west side of the glade, checking several of the now very scraggly-looking plants without success. Along the way, I encountered an especially beautiful Spiranthes magnicamporum, so I paused to take photos. While doing so, I noticed a cryptically-colored crab spider on its blossoms—Mecaphesa asperata (northern crab spider)—the first time I’ve ever seen a spider hunting on the flowers of an orchid.

Towards the end of the toeslopes, finally, two D. pugionata plopped onto my sheet. The plant they were on was near the far end of the toeslopes, and if I hadn’t seen any beetles by the time I reached the far end I would have given up the search. Finding them, however, motivated me to hike over to and continue looking along the intermittent creek, where I saw three more beetles in three different spots, the last one—satisfyingly—on the very last plant I checked before the creek disappears into denser woodland.

Mission accomplished, I enjoyed one more leisurely stroll across the glade before calling it another (successful) day in the field.
After missing the last three weeks, I was happy to rejoin the WGNSS botanists on their regular weekly outing this past Monday. This week’s destination—Salt Lick Point Land & Water Reserve in western Monroe Co., Illinois—features a mosaic of loess hill prairie and limestone glades amidst dry to dry-mesic upland forest atop limestone bluffs towering up to 400 feet above the Mississippi River valley below.

It has been an exceptionally dry August and September, so much that fall blooming plants are noticeably delayed and sparse in their blooms. Nevertheless, welcome rains just in the past few days have breathed some “fall life” into the woods and brought with them the pungent, earthy aromas that one expects to accompany a landscaping morphing from the dull greens of summer to the vibrant ambers, tawnies, and golds of fall.

The group first explored the upland and blufftop habitats along the challenging terrain of the Salt Lick and Newman Trails, then returned through flat lowlands along the bluff bottoms via the Johnson Trail. Although still just beginning to bloom, a diverse palette of “fall asters” gave us an opportunity to reacquaint ourselves with the characters that distinguish these often “easy-to-identify-to-genus but difficult-to-identify-to-species” plants. The bulk of these fell into one of two groups—the true asters (genus Symphyotrichum) and the goldenrods (genus Solidago).

Symphyotrichum patens (late purple aster) was the first true aster that we noticed, a rather common species distinguished by its purple (of course) flowers with loose but not recurved phyllaries and leaves broadly clasping the stem. It wasn’t long before we had a chance to test our knowledge when we encountered the similar appearing Symphyotrichum anomalum (manyray aster), also with purple flowers but distinguished from S. patens by its distinctly recurved phyllaries and petiolate rather than clasping leaves. Eventually, we would encounter a third species of the genus—Symphyotrichum lateriflorum (calico aster), distinguished by its numerous small white flowers at the tips of numerous lateral branches rather than the terminus of the stem.
View from the Newman Trail at Salt Lick Point.
Goldenrods, on the other hand, were not only more diverse but also comprised some quite conservative species. The first of these was Solidago drummondii (Drummond’s goldenrod). This near-endemic species is restricted to eastern Missouri and adjacent parts of Illinois and Arkansas and grows almost exclusively on limestone or dolomite bluffs. However, we found it growing on limestone boulders placed at the trailhead next to the parking lot. Its wide, toothed leaves on short petioles (along with habitat) make this species easy to identify. Another quite conservative goldenrod was found as we entered the dry to dry-mesic forest further up the trail—Solidago buckleyi (Buckley’s goldenrod). Restricted to the Ozarks and adjacent areas, it is a showy species with relatively large flowers and spready phyllaries. In this and other respects, it greatly resembles the much more common Soldago petiolaris (downy goldenrod); however, it differs from that species by its narrower leaves that lack distinct teeth. A third species was seen as we approached one of the larger loess hilltop prairie remnants—Solidago altissima (tall goldenrod). Unlike the previous two species, this is one of the commonest and weediest species of goldenrod in the region. Relatively tall and with pyramidal inflorescences, this species often aggressively monopolizes roadsides and fallow fields. It greatly resembles another fairly common species—Solidago gigantea (late goldenrod), which we would later see during the return hike along the edge of the river valley. Leaf texture, however, differs between these two species—S. altissima has leaves with rough surfaces (caused by stiff, unidirectionally recurved hairs that cause the leaf to move only one direction when rubbed between the thumb and forefinger), while S. gigantea has smooth leaves (that move in any direction when rubbed).
The group not only spent its time with its eyes down, but also out—across the vast Mississippi River valley spread out below the several lookout points dotting the trails. Tawny fields of near-ready-to-harvest corn provided a beautiful backdrop against the resplendent red sumacs and brilliant orange maples lining the blufftops.

As the group’s lone entomologist/botanist (“entomotanist”?), I also kept an eye out for insects and was richly rewarded. A tiny “thorn” on the stem of S. buckleyi proved to be Enchenopa latipes (wide-footed treehopper), and unfolding the “folded” leaves of Cercis canadensis (eastern redbud) revealed the culprits—zebra-striped caterpillars of Fascista cercerisella (redbud leaffolder moth).

A spectacular earth boring beetle, Geotrupes splendidus, was seen lumbering clumsily along the trail in its endless quest for mammal dung to bury and lay an egg upon, while Bombus impatiens (common eastern bumble bee) worked the flowers of Eupatorium altissimum (tall boneset) and Eupatorium serotinum (late boneset).

Nowhere, however, was insect activity more abundant than on the goldenrods, particularly the abundant stands of S. altissima in the uplands and S. gigantea below. Overwhelming numbers of Chauliognathus pennsylvanicus (goldenrod soldier beetles) and Lycomorpha pholus (black and yellow lichen moths) were accompanied by a cacophony of bees, wasps, and flies—a situation tailor made for Phymata sp. (jagged ambush bugs) to lay in wait while Epargyreus clarus (silver-spotted skipper) flew erratically overhead.

Even in the deeply shaded mesic forest, Cyllopsis gemma (eastern gemmed satyrs) flitted deftly through the undergrowth.

The most unusual find, however, was a bizarre, green, jewel of a caterpillar found crawling on the forest floor—Isa textula (crowned slug moth or skiff moth), fringed with lacy projections that make it look more like a sea slug than an insect!

Of course, a Monday WGNSS Botany Group outing isn’t truly consummated until it has enjoyed lunch at a local establishment—the choice this time being Tequila Mexican Restaurant in nearby Waterloo (best fish tacos I’ve ever had!).
This—the 18th “Collecting Trip iReport”—covers the second of two insect collecting trips to the southwestern U.S. this season—this first one occurring from June 4–13, during which I placed “bottle traps” and “jug traps” at several locations, and this one from September 3–14 to retrieve the traps and take advantage of any late-season collecting opportunities. I was fortunate on this trip to have longtime collecting buddy and melittologist Mike Arduser joining me, during which we visited the same 15 localities that I visited on my precious trip back in June (one in northwestern Oklahoma, six in northern Arizona, six in southern Utah, and two in southern Nevada) plus two additional localities (one each in northwestern Oklahoma and northeastern New Mexico).
I’m on my way out west with fellow collector Mike—today being only a travel day but with a quick stop in Texas Co., Oklahoma to retrieve bottle traps set back in June and then a night of camping at Black Mesa State Park before continuing the drive west tomorrow. After 7 hours, we needed to stretch our legs and stopped at Salt Plain National Wildlife Refuge’s Sandpiper Trail—a spot we both have visited several times and know well. Recent rains had the alkaline flats filled with more water than I’ve seen during any previous visit, …
Salt Plain National Wildlife Refuge, Alfalfa Co., Oklahoma.
… and only a few Ellipsoptera nevadica knausi (Knaus’ tiger beetle) and Eunota circumpicta johnsoni (Johnson’s tiger beetle) were seen on the drier margins of the alkaline flats. Several Epicauta conferta (red-cornered blister beetle) were seen lumbering across the path, and a Diogmites angustipennis (prairie robber fly) posed nicely on the trail for pictures as well.
Showy Eustoma russellianum (prairie gentian)—a plant I’ve never seen before—were blooming spectacularly and prolifically in the vegetated areas bordering the alkaline flats.
It was a quick but interesting stop that rejuvenated the legs before we continued our journey westward.
The first “real” stop of the trip was ~5 miles north of Goodwell in Texas Co., Oklahoma where I placed three white bottle traps in early June hoping to capture the very rare Acmaeodera robigo, which had been photographed here on flowers of Melampodium leucanthemum (blackfoot daisy) and the photos posted on BugGuide. I was never able to contact the photographer, but since bottle traps are so effective at sampling species of Acmaeodera I reasoned placing three traps here (one at the precise spot and two more several hundred yards to the north and to the south) would give me the best chance of collecting it. It had already been dark for an hour before we reached the spot, but despite the darkness and late hour I had no trouble finding each of three traps. I was happy to see all three traps still in place, undisturbed, and filled to the brim with insects. I tried to pick out the larger insects (mostly crickets and grasshoppers) and stir through the remaining contents of each trap a bit to see if I could detect any Acmaeodera, but the majority of insects appeared to be small blister beetles, followed by bees. The darkness made further sorting impossible, so I bagged the contents of each trap and saved for later sorting. [Edit: later sorting found only a couple of Acmaeodera mixta? in just one of the traps and no A. robigo.]
We arrived at our first overnight spot—Black Mesa State Park—quite late (~11:30 pm) and quickly setup camp before retiring for the evening. In the middle of the night I got up, came out of the tent, and was greeted by an incredible amazing starscape that is normally only seen during winter. Taurus was already high in the sky, and Orion was well above the horizon with a brightly shining Jupiter not too far to its left.

Day 2
In the morning, a canyon towhee (Melozone fusca) kept us company as we prepared breakfast and then broke camp for another mostly travel day

Our destination this evening is Devils Canyon Campground near Monticello, Utah, to which we will travel by way of northeastern New Mexico and then southwestern Colorado.
Abandoned homestead outside of Clayton, New Mexico.
Shortly after crossing into Colorado we made a pit stop for ice and I began searching the pavement around the gas station looking for beetles that may have come into the previous night’s lights. I didn’t find any cerambycids but I did find a small tenebrionid beetle that didn’t look like familiar to me.
Crossing the Sangre de Cristo and then the San Juan ranges were as spectacular a mountain crossings as any that Colorado has to offer, and a coffee stop in Pagosa Springs (at Faire Society Cafe and Patisserie) provided not only good coffee and pastries to fuel me for the rest of the drive to Devils Canyon Campground near Monticello, Utah, but interesting and creatively framed art work to treat the eyes while waiting for our orders.

Weather during the drive had been good all day, but on the final approach to Devils Canyon Campground the skies began looking worryingly threatening. The last time I came here (early June) I had intended to camp here but got rained out and took a motel in town. I did not want a repeat of that, so we kept our fingers crossed and made the final drive to the campground. Although still threatening, it was not actually raining when we arrived (unlike last time), so we took our chances and set up camp. No sooner than that did the rain start! Fortunately, the tent was already up, so it just meant that instead of cooking dinner at the site, we would instead go to town and have dinner (Dave’s BBQ). When we got back to camp, the rain had stopped (although we could tell that it had rained hard), so I decided to walk the roads looking for night-active beetles. I knew this was probably a fruitless exercise—by then the post-rain temps at this 7000’ site were already down to the mid-50s, but it would give me a chance to stretch my legs after two straight days of driving, and I could also take that opportunity to retrieve the bottle and jug traps that I had set back in June. The bottle trap was disappointing, especially after seeing the ones I’d set near Goodwell, Oklahoma filled to the brim with insects—just a handful of bees (for Mike) and no beetles of any kind. This was surprising given the many Acmaeodera I have collected in alpine habitats just like this (Ponderosa pine and Gambel oak). The SRW-baited jug trap, on the other hand, was nicely (if not overwhelmingly) productive (Tragosoma sp., Enaphalodes sp., small elaphidiines, small acanthocine with very long antennae, Xestoleptura?)—enough to make it worth the effort. I was also pleased to see that the jug trap was in still place and intact with the catch in good shape despite three months in the field. The bait bottle was still about half full of red wine, but since the propylene glycol had dried the trap was no longer trapping insects. As I’d expected, no night-active insects were seen in the way to the traps or on the way back.
Day 3
It was a chilly morning, and though it had not rained since our arrival last night the skies remained overcast. The day’s plan was to continue west to the Ponderosa Grove Campground in southwestern Utah (north of Kanab), but with only five hours of driving required to get there we would have time to make a few stops along the way. Before leaving I started checking the Ericameria nauseosa (rubber rabbitbrush), several of which had begun blooming in the campground, and found a few Crossidius coralinus and Acmaeodera amabilis on the flowers. I was tempted to suggest staying put—at least for a short time—and exploring the area a little more fully, but my real objectives were further west and I elected to stick with the plan.

One of the stops I’d made along this way last June was 4 miles east of Bluff in San Juan Co., Utah, where the famous Mont Cazier had collected what would later be described as Agrilus utahensis. I did not find it in June (nor did I fully expect to, since the record was from late July), and I was equally skeptical about my chances this time given how much later it was in the season. On the way here, we got caught behind an oversized load on the highway that was so big it required three highway patrol chaperone vehicles to clear the road ahead. Going at about half the speed limit, I worried we might have to follow it the entire way to our turnoff, which would nearly double our travel time to the first spot. Fortunately, the caravan pulled over at one point to let the long train of trsffic that had accumulated behind it pass, and we were on our way (the convoy would later pass us at the very spot where we had stopped to collect).
Oversized convoy!
The location was disappointing dry and crispy, although Gutierrezia sarothroides (broom snakeweed) was coming into bloom. Sweeping it eventually produced about a dozen Crossidius pulchellus and two other beetles (a clytrine leaf beetle and a weevil), and Mike collected a handsome series and diversity of bees off of flowering Eriogonum sp. (buckwheat).

Our drive afterwards through southeastern Utah and northeastern Arizona took us through some of the most amazing scenery that the American West has to offer—red sand/siltstones sculpted through the eons by wind and rain have created a landscape that can only be described as “planetary.”

Eventually, the dramatic landscape gave way to a more monotonous series of desert plateaus periodically interrupted by dramatic descents and canyons as we got deeper into north-central Arizona. Though pleasing to the eye, there were few signs of greenery of flowers to tempt the passing entomologist except occasional stands of Ericameria nauseosa (rubber rabbitbrush) beginning to bloom in higher elevation spots. We kept our nose to the grindstone, hoping to see better things once we passed through Page and crossed back into south-central Utah, but the landscape became even crispier, with a stop about 20 miles northwest of Page to look for Nanularia brunnea on Eriogonum inflatum (which I had found two years ago in late June) being a total bust. We expected/hoped that the higher elevations around Ponderosa Grove Campground (~6000’) would provide better collecting and continued there without haste. Our expectations/hopes proved well-founded, as blooming rabbitbrush was seen with greater frequency as we traveled north of Kanab and even more so along Hancock Rd approaching the campground. We took a few moments to scout out a good campsite and setup camp before spending the rest of the available daylight hours exploring. For me the rabbitbrush was most tempting, and scouting plants in the campground and the vicinity east produced small but nice series of Crossidius coralinus and Typocerus balteatus. As I was doing so, a sinking sun and virga to the east produced an impressive rainbow that became irresistible for photography—not only as a subject itself but as a backdrop for the beetles I was finding.

After some downtime back at camp (and grilled sirloin steaks for dinner), I did my customary nighttime patrol to check for night-active insects. This campground was especially productive when I did this back in June and found several Zopherus utahensis and other tenebrionids on the trunks of the massive Ponderosa pines that are the namesake of this campground.

This time was no different—while I found only a single Z. utahensis, I did also find a few specimens of Coelocnemis sulcata, including a mating pair, on the trunks of the trees …

… and a single Embaphion sp. on the ground at the base of another. There are several massively-trunked Juniperus osteosperma (Utah juniper) in the campground as well, on which another C. sulcata was found. Despite this success and the relatively early hour, I was exhausted and called it quits for the night and retire. We will spend the entirety of the day here tomorrow, so I’ll have another chance to check the tree trunks again tomorrow night.
Day 4
After a relaxing morning at the campsite (during which time I caught up on my field notes while enjoying double-pour-through coffee), I walked over to the sand dune-adjacent woodlands to retrieve the traps that I’d set there back in June and brought them back to the campsite for sorting. I was happy to see Ericameria nauseosa (rubber rabbitbrush) and many other plants in bloom and looked forward to checking them more closely after servicing the trap catches.

The yellow bottle trap had ~15-20 beetles, including several Acmaeodera spp., a lepturine cerambycid, and a tiny Dichelonyx-like scarab (a relief after getting skunked with the bottle trap I’d set in Devils Canyon). There were also a fair number of bees in the trap, which I gave to Mike. The SRW-baited jug trap also did well, containing Tragosoma sp., Enaphalodes sp., several Psyrassa sp., and another colorful little lepturine along with several Euphoria inda, several small clerids, a mantispid, and numerous small beetles I take to be oedemerids. After processing the trap catch, I went back over to the woodlands and dunes, spending more than three hours collecting off the flowers of E. nauseosa and other flowers.
Typocerus balteatus was found not uncommonly on the flowers in most of the areas that I covered, while Crossidius coralinus and C. suturalis were found a bit more sparingly.

I also found Acmaeodera rubronotata on the flowers of Grindelia squarrosa (curlycup gumweed), Dieteria canescens (hoary tansyaster), and E. nauseosa, but they were limited to the woodlands and not seen in the dunes.

I also found several individuals of an interesting little weevil on the rabbitbrush flowers, its gray/black longitudinally striped body making a good subject for photography (for which I also brought back a live A. rubronotata and a mating pair of ambush bugs), and spent a bit of time photographing some of the other blooming plants in the area.
By the time I feel like I’d gotten a good enough look at the area, nearly four hours had gone by and I was famished. Sardines and Triscuits did the trick, after which we did a quick ice run into town and back—the highlights being an authentic Sinclair dinosaur (he’s smiling!) and an real (though non-functioning) pay phone.

Returning to the campground, I walked with Mike back into the dunes to retrieve his bowl traps. I had hoped that some of them would pick up Acmaeodera (as is often the case with bowl traps and why I have started utilizing them on my own collecting trips), but the only species that would be out in this area at this time of season would be A. rubronotata, which I had already collected earlier in the day (there were none).

After a period relaxing (with a cold beer and burgers hot off the grill), I began my customary night walk. I have yet to find a cerambycid on tree trunks at night here, but still I enjoy night walks here as much as anywhere due to the consistent presence of ironclad beetles and other tenebrionoids on the trunks of the massive Ponderosa pine trees that give the campground its name.
Another near-full moon rises over the campsite.
Tonight would be no different—I found Zopherus uteanus on just the second tree that I examined (right in our campsite), and I would also find two species of tenebrionids in the vicinity on the trunks of ponderosas (Coelocnemis sulcata and Eleodes obscura sulcipennis) and a third species (ID unknown) on the ground at the base of one of them.

At that point, I decided to go outside of the loop towards a couple of large P. ponderosa at the entrance, and on the way I found another E. obscura sulcipennis on the trunk of a massively old Juniperus osteosperma (Utah juniper). There was nothing on the P. ponderosa trees that I had targeted, but nearby was another large one, and high up on the trunk (as far as my fully extended net could reach) was another Z. uteanus, and several C. sulcata—including a mating pair—were found on the ground at its base.
At that point I decided to limit my tenebrionoid collecting to only Zopherus unless I saw species that I hadn’t seen before, so I passed by some additional tenebrionids of the same species as the previous on a large P. ponderosa in the RV loop, then saw a large, multi-branched Pinus edulis (Colorado pinyon pine) that I thought might be interesting to check. I did not find any beetles on it, but I did locate at eye level—with considerable difficulty!—a male Oecanthus californicus (western tree cricket). I was not only able to take a photograph of it with its wings fanned but also record an audio track up close (posted on iNaturalist).

Returning to the tent loop, I checked all of the large P. ponderosa trees and junipers that had—during the past visit and last night—been so productive, but the only beetles I found was a very small tenebrionid that, fortunately, was yet another species I had not previously seen here (ID unknown). After two hours of searching tree trunks, I called an end to the night, which also meant a close to the collecting at this spot—tomorrow we will drive to Kyle Canyon in southern Nevada!
Day 5
Our exit from Ponderosa Grove took us through more of the spectacular canyonland that southern Utah is famous for and past the incredible Coral Pink Sand Dunes State Park (so spectacular it is that I think it could—despite its small size—be a national park). A dramatic descent down into the Virgin River valley and the town of Hurricane was only the first such descent—the second one being even more dramatic as I-15 dropped off the edge of the Colorado Plateau along the Virgin River Gorge. The remainder of the drive to Kyle Canyon northwest of Las Vegas was mindnumbing in its contrast—an endless stretch of interstate highway through a vast expanse of low, hot, featureless desert punctuated at regular intervals by palm tree dotted oases, each with a gaudy, glittering casino at its center. Driving up Kyle Canyon Rd put an end to this, however, as each thousand foot gain in elevation brought with it an increasingly interesting landscape. At about 4500’ elevation, I had set a couple of bottle traps—one yellow, one blue—hoping to catch the recently described Acmaeodera raschkoi (whose namesake—Mike Raschko—I had happened to meet at Ponderosa Grove Campground last June a few days before I set the traps!). Mike R. had also placed a bottle trap (white) at the site and was kind enough to reset it for me so I would have three colors sampling the area. Both of my traps were still in place, intact, and filled with numerous Acmaeodera that I take to be A. quadrivittata (along with many bees for Mike A.) and the yellow also containing a larger species that I didn’t immediately recognize (not unusual since I have never collected this area). Unfortunately, I did not see any specimens that appeared to be A. raschkoi, and even more unfortunately the white bottle trap had been pulled from the ground (although I was able to recover a few A. quadrivittata that were still inside the trap). Not much else was going on at the site—only a few things in sparse bloom but no beetles visiting the flowers, nor was there any rabbitbrush around on which to look for Crossidius.
We got a scare when we arrived at the campground and saw a sign at the entrance saying “Campground Full.” This was bad—if this campground was full, then surely the much more heavily used one down below was also full, and I didn’t look forward to spending the rest of the afternoon scrambling for a campsite somewhere in the Spring Mountains. We drove through the campground anyway, and, in fact, there were many campsites available! Looks like somebody forgot to do their job!

Crisis averted, we selected a nice spot overlooking the desert below and set up camp. Cool evening temps come early at this high elevation (~8300’), so with the remaining afternoon hours I retrieved and sorted my SRW-baited jug trap, finding several Tragosoma sp. but, curiously, not a single other longhorned beetle (or any beetle for that matter). Searching around the area afterwards, I extracted a dead Dicerca tenebrosa partial carcass in its emergence hole in a stump of Pinus monophylla (single-leaf pinyon pine), then went back down to the area I had collected last time, focusing especially on the two large half-dead Juniperus osteosperma (Utah juniper) trees on which I had seen damage from the rarely collected Semanotus juniperi (on one of which I collected three adults later that night). There was nothing on the first (the one on which I found the beetles), but at the second one I saw a large wind-thrown branch that I had not noticed last time. It exhibited S. juniperi damage and emergence holes on the lower part, and chopping into it I quickly recovered a dead but intact carcass of yet another S. juniperi adult. Further chopping turned up nothing, and I was about to walk away when I thought maybe I should cut into the upper part of the branch as well to look for evidence smaller woodboring species. Doing so, I quickly encountered a Chrysobothris sp. larva, and with that I decided to bring the entire upper part of the branch back for rearing. There wasn’t much else going on—few plants were in flower and nothing was seen on the trunks of trees or various pieces of downed wood that were laying about, so I went back to camp.

Later in the evening, we watched a spectacular moonrise, then enjoyed “surf ‘n’ turf” (grilled sirloin steak and salmon) before I started up my customary night walk to check tree trunks for night-active beetles.

Last time here when I did this, I found not only S. juniperi but also a few Zopherus uteanus, so I was hopeful for my chance tonight despite the lateness of the season. It started out well—on the first P. monophylla tree that I checked (right at our campsite), I found Oeme costata and a weevil.

Those would be the last live beetles I would see (other than an occasional tenebrionid beetle, none of which I collected). However, I would still find success—back at the J. osteosperma on which I had found three S. juniperi back in June, I found three more. They were not alive, however, but dead carcasses at the base of the tree—two nearly completely intact and the other partially so.

Day 6
We had planned to visit few localities at middle and lower elevations but stopped to check out the profusely-blooming Ericameria nauseosa (rubber rabbitbrush) right outside the campground entrance for bees and beetles. Curiously, hardly anything was seen on the flowers despite the by then late-morning hour, sunny skies, and temps above 70°F. It seemed odd to me that there were no Crossidius beetles on the blooms, and the thought occurred to me that maybe the occurrence of E. nauseosa in the area itself could be a relatively recent phenomenon since it is only seen—albeit profusely—along the roads and highways in the area but nowhere further within the native habitats. With nothing going on, we pushed down to the lowest elevation point that caught our eye on the way in yesterday—the Step Ladder Trailhead at ~6700’.
Again, E. nauseosa was blooming profusely around the parking lot, but a quick perusal made it clear the situation would be similar here as well. Mike, on the other hand, was having good success collecting bees off of E. nauseosa and especially Gutierrezia sarothrae (broom snakeweed), so I was content to stay and refocus by searching for infested wood. I noticed a lot of Quercus gambelii (Gambel oak) and quickly found one with a dead but still attached, fully-barked branch. I broke the branch off the tree, and there in the broken butt of the branch was a large chrysobothroid larvae! This quickly prompted a decision to collect the infested branch and put it up for rearing. A second larvae was found in a small dead (but still fully-barked) tree nearby, which was added to the bundle. While this was going on, Mike found what seemed to be Agrilus blandus? in his net while sweeping bees from the flowers of G. sarothrae. I recall collecting this species in southern California in flowers of Eriogonum (wild buckwheat), so finding it on other flowers—particularly if Eriogonum is in the area (but not seen because it was not blooming) did not seem out of the question. My much more thorough sweeping of the plants around the area where he found it, however, produced no additional specimens. I was also interrupted in my sweeping attempts by a couple of curious bystanders—one a woman from Ukraine who wondered what the plant was that I was sweeping (I told her “broom snakeweed”) and what it was good for (“brooms” I wryly replied and then quickly clarified its role in the ecosystem), and then offered me a beetle collecting tip by telling me about large beetles they call “bombers” and that bite people sitting in spas in Southern California (I presume these are diving beetles in the family Dytiscidae); and the other a young man who was pleased to hear I was from St. Louis because he used to live there when he was married to his ex-wife. This all happened while I was in the middle of my sweeps, so I held the net bag firmly to keep insects from escaping my net until I could resume my sweeping. Eventually, I gave up the ghost and resumed my search for dead, infested wood, eventually finding a Cercocarpus ledifolius (curl-leaf mountain mahogany) tree with one recently-dead and one older dead branch, the former buprestid-infested (verified by cutting into the wood and finding young buprestid larvae) and which I collected for rearing.

… I wanted to check out the nearby Deer Creek Picnic Area where I’d seen a lot of iNaturalist observations (suggesting it might be an interesting place). At first all I saw was the massive parking lot below an equally massive road-cut slope—the only thing that looked like a trail was a steep drop down to the creek below. I checked it out, only to find it dead-ending at the creek and clambered back up.
A massive Ponderosa pine looms above.
Then I saw a gravel trail behind the guardrail on the opposite side of the highway and found it leading to a paved path up the creek. Much of the trail was covered with a deep layer of gravel from flooding (and indeed some of the picnic tables were also nearly completely buried). I hiked the trail as it ascended alongside the creek under massive ponderosa pines until it dead-ended at a gravel road and turned around. The only plants in flower was Ericameria nauseosa (rubber rabbitbrush), and it was only near the highway, and while I saw no insects that I wished to collect, I did see a large Adejeania vexatrix (orange bristle fly) that frustrated my attempts to photograph it until I finally “pre-set” the focus, exposure, and zoom and quickly fired off a few shots at the distance I’d set it for as soon as the fly landed. The virtual lack of insect activity here confirmed what we’ve been seeing in the area as a whole, so I’ll be anxious to leave tomorrow and head for (hopefully) greener pastures at Leeds Canyon back in southwest Utah.

Day 7
The drive from Kyle Canyon to Leeds Canyon was essentially a straight shot on I-15—normally a recipe for extreme boredom; however, coming back up through the Virgin River Gorge was a different, even more awe inspiring experience than the descent two days earlier. Ascending such a steep narrow canyon has the breathtakingly tall canyon bluffs looming high overhead, dwarfing the traffic, even the largest semi tractor trailers, snaking up below, whereas descending into a seemingly bottomless chasm feels a little more “dangerous.” We arrived at Leeds Canyon relatively early thanks to the “only” 3-hours drive. The area looked very dry, but a variety of blooming plants kept us optimistic as we made our way up the canyon road towards Oak Grove Campground at the top.

Sadly, optimism turned to dismay in an instant when we encountered a “Road Closed” sign about halfway up—a result of the ongoing fire risk that has bplagued the area this season. We checked to see if the campground on the other side of the mountain range was available, only to learn that it was closed due to fire damage. At that point, our decision was made for us—we would need to continue another two hours to the Kaibab Plateau where I had my last sets of traps to retrieve and where we could camp at Jacob Lake. While we were here, however, we took the opportunity to stop at a spot along Leeds Creek and see what we could find.

Several different plants were in bloom, on which I’d hoped to find either Acmaeodera or longhorned beetles, the first that I looked at being Dieteria canescens (hoary tansyaster), but I only saw small dasytines (a few of which I collected). Nothing was seen on Solidago velutinus (velvety goldenrod) or Sphaeralcea grossulariifolia (gooseberry leaf globemallow) flowers, but then Mike came up with a Crossidius discoideus on flowers of Gutierrezia sarothrae (broom snakeweed).

Careful searching of the plants in the surrounding area atop a small hill turned up an additional half-dozen individuals, but none were seen on any of the plants further up or down along the road. By this time, we’d spent about an hour and decided to finish the additional 2-hours drive needed to get to Jacob Lake.

Some of the western U.S.’s worst fires this season occurred on Arizona’s Kaibab Plateau. The Dragon Bravo Fire destroyed over 100 structures on the Grand Canyon’s North Rim—including the historic Grand Canyon Lodge and the North Rim Visitor Center, while the White Sage Fire simultaneously burned significant areas of Kaibab National Forest north and east of Jacob Lake. It was the latter that, unfortunately, swept across both of the sites where I had placed traps a month earlier in June, so I was not optimistic about the likelihood that they had survived. Fortunately, the fires did not reach the immediate vicinity of Jacob Lake, so the campground was unaffected and—unusual in my experience—nearly devoid of people. After setting up camp, I went back north into the burn zone to see if my traps 1) had survived and 2) could be retrieved. The area around the site was almost completely destroyed, with charred black skeletons of trees dotting blackened soils devoid of any vegetation.
Aftermath of the White Sage Fire in the Kaibab National Forest.
I had low expectations for the traps at this site even before the fires, as the area had already burned several years early and was in the early stages of recovery (I had decided to place traps here anyway because I wanted to see what the woodboring beetle fauna in a recovering area might look like).
Blackened trunks punctuate a stark landscape.
I continued walking the 2-track toward the trap location surveying the damage, came around a bend, and saw it—a lone, still-green pinyon pine with my jug trap hanging from a branch and a bottle trap, its yellow funnel only slightly heat deformed, still planted in the soil beneath the tree!
A lone green tree amongst the destruction—with my traps in the tree and below it both intact!
At first I was elated, but then I saw the jug trap reservoir was dry and almost completely empty save for a few dried beetle carcasses—the trap had survived the fires, but the associated winds had blown the trap and dumped the contents (none of which could be detected on the ground beneath). The bottle trap, on the other had, looked to be full of insects with plenty of liquid still in the reservoir, so I was hopeful that I would retrieve some good specimens from it. This proved to be the case (sort of!) as I pulled a few Anthaxia sp., a meloid, and lots of bees (for Mike) from the trap. The dried carcasses in the SRW-baited jug trap turned out to be an elaphidiine & several silphids.
After leaving the first trap site and driving towards the second (a few miles east of Jacob Lake), I saw little to no fire impacts as I continued east of Jacob Lake. However, as I got closer to the site I began to see impacts—first along the ridge above, then down the slope and engulfing the area where I had placed my traps. Fortunately, the fire did not seem to have been as severe in the immediate area, so I remained hopeful.

The bottle trap was found first and was in much the same condition as the bottle trap at the previous location—it’s blue funnel slightly heat-deformed, but the reservoir was filled with liquid and insects. Later sorting yielded an Acmaeodera diffusa?, a Melanophila sp., a couple of Anthaxia sp., a clerid, and lots of bees (for Mike). The Melanophila sp. was especially welcome—known collectively as “fire beetles” for their attraction to active fires, its presence in the trap may have been been a direct result of the fire. The SRW-baited jug trap was quickly found next, and much to my relief the trap was not only intact and undamaged but also filled with insects (in fact, the propylene glycol had not even completely dried). Later sorting would yield only a single longhorned beetle (plus a silphid and a Euphoria inda), but that longhorned beetle would prove to be the catch of the trip—Calloides nobilis mormonus! I have reared a single individual of the nominate subspecies from fire-damaged oak collected in Missouri, so I suspect the presence of this beetle is also a direct result of the fires that swept through the area—a satisfying irony.

Back at camp and after another “surf & turf” dinner of sirloin steak and salmon, I did my customary nighttime walk to look for night-active beetles on the ground and in tree trunks. I had good luck with this here back in June, finding a Zopherus uteanus and several other beetles, but tonight’s catch consisted of just a single Temnochila sp. (family Trogosittidae) and a single weevil (superfamily Curculionoidea) crawling on the large trunks of Pinus ponderosa.

Day 8
I’d seen a fair amount of Ericameria nauseosa (rubber rabbitbrush) in bloom at the second site the previous day when I retrieved my traps but didn’t see any insects (or, at least, beetles or bees) on them. I figured this was due to the early evening hour, so we decided to come back during the day to try again. The E. nauseosa flowers were still, puzzlingly, devoid of insects (save for honey bees and enormous numbers of a large, black, bristly tachinine fly—possibly Archytas metallicus or Juriniopsis adusta).

Like at Kyle Canyon, the absence of Crossidius spp. on E. nauseosa flowers was surprising, as I have seen them on this plant at almost every other location I have ever checked. You can’t make things appear no matter how hard you look, however, so we continued into some openings farther up the slop and encountered a few other plants in bloom. One was Dieteria canescens (hoary tansyaster), on the flowers of which I found a few small beetles of an unknown family. Nearby I saw several dead main branches in a clump of Quercus gambelli (Gambel oak)—cutting into them revealed a very small woodboring beetle larvae, so I collected several of the stems for rearing. Coming back down the slope I found a single cryptocephaline on the flower of Eriogonum racemosa (redroot buckwheat) and a single Acmaeidera rubronotata on flowers of Gutierrezia sarothrae (broom snakeweed)—the latter on which Mike had also found a single Crossidius discoideus. (This seems to be the first record of any species of Crossidius from the Kaibab Plateau! Maybe the other species are here as well but are not quite out yet at this relatively early date in fall.)
Crossidius discoideus (family Cerambycidae) collected on flowers of Gutierrezia sarothrae (broom snakeweed).
We were getting ready to leave when I spotted a large, fallen Pinus ponderosa (Ponderosa pine) with the twigs brown but still attached (indicating it might be the right “amount” of dead to host woodboring beetles. Damage by such could be seen on the smaller branches, and cutting into them confirmed the presence of larvae and led to a second wood-cutting/bundling session to bring the beetle-infested twigs and branches back for rearing.
Chasing more floriferous pastures, we went back up to higher elevations and stopped at a spot close to the campground where we 1) saw a great diversity of plants in bloom and 2) could safely pull off the highway. A huge diversity of blooming plants were seen (from which Mike collected ~20 species of bees), but the only beetles of interest that I saw and collected were numerous small black/red cryptocephalines on the flowers of Eriogonum racemosum (redroot buckwheat). After Mike was satisfied he’d sufficiently sampled the diversity of bees at the site, we looked for another place to collect.
We drove south towards DeMotte Campground on Hwy 67, but much of the landscape was complete devastation due to the fires and no access was allowed beyond Kaibab Lodge. It was depressing to see the immense scale of destruction and loss of natural resources, but as one forest worker that Mike talked to put it, “It’s just trees, and he didn’t have to call anybody’s family [i.e., there was no loss of life].” We then drove back down past my second trap location where we had collected earlier in the day to see if we could find better stands of Gutierrezia sarothrae (broom snakeweed) on which to look for more Crossidius discoideus (still represented in the area by the single individual Mike had collected earlier). We drove through even more complete and utter destruction but eventually found undamaged areas at about 6600’ elevation. Not only was there G. sarothrae in bloom, but also Chrysothamnus visicidiorus (green rabbitbrush) and Ericameria nauseosa (rubber rabbitbrush)—all three species serving as hosts for various Crossidius and providing a perfect scenario for comparing and contrasting the sometimes-tricky-to-identify plants! The promise of Crossidius, however, would not be realized, and after an hour of searching—finding only a lone weevil on the flowers of E. nauseosa—did I finally admit defeat and concede that Crossidius from this after would have to come some other time.

I hadn’t planned to do my customary nighttime walk this evening—my motivation waning after the less than meager success of the previous night, continuing relative absence of beetle life I’d seen during the day, and temps now dropping towards the 50s. A cute but shy Uinta chipmunk in our campsite captured my photographic interest as we relaxed, and the setting sun turned the clouds a stunning pink!

However, as night fell the siren song of the nighttime walk began singing its tune and I was unable to resist.

It turned out to be a more successful night than I’d expected—I found a small species of tenebrionid [Edit 10/1/25: Eleodes pimelioides] on the rocks surrounding the campsite, and there turned out to be dozens of the little buggers crawling though the pine duff in the campground.

Nothing else was seen, however, and since tomorrow would be a long travel day I called it an early night.
Day 9
On a mostly travel day, we tried to take a big bite out of the many miles that still separate us from St. Louis, where we planned to be in three days time. We got another look at the devastation east of Jacob Lake before reaching the dramatic drop off the Kaibab Plateau and down into the Vermilion Cliffs National Monument—their massive red bluffs accompanying us all the way to Mojave Canyon. Just south of there as the highway climbed up and out of the valley, we made a quick stop to remove excess clothing (having gone from high elevation to low), and alongside the road I spotted a Crossidius pulchellus on the flowers of Gutierrezia sarothrae (broom snakeweed). This is the furthest southwest I have collected this species, and I was tempted to continue looking to see if I could find the other G. sarothrae associate—C. discoideus—as well. We still had a long drive ahead of us, however (destination Mills Rim Campground in northeastern New Mexico), so I resisted temptation and we continued the drive.
The Vermilion Cliffs, stunning as they were, still weren’t the highlight of the drive. That honor would come from the moonscape formations along Hwy 89 as it followed the Echo Cliffs and then turned east onto Hwy 160 towards Tuba City. We then passed through a series of stunning plateaus and drops on Hwy 264 as it passed through the Navajo and Hopi Reservations. One abandoned house as we dropped down off the Ganado Mesa was especially picture-worthy.

Eventually we crossed the state line at Picture Rocks into New Mexico, and, suddenly, the landscape seemed more “tame” and less hostile. I don’t normally like interstates, and the stretch of I-40 to Albuquerque did nothing to change my opinion of them, but I must admit that I-25 north towards Santa Fe was among the most picturesque I have ever seen. Eventually, we left the mountains and found ourselves once again on the western edge of the Great Plains—its vast featureless expanse a true contrast to the landscape we had witnessed throughout most of the day. This apparent homogeneity, however, is misleading—tucked away in places unknown to most are some remarkable natural areas, and Mills Rim is one such place. We arrived after dark, so the explorations of its hidden charms would have to wait until the next day, but after getting camp set up I did a short nighttime walk to see what was out and about.

Only one beetle, Stenomorpha sp. (family Tenebrionidae) ambling across the ground, was seen.
Many plants in bloom were also seen however, so I went to bed optimistic about my prospects for finding beetles the next day.
Day 10
Mosquitoes were bad during the previous night, and they were bad again the following morning, prompting liberal use of repellent to a much greater degree than I am used to. At the same time, the presence of mosquitoes indicates abundant moisture in an area, and it was with that optimism that I set about searching for jewel beetles, longhorned beetles, tiger beetles, and whatever other insects could catch my eye in this hidden jewel of a place. Surrounded by treeless grasslands (and preserved as the Kiowa National Grasslands), Mills Rim Campground sits at the edge of Mills Canyon—a chasm in the landscape at the edge of a plateau bordering the foothills of the Rocky Mountains. Firmly embedded in the Great Plains, the juniper/pine/oak woodland at the edge of and down in the canyon features plants and animals at their easternmost extent—residents of the Rocky Mountains that have found an isolated home in the middle of the grasslands. Pinus edulis (Colorado pinyon pine), Pinus ponderosa (Ponderosa pine), Juniperus monosperma (one-seed juniper), Juniperus scopulorum (Rocky Mountain juniper), Quercus grisea (gray oak), and Quercus × undulata (wavy leaf oak) all make their homes here, hosting innumerable insect species that are normally more at home in the Rocky Mountains.

I’ve collected here several times and recorded many different western species of beetles, but the height of the season seems to be in June and July. Mid-September, in contrast, seems to be near the tail end of the season, the numbers and diversity of beetles and other insects dropping from their highs earlier in the season. The flowers of Gutierrezia sarothrae, however, were hosting lots of insects. In addition to Crossidius pulchellus, Chauliognathus basalis, Bothrotes canalicularis, and Collops sp., Mike found numerous bee species, mostly females, collecting pollen from the flowers.

A couple of species of robber flies—Ospricerus sp. and Efferia sp.—were also taken in flight, presumably patrolling the flowers of G. sarothrae for bee prey.

After a rest and rehydration break, I followed the road down Mills Canyon as it approaches the Canadian River to see if I could find Ericameria nauseosa—should I be able to, it would surely be at or near the easternmost limit of occurrence for the species in this part of New Mexico.

A bit further down Mills Canyon Road.
About half a mile down the road I began seeing Acmaeodera rubronotata on the flowers of G. sarothrae, and I eventually secured a series of about a half dozen specimens. This is a nice record, as I found a single specimen a couple of years ago at Black Mesa in northwestern Oklahoma—a new state record and northeastern range extension, and this record helps bridge the gap between that record and the species’ more normal range of distribution across New Mexico and Arizona. Finally, nearly a mile into the canyon, I found one large blooming E. nauseosa and a smaller pre-bloom plant, but there were no Crossidius beetles on them, nor were any additional plants were seen a hundred yards or so further down the road, so I turned around.

On the way back out of the canyon, I collected a Calopteron sp. (family Lycidae) on senescing Melilotus alba (white clover) and photographed a female Stagmomantis limbata (Arizona mantis—family Mantidae).

Back at camp, a couple of scarabaeoid beetles flew to the light of the lamp while we were relaxing with refreshments in hand and waiting for the coals to be ready. This suggested that maybe conditions were favorable for setting up the ultraviolet lights to attract other insects.

After finishing dinner, we did exactly that and saw a few interesting insects show up, but shortly after setting up the lights the wind began to kick up, the temps began to drop, and increasingly frequent gusts making further lighting impossible!

Day 11
It was a rather sleepless final night in the tent—winds whipped as we turned in for the night, and shortly afterwards we awoke to rain splattering our faces through the fly-less tent roof. We quick got up and put on the rain fly, then listened to light but steady rain for most of the rest of the night. By the time we got up it had mostly stopped, but cool conditions with low-hanging, fast-moving clouds caused us to quickly break camp and save coffee and breakfast for Mocks Coffee Shop in Clayton, New Mexico near the Oklahoma state line (let me tell you how difficult it was for me to drive two hours first thing in the morning without coffee!). We had wanted to make our final collecting stop at a a lot near Kenton in the Black Mesa area of extreme northwestern Oklahoma, but the forecast for the area showed only slightly warmer temperatures and very gusty winds. This would make collecting there pointless, so we instead traveled four more hours east to get in front of the cold front at another of our favorite collecting spots, Gloss Mountain State Park in Major Co.

I was hoping to see an attractive late-season jewel beetle—Acmaeodera macra, which I had collected here and at nearby Alabaster Caverns State Park in previous years during late September. Temps were good (well over 80°F) when we arrived but the hour was already late (near 4:00 p.m.), so we had limited time for collecting before insects would start bedding down for the evening (usually around 5:00 to 6:00 p.m. at this point in the season). Megatibicen dorsata (bush cicada) and Neotibicen aurífera (prairie cicada) males were still singing abundantly, filling the air with their distinctive songs (video of M. dorsata male singing here).

Helianthus annuus (annual sunflower) and Grindelia ciliata (wax goldenweed) were blooming prolifically, off the flowers of which Mike collected a fair diversity of bees. I’d hoped to find beetles on the flowers as well, but they were limited almost exclusively to Chauliognathus limbicollis.

I did collect a male/female pair of Tetraopes femoratus (red-femured milkweed borer) on the seed pod of Asclepias engelmanniana (Engelmann’s milkweed) and photographed the striking and beautiful caterpillar of Schinia gaurae (clouded crimson moth) on the stem of Oenethera glaucifolia (false gaura).

After that, I went up on top of the main mesa where I expected A. macra to occur. Heterotheca stenophylla (stiffleaf false goldenaster), on the flowers of which I collected A. macra in previous years, was blooming abundantly, but intense searching their flowers produced no beetles. I also noticed that Gutierrezia sarothrae (broom snakeweed), abundant in the area as well, was in only the earliest stages of bloom, suggesting to me that it might still be a bit too early for the jewel beetles to be out. By the time the 6:00 hour arrived, insect activity was noticeably diminished, and we wrapped up this, our final, collecting stop of the trip.
No camping is available at Gloss Mountain State Park, so we knocked out another hour and a half of travel by driving to Ponca City in north-central Oklahoma and taking a hotel there. For the first time since we left, we enjoyed dinner at a restaurant (fried catfish for me!), a hot shower, and a real bed!
Day 12
The following morning, we were surprised to learn that the only coffee shops in town were Starbuck’s and drive-throughs. This just wasn’t going to cut it for us on our final travel day, so we drove 15 minutes north to the small town of Newkirk and enjoyed great coffee, breakfast sandwiches, and scones at “Savvy Cactus” (Newkirk Mercantile Boutique & Espresso Bar). (The coffee was good enough that I bought a bag of their coffee!)

The rest of the drive back to St. Louis was spent reflecting on the many experiences we’d just had and synthesizing the new knowledge while enjoying the landscape as it skirted the southern edge of the Flint Hills of Kansas and traversed the familiar hills and dales of our beloved Missouri Ozarks—the end of a 3,931-mile trip!
A tobacco hornworm (Manduca sexta) caterpillar that has been parasitized by braconid wasps (Cotesia sp.). The wasps developed inside the caterpillar as grubs, consuming all but the most vital of organs to avoid killing it before they completed their development. They then exited the caterpillar’s body and spun small white silken cocoons in which to pupate and eventually emerge as adults. The adult wasps have already emerged, and though the caterpillar is still alive, it will die before it can complete its development and become an adult moth. The caterpillar was photographed at night in front of a so-called “supermoon” rising in the eastern sky. This is a single exposure image—-not a composite photograph—with the camera focused on the caterpillar (illuminated by flash) but its settings adjusted to also detect ambient light from the distant moon. The moon is necessarily out of focus due to depth-of-field constraints. Photographed 11 Aug 2014 in Mississippi Co., Missouri at the Hwy 62 bridge over the Mississippi River.
Honorable Mention (Plants and Fungi)
A single blossom on the inflorescence of clasping milkweed (Asclepias amplexicaulis). This uncommon species is scattered throughout Missouri but is especially fond of habitats with dry sand substrates. It can be easily identified by its erect, glabrous stems, sessile, clasping leaves, and pinkish flowers. Photographed 23 April 2012 in Scott Co., Missouri at Sand Prairie Conservation Area.
It’s been a few months since I’ve been on a WGNSS field trip, so I was anxious to attend this past weekend’s joint trip between the Entomology and Nature Photography Groups to visit a private restored tallgrass prairie remnant located in extreme southwestern Washington County and named after Henry Schoocraft, who famously chronicled his journey through the Missouri Ozarks in the early 1800s and passed within a few miles of this spot (if you’ve not yet read Schoolcraft’s journal, I highly recommend this natural history classic!). The landowner, a restoration ecologist for Shaw Nature Reserve, has been using prescribed burns and selective thinning over the past several years to restore the 70-acre tract of upland forest, former cropland, and grassland remnants to their presettlement character. Stupidly, I did not bring my main camera, preferring to focus instead on collecting rather than photography. In hindsight, I would have been much better served had I had my camera, as the beetle groups that I study (Buprestidae and Cerambycidae) tend to be scarce at this time of season in Missouri, while interesting subjects for photography in other insect groups abound. As far as photos go, my iPhone would have to suffice.

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

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

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

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

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

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

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

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

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

We were fooled, however, by a tiny species of “tiger beetle” that, upon closer inspection, proved to be a shore bug (Pentacora signoreti—family Saldidae).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

It was a long drive between Eddy Co. and our first collecting spot of the day, and we stupidly made it even longer by going all the way back to Roswell to restock on groceries for the coming week. While we were there, we decided to each lunch at a restaurant instead of out of the car—further adding to our travel time (but the burritos from Burrito Express were so good!). The last leg from Roswell to near Mayhill was—like last time—the worst, with temperatures soaring up to 100°F and the landscape providing so very little of interest.
Carr Canyon Rd Lincoln National Forest Otero County, New Mexico We arrived at about 4:30 pm—still plenty of time to collect and, if we didn’t like what we saw, move on, and we were happy that the higher elevation was providing some temperature relief. We had come to this spot last time based on a prior record of a rather fine buprestid species (Buprestis prospera) from the area, but it was bone dry at the time and we moved on without even getting out of the vehicle. Conditions seemed much better this time, but still I saw no pinyon pine (the larval host) to inspect—and certainly no dead ones to chop into. We were here, however, and decided to give it a shot. I did find a few small dead Juniperus deppeana (alligator juniper), but beating them produced only a single Anomoea sp. (likely an incidental association). The scrub oaks (not sure which Quercus species they represent) as well were leafing out nicely, but sweeping them produced only a smattering of Chrysomelidae (leaf beetles), Elateridae (click beetles), and Curculionidae (weevils)—no Buprestidae (jewel beetles) or Cerambycidae (longhorned beetles). A dry creekbed ran through the area, and I noticed rather lush growth of grassy vegetation in and alongside the creekbed. Recalling that I’d swept such growth along the roadside in nearby Mayhill a few years ago and got a series of Taphrocerus schaefferi, I began sweeping. This was much more productive—each sweeping pass produced one or two Taphrocerus (will need to examine closely to determine if they also represent T. schaefferi, also that is likely), and by the time I finished I had a nice little series of around eight individuals. Checking back with Rich, neither he nor I were seeing much else of interest, so we decided to continue on to the next locality near Cloudcroft.
Pasimachus californicus (California warrior beetle—family Carabidae) in montane coniferous forest.
Switchback Trailhead Lincoln National Forest Otero County, New Mexico The threatening clouds that had just started appearing as we were leaving the previous spot developed into full-blown rain showers as we continued up the mountains to Cloudcroft. Just as quickly as they had come, however, they abated and we arrived to this spot under broken clouds and cool early evening temps. Of all the locations where I had placed traps, my expectations were lowest for this one due to its combination of high elevation (nearly 9000’) and dense, coniferous forests (wine-based baits typically do not attract beetles associated with conifers). I went ahead and placed traps here, however, because 1) I already had several sets at lower elevation woodlands, 2) the presence here of Quercus gambelii (Gambel oak)—a high elevation oak that could be hosting a variety of interesting beetle species, and 3) perhaps the ethanol component of the bait might still attract conifer associates. What I found was completely unexpected—all three traps contained several species of Cerambycidae, none of which I immediately recognized to species! The most abundant species appears to be a large, blonde lepturine, and there was also a smaller Stenocorus sp. as well as a few even smaller species that will require closer examination to identify. I was happy to see all three traps not only still hanging, but also with a little bit of bait still in the bottle and the propylene glycol in the reservoirs not completely dried out. This is in contrast to the traps at all the other lower-elevation localities, which exhibited bone-dry bait bottles and little to no propylene glycol remaining in the reservoir. The thought occurred to me that perhaps the reason these traps were so much more productive was because they remained attractive for the entire one-month period following their placement, while traps at other localities dried up after two or three weeks and failed to attract beetles during the latter part of the period—potentially after beetles had begun to appear in numbers. On the other hand, the very different habitats could also easily explain such a difference. As for the traps, expectedly the SRW/EtOH trap had the largest catch volume, the EtOH-only trap had the smallest (though still good numbers and variety of beetles), and the SRW-only trap volume was in between. Sadly, the white bottle trap was not only pulled out of the ground but completely missing—I can only guess that one of the many hikers that pass through the area saw it and couldn’t resist their inner vandal. The lateness of the hour precluded much further collecting, but I noticed a couple of Anthaxia (Haplanthaxia) caseyi on flowers of Rosa woodsii (Woods’ rose). Based on locality and their dark coloration, they should represent the subspecies A. c. pseudotsugae—unlike the bright green individuals of the nonimate subspecies found further west in California.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

These would be the last insects that I would collect on the trip, and what a final duo they were! On the way back to the car, I picked up a couple of cerambycid-pruned branches of Q. × undulata that I had set aside earlier for rearing. It will be interesting to see if it is the same species that is pruning the two oak species (Q. × undulata and Q. mohriana). With dusk approaching and us still needing to get to the state park and setup camp, we decided that three hours of collecting at the final spot was a good way to close out 10 straight days of collecting!
Black Mesa State Park Cimarron County, New Mexico Our “favorite” campsite in the park was unavailable—in fact, the entire West Canyon campground was closed due to installation of a new dump station for the nearby RV campground. As an alternative, we secured a spot at the nearby Lake Etling Campground. I’ve never stayed there because there are no toilets, but the sites are much larger and come with shelters over the picnic tables—something that would have come in handy during my several previous visits with rain. Site #24, in particular—located at the far end of the campground, nestled up against a low cliff, and well out of sight from the rest of the campground, may well now be my new favorite campsite at the park.
Charcoal “fireworks”!
After enjoying a celebratory rib-eye steak dinner, I walked the roads hoping to see night-active beetles. Unfortunately, the same rains that killed the possibility of setting up the lights also apparently kept the beetles holed up, and I saw nothing. It occurred to me then that this was my tenth visit to the park in the past three years, and it has rained on six of those visits! So much for western Oklahoma being a “dry” place!
A final campfire!
Day 11
The drive from Black Mesa to St. Louis was predictably boring and unfulfilling. Normally I would eschew interstates and divided highways in favor of backroads, but at 12 hours even on the quickest route I had to bite the bullet. At least we did not have to get out of the car while the hottest temperatures of the trip (111°F!) settled over us, and the memories of the trip will feed my souls for a long time to come.
The highest temperature of the trip—111°F! Thankfully, this occurred during the drive home!
In late August, I made another trip out to northwestern Oklahoma to service “jug traps” and other insect traps placed at several locations throughout the area. The traps were set in mid-May (see “First insect collecting trip of the season”), checked for the first time in mid-June at the beginning of a 3-week long collecting trip to the southwestern U.S. (see “2023 Southwestern U.S. Collecting Trip iReport”), and checked again in late July (see “July “jug trap” run”). This post describes the third trip to service the traps—less about what the traps themselves had caught and more about other insects seen and collected at the locations where the traps have been set. The final trap run will be made in early October, and you can expect a post about that trip as well shortly afterwards.
Day 1 — 28 Aug 2023 Alabaster Caverns State Park Woodward County, Oklahoma
Finally a nice break in the weather. Rain moved through a few days ago and temperatures are decidedly lower than the mid-90 to low-100 temps that have dominated for the past few weeks. I started out in the shortgrass prairie along Raptors Roost Trail above the canyon. Last time I was here (5 weeks ago), the only cicadas I heard were Neotibicen superbus (superb dog-day cicada). This time I heard three different species: Neotibicen auriferus (plains dog-day cicada), Neotibicen pruinosus (scissors grinder dog-day cicada), and Megatibicen dorsatus (prairie cicada). I was able to snag one of the former but couldn’t get M. dorsatus—the one I really wanted. There were no Acmaeodera in the white bottle trap—just one Elateridae (and some bees for Mike). Robust patches of Helianthus annuus (annual sunflower) were in flower in the prairie—I checked the flowers hoping maybe some of the fall beetles I was interested in (Acmaeodera macra and Crossidius pulchellus) would be out by now, but all I saw on them were Epicauta sp. (blister beetles), Chauliognathus limbicollis (soldier beetles), and Atalopedes campestris (sachem skippers).

After that I went down into the canyon to check the traps. All of them were completely overloaded—primarily Elateridae and Cotinis nitida. Field counting was impossible, so I bagged for counting later (I did see a few specimens of Plinthocoelium suaveolens and Eburia quadrigeminata/haldemani in the morass) and went down to the campground to set up camp and cook some dinner.
Euphorbia marginata (snow-on-the-mountain, smoke-on-the-prairie, variegated spurge, or whitemargined spurge—family Euphorbiaceae) in shortgrass prairie.
I debated whether to setup the lights (ultraviolet/mercury-vapor)—the moon is waxing towards full (which, by the way, will be the 3rd brightest full moon of the year), and though warm today (not hot) there was a tad of a cool crispness in the air down in the canyon as the evening progressed—good my my comfort but not so good for beetles! I set them up anyway (because that’s what I do), and for the first hour it was a steady accumulation of moths and a few crummy scarabs.
Tent, table, lights, and a large overhanging branch—the perfect campsite!
Eventually I ended up with a single alkali tiger beetle (Eunota togata globicollis—absent where I’m from but quite common in the Great Plains, but nothing else came after that and we’ll into full darkness. I did get a bonus—a dead male Neotibicen pruinosus lying on the picnic table on the campground.

Day 2 — 29 Aug 2023
Sleeping temps were really nice, but I was awoken at 3:40 am by light rain and had to get up and put on the rain fly. It dumped soon afterwards, but I slept nicely anyway. In the morning first thing I found a Epicauta conferta blister beetle—beautifully marked with red on black, and after breakfast and breaking camp I checked the Lindgren funnel trap. On the way to the trap, I came across about a dozen more E. conferta on the road—all feeding on the fallen fruits of Sideroxylon lanuginosum (gum bumelia).

Like the jug traps yesterday, the Lindgren funnel trap was overwhelmed by mostly click beetles but did also contain Eburia haldemani/quadrigeminata and Plinthocoelium suaveolens in the mix. The trap contents were bagged unsorted for counting later.
Gloss Mountain State Park Major County, Oklahoma
There was even more Helianthus annuus (annual sunflower) in bloom here than at Alabaster Caverns (I’ve not seen this here since I haven’t been here much during this time of season), it they were simply loaded with Megatibicen dorsatus (bush cicada). I collected a half dozen from a single clump (and there were four more that flew away while I was doing so) and recorded one male singing. As it sang, a female flew to the plant, and the male then slowly backed down the stem and positioned itself directly opposite from the female, allowing me to photograph the pair together (before the female then flew off abruptly—I guess she didn’t get the right “vibe” from the male).

Right next to the patch of sunflowers i was working, I saw (and caught) a male Neotibicen auriferus singing in Prosopis glandulosa (honey mesquite. I would end up with about a half dozen and record one male singing over the next few hours.

Walking the road into the park to check the lower traps, I encountered a few colonies of Vanduzeea segmentata on H. annuus being tended by ants.

The white bottle trap had a single Acmaeodera sp. and a few other miscellaneous beetles (and 5 bees for Mike), and, as at Alabaster Caverns yesterday, both the SRW and SRW/EtOH traps (the EtOH trap was removed last time) were overwhelmed with Elateridae and Cotinus nitidus beetles and were thus bagged for counting later. However, once again I did see a fair number of Plinthocoelium suaveolens, Eburia haldemani/quadrigeminata, and elaphidiines in the mix. Up on top of the mesa, the jug traps were again overwhelmed and the catch bagged for later counting, and the white bottle trap had no Acmaeodera but several miscellaneous other beetles and bees.

Woodward, Oklahoma
After leaving Gloss Mountain State Park and passing through Woodward, Oklahoma a short distance to the west, I couldn’t resist stopping at my favorite “Christian coffee shop”—sadly closed during my first trip to the area in May but open again under new ownership as a bakery during my July visit.
The coffee is undeniably good, but what I really love about this place is the life-sized dinosaurs in front of the shop, complete with signs giving the true “facts” about dinosaurs from a creationist viewpoint (see “2022 Oklahoma Insect Collecting Trip iReport”). As laughable as the “facts” are, the dinosaurs really are very nicely done (save the angel riding the Stegosaurus!).
Slapout, Oklahoma
Another “must stop” on the way to Beaver Dunes Park is the Slapout Service Station in—you guessed it—Slapout, Oklahoma. The town is (literally!) little more than an intersection, but inside the store is a standup freezer filled with some of the tastiest cuts of packaged meats I’ve ever had. I stopped to pick up a nice filet for tomorrow night’s dinner in the campground at Black Mesa State Park tad a way to celebrate a (hopefully) successful end of the trip.

Beaver Dunes Park Beaver County, Oklahoma
I got here with just enough daylight left to check the traps if I could be quick about it. At the previous spots the traps have been so full that field counting wasn’t feasible, and here was no exception. Although I will eventually have to count them at some point, it does make things go more quickly in the field. I first checked the white bottle trap, which contained a few Acmaeodera sp. and bees, and was able to service all the jug traps and bag their catches quickly with a little bit of time to spare searching the dunes as the sun set in the western sky.
Sunset over Beaver Dunes.
I was looking chiefly for Megatibicen tremulus (Cole’s bush cicada), which was unknown until relatively recently due to the great similarity of its appearance and song to the more common and widespread M. dorsatus (bush cicada) and one that I have not yet seen. This cicada is generally found in more sandy habitats, and there are some iNaturalist records from this area. It didn’t take long, as soon as I hit the 2-track leading into the dunes I saw a male on Helianthus petiolaris (prairie sunflower), and although it looked nearly identical to the M. dorsatus I was catching earlier in the day (at Gloss Mountain State Park) the black rather than brown tymbal covers strongly suggest it is M. tremulus. I saw two more males as I searched the dunes, but both were far too wary and bolted before I could get within net range.

Eventually the settling darkness became too much of an obstacle and I had to return to the car, but as a consolation prize I found a Plectrodera scalator (cottonwood borer) sitting on the upper stem of a sapling Populus deltoides (eastern cottonwood). Right next to the sapling was a much larger cottonwood in which several male Megatibicen dealbatus (plains cicadada) were singing—unfortunately none of which were within net reach (I can’t be too disappointed, as I did collect a couple of them at lights the last time I was here, and I’ve also collected the species in northern Texas).

Day 3 — 30 Aug 2023
No lighting last night—it was too cool and the moon at its brightest. It did make for comfortable sleeping, however (in the middle of the night I had to get into the heavy sleeping bag)! I decided to check out the dunes before heading on to Black Mesa since I had caught only a single Megatibicen tremulus (Cole’s bush cicada) yesterday and wanted to see if I could get a few more. The dunes were bright (and already hot!) in the morning sun.
Beaver Dunes in the morning light.
The cicadas proved to be common enough on the dunes (though not abundant as with M. dorsatus yesterday at Gloss Mountain), but unlike the latter, which were quite clumsy and easy to catch, these were incredibly wary and quick to fly. Less than half the individuals I approached I got within a net swing’s reach (and I have a telescoping long-handled net!), and most of those I could take a swipe at I missed. After more than an hour of trying, I had only two individuals to to show for it—both males singing from the branch tips of Rhus aromatica (fragrant sumac). I did manage to get photos of the one I caught yesterday, which I placed in sumac foliage for the photos, but in cruel turnabout, it got away from me before I could re-secure it! Life is just that unfair sometimes.😊

Even more frustratingly, right as I was swinging the net at one of the two that I caught, I saw right next to the cicada what must have been the large and charismatic buprestid, Lampetis drummondii—a species I have not seen since 1995 when I encountered them rather commonly in western Texas. The buprestid did not end up in the net, nor did I see another individual, so my memory (and this note) will have to remain the only record of the species from this place, at least for now.
1.4 mi E of Kenton Cimarron County, Oklahoma
The jugs traps were not quite as overwhelmed as at the previous locations, and instead of Cotinus nitidus being the abundant scarab it was Euphoria inda. Elateridae were still numerous, but a cursory glance through the catch did not reveal the presence of any Cerambycidae. Nevertheless, the catch from each jug trap was bagged for sorting later. Walking back to the vehicle I encountered two Crossidius discoideus—one hanging out on a grass clump and another flying slowly above the ground nearby. I caught the latter and then tried to photograph the former, but it became quickly alarmed and I had to grab it. After I put it in the vial and went to get the other one out of the net, I discovered it had found its way out and escaped—good thing I had secured the first one! I scanned the plants on the way back to the car but never saw another one.

When I reached the car, I decided to keep searching the area—I had seen a Cicindelidia obsoleta (large grassland tiger beetle)—apparently all black in this area—when I first got here but missed it and wanted to see if I could find it again. It took a while, but eventually I did see another one and got it, and right afterwards I saw yet another one but it got away.

In the same general area as I was looking, I saw something red flying and ran to catch it. It was a Tetraopes femoratus, apparently having just flown from a nearby Asclepias latifolia (broadleaf milkweed).

These new captures induced to me to spend another 45 minutes or so at the site, but I didn’t see a single individual of any of the species I had already collected or any other species of interest. By then it was late enough that I had to leave in order to have enough time to check the final set of traps in nearby Black Mesa State Park.

Black Mesa State Park Cimarron County, Oklahoma
I checked the canyon jug traps first—results were similar to the previous nearby site, with all traps loaded with Euphoria inda and Elateridae. I bagged them for processing later but did see a few Cerambycidae in the catch. The Lindgren funnel trap was also overwhelmed by the same, but since I’m not taking data from the trap I sorted through the catch and picked out 1 Enaphalodes sp., 1 Neoclytus acuminatus, and more than a dozen elaphidiine cerambycids comprising at least two species. While I was servicing the Lindgren funnel trap I found a Stenomorpha opaca crawling in the rocks, and nearby I found another one a short ways down the Overlook road.

The white bottle trap again had lots and lots of bees in it, but unlike last time it also had 8 Acmaeodera sp. plus 20 Meloidae and one Trichodes orestus along with tons of bees for Mike. I saw a few Megatibicen sp. males singing (presumably M. dorsatus rather than M. tremulus due to the non-sandy nature of the habitat) but couldn’t get close to them, and I heard several Megacicada dealbatus males singing in the tall cottonwoods down below by the creek. I think I’ve had my fill of chasing cicadas for now!
After finishing the last of the traps (26 in all at five locations!), I had about an hour of good daylight left and played a hunch that Lampetis drummoni (family Buprestidae) might be out now. I had seen one earlier in the day on Rhus aromatica (fragrant sumac) at Beaver Dunes but missed it, and I reasoned that I might find it in the same here. I took the Overlook Hiking Trail and had walked about half the loop—looking closely at R. aromatica patches along the way (and picking up another Stenomorpha opaca)—and was starting to think it might still be too early in the season (iNaturalist records from the area are all from September and October) when suddenly I saw one perched near the tip of a R. aromatica branch. It was not at all wary (likely due to the lateness of the hour, although my experience with this species in Texas is that they are not particularly zippy), and after taking a photo I was able to pick it easily with my fingers.

I checked the patch carefully and found another four—all perched in the same fashion and not at all inclined to fly off in alarm. I took another photo of the last one I found with a beautiful evening sky in the background, and those would be the only ones I would see for the rest of the hike.
