This is the seventh “Collecting Trip iReport”; this one covering a 5-day trip to Arkansas and Oklahoma from June 7–11, 2019 with my friend and local collecting buddy Richard Thoma. As with all previous “iReports” in this series, this one too is illustrated exclusively with iPhone photographs.
Day 1 – Ozark National Forest, vic. Calico Rock, Arkansas It’s been many years since I’ve visited these sandstone glades overlooking the White River near Calico Rock. Conditions were partly sunny when we arrived, but water on the ground suggested rain earlier in the day. We had only a short time to start exploring before the wind started blowing up and the smell of rain filled the air. I did manage to beat one Amniscus sexguttata from a branch of living Pinus echinata and collect a couple of Strigoderma sp. from Coreopsis lanceolata flowers before steady rain forced us to retreat.
Day 2 – Ouachita National Forest, Winding Stair Campground & Ouachita Trail, Oklahoma We walked the trail from the campground S about 2½ miles and back. I started off with Acmaeodera tubulus on Krigia sp. flowers, eventually finding a lot of them on this plant at higher elevations along with a single Acmaeodera ornata, and I beat a few Agrilus cepahlicus off of Cornus drummondii. This had me thinking it would be a good buprestid day, but it wasn’t, the only other species collected being some Chrysobothris cribraria off of small dead Pinus echinata saplings and Pachyschelus laevigatus on Desmodium sp. Also beat a few miscellaneous insects off of Cercis canadensis and Vaccineum arborea and swept some from grasses and other herbaceous plants. Back at the campground I collected Chrysobothris dentipes on the sunny trunks of large, live Pinus echinata trees.
Ouachita National Forest, Talimena Scenic Dr at Big Cedar Vista, Oklahoma There were lots of native wildflowers like Coreopsis tinctoria and Ratibida columnifera in bloom, so we stopped to check them out. There were lots of butterflies, however, I found only a single Typocerus zebra on Coreopsis lanceolata.
Ouachita National Forest, Winding Stair Campground, Oklahoma We returned to the campground in the evening to do some blacklighting. I had high hopes, but only five cerambycids came to the lights, all represented by a single individual: Monochamus carolinensis, Acanthocinus obsoletus, Amniscus sexguttatus, Eutrichillus biguttatus, and Leptostylus tranversus (the first four are pine-associates). I also picked up a few other miscellaneous insects.
Day 3 – Medicine Park Primitive Campground, Oklahoma There wasn’t much insect activity going on in eastern Oklahoma, so we drove out west to the Wichita Mountains for hopefully better luck. We found a small park with a primitive campground in the city of Medicine Park—my first thought was to beat the post oaks dotting the campground, but when I went into the native prairie between the campground and the creek I never came out! Right away I found what must be Acmaeodera ornatoides on flowers of Opuntia sp., then I found more on flowers of Gallardia pulchella along with Acmaeodera mixta. The latter were also on flowers of Thelesperma filifolium along with Acmaeodera neglecta—took a nice series of each, and I also got a few of the latter on flowers of Coreopsis grandiflora. Strangalia sexnotata were on flowers of C. tinctoria and Torilis arvensis, and then on the latter plant I saw a male Strangalia virilis—a Texas/Oklahoma specialty that I’ve never collected before! I spent the next hour looking for these guys and ended up with 3 males and 2 females along with a few Trichiotinus texanus—another Texas/Oklahoma specialty—and a single Agrilaxia sp. nr. flavimana (could be A. texana). One single Typocerus octonotatus was on flowers of Achillea millefolium. I think we may come back here tomorrow—I’d like to look for more S. virilis and beat the post oaks (the reason we stopped here to begin with).
Lake Lawtonka nr. Ma Ballou Point, Oklahoma We stumbled into this area while looking for stands of Sapindus drummondii (soapberry)—found a small stand along the road, but it was too inaccessible. The same diversity of blooms were present as at the previous spot, so I picked a few longhorns off flowers of Coreopsis grandiflora and Gaillardia pulchella. Super windy, so we didn’t stay long.
Day 4 – Wichita Mountains National Wildlife Refuge, Oklahoma Before starting the day’s collecting, we wanted to go into the Wichita Mountains National Wildlife Refuge to have a look around. On the way into the refuge we some American bison near the road and had to stop, take photos, and simply admire these massive, majestic beasts. We then went to the Cedar Plantation, where I had visited before back in 2012 and photographed black individuals of Cicindelidia obsoleta vulturina (prairie tiger beetle). No tiger beetles were out now (they come out in the fall), but I’d hoped to maybe see Cylindera celeripes (swift tiger beetle) along the 2-tracks in the area. No such luck—nevertheless, we saw a myriad of interesting insects, including several more Esenbeckia incisuralis (green-eyed horse flies) and a beautiful Trichodes bibalteatus (checkered beetle), the latter of which I photographed on flowers of Ratibida columnifera and Achillea millefolium with the big camera. Afterwards we visited the “prairie dog town” and got marvelous views and photographs of black-tailed prairie dogs.
Medicine Park, Jack Laughter Park, Oklahoma We’d noticed this spot yesterday because of the old post oaks and wealth of wildflowers blooming up the mountainside. There wasn’t much going on today, however—just a few Acmaeodera mixta on flowers of Gaillardia pulchella. I did find an Anthaxia (Haplanthaxia) sp. on my arm! Otherwise I spent some time photographing the landscape and some geometrid larvae on flowers of Gaillardia pulchella.
Medicine Park Primitive Campground, Oklahoma We returned to this spot since we had so much luck yesterday. I was hoping to collect more Acmaeodera ornatoides and Strangalia virilis, but there was much less going on today than yesterday—basically didn’t see anything for the first hour and a half. I didn’t give up, however, and kept checking the area where we saw most of the S. virilis yesterday, and eventually I saw another male in the same area as yesterday on the same stand of Torilis arvensis. I found two more males in the same area over the next hour, so three males on the day was a good reward for the time spent looking for them. I also collected Trichodes apivorus and Trichiotinus texanus on flowers of Allium sp. Interestingly, beating the post oaks—the reason why I originally wanted to stop here—produced nothing. So, not very many specimens on the day, but happy with those I did get.
Medicine Park, Jack Laughter Park, Oklahoma I was pretty much done for the day after spending all morning at the refuge and most of the afternoon at the previous spot, but Rich wanted to take another look at Jack Laughter Park because he’d found some interesting grasshoppers there. As with earlier in the day there were few beetles of interest to me, but I did collect a couple of Trichiotinus texanus on flowers of Cirsium undulatum. I checked out some large post oaks with large dead branches thinking that might be what Strangalia virilis was breeding in but never saw any, and eventually I turned my attention to photographing a few interesting native plants that I found along the way.
Day 5 – Epilogue We were tempted to do one last little bit of collecting on the way back to St. Louis, but since had pretty good luck during the last couple of days and the drive alone would take more than nine hours we decided to leave well enough alone and get home at a reasonable hour. A walk with Beauregard when I got home to stretch the post-drive legs was the perfect way to end the mini-vacation.
Hot on the heels of the previous installment in this series, I present the sixth “Collecting Trip iReport”; this one covering a trip to Arizona during July/August 2018 with Art Evans and—like the previous installments in this series—illustrated exclusively with iPhone photographs (see previous installments for 2013 Oklahoma, 2013 Great Basin, 2014 Great Plains, 2015 Texas, and 2018 New Mexico/Texas).
This trip was a reunion of sorts—not only had it been 20 years since I’d collected in Arizona, it had also been 20 years since I’d spent time in the field with Art Evans—which just happened to be in southeast Arizona! For years I looked forward to our next opportunity, and when he told me of his plans for an extended trip to take photographs of his forthcoming Beetles of the Western United States, I couldn’t pass up the chance. Art had already been out west for five weeks by the time I landed in Phoenix on July 28th, and together we drove to Cave Creek Canyon in the Chiricahua Mountains and spent the night before beginning a 7-day adventure in and around the “Sky Islands” of southeastern Arizona.
As with the recent New Mexico/Texas post, the material collected still has not been completely processed and curated, so I don’t have final numbers of taxa collected, but there were a number of species—some highly desirable—that I managed to find and collect for the first time, e.g., the buprestids Acmaeodera yuccavora, Agrilus restrictus, Agr. arizonicus, Chrysobothris chiricauhua, Mastogenius puncticollis, and Lampetis webbii and the cerambycids Tetraopes discoideus and Stenaspis verticalis. Who knows what as-yet-unrecognized goodies await my discovery in the still unprocessed material?!
Day 1 – Chiricahua Mountains, Cave Creek Canyon
After arriving at Cave Creek Ranch late last night, we awoke to some stunning views right outside our room!
The first buprestid of the trip was a series of Pachyschelus secedens on Desmodium near Stewart Campground. We beat the oaks and acacia along the way to Sunny Flat Campground but didn’t find much. Once we got near Sunny Flat I did some sweeping in an area with new growth of Helianthus sp. and got a series of Agrilus huachucae, a few lycids, and one Leptinotarsa rubiginosa. I beat one Acmaeodera cazieri from Acacia greggii and found another on flower of prickly poppy (Argemone sp.). On the roadside at Sunny Flat I found several Acmaeodera spp. on a yellow-flowered composite – one A. rubronotata, one A. solitaria(?), and three A. cazieri. Also collected one A. cazieri on a rain gauge, Mecas rotundicollis and one as yet undetermined acanthocinine cerambycid on miscellaneous foliage, one tiger beetle (Cicindela sedecimpunctata?) on the roadside, and two orange lycids in flight.
Desert flats east of Portal, Arizona
We came to this spot to look for Sphaerobothris ulkei on joint-fir (Ephedra trifurca), but after not finding any for awhile I got distracted by some big buprestids flying around. Caught several Hippomelas sphenicus, one Gyascutus caelatus, and two Acmaeodera gibbula on Acacia rigida, and the first and third were also on Prosopis glandulosa along with Plionoma suturalis. We finally found S. ulkei – searched the area for almost three hours, and Art and I each caught two and Margarethe caught one – also one each of P. suturalis and A. gibbula. I also got a mating pair of A. gibbula on Acacia greggii. After dinner, we went back and placed an ultraviolet light – checked it a couple hours later and got a nice series of Cylindera lemniscata and a few meloids (for Jeff).
Day 1 of the trip ended in typical monsoon fashion – heavy, thunderous rainstorms moved into the area during late afternoon, dimming prospects for blacklighting. Still, we set them up anyway at several spots and checked them later in the evening (flood waters preventing us from going to all the spots we wanted to). Not surprisingly, the one trap that yielded interesting specimens was in the lowest (warmest) area and received the least amount of rain. For me it was a nice series of Cylindera lemniscata.
Day 2 – Southwestern Research Station, Chiricahua Mountains, Arizona
There is a large stand of a narrow-leaved milkweed (Asclepias sp.) at the station, so we stopped by in our way up the mountain to check it for beetles. Got a nice little series of Tetraopes discoideus (tiny little guys!) on the stems as well as a few Rhopalophora meeskei, two Lycus spp., and one Pelonides humeralis on the flowers.
At the Southwestern Research Station with Barbara Roth, Art Evans, and Margarethe Brummermann.
Road from Southwestern Research Station to Ruster Park After leaving the SWRS on our way up to Rustler Park, we stopped to check a couple of bushes of New Mexico raspberry (Rubus neomexicanus). Margarethe thought there might be lepturines on the flowers, but instead we found a few Acmaeodera spp. and some Rhopalophora meeskei.
Further up the road we made another quick stop to check roadside flowers – just a single A. rubronotata on a yellow-flowered composite, but spectacular views of the valley below.
Gayle Nelson once told me about finding Chrysobothris chiricahuae on pine slash at Rustler Park, so I was pleased to see several fresh slash piles when we arrived. I saw a Chrysobothris (presumably this species) on the very first branch in the very first pile that I looked at, but I missed it (damn!) and didn’t see any more in that pile. However, in the next pile I visited I saw two and got them both. I looked at a third pile and didn’t see any, nor did I see any more on the two previous piles that I looked at. Still, two is better than none (assuming this is, indeed, what they are!).
Chiricahua National Monument
Not a bug collecting stop, but we wanted to drive into the monument and see the incredible rock formations which are best appreciated by driving through Bonita Canyon and then up to Massai Point. The unusual spires, columns, and balancing rocks are a result of erosion through vertical cracks in the compressed volcanic ash which was laid down in layers 25 million years ago and then uplifted. Tilting during uplift caused vertical fractures and slippage, into which water then worked its way to create today’s formations. One of the columns I saw is 143 feet tall and only 3 feet in diameter at one point near the base! Mexican jays were our constant, close companions as we hiked through the pinyon pine/oak/juniper woodland.
Vicinity Gleeson, Arizona
There is a wash across N Ghosttown Trail with stands of Baccharis sarothroides growing along the sides. Art previously collected a single Cotinis impia on one of the plants, so we came back to check them. We didn’t find any, but we did find two fine males and one female Trachyderes mandibularis on a couple of the plants. I also found a dead Polycestaaruensis.
Vicinity Tombstone, Arizona
Art saw Gyascutus caelatus here previously, so we came back and found them abundantly in sweet acacia (Acacia rigidula), which was in full bloom. They were extremely flighty and hard to catch, so we each got only four. I also collected one Stenaspis solitaria on the same and a Trachyderes mandibularis female in flight.
At another spot nearby, we stopped to look for Lampetus webbii, which Art had seen but not been able to collect when he was here a couple of weeks ago. We did not see any (but read on…), and I saw but did not collect a Trachyderes mandibularis and two Stenaspis solitaria. I also saw and photographed some giant mesquite bugs (Thasus neocalifornicus).
The day ended enjoying steaks, Malbec, and Jameson with two of the best hosts ever!
Day 3 – Box Canyon, Santa Rita Mountains, Arizona
Our first stop of the day was Box Canyon, a gorgeous, rugged canyon on the east side of the range. Mimosa dysocarpa was in bloom, off which I beat two Agrilus aeneocephalus, several Hippomelas planicauda, and one Stenaspis solitaria. Norm gave me an Acmaeodera cazieri that he’d collected on an unidentified yellow-flowered composite, and right afterwards I found some small, low-growing plants with purple flowers and sticky leaves (eventually ID’d as Allionia incarnata, or trailing four o’clock) to which Acmaeodera yuccavora and A. cazieri were flying in numbers. After that I crawled up top and beat the mesquites, getting one Chrysobothris sp., a mating pair of S. solitaria, and a couple of large clytrine leaf beetles.
Vicinity Duquesne, Arizona
We came here to look for Tetraopes skillmani (this is the type locality). We found the host plant (Sarcostemma sp.), but there were no beetles to be seen anywhere. Maybe another location nearby…
Patagonia Pass, Patagonia Mountains, Arizona We went up higher into the mountains to get into the oak woodland, where I hoped to find some of the harder-to-collect oak-associated Agrilus spp. Right away I beat one Agrilus restrictus off of Emory oak (Quercus emoryi), but no amount of beating produced anything more than a single Enoclerus sp.. I also beat the Arizona oak (Q. arizonica) and got only a single Macrosaigon sp. On Desmodium sp. I collected not only Pachyschelus secedens but a nice series of Agrilus arizonicus. For me it is the first time I’ve collected either A. restrictus and A. arizonicus, the former being quite uncommon as well, so all-in-all not a bad stop.
Sycamore Canyon, Santa Cruz Mountains, Arizona
We came here for night lighting, but while we still had light I did some sweeping in the low vegetation and collected a mixed series of Agrilus arizonicus (on Desmodium sp.) and Agrilus pulchellus – the latter a first for me, along with two small cerambyids that could be Anopliomorpha rinconia. Conditions were perfect (warm, humid, and no moon), and we had lots of lights (Art’s five LED units, Steve’s MV/UV combo setup, and my UV setup), but longhorned beetles were scarce – just one Prionus heroicus and one Lepturges sp. for me, and Steve got a few others including a nice Aegomorphus sp. I did also collect a few scarabs – Chrysina gloriosa and Strategus alous – because they’re just so irresistible!
Day 4 – Prologue One of the downsides (if you can call it that) of having great collecting is the need to take periodic “breaks” to process all the specimens and make my field containers available for even more specimens. Thanks to Steve and Norm for making their place available to Art and I so we can do this before heading out to our next set of localities.
Copper Canyon, Huachuca Mountains, Arizona
Copper Canyon is the classic spot for finding the charismatic Agrilus cavatus (see photo), but first we did some sweeping in the low vegetation near the parking area, where Norm got one Agrilus arizonicus and two Agrilus latifrons – and gave them to me! (Thanks, Norm!) I did some beating of the oaks, and after much work I ended up with a single Agrilaxia sp. and pogonocherine cerambycid on Emory oak (Quercus emoryi) and a couple of giant clytrines on the Arizona oak (Q. arizonicus). I then started sweeping the low-growing Acaciella angustissima – right away I got two A. cavatus. They were in the area past the cattle guard on the right where lots of dead stems were sticking up, and although I continued to sweep the plants more broadly in the area I never saw another one. Finally, Norm called me up to a small Mimosa dysocarpa near the car off which he collected three Agrilus elenorae – and gave them to me! (Thanks, Norm!) I gave the tree a tap and got one more, and in my last round of sweeping I came up with a Taphrocerus sp. (must be some sedges growing amongst the grasses).
Bear Canyon Crossing, Huachuca Mountains, Arizona
There was quite a bit of Mimosa dysocarpa in bloom along the roadsides on the west side of the Bear Canyon crossing, which I beat hoping to find some more Agrilus elenorae. I didn’t find any, but I did get several more Hippomelas planicauda, which is a nice consolation prize – and a great photo of the last one! Other than that I did a lot of sweeping and found only a single Acmaeodera cazieri.
Appleton-Whittell Research Ranch of the National Audubon Society, Elgin, Arizona
Cool temperatures and a blustery wind discouraged most insects from finding our blacklights. However, our blacklight did find some other interesting local residents. These two individuals could be the stripe-tailed scorpion, Paravaejovis (Hoffmannius) spinigerus, a common species in Arizona and southwestern New Mexico.
Day 5 – Miller Canyon Recreation Area, Huachuca Mountains, Arizona
There was a lot of Baccharis sarothroides growing in the lower canyon near the parking area, so I checked it all out hoping to find Tragidion annulatum. None were seen, and in fact there was very little insect life in general. I did pick up a couple of Acmaeodera solitaria by sweeping – not anything significant but the 15th species buprestid of the trip and found a dead Cotinis mutabilis, and Art got a nice series of Chalcolepidius click beetles on B. sarothroides and Prosopis glandulosa. Puzzling the lack of insect activity, given how green all the plants were and how fresh the growth looked. I guess we’ll have to look elsewhere.
Vicinity Naco, Arizona
We decided to try some desert thorn-scrub habitat so headed east towards Bisbee. Just north of Naco we saw some habitat where it had rained recently – everything was green with the sweet acacia (Acacia rigidula) and creosote (Larrea tridentata) in full bloom. Immediately out of the car I found a Dendrobias mandibularis on Baccharis sarothroides (and when I came back to it later I found a big, major male on it – see photos). On the sweet acacia we found a handful of Gyascutus caelatus (one of which I got a nice photo of), a mating pair of Sphaenothecus bivittatus, and a Cymatodera sp. Finally, out along the roadsides a riot of different yellow composites were in full bloom, including Heliomeris longifolia off which Art got a couple of Acmaeodera solitaria and I got two specimens of a large Acmaeodera sp. (blue-black with numerous small irregular yellow spots).
Vicinity Tombstone, Arizona
We decided to go back to the spot north of Tombstone where Art had earlier seen Lampetis webbii and give that species another shot. We looked at the Rhus sp. tree that he’d seen them on, and then we each followed the wash in opposite directions looking at the Rhus trees along them, which growing above the banks but never further away than about 25 feet. Along the way I collected several more Gyascutus caelatus on sweet acacia (Acacia rigida), which were more abundant this time than last and also easier to catch. After walking about 1/4-mile down the wash I saw something fly from a Rhus tree and land low on the bushes nearby. I quickly netted it, pulled it out, and was elated to see that it was, indeed, Lampetis webbii! I searched the Rhus in the area more carefully but didn’t find any more, then found some Rhus growing up along the road. At one point, I saw a large buprestid fly and land high in the top of another Rhus tree. I couldn’t tell for sure if it was L. webbii, but I extended my net as far as I could, positioned it beneath the beetle, and tapped the branch hoping it would fall in. Unfortunately, it flew away instead of dropping, so I can’t say for sure whether it was L. webbii or just a wayward G. caelatus. At any rate, L. webbii is yet another species that I have not collected before now and the 17th buprestid species of the trip.
Ramsey Canyon, Huachuca Mountains, Arizona
After returning from Tombstone, we visited Pat & Lisa Sullivan at their home at the end of Ramsey Canyon. Pat is a scarab collector who runs lights at his home nightly, and after a delicious dinner we spent the rest of the evening checking the lights. I was hoping to collect Prionus heroicus, and I got my wish. Also got Prionus californicus and several other non-cerambycid beetles such as Chrysina beyeri, C. gloriosa, Lucanus mazama, and Parabyrsopolis chihuahuae (the latter a first for me). I also placed a prionic acid lure (thanks Steve!) and got three more male P. heroicus. We also hunted around the rocks and roadsides hoping to find Amblycheila baroni but didn’t find any. Art did, however, find a female P. californicus and gave it to me (thanks!).
Day 6 – Vicinity Sonoita, Arizona
Unsuccessful attempt to collect Hippomelas martini, only recently described (Bellamy & Nelson, 1998) and part of the type series taken somewhere near this spot (“20 mi NE Patagonia, Hwy 82”) by “sweeping roadside vegetation”. At other locations it had been recorded on Calliandra sp., and I found patches of the plant here along and on top of the road cuts. This gives me confidence that I found the right spot, but I didn’t encounter this or any other beetles by sweeping the patches or visually inspecting them.
Box Canyon, Santa Rita Mountains, Arizona
We decided to come back to Box Canyon since we’d had such good luck last time. I started at the spot above the dry falls where I collected so many Acmaeodera cazieri and A. yuccavora on flowers of Allionia incarnata. This time it was hotter, drier, and windier, and the flowers were semi-closed. Still I found a few of each. I then started walking down the road towards the lower canyon crossing where I would meet up with Art. Things were really hopping on the Mimosa dysocarpa, with Hippomelas planicauda abundant (finally collected my fill) and several other Buprestidae also beaten from the plants: Agrilus aeneocepahlus, Acmaeodera scalaris, Acmaeodera cazieri, Chrysobothris sp., and a species of Spectralia! (seven species of Buprestidae at one location I think is the high for the trip.) I checked other plants and flowers along the way down but didn’t find much.
Lower Madera Canyon, Santa Rita Mountains, Arizona
Madera Canyon is perhaps the most famous insect collecting locality in Arizona – maybe in the country, and it is hard to make a visit to Arizona without stopping by here. We elected to work the lower canyon first in an area where Chrysobothris chalcophoroides has been taken on Arizona oaks (Quercus arizonicus). Hiking towards the oaks I found some Stenaspis solitaria in a Baccharis sarothroides and marveled at the variety of other insects active on the plants (see photos) – later I would also collect an elaphidiine cerambycid on the plant. Next I started working the oaks, beating every branch I could reach with my net handle. With one whack of the stick a single Paratyndaris sp. and a single Brachys sp. landed on my sheet – those would be the only buprestids I would collect off the oaks! Other than that I collected one Hippomelas planicauda on Mimosa dysocarpa for the record. While I was working the oaks up in the knoll, the weather started turning with blustery winds, and I could see the rain coming in the distance. By the time I got down from the knoll the rain had arrived, and I walked back to the car in a sunny downpour using my beating sheet as an umbrella!
Montosa Canyon, Santa Rita Mountains, Arizona
Just to try something different, we went to Montosa Canyon – the next canyon south of Madera Canyon – for tonight’s blacklighting. We set my sheet up just E of the crossing and Arts ground units back to the west along a gravel road on the south side of the crossing. Moths came in numbers, but the beetles were light – I collected only blister beetles (Epicauta sp.) and a Cymatodera sp. checkered beetle at the sheet, a series of tiger beetles and a female Strategus cessus at the second ground unit, and a male Strategus aloeus and two Stenelaphus alienus at the third ground unit.
Day 7 (last day) – Vicinity Continental, Arizona
There was a photo posted on BugGuide of Stenaspis verticalis taken last week, so we decided to give it a shot and see if we could get lucky and find it ourselves. We checked all the Baccharis sarothroides within ½-mile if the spot but didn’t find it. I did, however, collect four Euphoria leucographa, two Chalcolepidius smaragdula, two Aneflus spp., and singletons of Stenaspis solitaria and Dendrobias mandibularis. I also took a couple of Hippomelas planicauda on Mimosadysocarpa – just for the record!
Lower Madera Canyon, Santa Rita Mountains, Arizona
We returned to work the lower canyon area. I’d heard that the tiger beetle Cicindelidia obsoleta santaclarae has been taken in the area last week so was hoping to run into it. While Art worked the east side of the road I worked the west, initially following FR-781 into what looked like grassland areas where the tiger beetle might occur. I didn’t see any but took Acmaeodera scalaris on Heterotheca sp. flowers and Acmaeodera solitaria on Argemone mexicana flowers. There was also a fresh wind-thrown mesquite (Prosopis glandulosa) with a bunch of Chrysobothris octocola and one Chrysobothris rossi on it. Still the area looked abused from grazing and was uninteresting, so I looked for another area to explore.
Northwest of the parking lot I spotted another grassy area that was dotted with Baccharis sarothroides, so I decided to give that area a look. After clambering several times through barbed wire fence, I reached the area and began to give it a look. Still no tiger beetles, but every time I passed a B. sarothroides I inspected it closely. I’d looked at several plants when I came upon one with a Stenaspis solitaria sitting in the foliage, and when I looked down on one of the stems and saw a big male Tragidion sp. on the underside of the stem. After securing it, I looked closer at the plant and saw a pair of annulated antennae crawling up another stem – I knew right away it was a mating pair of Stenaspis verticalis! After carefully moving to the other side to confirm, I dared to take a few photos in situ (see below) and then secured the couple. Of course, this gave me newfound motivation to work the entire area to look for more. It was very hot by then, and I was already quite thirsty, but I summoned up all the stamina that I could and worked as many plants as I could, ending up with six Tragidion spp. and three Stenaspis verticalis. The latter was one of my top priority targets for this trips, and the only thing more satisfying than getting it is doing so on my last day on the field.
Montosa Canyon, Santa Rita Mountains, Arizona
We returned to Montosa Canyon and stopped at the Astronomy Vista partway up. It was hotter than bejeebuz! There was not an insect to be seen except giant cactus bugs and a single Euphoria leucographa that Art found on a sapping Baccharis sarothroides. Temp was 103°F even at this elevation!
We needed to escape the heat, and I wanted to see oaks for one more crack at Mastogenius, so we drove up to the 13-km marker and I collected on the way back down to below the 12-km marker. Conditions were much more agreeable (temps in the 80s), and near the top there was a Ceanothus sp. bush in bloom, off which I collected Rhopalophora meeskei and Stenosphenus sp. – both genera represented by individuals with black versus red pronotum. Then I started beating the (Mexican blue, I believe) oaks, and right away I got a Mastogenius sp.! Kinda small, so I’m thinking not M. robusta and, thus, probably M. puncticollis (another species new to my collection). I also beat a largish Agrilus sp. that I don’t recognize, a few clerids, two R. meeskei, one Stenosphenus sp., and a couple of leaf beetles. There was also another type of oak there – Arizona white, I believe, which I beat as well but only got one clerid.
We stopped by the Astronomy Vista again on our way back down the canyon, and I found a pair of Moneilema gigas on cholla (Opuntia imbricata).
It was a fantastic seven days in the field with Arthur, and it was a great pleasure to (in some cases, finally) meet Margarethe, Barbara, Steven, Norm, and Pat. I appreciate the warmth, generosity, and hospitality that all of them displayed to me and look forward to our next encounter, hopefully in the near future. Now, for some light reading during the plane ride home!
This is the fifth in a series of Collecting Trip “iReports”—so named because I’ve illustrated them exclusively with iPhone photographs (see previous articles for 2013 Oklahoma, 2013 Great Basin, 2014 Great Plains, and 2015 Texas). Note that I continue to use my “big” camera for specific insect targets—and these will be featured from time to time on this site. However, I use my iPhone camera much more during these trips for general photography to document habitats, landscapes, and miscellaneous subjects because it is so small and handy and because it is also capable of capturing reasonably good photographs (see this post for tips on making the most of the iPhone camera’s capabilities). This allows me to spend more time looking for and collecting insects—usually my primary objective on these trips! Collectively, these iPhone photos and the short narratives accompanying them form a nice trip synopsis when assembled into a single post.
This report covers a collecting trip I made with Jeff Huether from June 2–9, 2018 to southeastern New Mexico and west Texas. I’ve dabbled in this area before, primarily just a quick stop at Mescalero Sand Dunes many years ago, but not specifically targeted this area for any systematic collecting. Thus, most of the locations that we visited were new to me, which automatically means that I would find at least a few things of interest—and more probably a lot (as long as the insects are active). We had great success at many localities, having found areas where sufficient rain had occurred to trigger insect emergence despite the drought that was plaguing much of the area. Highlights were the areas along Hwy 380 between San Antonio and Bingham, the Mescalero Sand Dunes, and the dunes near Kermit, Texas. I haven’t yet tallied the number of species collected, as much of the material is still waiting to be mounted and identified. However, I estimate that it is in the neighborhood of about three dozen buprestids and maybe half that many cerambycids, including some quite charismatic species that I’d not collected previously (e.g., Prionus arenarius and Tragidion armatum).
Stay tuned, because I made a second insect collecting trip during 2018, this one with Art Evans to southeast Arizona during late July and early August.
Day 1 – Sandia Mountains, New Mexico We flew into Albuquerque this afternoon and, after getting the car, supplies, and something to eat we came up to Sandia Crest Recreation Area looking for Cicindela longilabris (long-lipped tiger beetle). This was the first place I stopped on the first day of the trip for the first species I wanted to look for, and I found it in the first five minutes I was here!
We stopped at the Capulin Picnic Ground on the way down the mountain. There were some oaks with fresh-looking foliage that I beat – no Buprestidae but a nice series of a treehopper (Telamonthe?) and a few odds and ends. There was also Robinia off which I beat a series of what is surely Agrilus egenus.
Day 2 – Walking Sands Rest Area, New Mexico Quick stop to check the lights – later in the season Jeff has collected Prionus palparis here, but this time we saw nothing. Also checked the nearby vegetation, there was Dalea in bloom but no beetles on the flowers.
Hwy 380 between San Antonio & Bingham, New Mexico We saw a few things in bloom at the Rio Grande bridge crossing so decided to stop. I took a fair series of what must be Acmaeodera mixta off of the Thelesperma flowers (along with a few mordellids for Enrico and one meloid for Jeff). Otherwise not much activity at the spot.
There were some cool looking red sand dunes on Hwy 380 east of San Antonio, so we stopped to see if there might be any tiger beetles. There weren’t any, but I found yucca stems infested with cerambycid larvae, likely Tragidion. I collected 6–8 stems to bring back and try to rear out the adults. Jeff also found a single Chrysobothris sp. on sage, otherwise we saw few beetles.
Going east on Hwy 380 we went into an area of higher elevation with junipers. We stopped to check the Thelosperma flowers, but there were no bups on them. I collected a few noisy cicadas and some Acmaeodera quadrivittatoides on Opuntia flowers. I then started beating the junipers, however, and got a fair series of a small green Gyascutus plus two tiny Chrysobothris. They were extremely difficult to collect – winds were very stiff and the beetles were very active. I probably lost as many as I collected. To finish off I found a mating pair of Moneilema sp. on cholla.
In addition the the Tragidion larvae that I collected two stops back, Jeff saw one adult at the previous stop. So, when we saw thick stands of yucca along the roadsides just a few miles down the road we stopped to take a look. They were out and not uncommon on the flower stalks and down in the basal rosettes. I collected about a dozen of them and also another Gyascutus.
At the last stop we noticed a lot of emergency vehicles rushing to the east. Just a couple of miles down the road we ran into an accident blockade. Since we were stopped I was tempted to look at the rock shop, but then I started looking at the cholla and found several Moneilema sp. adults on the plants.
Walking Sands Rest Area, New Mexico We came back up to the rest stop because of the dunes – there are Prionus spp. that live in the dunes, so we put out some pheromone to see if we could attract the males which fly at dusk and early nighttime. In the meantime we walked around looking for nocturnally active beetles – found a few skin beetles (Omorgus sp.) feeding in dried dog poop and a huge tenebrionid (Eleodes sp.) strangely perched up in a bush. Also photographed a cool little sun spider (Solifugida). When we went back to check the pheromone there was one male Prionus arenarius running around under the lure!
Day 3 – Valley of Fire National Recreation Area, New Mexico We came over the hill and saw a huge black area in the valley below. I thought it was just an area of thick woody vegetation, but it was actually a lava field! Very cool. There were tons of cicadas, I think also cactus dodgers (Cacama spp.) but look different from the one we saw yesterday. I beat a lot of Celtis and only got one Chrysobothris sp. (looks like analis), and there was nothing on the junipers. We also didn’t see any Moneilema on the abundant cholla. I did catch two Acmaeodera mixta on an unidentified white flower. I think yesterday’s rains must have missed this area!
I believe this is another species of cactus dodger cicada (Cacama sp.).
We drove a couple miles down the road and made just a quick stop to check flowers along the roadsides. No beetles seen – seems to be super dry, but I did photograph one of the tiniest butterflies (something in the family Lycaenidae) I’ve ever seen.
Sierra Blanca Mountains, New Mexico
Jeff wanted to look for an Epicauta up here, but the whole drive up the mountain we could only comment on how dry it was and how extensively the area had burned. I only found two wood borers – an Anthaxia (Melanthaxia) and a lepturine cerambycid, both on iris flowers. We did find the Epicauta though, also on iris flowers.
Vicinity Sunset, New Mexico There were some mallow in bloom along the roadsides, so we stopped to see if there were any Acmaeodera on them. There weren’t, just a few meloids that Jeff was interested in. I found a a single Euphoria kerni on a flower of Acacia greggii and, of course, large numbers of them on thistle flowers. The area seems to have gotten some rain, but not much activity to speak of yet.
Mescalero Sand Dunes, New Mexico This area got rain last night, so we suspected there would be a lot of insect activity, and we were right! The place was alive when we got here at ~6 pm. I walked the area while we waited for dusk to set out pheromone. I collected a series of Enoclerus zonatus off of yucca blooms, beat an Actenodes sp. (something new for me), a Chrysobothris octocola, and a nice series of treehoppers off of mesquite, and found three Batyle suturalisssp. on an unidentified yellow comp.
As the sun began to sink lower in the sky, I hiked around to the backside of the dunes and then bushwhacked across them to get the perfect perspective for photographs when the sun hit the horizon – spectacular sunset!
By the time I got back to the car, Jeff had already placed three lures out, so we started making the rounds and found at least one or two Prionus arenarius males running frantically in circles under each one. At the second lure, I started searching the area nearby and found a female walking on the ground! (Females are very rarely encountered, and it seems a little more than coincidental to me that for each species of Prionus, whenever we have collected good numbers of males with lures we have also found at least one or a few females in the same area – maybe cheaters [in the ecological sense]?).
As we made the rounds we picked up an amazing diversity of tenebrionids and a few carabids walking in the sand, and we finished off by picking up Jeff’s light trap, which had attracted one more Prionus male and a very light-colored Polyphylla sp. male.
Day 4—Mescalero Sand Dunes, New Mexico
We noticed a stand of soapberry (Sapindus drumondii) along the sides of the road just west of the entrance to Mescalero Sands Recreation Area last night, and I immediately thought of Agrilus sapindi, so this morning on our our way to the dunes we stopped by. I started beating the flowering branches of the larger soapberry trees but wasn’t really getting anything. Then I noticed an A. sapindi flying to a low non-flowering plant, so I caught it and resumed beating – now with more gusto knowing they were here. I still wasn’t getting anything and, again, saw another adult fly and land on a low non-flowering plant. Lesson learned – I started sweeping the low plants and started getting them. I worked all five stands in the area and got about 3 dozen adults, plus a few A. ornatulus, one A. limpiae, and spectacular Neoclytus.
After finishing with the soapberry, Jeff had noticed some tiny Acmaeodera on an unidentified white-flowered composite. We started searching in earnest and collected several dozen adults. I’m not sure what they are, but they are tiny and vittate (maybe A. quadrivittatoides). We also did a lot of sweeping of the short shrubby oak also and came up with a couple of Brachys. Overall a great morning/early afternoon in the field!
We next went into the Recreation Area proper to each lunch, after which we explored the rest of the area accessible by vehicle and saw a stand of cottonwood back in the dunes. We got out to see if there might be any Buprestidae on them (e.g., Poecilonota), but they were devoid of insects. The midday heat on the dunes was extreme! I did find, however, a single Prionus elytron lying on the sand beneath the cottonwoods, so we know they are further back in the dunes as well.
We worked the variety of blooming plants in the vicinity of the entrance. I collected ~22 of the small Acmaeodera that were on the white-flowered plant at the soapberry spot on two blossoms of a single yellow-flowered pad Opuntia sp., a couple of Acmaeodera spp. on Gaillardia sp. flowers, a few more Acmaeodera spp. on Prosopis, and several Acmaeodera mixta on another as-yet-unidentified white flower. It was hotter than bejesus we later learned 103°F!) – I had wanted to check out one more stand of soapberry at the entrance, but we were exhausted and dehydrated and had to quit!
Vicinity Hobbs, New Mexico
We got a hotel in Hobbs and grabbed a sandwich for dinner, then went out west of town to see if we could find some good habitat for evening collecting. We found a spot of open rangeland about 8–9 miles west of town, set out the pheromone lures, and began beating the mesquite (Prosopis glandulosa). We had high hopes because there was still standing water, meaning that the area had gotten good rains on Sunday night. Boy were we correct! Beating the mesquite was amazing. For buprestids I got 10 individuals of an Actenodes sp., 4 individuals of a Paratyndaris sp., 4 Chrysobothris spp., 4 Acmaeodera spp., and 1 Agrilus sp. I also got several tiny cicadas, a couple treehopper species, and a few clerids and other odds and ends. We setup a blacklight and the scarabs were quite diverse, but the only thing I took was a tiger beetle (Cylindera lemniscata). I also picked up a Phyllophaga cribrosa and a tenebrionid walking on the ground at night. No Prionus came to the lures, any my searches of the ground at night turned up no Amblycheila.
Day 5—Sand Dunes near Kermit, Texas
We stopped just outside the Kermit Sand Dunes to beat the mesquite (Prosopis glandulosa) to see what might be out. I collected 8 species of Buprestidae: nice series of an Acmaeoderopsis (hoping A. prosopis), 1 sp. Actenodes, 2 spp. Chrysobothris, 1 sp. Paratyndaris, 1 sp. Agrilus, and 2 Acmaeodera spp. We eventually gave up – the heat had not only wilted us, but the Acmaeoderopsis were flying away immediately upon hitting the sheet.
We drove a little further towards the heart of the dunes and found a spot where there were some blowouts and classic sand flora. Immediately upon starting out we noticed Acmaeodera mixta adults flying around commonly, so I swept through the vegetation a bit and collected a representative series. On Oenethera sp. flowers I found a single A. immaculata and later several A. mixta and a very small Acmaeodera (looked like the one we collected yesterday at Mescalero). In one spot I found a few plants of an unidentified yellow composite with a few more A. mixta, and on Baccharis I found one A. obtusa(?) along with A. mixta. Coming back to the car Jeff and I noticed huge numbers of A. immaculata flying to an unidentified shrub, from which we each swept a nice series. Eventually the heat (103°F) again overwhelmed us, and we had to get in the car, eat, and cool down for a bit on the way to another spot.
We returned to an area with stands of soapberry (Sapindus drummondii) that we had seen when we first arrived in the area. I swept all of the small plants on the east side of the highway and got a single Agrilus sapindi – not nearly as abundant as we had seen at Mescalero Sands.
On the west side of the highway there were some larger mesquite (Prosopis glandulosa). I found one Chrysobothris octocola on the trunk, then Jeff and I noticed Acmaeoderopsis flying to the tips of the high branches. I got my aerial net and just started betting them as they flew in while we stood and watched. I caught them from several trees, but a majority from a single tree. That worked much better than beating this morning – I probably lost as many as I collected because they flew so quickly upon hitting the sheet.
Underneath one large mesquite I found several prionid elytra – couldn’t tell if they were Prionus or Derobrachus, but then I noticed burrows in the ground very similar to those we saw for Prionus integer in Colorado (see photo). We dug a few out but found nothing. Something to keep in mind.
We returned to the dunes for some evening collecting. I beat the two large mesquite (Prosopis glandulosa) trees by the parking area and got an Actenodes and a few Chrysobothris octocola – no Acmaeoderopsis, I guess they hide elsewhere for the night. Once dusk fell we began checking the pheromones and light – only a single male Prionus arenarius came to the pheromone, but we got several individuals of two Polyphylla spp. (P. monahansensis – larger, and P. pottsorum – smaller) at the light. Walking around the dunes at night there were significantly fewer tenebrionids and other insects walking around, but I did pick up two cool “concave” tenebs and a Pasimachus ground beetle.
Day 6—I-10 Rest Area at mile marker 162, Texas
Just a quick stop to use the facilities, but I couldn’t resist the temptation to photograph these three Reakirts blues all on one flower (a fourth flew away before I could snap).
San Felipe Park, near Fabens, Texas We took a chance on going further west to the dunes near Fabens, since we’ve had such good luck with rains in the area. However, when we got here and started looking around it was apparent that nothing was happening here – dry, dry, dry with temps just over 100°F. I saw a few insects but only a single buprestid – Acmaeodera quadrivittatoides, and I missed it! We decided to cut bait and head back east and north towards Carlsbad – we should be able to get to the area in time for some late afternoon and evening collecting. You can’t win ‘em all!
Vicinity Carlsbad, New Mexico After getting lost in the Fabens Sand Dunes and then a whole lot of driving back east into New Mexico, we arrived in Carlsbad with just enough time to grab a sandwich and head out to some promising habitat we’d noticed on the way in for some evening/night collecting.
The area contained a ribbon of woodland with mesquite (Prosopis glandulosa), black acacia (Acacia rigida), and catclaw acacia (A. greggii). I beat only one tiny Chrysobothris sp. off the mesquite, but off the black acacia I beat three individuals (four actually, one got away) of a large, chunky Chrysobothris sp. that I do not recognize, plus an undetermined cerambycid and a few clytrines. Actually, before I collected the Chrysobothris I had given up on the lack acacia until I was walking by one plant and saw the first one sitting on a branch. I popped it in the vial and started beating the other plants in the area with renewed enthusiasm the find the other two (three!).
We setup the lights and the pheromones, but not much came to the former and nothing to the latter (expected, since there was no sand habitat nearby). The sunset beforehand, however, was magnificent, and I did find a couple of miscellaneous beetles walking around at night.
Day 7—vicinity Loco Hills, New Mexico
We saw an area with stands of soapberry (Sapindus drummondii) alongside the road so stopped to sample it for Buprestidae. I got 3 Agrilus limpiae on trees right around the car but nothing on all the rest of the three stands nearest the car on either side of the road. I hope the south area of Mescalero Sands is not as dry as it still appears around here.
Mescalero Sand Dunes, New Mexico
We found the central dunes of the southern area and immediately found several Acmaeodera mixta adults on mesquite (Prosopis glandulosa) flowers. I started beating the mesquite and picked up a nice series of Acmaeoderopsis, one Actenodes, and a few other miscellaneous Acmaeodera off the larger trees. There was some soapberry (Sapindus drummondii) in bloom around the dunes, but beating it produced no Buprestidae.
We stopped at a spot outside the dunes because it looked pretty green with a number of plants in bloom suggesting recent rain. I saw but did not take Acmaeodera mixta on white flowers of undetermined composite. I did collect a small series of bright red and black clerids on a small blue-green euphorbiaceous plant. Also saw a little horned lizard, who cooperated just enough to get a few snaps!
A young Texas horned lizard (Phrynosoma cornutum) tries to make himself look big!
Vicinity Carrizozo, New Mexico
We stopped at a thick stand of yucca that we’d noted on the way past here earlier in the week, the hope being that we would find Tragidion armatum on the stems. Sadly we did not see any, nor did we see more than just a couple of the pompilid wasps that the beetles mimic. Surely this is a result of the lack of rain in the area, which the hotel clerk confirmed during our earlier check in. Cicadas, on the other hand, were everywhere!
The low sun illuminates the yuccas, while the higher clouds shade the mountains behind.
For the final stop for the day we returned to Valley of Fire Recreation Area – not really to collect insects, but to look about this fascinating landscape. The Lava Beds are thought to be 5,000 years old, having formed over a 30-year period when lava poured from Black Peak to the north (not a volcano, but a volcanic vent) at a rate that would fill 15 bathtubs every second! It was a serene and otherworldly walk in the falling darkness – nice way to cap off an evening.
Day 8—vicinity Bingham, New Mexico and west on Hwy 380
We stopped at another yucca stand very near where we’d found the Tragidion armatum last weekend – no problem finding them here either. I got plenty of photographs of the beetles (despite having to go ‘au natural’ with the lighting – my flash unit had died!), as well as of cicadas, wasps, and other insects on the yucca stems and pods. Otherwise I only collected two Acmaeodera (looks like A. immaculata) on flowers of Sphaeralcea sp., what looks to be A. disjuncta/paradisjuncta on Ephedra sp., and a single Moneilema sp. on Opuntia imbricata. Nice stop!
We then stopped by “the juniper spot” again to see if I could get a better series of the Gyascutus (G. carolinensis?) that we found on the junipers (Juniperus monosperma). Boy, did I ever! I collected about 30 specimens this time, made easier by the fact that it was cooler and not nearly as windy! I also again collected two small Chrysobothris sp. on the juniper, a single Moneilema sp. on cholla (Opuntia imbricata), and a single Acmaeoderopsis sp. beating mesquite (Prosopis glandulosa).
We stopped at another spot further west on Hwy 380, where last weekend when we were here we saw few beetles but I did collect yucca stems infested with Tragidion armatum larvae. It rained here later that day, so we stopped by again on our way back to see if the rains had prompted more insect activity. It didn’t seem to, but I did find a Tragidionarmatum adult feeding on a yucca flower and photographed a big-as-heck katydid.
“The Box”, vicinity Socorro, New Mexico
Last stop of the trip – we just wanted to find some habitat to beat around in before finding a hotel in Socorro for the night. I beat a couple of small Chrysobothris sp. from the Juniperus monosperma – no Gyascutus – and a couple of treehoppers from Prosopis glandulosa – no Acmaeoderopsis, then turned my attention to the cholla (Opuntia imbricata), in what must have been the thickest stand of this plant I’ve ever seen. There were two species of cactus beetles on them – Moneilema sp. and Coenopoeus palmeri, the latter a first for the trip. After hiking up to the canyon overlook, I realized that the collecting and fun were finally over (until Arizona in August!).
On my most recent Great Plains collecting trip, cactus dodger cicadas weren’t the only residents of the cholla cactus (Cylindropuntia imbricata) that studded the open grasslands in southeastern Colorado—cactus beetles (Moneilema spp.) also were found, though in lesser numbers than their frenetic, screeching neighbors (perhaps the reason for their scarcity?!). I’ve covered cactus beetles before, posing the question, “How do you photograph cactus beetles?” The answer was, of course, “Very carefully!” That is certainly true in most cases, but not all.
The clumsy, flightless adults rely on their host’s vicious spines for protection.
Cactus beetles are found almost exclusively on opuntioids (chollas and prickly pear cacti), and while most opuntioids are rather viciously spined the plants themselves vary tremendously in structure. Prickly pears (Opuntia spp.), on which I previously photographed these beetles, generally grow in low, dense clumps, their flattened pads often forming a tangle of well-armed hiding places for the beetles. Such is not the case with chollas, which are generally taller, more erect, and have a much more open structure of well spaced, cylindrical stems. The beetles on these plants still enjoy a great amount of protection by the long, barbed spines that cover the stems, but to entomologists/photographers like me they are still much more easily collected and photographed. In this particular case, no special techniques were needed to get nice close-up photos against a clear blue sky other than crouching down a bit and being careful not to lean too close to the plant. That is not to say, of course, that photographing insects on cholla is completely without risk, as this photo showing the spines impaled in my flash unit afterwards will attest (but better the flash unit than poking the lens!).
The hazards of photographing cactus beetles.
The cactus beetle in these photographs appears to be an armed cactus beetle, Moneilema armatum, by virtue of the small but distinct lateral spines on its pronotum, lack of pubescence on the elytra, and relatively smooth pronotum lacking large punctures except along the apical and basal margins. These shiny black beetles occur in the western Great Plains from Colorado and Kansas south through New Mexico, Oklahoma, and Texas into northern Mexico. Adults and larvae seem to prefer chollas over prickly pears—adults feeding on the surface and larvae tunneling within the stems. I suspect the adult feeding helps provide nutrition for egg maturation in addition to creating an oviposition site, and plants infested with larvae often appear unthrifty and exhibit black masses of hardened exudate along their stems (Woodruff 1966).
Hardened black masses of plant exudate indicate larval feeding within the stems.

One of my greatest pleasures with collecting insects is not only the sights of the habitats that I visit, but the sounds. How many a night I’ve spent camped out in the Ozarks and watched royal moths fluttering at the blacklight sheet while dueling katydids traded their raspy “ch ch ch“s in the tree branches above and a whip-poor-will sang it’s haunting, eponymous song off in the distance. What joy to be hiking the canyon-lands out west and hear the musical, descending “t-te-tee-teee-teew-teeew-teeeew-teeeeew” of the canyon wren echoing off the tall, sheer rock faces. Even large-treed urban parks offer the hypnotizing “wee-er, wee-er, wee-er, weeeeeeeee” of scissor grinder cicadas (Tibicen pruinosa) on a hot summer night. Ah—cicadas! Few other animals can match their ability to fill a landscape with song, and with more than 100 species in North America it’s a safe bet that no matter where you go you can hear cicadas.
Cacama valvata (Uhler, 1888) | New Mexico, Harding Co., 5 mi W of Mills
Scissor grinders were the cicadas of my urban youth in Kansas City; I was a teenager the first time I heard the rich, pulsing buzz of bush cicadas (Tibicen dorsata) in the prairies around my house farther east in Blue Springs; and I experienced my first periodical cicada (Magicicada spp.) event as a young adult in St. Louis with Brood XIX and their whirring, “flying saucer” chorus. More recently, I’ve made several trips to the western Great Plains, where particularly large cicadas known as “cactus dodgers” (Cacama valvata) perch on prickly pear (Opuntia spp.) and cholla (Cylindropuntia imbricata) cacti and sing their loud, distinctive songs in the scorching, mid-summer heat. The male song has been described as a high pitched “metallic zing” (Beamer & Beamer 1930) or as an intense shrill, often in short bursts (Kondratieff et al. 2002); however, to me it sounds like a dull-bladed table saw cutting through a piece of ironwood and hitting a nail!
Cholla (Cylindropuntia imbricata, Otero Co., Colorado) is a preferred host for Cacama valvata.
Fast flying and alert, cactus dodgers often defy the attempts of collectors (Kondratieff et al. 2002) and have the amazing ability to usually land safely on their spined hosts without becoming impaled (although occasionally this does happen—see photo below). The perils of dodging cactus spines, however, seem to pale compared with the benefits of utilizing these widespread hosts, as the association appears to have facilitated the spread of the species into a wide variety of environments across the southern Great Plains and westward to California (Sanborn & Phillips 2013).
This female has a cactus spine impaled on her head.
The photos in this post were taken during late June 2014 in the scorching, cholla-studded, shortgrass prairies of southeastern Colorado and northeastern New Mexico. Given their alertness and fast flying capabilities, they were a challenge to photograph before eventually finding the somewhat more cooperative subjects shown in the above photographs. Eventually, I was lucky enough to encounter two individuals sitting on a dead cholla stem in the mid-afternoon heat near Vogel Canyon, Colorado, one of which (the lower) was singing (and thus a male) and the other I surmised to be a female (this I confirmed once I got a better look through my camera viewfinder).
A male Cacama valvata (bottom) sings to a female (top).
The male was creeping slowly towards the female as it sang, pausing occasionally and interrupting his song before resuming both. I presumed I was witnessing courtship singing, a behavior Kondratieff et al. (2002) have described in detail. They observed males perched on the ends of branches producing long, wavering, repeated shrills as they moved closer to the female. The song changed to a long shrill followed by shorter sequence of shrills as they made their final approach, which was followed by touching with the legs, mounting, and copulation.
Cacama valvata male singing.
Unfortunately for this male, the female was already in the act of oviposition (poor male—wasting his time flirting with a married woman!). In cactus, females oviposit almost exclusively in dry, dead, skeletonized stems and rarely utilize green material (Beamer & Beamer 1930). The eggs laid by this female might remain in the dry stem for another three months or more, where they will await a fall rainstorm to wet the stem and ground and bring cooler temperatures to improve their chances of survival before hatching, dropping to the ground, burrowing into the soil, and searching for roots upon which they can feed.

During the past year or so I’ve followed up my longer (one week or more) insect collecting trips with a synoptic “iReport”—so named because they are illustrated exclusively with iPhone photographs. It may come as a surprise to some, but iPhones actually take pretty good pictures (especially if you pay attention to their strengths and weaknesses), and their small, compact size makes it easy to take lots of photos while trying to use time in the field wisely. I find the iPhone to be a great tool for documenting the general flavor of a trip and for taking quick photos of subjects before getting out the big rig. I will, of course, feature photographs taken with the ‘real’ camera in future posts.
For this trip, I teamed up with Jeff Huether for the third time since 2012. Our quarry for this trip was longhorned beetles (family Cerambycidae) in the genus Prionus. Larvae of these beetles are subterranean, with some species feeding on roots of woody plants and others on roots of grasses and other herbaceous plants. Among the latter are an array of species occurring in the Great Plains, many of which have been very uncommonly collected. However, in recent years lures have been produced that are impregnated with prionic acid—the principal component of sex pheromones emitted by females in the genus. Originally produced for use in commercial orchards (which are sometimes attacked by P. laticollis in the east and P. californicus in the west), these lures are proving themselves to be useful for us taxonomist-types who wish to augment the limited amount of available material of other, non-economic species in the genus. While Prionus was our main goal, rest assured that I did not pass on the opportunity to find and photograph other beetles of interest.
I began the trip by driving from St. Louis to Wichita, Kansas to meet up with Jeff, who had flown there from his home in upstate New York. Our plan was to visit sites in southeastern Colorado and northeastern New Mexico, where several of the Prionus spp. that we were looking for were known to occur. Before doing this, however, we stopped in Hardtner, Kansas to see “Beetle Bill” Smith and tour his amazing natural history tribute, Bill and Janet’s Nature Museum.
“Beetle Bill” Smith, founder of Bill & Janet’s Nature Museum, Hardtner, Kansas.
After the tour (and a delicious lunch at his house of fried crappie prepared by his wife Janet), we headed west of town and then south just across the state line into Oklahoma to a spot where Bill had found a blister beetle (family Meloidae) that Jeff was interested in finding. During lunch I mentioned a jewel beetle (family Buprestidae) that I had looked for in the area several times, but which had so far eluded me—Buprestis confluenta. Emerald green with a dense splattering of bright yellow flecks on the elytra, it is one of North America’s most striking jewel beetles and is known to breed in the trunks of dead cottonwoods (Populus deltoides). Bill mentioned that he had collected this species at the very spot where we were going, and when we arrived I was enticed by the sight of a cottonwood grove containing several large, dead standing trunks—perfect for B. confluenta.
Buprestis spp. love large, dead, barkless cottonwood trunks.
I searched for more than one hour without seeing the species, though I did find a few individuals of the related (and equally striking) B. rufipes on the trunks of the large, dead trees. Once that amount of time passes I’m no longer really expecting to see what I’m looking for, but suddenly there it was in all of its unmistakable glory! It would be the only individual seen despite another hour of searching, but it still felt good for the first beetle of the trip to be one I’d been looking for more than 30 years!

I usually wait until near the end of a collecting trip to take the requisite selfie, but on this trip I was sporting new headgear and anxious to document its maiden voyage. My previous headgear of choice, a vintage Mambosok (impossible to get now), finally disintegrated after 20 years of field use, and on the way out-of-town I picked up a genuine Buff® do-rag. I know many collectors prefer a brim, but I don’t like they way brims limit my field of vision or get in the way when I’m using a camera. Besides, I’m usually looking down on the ground or on vegetation, so sun on my face is not a big issue. And do I be stylin’ or wut?
A “selfie” makes the trip official.
We made it to our first locality in southeast Colorado by noon the next day—the vast, dry grasslands north of Las Animas. Jeff had collected a blister beetle of interest here on an earlier trip, but as I looked out across the desolate landscape I wondered what on Earth I could find here that would be even remotely interesting to me.
Shortgrass prairie habitat for Prionus integer.
Letting Jeff have some time to look for his blister beetle, I started down the roadside and after a short time found a live female Prionus sp. (later determined to represent P. integer). The only female Prionus I had ever collected before was P. heroicus, a giant species out in Arizona, and that was almost 30 years ago, so I wasn’t immediately sure what it was. Eventually I decided it must be Prionus, and a quick stop to kick the dirt while Jeff looked for his beetle turned into an intense search for more Prionus that surely were there. I did find two male carcasses shortly thereafter, and then nothing more was seen for the next hour or so.

During the time that I was searching, however, I started noticing strange burrows in the ground. I excavated a few—they were shallow but contained nothing. Nevertheless, they matched the size of the beetles perfectly—surely there was a connection?

I wondered if Jeff knew about the beetles occurring here, but when I showed him what I had found the surprised look on his face told me this was not the case. I showed him the burrows, and we both agreed they had to be connected. I got the shovel out of the truck and walked back to the area where I had seen the live female, then sunk the shovel deep into the ground next to one of the burrows and pried up a chuck of the soil containing the burrow in its entirety. As we broke apart the soil another female was revealed, and we immediately decided to set out some traps baited with prionic acid lures. We expected the beetles to become active during dusk, so we went into town to get something to eat and then check out another nearby locality before returning to the site at dusk. While we were gone it rained heavily at the site, so we weren’t sure if or how this would affect beetle activity and their possible attraction to the traps. However, as we approached the site (slipping and sliding on the muddy 2-track), we could actually see beetles crawling on the road from afar. What we found when we got out of the car was nothing short of mind-blowing—the beetles were everywhere, crawling on the road, crawling through the grass, and overflowing in the flooded traps! The vast majority were males, as expected, but we also found a fair number of the much more rarely collected females. This was significant, as the chance to observe mating and oviposition behavior made the encounter far more informative than if we had only found and collected the much more numerous males.

The following day we headed south into northeastern New Mexico to look at some shortgrass prairie sites near Gladstone (Union Co.) where two species of Prionus had been collected in recent years: P. fissicornis (the lone member of the subgenus Antennalia) and P. emarginatus (one of eight species in the poorly known subgenus Homaesthesis, found primarily in the Great Plains and Rocky Mountains). Fresh off of our experience the previous day, we were on the lookout for any suspicious looking “burrows” as we checked the roadsides at several spots in the area but found nothing, and while a few blister beetles piqued the interest of Jeff at one site, the complete absence of woody vegetation or flowering plants in general in the stark grassland landscape made the chances of me finding any other woodboring beetles remote. Eventually I became distracted by the lizards that darted through the vegetation around us, including this lesser earless lizard (Holbrookia maculata) and a collared lizard (better photos of both forthcoming).

Despite no clues to suggest that Prionus beetles were active in the area, we set out some traps at two sites with soil exposures that seemed similar to those seen the day before. As Jeff set the last pair of traps in place, my distraction with saurian subjects continued with a dusty hognose snake (Heterodon nasicus gloydi). While photographing the animal I looked down to my side, and what did I see but a male Prionus fissicornis crawling through the vegetation! I called out to Jeff, and for the next half an hour or so we scoured the surrounding area in a failed attempt to find more. We would not be back until the next morning to check the traps, so our curiosity about how abundant the beetles might be would have to wait another 18 hours. We cast an eye towards the north and watched late afternoon thunderstorms roll across the expansive landscape and decided to check out the habitat in nearby Mills Rim.
Thunderstorms over shortgrass prairie.
The rocky terrain with oak/pine/juniper woodlands at Mills Rim was a dramatic contrast to the gently rolling grasslands of the surrounding areas. We came here mostly out of curiosity, without any specific goal, but almost immediately after getting out of the car a huge Prionus male flew up to us—almost surely attracted by the scent of the lures we were carrying. Within a few minutes another male flew in, and then another. Because of their huge size and occurrence within oak woodland habitat, we concluded they must represent P. heroicus, more commonly encountered in the “Sky Islands” of southeastern Arizona. We stuck around to collect a few more, but as dusk approached we returned to the surrounding grasslands to set out some lures to see if we could attract other Prionus species. The frontal system that had waved across the landscape during the afternoon had left in its wake textured layers of clouds, producing spectacular colors as the sun sank inexorably below the horizon.
Sunset over shortgrass prairie.
This attempt to collect grassland Prionus beetles would not be successful, and as dusk progressed we became distracted collecting cactus beetles (Moneilema sp., family Cerambycidae) from prickly pear cactus plants (Opuntia sp.) before darkness ended our day’s efforts. This did not mean, however, that all of our efforts were done—there are still night active insects, and in the Great Plains what better nocturnal insect to look for than North America’s largest tiger beetle, the Great Plains giant tiger beetle (Amblycheila cylindriformis, family Cicindelidae—or subfamily Cicindelinae—or supertribe Cicindelitae, depending on who you talk to)?! We kept our eyes on the headlamp illuminated 2-track as we drove back to the highway and then turned down another road that led into promising looking habitat. Within a half-mile of the highway we saw one, so I got out to pick it up and then started walking. I walked another half-mile or so on the road but didn’t see anything except a few Eleodes darkling beetles (family Tenebrionidae), then turned around and walked the habitat alongside the road on the way back. As I walked, tiny little rodents—looking like a cross between a mouse and a vole—flashed in and out of my headlight beam as they hopped and scurried through the vegetation in front of me. Most fled frantically in response to my attempted approach, but one, for some reason, froze long enough under my lamp to allow me this one photo. When I posted the photo on my Facebook page, opinions on its identity ranged from kangaroo rat (Dipodomys sp.) silky pocket mouse (Perognathus flavus) to jumping mouse (Zapus sp.). Beats me.

Almost as if by command, it rained during the early evening hours where we had set the traps, and the following morning we were rewarded with traps brimming with Prionus fissicornis males. Not only were the traps full, but males were still running around in the vicinity, and we even found a few females, one of which was in the act of ovipositing into the soil at the base of a plant.

Eventually P. fissicornis activity subsided, and we decided to go back to the area around Mills Rim to see what beetles we might find in the woodland habitats. We also still were not sure about the Prionus beetles we had collected there the previous day and whether they truly represented P. heroicus. The scrubby oaks and conifers screamed “Beat me!”, and doing so proved extraordinarily productive, with at least a half-dozen species of jewel beetles collected—including a nice series of a rather large Chrysobothris sp. from the oaks that I do not recognize and a single specimen of the uncommonly collected Phaenops piniedulis off of the pines.

Not only is the scenery at Mills Rim Campground beyond spectacular, it also boasts some of the most adoringly cute reptiles known to man—such as this delightfully spiky horned lizard (I prefer the more colloquial name “horny toad”!). I’m probably going to regret not having photographed this fine specimen with the big camera.

Fresh diggings beside a rock always invite a peek inside. You never know who might be peeking out.
The trip having reached the halfway point, we debated whether to continue further south to the sand dunes of southern New Mexico (with its consequential solid two-day drive back to Wichita) or turn back north and have the ability to collect our way back. We chose the latter, primarily because we had not yet had a chance to explore the area around Vogel Canyon south of Las Animas, Colorado. We had actually planned to visit this area on the day we encountered P. integer in the shortgrass prairie north of town, and a quick visit before going back to check the traps that evening showed that the area had apparently experienced good rains as shown by the cholla cactus (Cylindropuntia imbricata) in full bloom.
Cylindropuntia imbricata | Otero Co., Colorado.
Whenever I see cholla plants I can’t help myself—I have to look for cactus beetles (Moneilema spp.). It had rained even more since our previous visit a few days ago, and accordingly insects were much more abundant. Several Moneilema adults were seen on the cholla, one of which I spent a good bit of time photographing. The iPhone photo below is just a preview of the photos I got with the big camera (which also included some very impressive-sized cicadas—both singing males and ovipositing females). The cactus spines impaled in the camera’s flash control unit serve as a fitting testament to the hazards of photographing cactus insects!

Later in the afternoon we hiked down into the canyon itself, and while insects were active we didn’t find much out of the ordinary. We did observe some petroglyphs on the sandstone walls of the canyon dating from the 1200s to the 1700s—all, sadly, defaced by vandals. Despite the rather uninspiring collecting, we stayed in the area for two reasons: 1) Jeff wanted to setup blacklights at the canyon head in hopes of collecting a blister beetle that had been caught there on an earlier trip, and 2) I had noted numerous Amblycheila larval burrows in the area (and even fished out a very large larva from one of them) and wanted to search the area at night to see if I could find adults. Jeff was not successful in his goal, and for a time I thought I would also not succeed in mine until we closed up shop and started driving the road out of the canyon. By then it was after 11 p.m. and we managed to find about a half-dozen A. cylindriformis adults. This was now the third time that I’ve found adults of this species, and interestingly all three times I’ve not seen any beetles despite intense searching until after 11 p.m and up until around midnight.

The next morning we found ourselves with two days left in the trip but several hundred miles west of Wichita, where I needed to drop Jeff off for his flight back home before I continued on home to St. Louis. I had hoped we could make it to the Glass Mountains just east of the Oklahoma panhandle to see what Prionus species might be living in the shortgrass prairies there (and also to show Jeff this remarkable place where I’ve found severalnewstaterecords over the past few years). As we headed in that direction, I realized our path would take us near Black Mesa at the western tip of the Oklahoma pandhandle, and having been skunked on my first visit to the area last year due to dry conditions but nevertheless intrigued by its very un-Oklahoma terrain and habitat I suggested we stop by the area and have a look around before continuing on to the Glass Mountains. We arrived in the area mid-afternoon and headed straight for a rock outcropping colonized by scrub oak (Quercus sp.) and pinyon pine (Pinus sp.)—very unusual for western Oklahoma—that I had found during my previous trip.
The area around Black Mesa couldn’t be more unlike the perception that most people have of Oklahoma.
I wanted to beat the oaks for buprestids—surely there would be a state record or two just sitting there waiting for me to find them, but as I started walking from the car towards the oaks the approach of a loud buzz caught my attention. I turned around to see—would you believe—a large Prionus beetle circling the air around me and was fortunate to net it despite its fast and agile flight. I hurried back to the car to show Jeff what I had found; we looked at each other and said, “Let’s collect here for a while.” The beetle had apparently been attracted to the lures in the car, so we got them out, set them up with some traps, and went about beating the oaks and watching for beetles to fly to the lure. Sadly, no jewel beetles were collected on the oaks, although I did find evidence of their larval workings in some dead branches (which were promptly collected for rearing). Every once in a while, however, a Prionus beetle would fly in, apparently attracted to the lure but, curiously, never flying directly to it and falling into the trap. Many times they would land nearby and crawl through the vegetation as if searching but never actually find the trap. However, just as often they would approach the trap in flight and not land, but rather continue circling around in the air for a short time and before suddenly turning and flying away (forcing me to watch forlornly as they disappeared in the distance). Based on their very large size, blackish coloration and broad pronotum, we surmised (and later confirmed) these must also be P. heroicus, despite thinking (and later confirming) that the species was not known as far east as Oklahoma. Not only had we found a new state record, but we had also recorded a significant eastern range extension for the species. And to think that we only came to Black Mesa because I wanted to beat the oaks!

We each collected a nice series of the beetles, and despite never witnessing the beetles actually going to the traps a few more were found in the traps the next morning after spending the night in a local bed & breakfast. I also found a dove’s nest with two eggs hidden in the vegetation, and as we were arranging for our room at the bed & breakfast a fellow drove up and dropped off a freshly quarried dinosaur footprint (the sandstone, mudstone, and shale deposits around Black Mesa are the same dinosaur fossil bearing deposits made more famous at places like Utah’s Dinosaur National Monument).

By the way, if you ever visit the area, the Hitching Post at Black Mesa is a great place to stay. A longhorn skull on the barn above an authentic 1882 stagecoach give a hint at the ambiance, and breakfast was almost as good as what my wife Lynne can do (almost! 🙂 ).

After breakfast we contemplated the long drive that lay between us and our arrival in Wichita that evening—our longer than expected stay in the area had virtually eliminated the possibility to collect in the Glass Mountains. Nevertheless, there was one more thing that I wanted to see before we left—the dinosaur footprints laying in a trackway along Carrizo Creek north of the mesa. I only knew they were in the area based on a note on a map, but as there were no signs our attempt to find them the previous day was not successful. Armed with detailed directions from the B&B owners, however, we decided to give it one more shot. Again, even after we found the site I didn’t see them immediately, I suppose because I was expecting to see distinct depressions in dry, solid rock. Only after the reflections of light from an alternating series of small puddles—each measuring a good 10–12″ in diameter—did I realize we had found them. Recent rains had left the normally dry creek bed filled with mud, with the footprints themselves still filled with water.

It is not surprising that I would be so excited to find the tracks, but what did surprise me was the effect they had on me. Seeing the actual signs of near mythical beasts that lived an incomprehensible 100 million years ago invites contemplation and reminds us that our time here on Earth has, indeed, been short!

By this time, we had no choice but to succumb to the long drive ahead. We did manage to carve out a short stop at the very first locality of the trip in an effort to find more Buprestis confluens (finding only a few more B. rufipes), but otherwise the day was spent adhering to our goal of reaching Wichita before nightfall. Jeff was home and sipping tea before lunchtime the next day, while I endured one more solid day of driving before making it back to St. Louis in time for dinner with the family. At that point, the trip already could have been considered a success, but how successful it ultimately ends up being depends on what beetles emerge during the next season or two from these batches of infested wood that I collected at the various spots we visited.

This past June I went out to one of my favorite spots in northwestern Oklahoma—Alabaster Caverns State Park in Woodward Co. The park, of course, is best known for its alabaster gypsum cavern—one of the largest such in the world—and the large population of bats that occupies it. Truth be told, in my several visits to the park during the past few years I have never been inside the cavern. The draw for me is—no surprise—it’s beetles. On my first visit in 2009 I found what is now known to be one of the largest extant populations of the rare Cylindera celeripes (swift tiger beetle), previously considered by some to be a potential candidate for listing on the federal endangered species list, and last year I found the northernmost locality of the interesting, fall-active jewel beetle Acmaeodera macra. This most recent visit was the earliest in the season yet, and as I walked the trails atop the mesa overlying the cavern I noticed numerous clumps of prickly pear cactus (Opuntia phaecantha) dotting the landscape.
Opuntia phaecantha | Alabaster Caverns State Park, Woodward Co., Oklahoma
Whenever I see prickly pear cactus anywhere west of Missouri I immediately think of cactus beetles—longhorned beetles in the genus Moneilema. A half-dozen species of these relatively large, bulky, clumsy, flightless, jet-black beetles live in the U.S., with another dozen or so extending the genus down into Mexico and Baja California, and all are associated exclusively with cactus, primarily species of the genus Opuntia. It wasn’t long before I found one, and deliberate searching among the cactus clumps produced a nice series of beetles representing what I later determined as M. armatum. The resemblance between Moneilema spp. and darkling beetles of the genus Eleodes is remarkable, not only in their appearance but also in their shared defensive habit of raising the abdomen when disturbed. The genus has been related taxonomically to the Old World genus Dorcadion, but Linsley & Chemsak (1984) regard the loss of wings and other morphological modifications to represent convergence resulting from the environmental constraints imposed by root-feeding, subterranean habits in arid environments and other situations where flightlessness is advantageous.

I have encountered Moneilema beetles a number of times out west, including this species in Texas where it is most common, but since I have only been photographing insects for the past few years this was my first chance to capture cactus beetle images as well as specimens. The above shot, taken with my iPhone, was straightforward enough, but I wanted some real photographs of the beetle—i.e., true close-up photos taken with a dedicated macro lens. I quickly learned that this would be highly problematic—those cactus spines are long and stiff and vicious, and these beetles are no dummies! Clearly their ability to adapt to such a terrifyingly well-defended plant has had a lot to do with the evolution of their slow, clumsy, flightless, you-don’t-scare-me demeanor. Normally when I photograph insects I do a little pruning or rearranging of nearby vegetation to get a clear, unobstructed view of the subject, and sometimes this also involves “pushing” my way into the vegetation to get the most desirable angle on the subject for the sake of composition. Not so here! In my first attempt, all I could think to do was locate a beetle sitting in repose and try to position myself in some way so that the beetle was within the viewfinder and the cactus’ spines were not impaled within my arms! The photo below shows the only shot out of several that I even considered halfway acceptable, but clearly the spines obstructing the view of the beetle were not going to be to my liking.
First attempt – looking down into plant where beetle was first sitting.
What to do? The beetle was behaving fairly well (i.e., it was not bolting for cover upon my approach), so I pulled out a pair of long forceps (that I carry with me for just such cases) and used them to gently prod the beetle into a more exposed position. The beetle crawled up onto one of the unopened cactus flower buds and perched momentarily, and I thought I had my winner photograph. I crouched down again, was able to get a little bit closer to the beetle than before, and fired a few shots. Looking at them in the preview window, however, left me still dissatisfied—the beetle was no longer obstructed, but the background was still jumbled, messy and dark, making it difficult for the dark-colored beetle to stand out. I would need to think of something else.
Second attempt – looking down on beetle after coaxing it up.
I actually take a lot of my photos with the insects sitting on plant parts that have been detached from the plant. This allows me to hold the plant in front of whatever background I choose and micro-adjust the position of the insect in the viewfinder for the best composition. This is “easier” (a relative term) with a shorter lens (think MP-E 65-mm) because the lens-to-subject distance matches almost perfectly the distance between my wrist and my fingers, allowing me to rest the camera lens on my wrist while holding the plant part with my fingers to “fix” the lens-to-subject distance. These beetles, however, are much too big for the MP-E 65-mm, so I had to use my longer 100-mm macro lens. The longer lens-to-subject distance does not allow resting the lens on my wrist, so I must come up with other ways of bracing myself and the subject to minimize movement. Detaching the pad on which the beetle was resting (and if you’ve never tried to detach an Opuntia cactus pad from its parent plant while trying not to disturb a beetle sitting on it, I can tell you it is not an easy thing), I also discovered that the pad was quite heavy and that holding it with the same forceps that I had used to prod the beetle (because of its vicious spines) was yet another unanticipated difficulty. I decided the best way to deal with it would be to get down on one knee in front of the plant, rest my arm on my other knee with the cactus pad extending out in front of me, and photograph the beetle with the plant as close in the background as possible to achieve a lighted and colored background that would help the beetle stand out. Following are examples of those attempts.
Third attempt – holding detaching pad with forceps for better view.
Detached allows even better close-ups.
Better for sure, especially the latter, closer one. Still, I wasn’t satisfied—the backgrounds still just had too much clutter that detracted from the beetle and complicated the lighting. I decided to go for broke—why not go for the blue sky background, the cleanest, most natural and aesthetically pleasing background possible! This actually was my first thought when I saw the beetles, but I could never find one on a high enough plant that was growing in a situation where I was able to crouch low enough to get the angle with the sky in the background. By this time my arm was quite weak from holding the heavy cactus pad and squeezing the forceps firmly, and as I contemplated how I could possibly hold the pad up towards the sky and take the shots without being able to rest the camera on my arm I had an idea. Why not rest my arm on the camera? Specifically on top of the flash master unit atop the camera. I adjusted the camera settings for blue sky background, positioned the cactus pad in the forceps so that the pad (and beetle) were hanging down from the forceps but still in an upright position, pointed the camera to the brightest part of the sky (a few degrees from the sun), and then held the cactus pad out in front of the camera with my arm resting on the flash master unit. It worked! My arm still got tired quickly and needed frequent breaks, and I had to do a number of takes to get the exposure settings and composition I was looking for, but the photo below represents my closest approach to what I envisioned when I first knelt down to photograph these beetles. A clear view of the beetle, on its host plant, with lots of nice value contrast between beetle, plant and background.
Fourth attempt – holding detached pad up against sky for cleaner background.
Once I had the technique figured out, I was able to get some really close-ups shots as well, still, however, with enough blue sky in the background to make it clean and pretty…
Zooming in with sky background gives a nice, clean close-up.
…as well as playing with some unusual compositions that one can afford to try only after they are confident they have gotten the required shots. I am particularly fond of the following photo, in which the beetle appears to be “peeking” from behind its well-defended hiding place on its host plant.
Having a little fun with the close-ups – he’s peaking!
If you have any experiences photographing these or other such “well-defended” insects (without resorting to the white box!) I would love to hear about them.

I’m back home after my week-long collecting trip to western Oklahoma, and at the risk of sounding hyperbolous I can only describe it as one of the most successful collecting trips I’ve ever had. Seriously! These kinds of trips don’t happen all that often for a variety of reasons—timing is off, rains didn’t happen, weather was uncooperative, etc. etc. Once in a while, though, everything comes together, and this was one of those times. The trip was also a return to my roots so to speak—I’ve been rather distracted in recent years with tiger beetles, but jewel beetles (family Buprestidae) and, to a lesser extent longhorned beetles (family Cerambycidae), are really the primary focus of my taxonomic studies. It had been several years since I’d had a good “jewel beetle trip,” so that was the focus of this trip. In planning the trip, I recalled seeing jewel beetle workings in several woody plant species in the same area during last September’s trip, and the occurrence of May rains seemed to bode well for my early June timing.
Gloss Mountains State Park, Major Co., Oklahoma
My instincts proved to be justified—in seven days in the field I collected an estimated 1000–1500 specimens representing at least two dozen species of Buprestidae and a dozen or more Cerambycidae. More important than the numbers, I collected a number of species in good series that I have either not or only rarely collected before, and in fact the second beetle that I collected turned out to be a new state record! Of course, I also brought along my full-sized camera and associated gear and photographed many of the species that I collected. I will feature these photos in future posts, but for this post I thought it might be fun to give a high level view of the trip illustrated only with photos taken with my iPhone (which I also carry religiously in the field with me). The iPhone is great for quick snaps of scenery and miscellaneous plants and animals for which I don’t feel like breaking out the big camera, or as a prelude to the big camera for something I’d like to share right away on Facebook. Moreover, there are some types of photos (landscapes and wide-angles) that iPhones actually do quite well (as long as there is sufficient light!).
Atop the main mesa at Gloss Mountains State Park, Major Co., Oklahoma
My first destination was Gloss Mountains State Park (Major Co.), a stunning system of gypsum-capped, red-clay mesas. I’ve already found a number of rare tiger beetles here such as Cylindera celeripes (Swift Tiger Beetle), Amblycheila cylindriformis (Great Plains Giant Tiger Beetle) and Dromochorus pruinina (Frosted Dromo Tiger Beetle), and in the past two falls I’ve found two interesting jewel beetle records: Chrysobothris octocola as a new state record, and Acmaeodera macra as a northern range extension. On this trip, I started out beating the mesquite (Prosopis glandulosa) and immediately got the longhorned beetle Plionoma suturalis—a new state record! They were super abundant on the mesquite, and I collected several dozen specimens along with numerous C. octocola as well. I then moved over to the red-cedar (Juniperus virginiana), which was showing a high incidence of branch dieback, and collected nice series of several buprestids, including what I believe to be Chrysobothis ignicollis and C. texanus. Up on top of the mesa there are small stands of hackberry (Celtis laevigata) and soapberry (Sapindus saponaria), both of which are very good hosts for Buprestidae. Not much was on the soapberry, but I beat large series of several Buprestidae from the hackberry, including what I believe to be Chrysobothris caddo and—the real prize—Paratyndaris prosopis! My old friend C. celeripes was also out in abundance, so I collected a series to add to my previous vouchers from this site. Back down below, I marveled at a juvenile western diamondback rattlesnake (Crotalus atrox) in the area where I found some more A. cylindriformis larval burrows. Daylight ran out before I could dig them up, and after 11 hours in the field I was exhausted, so I returned the next morning and got one 1st- and two 3rd-instar larvae and went back up on top of the mesa and beat several more P. prosopis from the hackberry.

My second stop was at Alabaster Cavern State Park (Woodward Co.), where C. celeripes was again abundant on the gypsum-clay exposures surrounding an impressive gorge thought to be a collapsed cave complex. I focused on beating hackberry because of the success with buprestids on this plant at Gloss Mountains SP, and although they were not quite as abundant here as at Gloss Mountains I still managed to end up with good series of C. caddo and several species of Agrilus. Because I had spent the morning at Gloss Mountains, I had only a partial day to explore Alabaster Caverns and, still getting used to the weight of the camera bag on my back, decided to leave the big camera in the car. This was a mistake, as I encountered my first ever bullsnake (Pituophis catenifer sayi) and had to settle for iPhone photos of this species—the photo above being the best of the bunch. An approaching storm put an end to my second day after another 10 hours in the field, and I drove an hour to Woodward.
Moneilema sp. on Opuntia phaecantha | Alabaster Cavern State Park, Woodward Co., Oklahoma
My third day started out at nearby Boiling Springs State Park, a riparian oasis on sandy alluvium alongside the nearby Cimarron River. The woodlands are dominated by hackberry and American elm, and although a few buprestids were beaten from hackberry and honey locust (Gleditisia triacanthos), the numbers and diversity were not enough to hold my interest in the spot. After lunch, I decided to return to Alabaster Caverns SP and explore some other areas I had not had a chance to explore during the previous partial day. It’s a good thing that I did, as I ended up finding a nice population of longhorned cactus beetles in the genus Moneilema associated with prickly pear cactus (Opuntia phaecantha). I collected a nice series of adults and also learned a few lessons in how to photograph these beetles on their viciously protective host plants. The photo above gives a taste of what will come in the photos that I took with the big camera. After eight hours in the field and darkness falling, I drove two hours to Forgan in Beaver Co.
Beaver Dunes State Park, Beaver Co., Oklahoma
Day 4 in the field started out cold and ominous, having stormed heavily during the previous night and with thick clouds still hanging in the sky. I feared the day might be a wash but decided to venture to Beaver Dunes State Park anyway and take my chances (beating can still be productive even in cold weather as long as the foliage is not wet). It’s a good thing that I did, as the buprestids were as numerous as I’ve ever seen them. The park’s central feature is a system of barren sand dunes that are frequented by ORV enthusiasts and surrounded by hackberry woodlands. The park also has a reservoir and campground, around which are growing a number of cottonwoods (Populus deltoides).

These hackberrys and cottonwoods proved to be extraordinarily productive. On the former I collected large series of several species of Chrysobothris and Agrilus, and while I collected fewer Buprestidae on the latter, these included Agrilus quadriguttatus and Poecilonota cyanipes! The latter species I had never collected until last year (from Cerceris fumipennis wasps), and beating the lower branches of the declining cottonwoods produced a series of about a dozen specimens. I also got one specimen on black willow (Salix nigra), along with a few Chrysobothris sp. and what I take to be Agrilus politus. Also in a low branch of one of the cottonwoods was a bird’s nest with a single egg that, according to Facebook comments, either represents the American Robin or a Gray Catbird. (I returned the next day and saw two eggs in the same nest.)

As the day drew to a close, I found two interesting longhorned beetle species at the edge of the dunes: one large, powdery gray Tetraopes sp. on milkweed (Asclepias sp.), and huge numbers of Batyle ignicollis evidently perched on the yellow spiked inflorescence of an as yet undetermined plant. I have seen this species on many occasions, but always in low numbers, yet here were literally hundreds of individuals on the plants, all having assumed a characteristic pose on the inflorescence suggesting that they had bedded down for the night. I only spent eight hours in the field on this day because of the late start, and as darkness approached I began the two-hour drive to Boise City.

The final two days in the field were supposed to be spent exploring the area around Black Mesa in the extreme northwest corner of Oklahoma, and another hour of driving was needed to get to the area from Boise City. I first went to Black Mesa State Park, and while the landscape was stunning (see above) the area was extremely dry. I feared the collecting would not be at all productive in this area but wanted to give the area a good effort before making a call. As I approached the entrance to the park, I saw a jeep parked by the side of the road with a license plate that read “Schinia,” which I recognized as a genus of noctuid moths that are very popular with collectors. I pulled over and talked to the driver, who was indeed a lepidopterist from Denver and had just arrived himself. We talked and exchanged contact information, and learning of my interest in beetles he directed me to a small stand of Gambel oak (Quercus gambelii) and one-seed juniper (Juniperus monosperma) on a sculpted sandstone escarpment not far from the park. I found the spot, and although I beat three Chrysobothris sp. from the first juniper tree that I whacked, another hour of beating produced only one more beetle from the juniper and nothing from the oak. I returned to the spot where we had met and encountered him again on his way out! We stopped and chatted again and found a few specimens of what I take to be Typocerus confluens on the yellow asters, but by then I was having my doubts about staying in the area. I told him I was going to check out a ravine in the park and then decide.

The petrified forest ended up being the only interesting thing I found in the ravine—the area was so dry that I think even the real trees were almost petrified! At any rate, it was clear that I was not going to have much success in this area. I looked at my watch, knowing that it would take three hours to drive back to Beaver Dunes, and estimated that if I left now I could get in about three hours of collecting at Beaver Dunes where I’d had so much success the previous day. Thus, I did what I rarely do on a collecting trip—drive during the afternoon!

I arrived back at Beaver Dunes with several hours of daylight still remaining, so I decided to take a look around the main dunes before heading towards the woody plants. I’ve actually visited Beaver Dunes previously, on the tail end of a fall tiger beetle trip in 2011. At that time I had seen only the rather common and widespread species Cicindela formosa (Big Sand Tiger Beetle) and C. scutellaris (Festive Tiger Beetle), but I thought there could still be a chance to see the much less common C. lengi (Blowout Tiger Beetle). Early June, however, is a little late to see the spring tigers, and in fact I saw only a single C. formosa. Nevertheless, I find dune habitats irresistible—alien habitats occupied by strange plants and animals, and I spent a bit of time exploring the main dune before heading back towards where I had collected so many Buprestidae the previous day.
Low water levels in the reservoir at Beaver Dunes are a result of three years of drought.
Western Oklahoma, like many parts of the central U.S., has suffered rather severe drought conditions for the past several years. This was evident not only in the large amount of branch dieback seen in the woody vegetation of the area (and probably a contributor to my success at collecting Buprestidae) but also the very low water level in the park reservoir. In the photo above the small cottonwood saplings in the foreground and large cottonwood trees in the left background indicate the normal water level. Cottonwoods, of course, like to keep their feet wet, and the trees around this reservoir—left high and dry by the drought—have responded with major branch dieback and lots of subsequent adventitious sprouting at the bases of the main branches. It was from this adventitious growth that I had beaten most of the Poecilonota cyanipes that I collected the previous day, so I repeated the cottonwood circuit in the hopes of collecting more. Not only did I collect more, but I collected twice as many as the previous day, so I ended up with a very nice series of more than two dozen individuals of the species from the two days collecting. I also did a little more beating of the hackberry trees which had produced well the previous day and collected several more Chrysobothris caddo, C. purpureovittata, and Agrilus spp. such as A. lecontei, A. paracelti, and perhaps others. When I arrived I was unsure whether I would stay here the following day, but eventually I decided I had sampled the area about as well as I could and that I would go back to the Gloss Mountains for my last day in Oklahoma. Thus, as the day began to wane I began hiking back to the car and spent the next two hours driving back to Woodward to spend the night.

Arriving at the Gloss Mountains the next morning was like coming home! I’ve spent so much time at this place and found so many great insects, yet every time I come here I find something new. Today, however, my goals were more modest—I wanted to improve on my series of Paratyndaris prosopis and Chrysobothris texanus, so I focused most of my time beating the hackberry and juniper on top of the mesa and continued beating the juniper down below as well. Success! I collected four more Paratyndaris off of the hackberry, but the C. texanus were far more abundant on this day than they were earlier in the week—I probably got another two dozen individuals of this species. Of course, I also got distracted taking photographs of a number of things, so the day went far more quickly than I realized. I wanted to leave around 6 pm and get in about three hours of driving so that I would have time to make it into Missouri the next morning and have a nice chunk of time to collect before finishing the drive and arriving home on Saturday night. It was actually closer to 7:30 pm before I hit the road, the reason for the delay being the subject of a future post (I will say that BioQuip’s extendable net handle comes in handy for much more than collecting tiger beetles!).
Long Creek | Hercules Glades Wilderness, Taney Co., Missouri
For my last day of collecting, I decided to stop by at one of my favorite spots in the White River Hills of extreme southwestern Missouri—Hercules Glades Wilderness in the Mark Twain National Forest. I’ve been to this place a number of times over the years, but in recent years my visits have usually been late in the season to look for the always thrilling to see Cicindelidia obsoleta vulturina (Prairie Tiger Beetle). It had actually been about 25 years since I’d visited these glades during the spring, and because of the success I’d had collecting in Oklahoma I was really optimistic that I would find the same here. Sadly (and inexplicably), insect activity was very low, and it didn’t take long for this to become apparent as branch after branch that I beat along the trail through the dry-mesic forest down to Long Creek yielded nothing. By the time I got to the creek I still had not collected a single beetle. A consolation prize was found along the creek, as beating the ninebark (Physocarpos opulifolius) produced a few specimens of the pretty little Dicerca pugionata, and a couple more consolation prizes were found further up the trail approaching the main glade when I saw a Cylindera unipunctata (One-spotted Tiger Beetle) run across the trail and then beat a single Agrilus fuscipennis from a small persimmon (Diospyros virginiana) tree at the edge of the glades. It had been about 25 years since I last collected the latter species, so I was very happy to see it, but no more were seen despite beating every persimmon tree that I saw during the rest of the day. At the end of the day, I had hiked seven miles and collected only six beetles—a rather inauspicious ending to what was otherwise a wonderfully successful trip.

Arriving back at the car at the end of the day on the last day of an extended collecting trip is always a little depressing—despite the vagaries of travel, cheap hotel beds, meals on the go, and general exhaustion, I’m never happier than I am when I am in the field. Still, the success that I’d had during this trip did much to ease my depression, and arriving home late that night and seeing my girls again (who waited up for me!) finished off any remaining depression.
