…and so it begins!

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.

Rich processes the day’s catch as the blacklight hums in the background.

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).

A cacophony of native wildflowers!

At first I thought this was a type of hover fly (family Syrphidae), but eventually I determined it to be Esenbeckia incisuralis, a horse fly (family Tabanidae)—incredible emerald green eyes!
Papilio polyxenes asterius (black swallowtail) caterpillar.
Echinocereus reichenbachii baileyi (lace hedgehog cactus).

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.

I believe this is Harrisina coracina, a leaf skeletonizer in the family Zygaenidae. Both BugGuide and the Moth Photographers Group show records only from Texas.

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.

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.

Cirsium undulatum (wavyleaf thistle or gray thistle) can be distinguished by its wavy leaves that are gray-green on both upper and lower surfaces.

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.

“62nd” Annual “Season-Opener-Birthday-Bug-Collecting-Trip”

This past Tuesday was my birthday, and as I have done for my entire adult life I took the day off and went on my traditional “Season-Opener-Bug-Collecting-Trip”. In the past I’ve usually just had one friend go with me, but today I had three—Rich, Chris, and Bill!

We started off by heading south about 3½ hours to Tingler Prairie Natural Area in Howell Co.. I wanted to come here because: 1) it was a place I’d never visited before, and 2) there is a population here of the endemic Ozark trillium (Trillium viridescens) that I thought might be in bloom. Rain in the forecast and a patch of the real thing on the way down had us a little worried, but the day turned out spectacular with temps climbing to 80°F and skies partly to mostly sunny.

We never did find the trillium—even calling another friend (Casey), who had seen them here before to find out exactly where he saw them. Turns out we hit the right spot, but apparently we were too early, especially given how late spring has been moving along this year. Nevertheless, we still found much to capture our interest, including a yellow-bellied racer (Coluber constrictor flaviventris)—too quick for photos—and a black rat snake (Pantherophis obsoletus) that coiled up nicely under the end of a fallen log and tolerated my prodding and “cleaning” of the scene around him to get some good photos (albeit, only with the iPhone).

The “cloudy” eye is actually an artifact of the flash lighting reflected by the retina.

Unfortunately, insect activity was very light. We saw no tiger beetles and only the earliest spring forms of most other insects. I took about 10 specimens each of the early-spring jewel beetles Acmaeodera tubulus and Pachyschelus purpureus, which I found on flowers and foliage (respectively) of wild geranium, Geranium maculatum. It was the first time that I’d found the latter as abundant as this, so the series of specimens will be a welcome addition to my cabinet. I also took a couple of A. tubulus on a flower of violet wood sorrel, Oxalis violacea and showed the others the characteristic end of an oak twig pruned by a twig pruner (Anelaphus parallelus) larvae (and revealed the culprit for them to see). Despite the paucity of insects, it was a beautiful and high-quality spot, and I look forward to collecting here again sometime when the season is more advanced.

After finishing up at Tingler Prairie, we drove east an hour and bushwhacked over rough Forest Service 2-track to Bald Hill Glade Natural Area in Ripley Co. It had been close to 10 years since my previous visit, but I remembered the roads well. We had to park, however, about a mile from the entrance to the glade due to fallen trees across the final stretch 2-track. The landscape had changed considerably since my last visit—gone was the dense, close forest lining the 2-track, and in its place stood open woodland brought to this condition by active management that included the use of prescribed burning apparently as recently as the past season.

Bald Knob Glade Natural Area.

After hoofing through the forest we reached the glade and found a beautiful—if somewhat sterile—scene before us. The recent burn included not only the woodland but also the glade itself, and no unburned refugia could be found anywhere. Floristically, this is beneficial for the glade, which needs periodic fire to prevent woody encroachment, but in my experience such burns also result in severely depressed insect populations for years afterwards. It takes time for the insects to find and recolonize the glade, and in this case the lack of unburned refugia will only increase the amount of time that will be needed for the insect populations to recover.

Nevertheless, we enjoyed our hike through the area, watched and listened to the calls and songs of a number of cool birds, including summer tanagers, indigo buntings, blue-gray gnatcatchers, and—a first for me—the splendidly yellow prairie warbler. We also took photographs of the glade and some of its plants (with the big camera), and on the way back to the car we found several of the Polistes wasp-mimicking light flies, Pyrgota undata (family Pyrgotidae). Interestingly, all were mating pairs, and the ones we observed closely (as we photographed them with the big camera) were engaged in a most curious “French kissing” behavior. I can’t wait to read up more on this when I prepare to post the photos of this behavior.

Eventually, impending dusk signaled a close to the day, and after driving east another 1½ hours to have pizza dinner in Poplar Bluff we made the long drive back to St. Louis (arriving at my home at 12:30 a.m.!).

2018 Arizona Insect Collecting Trip “iReport”

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 Oklahoma2013 Great Basin2014 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 yuccavoraAgrilus restrictus, Agr. arizonicusChrysobothris chiricauhuaMastogenius 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.

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.

Looking west from the Chiricahua Mountains, Arizona.

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!).

Rustler Park, Chiricahua Mountains, Arizona.

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 Polycesta aruensis.

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.

Trachyderes mandibularis female

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).

Not sure of the ID (other than ‘DYC’ – damned yellow composite).

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.

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…

Sarcostemma sp. (family Asclepiadaceae).

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.

Agrilus arizonicus mating pair – the males are brighter green than the females, which are more coppery.

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.

I was all lined up for a side shot of the bug when suddenly he took flight.

Actually they were all hanging out around a dead cat, some of which I scared up as they were feeding on it.

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).

Them’s some mandibles!

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!).

Meeting Pat Sullivan!

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 Mimosa dysocarpa – 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!

Stunning vista during the day! 

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.

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!

2018 New Mexico/Texas Insect Collecting Trip “iReport”

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 Oklahoma2013 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!

View from near the summit of Sandia Mountain.

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.

Bone dry Rio Grande!

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.

I believe this is a cactus dodger cicada (Cacama sp.).

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!

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 suturalis ssp. on an unidentified yellow comp.

What a sunset!

I’m happier than I look! 

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.

Incredible huge blue spider on the dune at night.

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!

The only thing cooler than this abandoned homestead was the squawking ravens hanging out on it!

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!

Some kind of wasp on some kind of flower.

There are four separate bird nests in the cholla plant – a veritable avian apartment!

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.

Updated field pic (the last one was taken in 1999!).

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.

The dunes are part of an extensive series of dunes stretching from West Texas through southeastern New Mexico.

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.

Burrows like this one look suspiciously like those of Prionus integer in Colorado – did another Prionus make this one?

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!

This roadrunner was rather annoyed with us for intruding in his spot of shade under a Siberian elm.

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!

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!

Promising clouds tease a thirsty landscape.

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.

Lots of virga, little rain.

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!

Variety of wasps on yucca.

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).

One of the more exciting finds of the trip – a jewel beetle in the genus Gyascutus on Juniperus monosperma (I believe this is G. carolinensis).
The greenish waxy bloom that covers the body must help the beetle blend into the foliage on which they perch.

A multi-tool comes in very handy for collecting cactus beetles!

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 Tragidion armatum adult feeding on a yucca flower and photographed a big-as-heck katydid.

Big katydid. You can tell this is a brachypterous adult because the anterior wings are on top and their costal margins oriented outside (in nymphs the posterior wings are on top and their costal margins oriented inside).

Perfect camouflage!

“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!).

2015 Texas Collecting Trip iReport—Fall Tiger Beetles

This is the fourth in a series of “Collecting Trip iReports”—so named because I’ve illustrated them exclusively with iPhone photographs. As I’ve mentioned in previous articles in this series (2013 Oklahoma2013 Great Basin, and 2014 Great Plains), I tend to favor my iPhone camera for general photography—i.e., habitats, landscapes, miscellaneous subjects, etc.—during collecting trips and save my full-sized dSLR camera only for those subjects that I want high-quality macro photographs of. iPhones are not only small, handy, and quick but also capable (within reason) of quite good photographs (see this post for tips on making the most of the iPhone camera’s capabilities). This keeps the amount of time that I need to spend taking photos at a minimum, thus allowing more time for the trip’s intended purpose—collecting! Those photos form the basis of this overall trip synopsis, while photos taken with the ‘real’ camera will be featured in future posts on individual subjects.

Last year during late September and early October I travelled to eastern and central Texas. This trip was all about fall tiger beetles, in particular certain subspecies of the Festive Tiger Beetle (Cicindela scutellaris) and Big Sand Tiger Beetle (Cicindela formosa) found in that area that I had not yet seen. I enjoy all collecting trips, but fall tiger beetle trips are among the most enjoyable of all—cooler temperature, a changing landscape, and charismatic subjects that are both fun and challenging to find and photograph. This trip was no different, with spectacular weather during the entire week and, for the most part, great success in finding the species/subspecies that I was after. At this point I’d like to acknowledge the help of several people—David Hermann (Ft. Worth, Texas), David Brzoska (Naples, Florida), and Steve Spomer (Lincoln, Nebraska), who generously provided information on species and localities. My success at finding these beetles was due in large part to the information they provided.


Day 1 – Cobb Hollow

My car

Little question about what I am doing out here.

After driving 700 miles from my home near St. Louis, I arrived at the first stop of trip—Cobb Hollow in north-central Texas. This small creek lined with deep, dry sand is close to Forestburg (Montegue County)—the type locality of Cicindela scutellaris flavoviridis, a beautiful, all-green subspecies with the elytra suffused golden-yellow.  The habitat looked very promising from the start, and it wasn’t long before I found the first tiger beetle of the trip—a gorgeous, red nominate Big Sand Tiger Beetle (Cicindela formosa formosa). Not long after that I found the first Cicindela scutellaris flavoviridis, and over the next few hours I would find a total of nine individuals. Despite the extensive habitat along the creek the beetles were quite localized, occurring primarily in two dry sand areas within a mile west of the bridge. This spot is actually near the northern limit of the subspecies’ distribution, and several of the individuals showed varying influence from nominate scutellaris with the elytra tending to be more red than yellow-green. There was a diversity of other tiger beetles here as well—C. formosa formosa was the only one that was common, but I did find also a few individuals each of Tetracha carolina, Cicindelidia punctulata, Cicindela splendida, and C. repanda. A very cool place.

Day 2 – Stalking the Limestone Tiger Beetle

Today was all about looking for the Limestone Tiger Beetle, Cicindelidia politula. I have collected this species previously at several sites in Erath and Somervell Counties, Texas (west of Ft. Worth) and featured photographs from that trip. However, since I would be passing through the area on my way south I decided to spend a day looking for it again and, hopefully, collecting a few more specimens. Cicindelidia politula is related to the much more common and widespread Punctured Tiger Beetle, C. punctulata, but is shiny blue-black with the elytral markings absent or limited to the apices and the abdomen red. I visited several localities—two new ones for me in Erath County and another I had visited previously in Somervell County, with habitats that ranged from rocky clay to white limestone exposures along roadsides and even limestone gravel.

I found a fair number of individuals at the first site (1.7 mi SW Bluff Dale, Jct US-377 & FM-1188), which had a finely ground limestone substrate. Most of the individuals were flushed from the base of clumps of bunch grass and captured when they landed in more exposed situations.

The beetle had also been reported along the roadsides at the second location (0.4 mi E Jct FM-2481 on CR-539), but the only individual I saw here was on a very coarse crushed limestone 2-track leading off of the main road.

The species was most numerous at the third site in Somervell County (3.4 mi SE Jct US-67 on CR-2013). I collected ten individuals and saw probably that many more on white limestone exposures along the roadside and along a dirt road cut along the base of the hill to the NE side of the highway. Most of the beetles in the latter area were seen along the scraped dirt road (at left in 2nd photo below), although presumably the beetles also utilized the undisturbed, surrounding habitat.

Catching the beetles at this last locality was challenging—the adults are fast and flighty, and the rough, rocky habitat made it difficult to clamp the net over the beetle and pounce on top of the rim before they were able to find a gap and escape. With practice I found my catch efficiency increased a little bit if I slowly approached the beetle and then made an assertive swing with the net right when the beetle began to fly—the trick is learning how to tell when they are ready to fly (and “assertive” is the key word!). Tiger Beetle Stalker; however, does not quit!

Day 3 (Part 1) – Pedernales Fall State Park

This was another locality where Cicindela scutellaris flavoviridis had been recorded. I came here to find this subspecies even though I had seen it two days previously at Cobb Hollow, because that latter population showed some slight intergradation of characters from nominate C. scutellaris and I wanted to get field photographs of a “pure” population. I was pretty excited when I saw extensive dry sand habitat lining the upper bank area along the Perdenales River; however, I found no tiger beetles of any kind after extensive searching through that habitat. I did note the area seemed dry and reasoned that perhaps timely rains had not yet triggered emergence of C. scutellaris, C. formosa, and other sand-loving fall tiger beetles. I did find a small area of wet sand right along the water’s edge where three species of Cicindelidia could be seen: C. ocellata rectilatera, C. trifasciata ascendens, and C. punctulata. I’ve photographed all of these species before, so I didn’t try to spend any time doing so here. However, combined with the species seen the previous two days, this made a total of ten species seen on the trip so far. Although I didn’t find the beetle I was looking for, I marveled at the beauty of the area, especially the Pedernales River with its hard, conglomerate bedrock and mini shut-ins and spent quite a bit of time here taking photographs.

Day 3 (Part 2) – Lick Creek Park

Another of the Festive Tiger Beetle subspecies that I wanted to look for was Cicindela scutellaris rugata. I had several localities from which this solid blue-green subspecies has been recorded, and this site was the nearest of those that I planned to visit. The drive from Pedernales State Park was longer than I anticipated, so I didn’t get to this spot until close to 6 p.m. At first I worried that I wouldn’t have enough time to even find suitable habitat, but that was no problem as I quickly found the Post Oak Trail and its perfect open, post oak woodland with deep sand substrate. By all accounts the beetles should have been all over the trail but they weren’t. As with the previous site, the area was quite dry as evidenced by the wilted plants along the trail side, and I also note that the previous record from here was on Oct. 23rd—more than three weeks later. Despite the fact that I didn’t find any tiger beetles, I did see a young timber rattle snake (Crotalus horridus) crossing the trail late in the hike—I took a quick shot with the iPhone (see below) and then broke out the big camera and was able fire off a few shots before it left the trail and headed for cover. (Several people walking the trail came upon us, and they were all—happily—more than willing to oblige my requests to stay away until I was finished.)

Day 4 – East Texas cemeteries

Cemeteries are often great places to look for tiger beetles because they tend to be located on parcels of land with low agricultural value that were donated by landowners to local churches. Older cemeteries especially tend not to be highly maintained and, thus, offer excellent habitat for tiger beetles. My goals for this day were Cicindela scutellaris rugata and the gorgeous Cicindela formosa pigmentosignata. I had records of both from a couple of cemeteries in eastern Texas (Sand Flat Pioneer Cemetery in Henderson and Morris Chapel Cemetery in Van Zandt Counties) and found good numbers of both along sandy 2-tracks and sparsely to moderately vegetated sand exposures in and around the cemetery grounds. I don’t have any iPhone photographs to share of either of these species, but I did spent a lot of time with the big camera and got a number of photos of each that I am quite pleased with—I’ll share those in future posts. The cemeteries themselves were haunting and poignant, with some headstones dating back to the late 1800s.

At Morris Chapel Cemetery I found C. formosa pigmentosignata and C. scutellaris rugata on sparsely vegetated deep dry sand 2-track north of the cemetery. I did also manage to get field photos of the former before it got too hot and they became too active. There were also a few of the latter in the open sandy ground just outside the northwestern edge of the cemetery. As with Sand Flat Pioneer Cemetery, I spent a bit of time in the cemetery proper to look at the headstones—the oldest headstone also being the most poignant; a one and a half-year old boy who died in 1881.

After finishing up at Morris Chapel Cemetery I returned to Sand Flat Cemetery to see if I could get more field photographs before the beetles bedded down for the night. The sun was still up when I arrived a little before 6 p.m., but the shadows were long and no beetles were seen. Not one to waste an opportunity, I broke out the big camera anyway and started photographing a large species of bee fly (family Bombyliidae) that was perching on the ground and on the tips of plains snakecotton (Froelichia floridana).

Day 5 (Part 1) – Cowtown Bowman Archery Club

With both specimens and good field photos of Cicindela scutellaris rugata and C. formosa pigmentosignata in hand, I returned my attention to C. scutellaris flavoviridis. Again, I did already have specimens in hand from Cobb Hollow, but most of them showed some degree of intergradation with nominate C. scutellaris and I was hoping to see some “pure” individuals. Failing to find it at the more southerly locations (Pedernales State Park and Lick Creek Park), I had one more location in Tarrant County where the subspecies had been recorded—a sand borrow pit near the entrance of Cowtown Bowman Archery Club. Once again I searched the area thoroughly for a couple of hours during mid-morning but did not see the subspecies or any other tiger beetles. Conditions were overcast and cool (72°F), but I do not think this explains the absence of adults. Rather, I think I was on the early side of the season and they just hadn’t started emerging at this site.

While I was at the site I found several tiger beetle larval burrows in a moderately vegetated area near the deeper sand deposits that were occupied by Tetracha carolina, so I used the “stab” or “ambush” method to collect several 3rd instars for an attempt at rearing. For those of you who are not familiar with this technique, a knife is set at a 45° angle with the tip in the soil about 1″ from the edge of the burrow. Then you wait, sometimes for quite a while, until the larva reappears at the top of the burrow and STAB the knife assertively into the soil to block the larva from retreating. The larvae are extremely wary with excellent vision and will usually drop back down immediately when they see you, so you have to be ready and act quickly. Once the retreat is blocked, a simple twist of the knife to expose the larva is all that is needed. I prepared larval habitats by placing native soil with as intact a top layer as possible in plastic critter carriers, made a starter hole for each larva with a pencil, dropped each larva into one of the holes, and then pushed the soil to seal the burrow entrance. This prevents the larvae from crawling right back out of the starter burrow, which can result in them encountering and fighting each other. The larvae will eventually reopen the burrow entrance, but after being sealed inside for a while they usually accept the burrow and further modify it to suit their needs.

Day 5 (Part 2) – Cobb Hollow (epilogue)

Although I had found Cicindela scutellaris flavoviridis at this site on the first day of the trip, I had not taken any field photographs in hopes of finding a more “pure” population at one of the more southerly locations. That did not happen, so I returned to Cobb Hollow on this last day in the field to get field photographs from the population there. Temperatures were a bit cooler (mid-70s) and cloud cover was variable, actually sprinkling when I arrived mid-afternoon but eventually clearing. This seemed to have no detrimental effect on adult presence, and it may have actually helped as I was able to photograph the very first individual that I found to my heart’s content. I collected that individual and the next three that I saw by hand and found two more over the next hour—all on the same deep, dry sand bars west of the bridge where I had seen them previously. Curiously, Cicindela formosa was strangely absent from these same areas where they had been so numerous a few days earlier.

On the east side of the bridge I collected two more Tetracha carolina in the same moderately vegetated sandy clay spot as last time, then went on to the furthest dry sand bar where I found and photographed (but did not collect) a single C. formosa (only one shot before it took off). I also found a female green lynx spider (Peucetia viridans) sitting on her egg mass and got some nice macro photos as well as this iPhone shot (talk about a face only a mother could love!).

Summer Insect Collecting iRecap

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


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

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

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

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

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

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

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

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

Sand plain deposited 2009

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

Sand plain deposited 2009

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

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

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

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

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

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

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

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

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

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

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


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

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

"Medora" Dunes

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

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

Asclepias tuberosus "yellow form"

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

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

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

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

Salt marsh

Quivira NWR – salt marsh habitat for halophilic tiger beetles

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

Salt marsh

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

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

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

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

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

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

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

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

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

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

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

Trap baited with prionic acid lure

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

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

Prionus debilis

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

Prionus debilis

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

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

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

Calling all insects—the blacklight awaits you!

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

More chillin’ after work
Pinewoods Lake, southeast Missouri (28 July 2015)

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Pinewoods Lake at dusk, again!

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

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

Blacklighting w/ beer

Blacklighting is better with beer!

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

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

Neoscona sp. courtship

Be very, very careful boy!

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

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

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

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

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

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

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

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

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

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

Spiney, scaley distractions

Those who have read this blog for any length of time know that single-mindedness is not one of my shortcomings. I call myself a coleopterist and even go on trips dedicated specifically towards their study, yet find it impossible to ignore the diversity of non-beetle insects that one finds on such trips. It doesn’t stop there—insect diversity is supported by plants, interesting in and of themselves but even more so in the ways they mix and match to form distinct natural communities. And, of course, natural communities are themselves a product of the landscape—soil and terrain, moisture and its timing, elevation and latitude and longitude. Field trips for me are a constant struggle between the inner specialist—wanting to know everything about my chosen niche (beetles)—and outer generalist—wanting to know something about everything else. But wait—that was a decidedly spineless perspective. There are also animals with spines out there. Not nearly as many as those without, mind you, but that just makes them special—more of a treat to be relished when seen, and among the spined it is the reptiles that get me most excited.

Holbrookia maculata (lesser earless lizard)

Holbrookia maculata (lesser earless lizard), female(?) | Union Co., New Mexico.

This post presents a trio of reptiles that distracted my attentions one day during last year’s Great Plains Collecting Trip. We were looking for promising habitat for Prionus longhorned beetles in northwestern New Mexico (Union Co.), where two species (P. fissicornis and P. emarginatus) had been collected recently in the area’s vast shortgrass prairie. Remembering our experience the previous day finding another species (P. integer) and its burrows, we were on the lookout for anything that looked remotely like a “burrow” but found nothing. The stark grassland landscape offered little woody vegetation that made the chances of finding any other woodboring beetles remote, and eventually I became distracted by lizards darting amongst the vegetation around us. The first was one I’d never seen before—the lesser earless lizard (Holbrookia maculata), rather small lizards that were extremely wary, difficult to approach, and quick to dash behind the nearest grass clump. I managed one fairly adequate iPhone photo, but I wanted better photos and had grown weary of finding no beetles so broke out the big camera.

I presume the first photo (two above) is a female while the second photo (immediately above) is a male based on the paler coloration and less distinct black markings of the former. The preferred habitat of “relatively level terrain with sparse, low-lying vegetative cover and loose, friable soils” (Degenhardt et al. 2005) describes perfectly the habitat in which we found them. They were extremely difficult to photograph due to their proclivity to hide behind vegetation, and the two photos shown here were about as far in the open as I could get them while trying to approach with the camera.

Crotaphytus collaris (common collared lizard)

Crotaphytus collaris (common collared lizard) | Union Co., New Mexico.

I have loved collared lizards ever since I first photographed a nice, big, colorful male Crotaphytus collaris (eastern collared lizard) in western Oklahoma back in 2009. When I saw this still striking but much less colorful individual, I didn’t know what species it was, but I didn’t think it was the eastern species that I had already encountered not only in Oklahoma but also several times on igneous glades in my home state of Missouri. To my surprise, however, the eastern species is the only one inhabiting New Mexico (Degenhardt et al. 2005)—other species distributed further to the west or south. I had better luck photographing this individual, for even though it occasionally ducked into the vegetation (allowing one charming shot of it peering above the “grass” line—see third photo below) it was also content to stay out in the open along the gently sloped road bank where I had found it and dart from spot to spot between suspicious glares. This particular individual was smaller than the big males I have seen, so I suspect it is either a female or a juvenile.

Crotaphytus collaris (common collared lizard)

Not shy about remaining fully exposed, it clambered atop a rack to watch more carefully.

Degenhardt et al. (2005) mention an interesting factoid about collared lizards regarding the fact that they, unlike many other lizards, do not readily lose their tails (autotomy). Collared lizards are fast runners, often rearing up on their two hing legs, for which an intact tail would be an important organ for maintaining balance. In the case of these lizards, the advantages of rapid locomotion probably outweigh benefits from tail autotomy.

Peering charmingly above the “grass” line.

While two reptile species at one stop might seem doubly lucky, little did I know a hat-trick still awaited me. We still had no solid evidence to suggest that Prionus beetles were active in the area, but we set out two traps anyway because the soil exposures seemed similar to those we saw the day before and then moved just down the road to where the soils turned redder and seemed to have higher sand content to set one more trap. As Jeff set the trap, my distraction with saurian subjects continued when I ran into a marvelously camouflaged western hognose snake (Heterodon nasicus).

Hognose snake

Heterodon nasicus (western hognose snake) | Union Co., New Mexico.

Western hognose snakes are typically found in grassland habitats with sandy soils (Degenhardt et al. 2005), so the occurrence of this individual at this spot was no surprise. What was a surprise was how strikingly marked this individual looked compared to the other two individuals I’d seen to this point—the first a more subtly marked individual in a rare sand prairie in southeastern Missouri, and the second a more uniformly mottled individual in northwestern Oklahoma’s Salt Plains National Wildlife Refuge. This could be a result of subspecific differences—Missouri populations are assigned to the subspecies H. nasicus gloydi (dusty hognose snake), but I am unsure of the subspecific assignment of the Oklahoma individual. According to Degenhardt et al. (2005) only the nominate subspecies occurs in northern New Mexico (subspecies H. n. kennerlyi can be found in the southwestern part of the state, while intergrades with subspecies H. n. gloydi are said to occur in the extreme southeastern part of the state).

Hognose snake

The strongly upturned rostral (snout) is one character distinguishing the western from the eastern hognose snake.

All species of hognose snakes are famous for their well-choreographed sequence of defensive displays. While they are said to rear up cobra-like and strike out with their mouth open while hissing, I have never seen this behavior by any of the western or eastern hognose snakes that I’ve encountered. The first western individual I saw (in Missouri) insisted on continually trying to burrow into the deep, loose sand and made no other defensive display, while the eastern individual referenced above simply tried to run, although it did eventually barf up a half-digested frog! The individual shown here seemed reticent to do much of anything, remaining coiled up and watching and coiling even tighter as my molestations continued. At last, this one performed some theatrics by writhing in mock agony and then rolling over on its back and playing dead (a behavior called thanatosis). The Oklahoma snake also did this, adding further dramatic value by opening its mouth wide, allowing the tongue to protrude, and ejecting blood from the lacrymal glands while emitting musk from the cloaca. This one didn’t do too much with its mouth, but it did so much more with its cloaca (defecating!). If the idea of eating a snake isn’t revolting enough to begin with, then surely eating a snake covered in crap is!

Hognose snake

The ultimate in thanatotic displays—not only dead, but covered in crap!

In addition to the strongly upturned rostral (snout), best seen in the second photo above (the rostral is only moderately upturned in the eastern species), the black-checkered ventral coloration seen in the third photo confirms this as the western hognose species. The eastern hognose snake is distributed further east and does not occur in New Mexico (Degenhardt et al. 2005).

In an amusing twist to the search for Prionus at this site, while photographing the animal I happened to look down to my side and saw a male Prionus beetle crawling through the vegetation! I recognized the species immediately as P. fissicornis—represented in my cabinet by only a single specimen, and although Jeff and I would find no more after a through search of the area, our traps yielded a “bucket loads” of the beetles the next morning.

A little extra cash

Earlier this month the Webster Groves Nature Study Society (WGNSS) sponsored their second Nature Photo Contest. I’ve been a member of this group since I first moved to St. Louis after college in the early 1980s—primarily as a participant in the Entomology Natural History Group but for the past six years also as board member and editor of the Society’s newsletter, Nature Notes. The photo contest was run much like the first one in 2013, again with nice cash prizes for the winners, except two things: 1) the categories were a little different (see below), and 2) I was tapped to be one of the three judges in the two categories that I did not submit photos. The categories were:

  • Invertebrates
  • Vertebrates
  • Plants & Fungi
  • Natural Communities
  • Seasons

I submitted two photos each to the first three categories—the maximum allowed in both cases. One limitation for me was that the photographs had to be taken in Missouri or an adjacent state. Remarkably, during the past few years I’ve taken most of my photos in places further afield—primarily in the western U.S. in states such as California, Colorado, New Mexico, and Nevada. I have many photographs from earlier years, but frankly I don’t consider much of that body of work to be photo contest worthy. Still, I was able to come up with a few more recent photographs that I thought would be competitive.

How did it go for me? Pretty good, with two of my photos taking cash-winning prizes (see below). This may not be as good as I did last time, when I won one 1st place, one 2nd place, and one 3rd place—the last of these also voted by the audience as the Grand Prize winner. Nevertheless, the cash award is much welcomed and will be put to good use. Remarkably, it turns out that two winning photographs have never been posted at this site, so here they are:


3rd Place—Vertebrates

The judges regarded that it represents the true “essence” of a snake. Technically they liked the position of and focus on the tongue, the contrasting red color working well in the composition, with the blurred, winding body of the snake adding depth in a cleaner fashion than a cluttered jumble of leaves. I can’t tell you how many shots I took hoping to get one with the tongue in the perfect position—knowing all along that at any moment the snake could stop flicking it or decide to make a run for it


2nd Place—Plants & Fungi

Dicentra cucullaria

Dutchman’s breeches, Dicentra cucullaria | Battle of Athens State Park, Clark Co., Missouri

Unfortunately, I didn’t get a chance to hear the judges’ feedback regarded this photo, as I was busy judging the photos in the ‘Natural Communities’ and ‘Seasons’ categories. This photo also took many shots, even though I didn’t have to worry about the subject not cooperating. Flash on white is tricky—not enough and you don’t get the stark contrast with the black background; too much and you end up blowing the highlights and losing the delicate detail. Add to that trying to get the subject perfectly symmetrical within the frame (I wanted to achieve this ‘for real’ and not through subsequent cropping), and I probably took close to two dozen shots before I felt like I had it right.

Perhaps you noticed that neither of the photos were in the ‘Invertebrates’ category. This just goes to show that the amount of interest in and effort one puts into a certain type of photography does not guarantee success—or prevent success in photographing other, less-familiar subjects. For my part I am pleased that any of my photographs were deemed good enough to receive a cash prize and thank WGNSS for giving local nature photographers the opportunity to have their work recognized and rewarded.
