Orchid Valley Natural Area

This month’s destination for the WGNSS Natural History Photography Group was Orchid Valley Natural Area in Hawn State Park. This natural area is south of the main park and not normally open to the public, but we were granted permission to enter by the park administration. Our targets were several species of orchids and other rare plants that are known to occur in the area—showy orchis (Galearis spectabilis) being the one I hoped most to see.

Our group for the day (front to back): me, Lynne, David, Casey, Avery, James, Bill, and Rich (Chris behind tree at back).

There are no trails here—not even a place to park, as we squeezed our cars against the side of the road at a spot that appeared to provide good access. A bit of GPS-guided bushwhacking brought us to increasingly rough and sloping ground that ended up at the edge of a cliff overlooking one of the sandstone box canyons that this area is know for—down below was where we wanted to go. Wild azaleas lined the upper canyon edges with their stunning pink blossoms. We followed the canyon edge and found a way down, then circled back into the canyon to find a stunning waterfall, its sandstone walls dripping with mosses and ferns. We spent quite a bit of time here photographing the waterfall and surrounding area before eventually resuming the search for the orchids that we came to see.

The waterfall fell about 25 feet onto the sandstone rocks below, its splash creating perfect conditions for luxurious growth of mosses and ferns.

Mosses sending up their “stems” (actually setae), each holding up a capsule filled with spores.

Sadly, the orchids were not yet in bloom—not even close, another victim of the cold, late spring we’ve been experiencing. Casey, our group leader, did find some very small showy orchis leaves, and we saw some nice clumps of another native orchid, rattlesnake plantain (Goodyera pubescens), an evergreen orchid that blooms during late summer. We hiked up another drainage that led to another box canyon—lacking a waterfall but equally impressive, nonetheless—but found no orchids in bloom there, either. We did, however, see cinnamon ferns sending up their spike-like fertile fronds and aggregations of antlion larvae (a.k.a. “doodlebugs”) in the soil beneath the sandstone ledges.

Pits of antlions, or “doodlebugs”, clustered in the soil beneath a sandstone ledge. Ants and other insects that fall into the pits are quickly dispatched by the sickle-shaped mandibles of the bug lying buried at the bottom of the pit.

You might think failure to find what we were looking for would result in a disappointing field trip—far from it! Time in the field with like-minded friends in a beautiful spot is always a pleasure, and when it comes to searching for rare plants (or insects, or whatever), failure is the norm—making success, when it does come, that much sweeter. There will be other chances to see showy orchis (perhaps in a couple of weeks).

“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.

Fire pink, Silene virginica (family Caryophyllaceae) thrives on a dry, cherty hillside.

Mayapple, Podophyllum peltatum (family Berberidaceae) prefers the rich, more mesic hillsides (this is where we expected Trillium viridescens to occur).

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.!).

When hardcore botany meets hardcore nature photography—nature geekery at its finest!

Last Saturday, the Webster Groves Nature Study Society (WGNSS) Nature Photography Group was joined by several members of the WGNSS Botany Group and Missouri Native Plant Society to look for one of Missouri’s rarest plants—Geocarpon minimum, a.k.a. tinytim or earth-fruit (family Caryophyllaceae). This diminutive, federally-threatened and state-endangered plant grows only on sandstone glades, primarily in west-central Missouri with a few populations known also from Arkansas, Louisiana, and Texas. The window for finding this plant is short—it’s entire life cycle lasts only about 4 weeks, with an even shorter window for finding it in flower.

Our first stop to look for them was Bona (pronounced “Bonnie”) Glade Natural Area. I’d been here before, but it was about 10 years ago and at the wrong time to look for this plant (but I did find widowscross, Sedum pulchellum, in bloom). Some of the group had seen it here before and were able to coach us on the microhabitat where we would likely find them, and it didn’t take long before we did. Soon after finding the first plants, we found them in bloom as well—their almost microscopic flowers being the perfect subject for my macro lenses!

Claytonia virginica (spring beauty) (family Montiaceae).

After getting plenty of shots of the plant and flowers, we moved to an adjacent plot of land across the highway, where we not only found more tinytim plants but also Corydalis aurea, commonly called golden corydalis (pronounced koor-ID-uh-lyss), in the family Papaveraceae—something I’d never seen before.

Next the group moved on to Corry Branch Glade. It was originally our intent to look for more of the plant at this site, but immediately upon entering the glade we noticed a stunning display of Selenia aurea, or golden selenia. This small, striking species in the mustard family is restricted to just a handful of counties in the west-central part of the state, again primarily glade habitats. It was a surprising and pleasant find that occupied the groups’ attentions for some time before we finally decided to break for lunch (it was well into the afternoon!). While I was there, I not only photographed the plant but started having some success with my new 15-mm wide-angle macro lens, with which I had been experimenting all day (to that point without much success).

After “lunch” (which was closer to dinner!), a few of us (Bill, David, and I) wanted to go back to Bona Glade to take another crack at photographing tinytim with our wide-angle macro lens. I especially was not satisfied with what I had gotten earlier, that being my first serious attempt at using the lens in the field. Having a better idea now of how to use the lens and what our compositional goals were, we scoured the area looking for just the right plants in just the right situations. I can honestly say I finally got a feel for how to use the lens, the trickiest part of it being how to balance use of flash on the subject with the amount of ambient light from the background (I’m not a stranger to this concept at all, frequently having combined flash with “blue sky” in much of the macrophotography I’ve done up to this point). We photographed several plants on different substrates looking for the right combination of plant, substrate, and background, and we all walked away pretty optimistic that we’d gotten the photos that we wanted.

My thanks to Casey and Ando Galvan for letting me ride down there with them, to David Seidensticker and Bill Duncan for letting me ride back with them, and for everyone in the group who so generously shared their great, collective knowledge of botany, photography, and natural history. What a fun day!

2019 WGNSS Nature Photo Contest

Last night the Webster Groves Nature Study Society (WGNSS) held their 2019 Nature Photo Contest, and I was fortunate to have a 1st place winner in the ‘Plants and Fungi’ category! This photograph of grassleaved lady’s tresses orchid (Spiranthes vernalis) flowers was taken at Taberville Prairie Natural Area in St. Clair Co., Missouri. Like other species of lady’s tresses orchids, their tubular flowers are arranged in a spiral along the inflorescence and cross-pollinated primarily by long-tongued bees (e.g. bumblebees, Bombus spp., and megachilid bees) (van der Cingel 2001).

Spiranthes vernalis (spring lady's tresses)

Grassleaved lady’s tresses orchid (Spiranthes vernalis), Taberville Prairie Natural Area, St. Clair Co., Missouri.

Spiranthes is one of the more complex genera of North American orchids, with seven species known to occur in Missouri (Summers 1985), and like almost all orchids, their pollination biology is fascinating! The flowers are “protandrous”, i.e., they are functionally male when they first open and become functionally female as they age. Since they open sequentially from the base of the inflorescence as it grows, this results in female flowers on the lower portion of the inflorescence and male flowers on the upper portion.  Thus, bee pollinators tend to act as pollen donors when visiting lower flowers and pollen recipients when visiting upper flowers.  Male pollinia are attached to the bee’s proboscis as it tries to access the nectar secreted into the base of the floral tube and then come in contact with the female stigma in the next flower that the bee visits.  Bees generally start at the bottom of an inflorescence when visiting a plant and then spiral up to the top before flying to the next plant.  Such “acropetal movement” is likely a result of the tendency for nectar rewards to be greater in the lower flowers, and it ultimately promotes cross-fertilization between neighboring plants.

This was the 4th edition of the contest, which has been held every other year since the inaugural edition in 2013. I’ve earned 2nd and 3rd place honors in the plants category each time before; however, this was my first win in that category. In addition to plants, I also had entries in the ‘Invertebrates’ (restricted to photos taken in Missouri or one of its contiguous states) and ‘Travel’ (open to photos taken anywhere in the world) categories, with one photo each making it to the final round of judging. You’ve seen them both before—Neotibicen superbus (below left—photographed at Mincy Conservation Area, Taney Co., Missouri) and Agrilus walsinghami (below right—photographed at Davis Creek Park, Washoe Co., Nevada). In the end, however, they both got beat out by the competition, so I only had the one winning photograph this time. Nevertheless, it was a 1st place winner, so I am very satisfied.

The WGNSS Nature Photo Contest has quickly become one of the organization’s marquee events, with the number of entries, caliber of competition, and attendance all exceeding the previous three editions. My thanks to the judges who volunteered their time, the attendees who supported the event, and especially to Bill Duncan, Chair of WGNSS’s Nature Photography Group (and an expert nature photographer in his own right), who worked hard to make this event the success that it was (and took home some well-deserved wins of his own). I look forward to the next competition in 2021!

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.

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.

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!).

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.

Art saw Gyascutus caelatus here previously, so we came back and found them abundantly in sweet acacia (Acacia rigidula), which was in full bloom. They were extremely flighty and hard to catch, so we each got only four. I also collected one Stenaspis solitaria on the same and a Trachyderes mandibularis female in flight.

At another spot nearby, we stopped to look for Lampetus webbii, which Art had seen but not been able to collect when he was here a couple of weeks ago. We did not see any (but read on…), and I saw but did not collect a Trachyderes mandibularis and two Stenaspis solitaria. I also saw and photographed some giant mesquite bugs (Thasus neocalifornicus).

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.

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.

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.

No photo description available.

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.

Cool temperatures and a blustery wind discouraged most insects from finding our blacklights. However, our blacklight did find some other interesting local residents. These two individuals could be the stripe-tailed scorpion, Paravaejovis (Hoffmannius) spinigerus, a common species in Arizona and southwestern New Mexico.

Day 5 – Miller Canyon Recreation Area, Huachuca Mountains, Arizona
There was a lot of Baccharis sarothroides growing in the lower canyon near the parking area, so I checked it all out hoping to find Tragidion annulatum. None were seen, and in fact there was very little insect life in general. I did pick up a couple of Acmaeodera solitaria by sweeping – not anything significant but the 15th species buprestid of the trip and found a dead Cotinis mutabilis, and Art got a nice series of Chalcolepidius click beetles on B. sarothroides and Prosopis glandulosa. Puzzling the lack of insect activity, given how green all the plants were and how fresh the growth looked. I guess we’ll have to look elsewhere.

Vicinity Naco, Arizona
We decided to try some desert thorn-scrub habitat so headed east towards Bisbee. Just north of Naco we saw some habitat where it had rained recently – everything was green with the sweet acacia (Acacia rigidula) and creosote (Larrea tridentata) in full bloom. Immediately out of the car I found a Dendrobias mandibularis on Baccharis sarothroides (and when I came back to it later I found a big, major male on it – see photos). On the sweet acacia we found a handful of Gyascutus caelatus (one of which I got a nice photo of), a mating pair of Sphaenothecus bivittatus, and a Cymatodera sp. Finally, out along the roadsides a riot of different yellow composites were in full bloom, including Heliomeris longifolia off which Art got a couple of Acmaeodera solitaria and I got two specimens of a large Acmaeodera sp. (blue-black with numerous small irregular yellow spots).

Vicinity Tombstone, Arizona
We decided to go back to the spot north of Tombstone where Art had earlier seen Lampetis webbii and give that species another shot. We looked at the Rhus sp. tree that he’d seen them on, and then we each followed the wash in opposite directions looking at the Rhus trees along them, which growing above the banks but never further away than about 25 feet. Along the way I collected several more Gyascutus caelatus on sweet acacia (Acacia rigida), which were more abundant this time than last and also easier to catch. After walking about 1/4-mile down the wash I saw something fly from a Rhus tree and land low on the bushes nearby. I quickly netted it, pulled it out, and was elated to see that it was, indeed, Lampetis webbii! I searched the Rhus in the area more carefully but didn’t find any more, then found some Rhus growing up along the road. At one point, I saw a large buprestid fly and land high in the top of another Rhus tree. I couldn’t tell for sure if it was L. webbii, but I extended my net as far as I could, positioned it beneath the beetle, and tapped the branch hoping it would fall in. Unfortunately, it flew away instead of dropping, so I can’t say for sure whether it was L. webbii or just a wayward G. caelatus. At any rate, L. webbii is yet another species that I have not collected before now and the 17th buprestid species of the trip.

Ramsey Canyon, Huachuca Mountains, Arizona
After returning from Tombstone, we visited Pat & Lisa Sullivan at their home at the end of Ramsey Canyon. Pat is a scarab collector who runs lights at his home nightly, and after a delicious dinner we spent the rest of the evening checking the lights. I was hoping to collect Prionus heroicus, and I got my wish. Also got Prionus californicus and several other non-cerambycid beetles such as Chrysina beyeri, C. gloriosa, Lucanus mazama, and Parabyrsopolis chihuahuae (the latter a first for me). I also placed a prionic acid lure (thanks Steve!) and got three more male P. heroicus. We also hunted around the rocks and roadsides hoping to find Amblycheila baroni but didn’t find any. Art did, however, find a female P. californicus and gave it to me (thanks!).

Day 6 – Vicinity Sonoita, Arizona
Unsuccessful attempt to collect Hippomelas martini, only recently described (Bellamy & Nelson, 1998) and part of the type series taken somewhere near this spot (“20 mi NE Patagonia, Hwy 82”) by “sweeping roadside vegetation”. At other locations it had been recorded on Calliandra sp., and I found patches of the plant here along and on top of the road cuts. This gives me confidence that I found the right spot, but I didn’t encounter this or any other beetles by sweeping the patches or visually inspecting them.

Box Canyon, Santa Rita Mountains, Arizona
We decided to come back to Box Canyon since we’d had such good luck last time. I started at the spot above the dry falls where I collected so many Acmaeodera cazieri and A. yuccavora on flowers of Allionia incarnata. This time it was hotter, drier, and windier, and the flowers were semi-closed. Still I found a few of each. I then started walking down the road towards the lower canyon crossing where I would meet up with Art. Things were really hopping on the Mimosa dysocarpa, with Hippomelas planicauda abundant (finally collected my fill) and several other Buprestidae also beaten from the plants: Agrilus aeneocepahlus, Acmaeodera scalaris, Acmaeodera cazieri, Chrysobothris sp., and a species of Spectralia! (seven species of Buprestidae at one location I think is the high for the trip.) I checked other plants and flowers along the way down but didn’t find much.

Lower Madera Canyon, Santa Rita Mountains, Arizona
Madera Canyon is perhaps the most famous insect collecting locality in Arizona – maybe in the country, and it is hard to make a visit to Arizona without stopping by here. We elected to work the lower canyon first in an area where Chrysobothris chalcophoroides has been taken on Arizona oaks (Quercus arizonicus). Hiking towards the oaks I found some Stenaspis solitaria in a Baccharis sarothroides and marveled at the variety of other insects active on the plants (see photos) – later I would also collect an elaphidiine cerambycid on the plant. Next I started working the oaks, beating every branch I could reach with my net handle. With one whack of the stick a single Paratyndaris sp. and a single Brachys sp. landed on my sheet – those would be the only buprestids I would collect off the oaks! Other than that I collected one Hippomelas planicauda on Mimosa dysocarpa for the record. While I was working the oaks up in the knoll, the weather started turning with blustery winds, and I could see the rain coming in the distance. By the time I got down from the knoll the rain had arrived, and I walked back to the car in a sunny downpour using my beating sheet as an umbrella!

Montosa Canyon, Santa Rita Mountains, Arizona
Just to try something different, we went to Montosa Canyon – the next canyon south of Madera Canyon – for tonight’s blacklighting. We set my sheet up just E of the crossing and Arts ground units back to the west along a gravel road on the south side of the crossing. Moths came in numbers, but the beetles were light – I collected only blister beetles (Epicauta sp.) and a Cymatodera sp. checkered beetle at the sheet, a series of tiger beetles and a female Strategus cessus at the second ground unit, and a male Strategus aloeus and two Stenelaphus alienus at the third ground unit.

Day 7 (last day) – Vicinity Continental, Arizona
There was a photo posted on BugGuide of Stenaspis verticalis taken last week, so we decided to give it a shot and see if we could get lucky and find it ourselves. We checked all the Baccharis sarothroides within ½-mile if the spot but didn’t find it. I did, however, collect four Euphoria leucographa, two Chalcolepidius smaragdula, two Aneflus spp., and singletons of Stenaspis solitaria and Dendrobias mandibularis. I also took a couple of Hippomelas planicauda on 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.

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!

Image may contain: cloud, mountain, sky, outdoor and nature

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.

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 (which are usually posted real time on Facebook, along with short narratives) 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.

Photo

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.

Image may contain: sky, nature and outdoor

Going east on Hwy 380 we went into an area of higher elevation with junipers. We stopped to check the Thelosperma flowers, but there were no bups on them. I collected a few noisy cicadas and some Acmaeodera quadrivittatoides on Opuntia flowers. I then started beating the junipers, however, and got a fair series of a small green Gyascutus plus two tiny Chrysobothris. They were extremely difficult to collect – winds were very stiff and the beetles were very active. I probably lost as many as I collected. To finish off I found a mating pair of Moneilema sp. on cholla.

In addition the the Tragidion larvae that I collected two stops back, Jeff saw one adult at the previous stop. So, when we saw thick stands of yucca along the roadsides just a few miles down the road we stopped to take a look. They were out and not uncommon on the flower stalks and down in the basal rosettes. I collected about a dozen of them and also another Gyascutus.

At the last stop we noticed a lot of emergency vehicles rushing to the east. Just a couple of miles down the road we ran into an accident blockade. Since we were stopped I was tempted to look at the Rick 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!

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.

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 3 Batyle suturalis ssp. on an unidentified yellow comp.

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.

Day 4—Mescalero Sand Dunes, New Mexico

We noticed a stand of soapberry (Sapindus drumondii) along the sides of the road just west of the entrance to Mescalero Sands Recreation Area last night, and I immediately thought of Agrilus sapindi, so this morning on our our way to the dunes we stopped by. I started beating the flowering branches of the larger soapberry trees but wasn’t really getting anything. Then I noticed an A. sapindi flying to a low non-flowering plant, so I caught it and resumed beating – now with more gusto knowing they were here. I still wasn’t getting anything and, again, saw another adult fly and land on a low non-flowering plant. Lesson learned – I started sweeping the low plants and started getting them. I worked all five stands in the area and got about 3 dozen adults, plus a few A. ornatulus, one A. limpiae, and spectacular Neoclytus.

After finishing with the soapberry, Jeff had noticed some tiny Acmaeodera on an unidentified white-flowered composite. We started searching in earnest and collected several dozen adults. I’m not sure what they are, but they are tiny and vittate (maybe A. quadrivittatoides). We also did a lot of sweeping of the short shrubby oak also and came up with a couple of Brachys. Overall a great morning/early afternoon in the field!

We next went into the Recreation Area proper to each lunch, after which we explored the rest of the area accessible by vehicle and saw a stand of cottonwood back in the dunes. We got out to see if there might be any Buprestidae on them (e.g., Poecilonota), but they were devoid of insects. The midday heat on the dunes was extreme! I did find, however, a single Prionus elytron lying on the sand beneath the cottonwoods, so we know they are further back in the dunes as well.

We worked the variety of blooming plants in the vicinity of the entrance. I collected ~22 of the small Acmaeodera that were on the white-flowered plant at the soapberry spot on two blossoms of a single yellow-flowered pad Opuntia sp., a couple of Acmaeodera spp. on Gaillardia sp. flowers, a few more Acmaeodera spp. on Prosopis, and several Acmaeodera mixta on another as-yet-unidentified white flower. It was hotter than bejesus we later learned 103°F!) – I had wanted to check out one more stand of soapberry at the entrance, but we were exhausted and dehydrated and had to quit!

Vicinity Hobbs, New Mexico
We got a hotel in Hobbs and grabbed a sandwich for dinner, then went out west of town to see if we could find some good habitat for evening collecting. We found a spot of open rangeland about 8–9 miles west of town, set out the pheromone lures, and began beating the mesquite (Prosopis glandulosa). We had high hopes because there was still standing water, meaning that the area had gotten good rains on Sunday night. Boy were we correct! Beating the mesquite was amazing. For buprestids I got 10 individuals of an Actenodes sp., 4 individuals of a Paratyndaris sp., 4 Chrysobothris spp., 4 Acmaeodera spp., and 1 Agrilus sp. I also got several tiny cicadas, a couple treehopper species, and a few clerids and other odds and ends. We setup a blacklight and the scarabs were quite diverse, but the only thing I took was a tiger beetle (Cylindera lemniscata). I also picked up a Phyllophaga cribrosa and a tenebrionid walking on the ground at night. No Prionus came to the lures, any my searches of the ground at night turned up no Amblycheila.

Day 5—Sand Dunes near Kermit, Texas
We stopped just outside the Kermit Sand Dunes to beat the mesquite (Prosopis glandulosa) to see what might be out. I collected 8 species of Buprestidae: nice series of an Acmaeoderopsis (hoping A. prosopis), 1 sp. Actenodes, 2 spp. Chrysobothris, 1 sp. Paratyndaris, 1 sp. Agrilus, and 2 Acmaeodera spp. We eventually gave up – the heat had not only wilted us, but the Acmaeoderopsis were flying away immediately upon hitting the sheet.

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.

San Felipe Park, near Fabens, Texas
We took a chance on going further west to the dunes near Fabens, since we’ve had such good luck with rains in the area. However, when we got here and started looking around it was apparent that nothing was happening here – dry, dry, dry with temps just over 100°F. I saw a few insects but only a single buprestid – Acmaeodera quadrivittatoides, and I missed it! We decided to cut bait and head back east and north towards Carlsbad – we should be able to get to the area in time for some late afternoon and evening collecting. You can’t win ‘em all!

Vicinity Carlsbad, New Mexico
After getting lost in the Fabens Sand Dunes and then a whole lot of driving back east into New Mexico, we arrived in Carlsbad with just enough time to grab a sandwich and head out to some promising habitat we’d noticed on the way in for some evening/night collecting.

The area contained a ribbon of woodland with mesquite (Prosopis glandulosa), black acacia (Acacia rigida), and catclaw acacia (A. greggii). I beat only one tiny Chrysobothris sp. off the mesquite, but off the black acacia I beat three individuals (four actually, one got away) of a large, chunky Chrysobothris sp. that I do not recognize, plus an undetermined cerambycid and a few clytrines. Actually, before I collected the Chrysobothris I had given up on the lack acacia until I was walking by one plant and saw the first one sitting on a branch. I popped it in the vial and started beating the other plants in the area with renewed enthusiasm the find the other two (three!).

We setup the lights and the pheromones, but not much came to the former and nothing to the latter (expected, since there was no sand habitat nearby). The sunset beforehand, however, was magnificent, and I did find a couple of miscellaneous beetles walking around at night.

Day 7—vicinity Loco Hills, New Mexico
We saw an area with stands of soapberry (Sapindus drummondii) alongside the road so stopped to sample it for Buprestidae. I got 3 Agrilus limpiae on trees right around the car but nothing on all the rest of the three stands nearest the car on either side of the road. I hope the south area of Mescalero Sands is not as dry as it still appears around here.

Mescalero Sand Dunes, New Mexico
We found the central dunes of the southern area and immediately found several Acmaeodera mixta adults on mesquite (Prosopis glandulosa) flowers. I started beating the mesquite and picked up a nice series of Acmaeoderopsis, one Actenodes, and a few other miscellaneous Acmaeodera off the larger trees. There was some soapberry (Sapindus drummondii) in bloom around the dunes, but beating it produced no Buprestidae.

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!

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!

For the final stop for the day we returned to Valley of Fire Recreation Area – not really to collect insects, but to look about this fascinating landscape. The Lava Beds are thought to be 5,000 years old, having formed over a 30-year period when lava poured from Black Peak to the north (not a volcano, but a volcanic vent) at a rate that would fill 15 bathtubs every second! It was a serene and otherworldly walk in the falling darkness – nice way to cap off an evening.

Day 8—vicinity Bingham, New Mexico and west on Hwy 380
We stopped at another yucca stand very near where we’d found the Tragidion armatum last weekend – no problem finding them here either. I got plenty of photographs of the beetles (despite having to go ‘au natural’ with the lighting – my flash unit had died!), as well as of cicadas, wasps, and other insects on the yucca stems and pods. Otherwise I only collected two Acmaeodera (looks like A. immaculata) on flowers of Sphaeralcea sp., what looks to be A. disjuncta/paradisjuncta on Ephedra sp., and a single Moneilema sp. on Opuntia imbricata. Nice stop!

We then stopped by “the juniper spot” again to see if I could get a better series of the Gyascutus (G. carolinensis?) that we found on the junipers (Juniperus monosperma). Boy, did I ever! I collected about 30 specimens this time, made easier by the fact that it was cooler and not nearly as windy! I also again collected two small Chrysobothris sp. on the juniper, a single Moneilema sp. on cholla (Opuntia imbricata), and a single Acmaeoderopsis sp. beating mesquite (Prosopis glandulosa).

We stopped at another spot further west on Hwy 380, where last weekend when we were here we saw few beetles but I did collect yucca stems infested with Tragidion armatum larvae. It rained here later that day, so we stopped by again on our way back to see if the rains had prompted more insect activity. It didn’t seem to, but I did find a Tragidion armatum adult feeding on a yucca flower and photographed a big-as-heck katydid.

“The Box”, vicinity Socorro, New Mexico
Last stop of the trip – we just wanted to find some habitat to beat around in before finding a hotel in Socorro for the night. I beat a couple of small Chrysobothris sp. from the Juniperus monosperma – no Gyascutus – and a couple of treehoppers from Prosopis glandulosa – no Acmaeoderopsis, then turned my attention to the cholla (Opuntia imbricata), in what must have been the thickest stand of this plant I’ve ever seen. There were two species of cactus beetles on them – Moneilema sp. and Coenopoeus palmeri, the latter a first for the trip. After hiking up to the canyon overlook, I realized that the collecting and fun were finally over (until Arizona in August!).

Fun with eucraniines!

During my February/March 2015 visit to Argentina, I had the opportunity to travel to west-central provinces of San Juan and San Luis with Federico Ocampo for a weekend of insect collecting. Up to that point most of my collecting in Argentina had been limited to the northeastern provinces (Chaco, Corrientes, and Misiones), so I was excited for the chance to explore a radically different biome. West-central Argentina represents a transition zone from the flat, wet, treeless plains of the Humid Pampas in east-central Argentina (Buenos Aires, Santa Fe, and Córdoba Provinces) to the massive Andes Mountains running along the western edge of South America. This area is home to the Monte, a desert biome characterized by volcanic sediments, piedmont plains, large mountain blocks and dry salt lakes. Conditions in the Monte are generally more hospitable than in the neighboring Atacama and Patagonian Deserts lying north and south of the Monte, respectively. As a result, the flora and fauna in the Monte is relatively rich and characterized by a diversity of shrubs, grasses, and cacti.

Dunas de Encón

Encón Dunes, San Luis Province, Argentina

Of the several sites we visited in the area, the most remarkable was “Las Dunas de Encón” (the Encón Sand Dunes) in San Luis Province. Belonging to a larger system covering some 250,000 hectares—the largest in South America (and, thus, sometimes called the “Argentinian Sahara”)—the dunes are thought to have formed some 100–200K years ago as a result of dry conditions brought on by Quaternary glaciations. I find sand dune systems endlessly fascinating due to their unique and often endemic plants and animals and have visited many systems in North America (Bruneau, Coral PinkGlamisGreat, Medora, St. Anthony, and others), but this was the first sand dune system I’ve had the opportunity to see outside of the U.S. Federico, a scarab specialist, shares that fascination and has, in fact, described a number of species in the scarabaeine tribe Eucraniini—endemic to South America—that utilize these very sand dunes (Ocampo 2005, 2007, 2010). He was hoping one or more of them might be out and about; I was hoping to see anything, really.

Host for Lampetis spp.

Parkinsonia praecox? – adult host plant for Lampetis baeri and L. corinthia.

One of the first plants that caught my attention was a woody, fabaceous shrub that looked very much like what I would have previously called Cercidium, now Parkinsonia, and which after a bit of digging I conclude is likely Parkinsonia praecox. Woody, fabaceous shrubs in desert habitats are a sure bet to host jewel beetles, so I began paying special attention to each shrub as I wandered by. It wasn’t long before I saw a large, brilliant metallic green jewel beetle sitting on an outer branch of one of the shrubs—it was one of the most beautiful jewel beetles I have ever seen out in the field with my own eyes! I managed to catch it, and over the next few hours I collected not only several more of this species but also several individuals of an even larger, more somber-colored species. I was able to identify them as Lampetis baeri (Kerremans, 1910) and L. corinthia (Fairmaire, 1864), respectively, when I compared them to material in the collections at Fundacion Miguel Lillo, Instituto de Entomologia, Tucuman, Argentina [IFML]) during my visit there the following week (see photos below).

As a jewel beetle enthusiast, you would think that was the highlight of my day. In fact, the fun had only started. For a time after our arrival, Federico pointed out burrows likely made by eucraniine adults, but we didn’t see any evidence of activity at first. It wasn’t long, however, before we found the first adult—a fine Eucranium beleni Ocampo, 2010, the largest of the three species occurring at this site (about the size of our North American Deltochilum). One of the more obvious features of eucraniines is their enormously enlarged forelegs and pronotum to hold the musculature required to carry—that’s right, carry!—provisions to the larval burrow (in contrast with the more commonly seen habit among members of the subfamily of using the hind legs to push provisions to the burrow). This unusual morphology gives these beetles not only an amusing, shuffling gait but also a rather comical method for turning themselves upright (as seen in this video narrated by Federico). There are other dung beetles that pull, rather than push, larval provisions (e.g., Sisyphus spp., which stand on highly elongate hind legs and walk backwards while pulling the dungball), but eucraniines seem to be the only ones that actually lift provisions off the ground to carry them. In the case of E. beleni, this involves carrying pieces of dung with the forelegs held out in front of the head while walking forward on the middle and hind legs (Ocampo 2010). I didn’t get to see that behavior with E. beleni, but I did see it with one of another of the eucraniines we found that day (see below). In the E. beleni photo below, note the brushy middle and hind tarsi—an adaptation for walking on loose sand.

Eucranium belenae

Eucranium belenae Ocampo, 2010 walks on its middle/hind legs while holding its forelegs aloft.

Eucranium belenae burrow

The second species in the group that we encountered was Anomiopsoides cavifrons (Burmeister, 1861). This species is much smaller than E. beleni (about the size of a large Onthophagus), and unlike E. beleni—and, in fact, most other dung beetles—the larvae of A. cavifrons develop on plant matter rather than dung. Both males and females provision the larval burrows with pieces of plant debris that they pick up with their front legs and carry back to the burrow while walking on their other four legs. This rather amusing video shows a male bringing a piece of debris back to his burrow, then exiting to find and retrieve another piece of debris to bring back to the burrow. The molar region of their mandibles is heavily sclerotized for masticating the plant fibers in preparation for the larvae. There are a couple of other species in the tribe that opportunistically include plant matter in their diet, but A. cavifons seems to be the only one known to utilize dry plant matter in desert habitats almost exclusively (Ocampo 2005). Anomiopsoides cavifrons was far more abundant in the dunes than E. beleni, and by early to mid-afternoon they were encountered with such regularity that I stopped even looking at them.

We also were fortunate to see a few individuals of the third species known from these dunes, Anomiopsoides fedemariai Ocampo, 2007. This species is intermediate in size between the extremes represented by E. beleni and A. cavifrons and utilizes pellets of the plains viscacha (Lagostomus maximus), a species of rodent in the family Chinchillidae, for food (Ocampo 2007).

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.

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.

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.

Eventually the rising sun began to burn through the cool, damp fog, portending another day of searing heat in the xeric glade landscape.

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.

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 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.

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!
