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.

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).
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.
Tingler Lake – the centerpiece of Tingler Prairie Natural Area.
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.

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.

These diminutive plants are distinguished from other members of the genus by their short stature and sepals with midline beards.

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.!).

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!

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!

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 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!

In my previous post, I talked about a day trip to a sand scrub remnant in the Lake Wales Ridge of central Florida to find and photograph the endemic Highlands tiger beetle (Cicindelidia highlandensis). Ironically, the dry sand scrub/pine woodland habitats along this ridge are dotted with small lakes and ponds, allowing a rich aquatic flora and fauna to co-exist alongside the xeric specialists. Field mate Chris Brown and I had found and just finished photographing the tiger beetles when we encountered this rather largish lake—bright, white sand surrounding crisp, clear water reflecting white, puffy clouds in a deep, blue sky. ‘Twas a spectacular sight, indeed!

As we stood looking at the scenery, I noticed something black on the stem of one of the sedges growing along the water’s edge. Something big and black! As I moved closer I could tell quickly that it was a large horse fly, but it was not simply perched and resting on the sedge—there was something else going on. Moving closer, ever so cautiously so as not to disturb the fly, I eventually realized that it was a female in the act of oviposition. How cool—I’d never witnessed this before with any species of horse fly, so to see it with such a large species was a real treat. I recognized it instantly as Tabanus atratus—commonly called the black horse fly and recognizable as such by its large size, all-black coloration, and distinctively hooked antennae (see 3rd photo below).
A Tabanus atratus female oviposits on a stem overhanging the water.
Before we get to the eggs, let’s dispel some misinformation that seems to persist regarding the size of this species (as it does with almost any large insect). Black horse flies are undeniably large, and in fact they are one of the largest horse flies in North America. The more credible sources (e.g., Pechuman et al. 1983, Long 2001) cite body length as ranging from 20–25 mm (up to a full inch in length). Incredibly, the species does not take the honors as North America’s largest horse fly, which goes instead to Tabanus americanus and it’s upper limit of 30 mm (in fact, T. americanus may be the world’s largest horse fly)! There are, however, on-line sources and a few popular field guides (as cited in BugGuide) that state a maximum length of 28 mm for T. atratus. How credible this figure is I cannot say, but I guarantee that the size indications of 30, 40, and even a whopping 50 mm in length found routinely among photos of this species on BugGuide were not derived from careful measurement and almost certainly instead reflect the astonished reactions that such an abnormally large insect can generate! In fact, there are precious few insects in North America that reach lengths as grand as 50 mm (i.e., two full inches)!
Lateral view of oviposition.
We approached carefully, again so as not to disturb the female in the middle of her act, and we watched and photographed as she laid the individual eggs one by one, using the tip of her abdomen to carefully arrange them neatly against each other in stacked layers. From a photographic perspective, balancing flash exposure of the all-black adult with the bright-white egg mass presented a real challenge. Added to that was an additional exposure challenge (my desire for a blue-sky background), making it a truly difficult-to-photograph subject. Long (2001) states that T. atratus egg masses can contain anywhere from one hundred to a thousand eggs each, always near water’s edge or somewhere quite close to water. Females are capable of laying three or four of these egg masses, which apparently gradually turn dark as the eggs develop and approach hatch.
Freshly laid Tabanus atratus egg mass.
Despite this being the first time I’ve ever witnessed oviposition by this species, it seems to be encountered regularly. There are several photos of ovipositing females among the many photos of this species that have been posted to BugGuide. Moreover, descriptions of the egg mass of T. atatus appeared very early in the literature, first by Hart (1895) and then in photographs by Schwardt (1936). The latter author also states “T. atatus deposits its eggs in masses which are so constant in structural plan as to make specific determination of the egg mass readily possible” (as quoted in Bailey 1948). Thus, even if this female had already finished and left her egg mass, it still could have been identified to species.

In September 2016, I had the opportunity to attend the Annual Meeting of the Entomological Society of America in Orlando, Florida, which was being held in conjunction with the International Congress of Entomology. My first thought when I made plans to attend these meetings was that this would be a chance for me to get another look at the Highlands tiger beetle (Cicindelidia highlandensis). One of Florida’s rarest endemic tiger beetles, this species is restricted entirely to remnant sand scrub and pine woodland habitats along the Lake Wales Ridge of Polk and Highlands Counties in central Florida (Choate 2003). I was thrilled to have found adults (in good numbers) on my first attempt back in 2009, and I was also thrilled to have successfully managed to photograph the beetle at that time. However, in the years since, I have become increasingly dissatisfied with those photographs—taken during what was my very first year of insect macrophotography. I’ve learned a lot since then about lighting, diffusion, and composition, but perhaps the biggest annoyance of those photographs is the fact that in every one the antennae and/or legs are “clipped”—a result of my being so enamored with my newfound macrophotographic capabilities that I nearly completely ignored other aspects of photographic composition.
Chris Brown photographs a Highlands tiger beetle.
Chris Brown—long-time field accomplice and himself a tiger beetle aficionado and insect macrophotographer—was also at the meetings, and since he had never seen the Highlands tiger beetle before we made plans to slip away one day and visit the spot where I had seen them back in 2009. I knew our chances of finding them were slim—it was very late in the season (late September), and the species is a so-called “summer species” with peak of adult activity in July and August. We figured, however, that even if we didn’t find adults we would still enjoy the day in the field, and for some time after arriving at the site that’s all it was. Finally, in an open sandy area near a small lake we saw the first adult. I let Chris take his shots, as this was his first opportunity (see photo above), while I continued to search for additional adults. Eventually I found one and began the long process of “whispering” to it to coax it into allowing me the photographs I desired.
As you can see in the photograph above, my compositional preferences have changed since I took those first photographs back in 2009. In contrast to the “as close as possible” style that I initially adopted, I now prefer to back off from the beetle enough to include elements of the habitat in which it occurs. While this compositional style may show less detail on the beetle itself, I believe it adds perspective and results in a more interesting and aesthetically pleasing photograph. I also now like to get down as low as I can, often placing the camera directly on the ground rather than always shooting from “elbow-height”, for a more unique perspective of the beetle, and my use of better flash diffusion results in more even lighting and minimizes the distracting specular highlights that are often the hallmark of flash macrophotography.
This individual demonstrates the thermoregulatory “stilting” behavior of the adults.
Sadly, my flash unit failed soon after I began photographing the beetle, which is a real shame because the beetle began demonstrating the characteristic “stilting” behavior that the adults use for thermoregulation in their hot environment. The photograph above is the only one that I could “rescue” through some rather heavy-handed post-processing to make up for the failure of the flash unit to fire (it is fortunate that I have shifted to routinely using a combination of ambient light and fill-flash rather than flash only, or I would have had not even this photograph to rescue!). I suppose this means I’ll just have to revisit this species once again (now that I have not one but two new flash units!), which isn’t all bad because I would also love to see and photograph once again the moustached tiger beetle (Ellipsoptera hirtilabris), another Florida endemic (or near so) that I saw here also during my first visit but not during this one.
The Highlands tiger beetle belongs to a group of species called the abdominalis species-group, with all four of the included species (C. abdominalis, C. floridana, C. highlandensis, C. scabrosa) occurring in Florida (three of which are endemic or near-endemic to Florida). For those interested, I have seen and photographed all four of the species and presented a “mini-review” with photographs and links to posts with more detailed information about each species, along with a key to the species to allow for their identification.

My love affair with the bumelia borer, Plinthocoelium suaveolens, has been well-chronicled on this blog. The combination of its large size, striking iridescent green elytra, brilliant coppery head and pronotum, and marvelously elongate antennae and legs – both black but the latter with contrasting orange femora – even led me to declare it as “North America’s most beautiful longhorned beetle“. For all its charisma, however, I never did succeed in getting field photographs that I felt did justice to the beauty of this wary and difficult-to-approach species. Yes, I did photograph a live adult in a white box, a technique that is especially useful for such colorful subjects. However, I still desired that ‘perfect’ photo of a live adult, unconfined in the field on its host plant.
Plinthocoelium suaveolens – photographed 29 July 2017 on foliage of living Sideroxylon lanuginosum at Shaw Nature Reserve, Franklin Co., Missouri.
Some years would pass before I gave photographing this species another try. In 2015 and 2016, I discovered healthy populations of the species at two locations surprisingly close to my home while conducting fermenting bait trap surveys – one at Shaw Nature Reserve in Gray Summit, Missouri (just 14 miles from my home), and the other at Victoria Glades Natural Area near Hillsboro, Missouri (slightly further away – only 40 miles from my home). During these surveys, I not only caught the beetles in my traps, but I was able to find them on their host plant, Sideroxylon lanuginosum (gum bumelia), and learn their habits and behavior – important to know when trying to photograph living, unconfined insects. Still, it wasn’t easy! On 29 July 2017, I and several other nature photographers went to Shaw Nature Reserve to find and photograph this species, and through our collective efforts we found only a single individual – at first resting high up on the foliage of a living tree but later flying down to a branch that was (just barely) within reach of our lenses. I used my 100-mm macro, and the photograph above is the only one that I was satisfied with – yes, the tips of the elytra and left hind leg are somewhat obscured, but exposure is good, the focus spot on, and the background a pleasing blur of green that contrasts nicely with the sharply iridescent beetle (achieved with settings that allowed a combination of ambient light and flash illumination of the subject).
Plinthocoelium suaveolens – photographed 29 July 2017 on a dead branch of Sideroxylon lanuginosum at Victoria Glades Natural Area, Jefferson Co., Missouri.
My luck turned later that day when I went down to Victoria Glades to check my fermenting bait traps – and found an adult on the trunk of one of the trees in which a trap was hanging! In this case, I was able to use my “beetle whisperer” skills to coax the beetle onto a dead branch of the tree and positioned it with the sky in the background. As the beetle roamed back and forth on the branch (rarely stopping!), I used the “left hand technique” to keep it in the frame and fired a shot after shot, hoping against hope that I would get at least one in which all of the required elements – exposure, lighting, focus, and most importantly composition – were what I wanted. And that is exactly what I got – one photograph (out of about 75 shots) in which all of those elements worked (second photo above)!
Some may snicker at my spending a whole day just to get two photographs of a single species, but I relish the challenge and enjoy the satisfaction of knowing that these photographs represent field photographs of live, unconfined beetles. Could I do better? Sure, and I will probably try again sometime. But for now, these will do.
Hot on the heels of the previous installment in this series, I present the sixth “Collecting Trip iReport”; this one covering a trip to Arizona during July/August 2018 with Art Evans and—like the previous installments in this series—illustrated exclusively with iPhone photographs (see previous installments for 2013 Oklahoma, 2013 Great Basin, 2014 Great Plains, 2015 Texas, and 2018 New Mexico/Texas).
This trip was a reunion of sorts—not only had it been 20 years since I’d collected in Arizona, it had also been 20 years since I’d spent time in the field with Art Evans—which just happened to be in southeast Arizona! For years I looked forward to our next opportunity, and when he told me of his plans for an extended trip to take photographs of his forthcoming Beetles of the Western United States, I couldn’t pass up the chance. Art had already been out west for five weeks by the time I landed in Phoenix on July 28th, and together we drove to Cave Creek Canyon in the Chiricahua Mountains and spent the night before beginning a 7-day adventure in and around the “Sky Islands” of southeastern Arizona.
As with the recent New Mexico/Texas post, the material collected still has not been completely processed and curated, so I don’t have final numbers of taxa collected, but there were a number of species—some highly desirable—that I managed to find and collect for the first time, e.g., the buprestids Acmaeodera yuccavora, Agrilus restrictus, Agr. arizonicus, Chrysobothris chiricauhua, Mastogenius puncticollis, and Lampetis webbii and the cerambycids Tetraopes discoideus and Stenaspis verticalis. Who knows what as-yet-unrecognized goodies await my discovery in the still unprocessed material?!
Day 1 – Chiricahua Mountains, Cave Creek Canyon
After arriving at Cave Creek Ranch late last night, we awoke to some stunning views right outside our room!

The first buprestid of the trip was a series of Pachyschelus secedens on Desmodium near Stewart Campground. We beat the oaks and acacia along the way to Sunny Flat Campground but didn’t find much. Once we got near Sunny Flat I did some sweeping in an area with new growth of Helianthus sp. and got a series of Agrilus huachucae, a few lycids, and one Leptinotarsa rubiginosa. I beat one Acmaeodera cazieri from Acacia greggii and found another on flower of prickly poppy (Argemone sp.). On the roadside at Sunny Flat I found several Acmaeodera spp. on a yellow-flowered composite – one A. rubronotata, one A. solitaria(?), and three A. cazieri. Also collected one A. cazieri on a rain gauge, Mecas rotundicollis and one as yet undetermined acanthocinine cerambycid on miscellaneous foliage, one tiger beetle (Cicindela sedecimpunctata?) on the roadside, and two orange lycids in flight.

We came to this spot to look for Sphaerobothris ulkei on joint-fir (Ephedra trifurca), but after not finding any for awhile I got distracted by some big buprestids flying around. Caught several Hippomelas sphenicus, one Gyascutus caelatus, and two Acmaeodera gibbula on Acacia rigida, and the first and third were also on Prosopis glandulosa along with Plionoma suturalis. We finally found S. ulkei – searched the area for almost three hours, and Art and I each caught two and Margarethe caught one – also one each of P. suturalis and A. gibbula. I also got a mating pair of A. gibbula on Acacia greggii. After dinner, we went back and placed an ultraviolet light – checked it a couple hours later and got a nice series of Cylindera lemniscata and a few meloids (for Jeff).

Day 1 of the trip ended in typical monsoon fashion – heavy, thunderous rainstorms moved into the area during late afternoon, dimming prospects for blacklighting. Still, we set them up anyway at several spots and checked them later in the evening (flood waters preventing us from going to all the spots we wanted to). Not surprisingly, the one trap that yielded interesting specimens was in the lowest (warmest) area and received the least amount of rain. For me it was a nice series of Cylindera lemniscata.
Day 2 – Southwestern Research Station, Chiricahua Mountains, Arizona
There is a large stand of a narrow-leaved milkweed (Asclepias sp.) at the station, so we stopped by in our way up the mountain to check it for beetles. Got a nice little series of Tetraopes discoideus (tiny little guys!) on the stems as well as a few Rhopalophora meeskei, two Lycus spp., and one Pelonides humeralis on the flowers.

Road from Southwestern Research Station to Ruster Park After leaving the SWRS on our way up to Rustler Park, we stopped to check a couple of bushes of New Mexico raspberry (Rubus neomexicanus). Margarethe thought there might be lepturines on the flowers, but instead we found a few Acmaeodera spp. and some Rhopalophora meeskei.

Further up the road we made another quick stop to check roadside flowers – just a single A. rubronotata on a yellow-flowered composite, but spectacular views of the valley below.
Looking west from the Chiricahua Mountains, Arizona.
Gayle Nelson once told me about finding Chrysobothris chiricahuae on pine slash at Rustler Park, so I was pleased to see several fresh slash piles when we arrived. I saw a Chrysobothris (presumably this species) on the very first branch in the very first pile that I looked at, but I missed it (damn!) and didn’t see any more in that pile. However, in the next pile I visited I saw two and got them both. I looked at a third pile and didn’t see any, nor did I see any more on the two previous piles that I looked at. Still, two is better than none (assuming this is, indeed, what they are!).
Rustler Park, Chiricahua Mountains, Arizona.
Chiricahua National Monument
Not a bug collecting stop, but we wanted to drive into the monument and see the incredible rock formations which are best appreciated by driving through Bonita Canyon and then up to Massai Point. The unusual spires, columns, and balancing rocks are a result of erosion through vertical cracks in the compressed volcanic ash which was laid down in layers 25 million years ago and then uplifted. Tilting during uplift caused vertical fractures and slippage, into which water then worked its way to create today’s formations. One of the columns I saw is 143 feet tall and only 3 feet in diameter at one point near the base! Mexican jays were our constant, close companions as we hiked through the pinyon pine/oak/juniper woodland.
Vicinity Gleeson, Arizona
There is a wash across N Ghosttown Trail with stands of Baccharis sarothroides growing along the sides. Art previously collected a single Cotinis impia on one of the plants, so we came back to check them. We didn’t find any, but we did find two fine males and one female Trachyderes mandibularis on a couple of the plants. I also found a dead Polycestaaruensis.
Vicinity Tombstone, Arizona
Art saw Gyascutus caelatus here previously, so we came back and found them abundantly in sweet acacia (Acacia rigidula), which was in full bloom. They were extremely flighty and hard to catch, so we each got only four. I also collected one Stenaspis solitaria on the same and a Trachyderes mandibularis female in flight.

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

The day ended enjoying steaks, Malbec, and Jameson with two of the best hosts ever!
Day 3 – Box Canyon, Santa Rita Mountains, Arizona
Our first stop of the day was Box Canyon, a gorgeous, rugged canyon on the east side of the range. Mimosa dysocarpa was in bloom, off which I beat two Agrilus aeneocephalus, several Hippomelas planicauda, and one Stenaspis solitaria. Norm gave me an Acmaeodera cazieri that he’d collected on an unidentified yellow-flowered composite, and right afterwards I found some small, low-growing plants with purple flowers and sticky leaves (eventually ID’d as Allionia incarnata, or trailing four o’clock) to which Acmaeodera yuccavora and A. cazieri were flying in numbers. After that I crawled up top and beat the mesquites, getting one Chrysobothris sp., a mating pair of S. solitaria, and a couple of large clytrine leaf beetles.

Vicinity Duquesne, Arizona
We came here to look for Tetraopes skillmani (this is the type locality). We found the host plant (Sarcostemma sp.), but there were no beetles to be seen anywhere. Maybe another location nearby…
Sarcostemma sp. (family Asclepiadaceae).
Patagonia Pass, Patagonia Mountains, Arizona We went up higher into the mountains to get into the oak woodland, where I hoped to find some of the harder-to-collect oak-associated Agrilus spp. Right away I beat one Agrilus restrictus off of Emory oak (Quercus emoryi), but no amount of beating produced anything more than a single Enoclerus sp.. I also beat the Arizona oak (Q. arizonica) and got only a single Macrosaigon sp. On Desmodium sp. I collected not only Pachyschelus secedens but a nice series of Agrilus arizonicus. For me it is the first time I’ve collected either A. restrictus and A. arizonicus, the former being quite uncommon as well, so all-in-all not a bad stop.

Sycamore Canyon, Santa Cruz Mountains, Arizona
We came here for night lighting, but while we still had light I did some sweeping in the low vegetation and collected a mixed series of Agrilus arizonicus (on Desmodium sp.) and Agrilus pulchellus – the latter a first for me, along with two small cerambyids that could be Anopliomorpha rinconia. Conditions were perfect (warm, humid, and no moon), and we had lots of lights (Art’s five LED units, Steve’s MV/UV combo setup, and my UV setup), but longhorned beetles were scarce – just one Prionus heroicus and one Lepturges sp. for me, and Steve got a few others including a nice Aegomorphus sp. I did also collect a few scarabs – Chrysina gloriosa and Strategus alous – because they’re just so irresistible!

Day 4 – Prologue One of the downsides (if you can call it that) of having great collecting is the need to take periodic “breaks” to process all the specimens and make my field containers available for even more specimens. Thanks to Steve and Norm for making their place available to Art and I so we can do this before heading out to our next set of localities.
Copper Canyon, Huachuca Mountains, Arizona
Copper Canyon is the classic spot for finding the charismatic Agrilus cavatus (see photo), but first we did some sweeping in the low vegetation near the parking area, where Norm got one Agrilus arizonicus and two Agrilus latifrons – and gave them to me! (Thanks, Norm!) I did some beating of the oaks, and after much work I ended up with a single Agrilaxia sp. and pogonocherine cerambycid on Emory oak (Quercus emoryi) and a couple of giant clytrines on the Arizona oak (Q. arizonicus). I then started sweeping the low-growing Acaciella angustissima – right away I got two A. cavatus. They were in the area past the cattle guard on the right where lots of dead stems were sticking up, and although I continued to sweep the plants more broadly in the area I never saw another one. Finally, Norm called me up to a small Mimosa dysocarpa near the car off which he collected three Agrilus elenorae – and gave them to me! (Thanks, Norm!) I gave the tree a tap and got one more, and in my last round of sweeping I came up with a Taphrocerus sp. (must be some sedges growing amongst the grasses).

Bear Canyon Crossing, Huachuca Mountains, Arizona
There was quite a bit of Mimosa dysocarpa in bloom along the roadsides on the west side of the Bear Canyon crossing, which I beat hoping to find some more Agrilus elenorae. I didn’t find any, but I did get several more Hippomelas planicauda, which is a nice consolation prize – and a great photo of the last one! Other than that I did a lot of sweeping and found only a single Acmaeodera cazieri.

Cool temperatures and a blustery wind discouraged most insects from finding our blacklights. However, our blacklight did find some other interesting local residents. These two individuals could be the stripe-tailed scorpion, Paravaejovis (Hoffmannius) spinigerus, a common species in Arizona and southwestern New Mexico.
Day 5 – Miller Canyon Recreation Area, Huachuca Mountains, Arizona
There was a lot of Baccharis sarothroides growing in the lower canyon near the parking area, so I checked it all out hoping to find Tragidion annulatum. None were seen, and in fact there was very little insect life in general. I did pick up a couple of Acmaeodera solitaria by sweeping – not anything significant but the 15th species buprestid of the trip and found a dead Cotinis mutabilis, and Art got a nice series of Chalcolepidius click beetles on B. sarothroides and Prosopis glandulosa. Puzzling the lack of insect activity, given how green all the plants were and how fresh the growth looked. I guess we’ll have to look elsewhere.

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

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

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

Day 6 – Vicinity Sonoita, Arizona
Unsuccessful attempt to collect Hippomelas martini, only recently described (Bellamy & Nelson, 1998) and part of the type series taken somewhere near this spot (“20 mi NE Patagonia, Hwy 82”) by “sweeping roadside vegetation”. At other locations it had been recorded on Calliandra sp., and I found patches of the plant here along and on top of the road cuts. This gives me confidence that I found the right spot, but I didn’t encounter this or any other beetles by sweeping the patches or visually inspecting them.
Box Canyon, Santa Rita Mountains, Arizona
We decided to come back to Box Canyon since we’d had such good luck last time. I started at the spot above the dry falls where I collected so many Acmaeodera cazieri and A. yuccavora on flowers of Allionia incarnata. This time it was hotter, drier, and windier, and the flowers were semi-closed. Still I found a few of each. I then started walking down the road towards the lower canyon crossing where I would meet up with Art. Things were really hopping on the Mimosa dysocarpa, with Hippomelas planicauda abundant (finally collected my fill) and several other Buprestidae also beaten from the plants: Agrilus aeneocepahlus, Acmaeodera scalaris, Acmaeodera cazieri, Chrysobothris sp., and a species of Spectralia! (seven species of Buprestidae at one location I think is the high for the trip.) I checked other plants and flowers along the way down but didn’t find much.

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

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

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

Lower Madera Canyon, Santa Rita Mountains, Arizona
We returned to work the lower canyon area. I’d heard that the tiger beetle Cicindelidia obsoleta santaclarae has been taken in the area last week so was hoping to run into it. While Art worked the east side of the road I worked the west, initially following FR-781 into what looked like grassland areas where the tiger beetle might occur. I didn’t see any but took Acmaeodera scalaris on Heterotheca sp. flowers and Acmaeodera solitaria on Argemone mexicana flowers. There was also a fresh wind-thrown mesquite (Prosopis glandulosa) with a bunch of Chrysobothris octocola and one Chrysobothris rossi on it. Still the area looked abused from grazing and was uninteresting, so I looked for another area to explore.
Northwest of the parking lot I spotted another grassy area that was dotted with Baccharis sarothroides, so I decided to give that area a look. After clambering several times through barbed wire fence, I reached the area and began to give it a look. Still no tiger beetles, but every time I passed a B. sarothroides I inspected it closely. I’d looked at several plants when I came upon one with a Stenaspis solitaria sitting in the foliage, and when I looked down on one of the stems and saw a big male Tragidion sp. on the underside of the stem. After securing it, I looked closer at the plant and saw a pair of annulated antennae crawling up another stem – I knew right away it was a mating pair of Stenaspis verticalis! After carefully moving to the other side to confirm, I dared to take a few photos in situ (see below) and then secured the couple. Of course, this gave me newfound motivation to work the entire area to look for more. It was very hot by then, and I was already quite thirsty, but I summoned up all the stamina that I could and worked as many plants as I could, ending up with six Tragidion spp. and three Stenaspis verticalis. The latter was one of my top priority targets for this trips, and the only thing more satisfying than getting it is doing so on my last day on the field.

Montosa Canyon, Santa Rita Mountains, Arizona
We returned to Montosa Canyon and stopped at the Astronomy Vista partway up. It was hotter than bejeebuz! There was not an insect to be seen except giant cactus bugs and a single Euphoria leucographa that Art found on a sapping Baccharis sarothroides. Temp was 103°F even at this elevation!
Stunning vista during the day!
We needed to escape the heat, and I wanted to see oaks for one more crack at Mastogenius, so we drove up to the 13-km marker and I collected on the way back down to below the 12-km marker. Conditions were much more agreeable (temps in the 80s), and near the top there was a Ceanothus sp. bush in bloom, off which I collected Rhopalophora meeskei and Stenosphenus sp. – both genera represented by individuals with black versus red pronotum. Then I started beating the (Mexican blue, I believe) oaks, and right away I got a Mastogenius sp.! Kinda small, so I’m thinking not M. robusta and, thus, probably M. puncticollis (another species new to my collection). I also beat a largish Agrilus sp. that I don’t recognize, a few clerids, two R. meeskei, one Stenosphenus sp., and a couple of leaf beetles. There was also another type of oak there – Arizona white, I believe, which I beat as well but only got one clerid.

It was a fantastic seven days in the field with Arthur, and it was a great pleasure to (in some cases, finally) meet Margarethe, Barbara, Steven, Norm, and Pat. I appreciate the warmth, generosity, and hospitality that all of them displayed to me and look forward to our next encounter, hopefully in the near future. Now, for some light reading during the plane ride home!
