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.

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).

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

We came here to look for Tetraopes skillmani (this is the type locality). We found the host plant (Sarcostemma sp.), but there were no beetles to be seen anywhere. Maybe another location nearby…

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.

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!

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.

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.

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.

Image may contain: sky and nature

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.

We stopped at a spot outside the dunes because it looked pretty green with a number of plants in bloom suggesting recent rain. I saw but did not take Acmaeodera mixta on white flowers of undetermined composite. I did collect a small series of bright red and black clerids on a small blue-green euphorbiaceous plant. Also saw a little horned lizard, who cooperated just enough to get a few snaps!

Vicinity Carrizozo, New Mexico
We stopped at a thick stand of yucca that we’d noted on the way past here earlier in the week, the hope being that we would find Tragidion armatum on the stems. Sadly we did not see any, nor did we see more than just a couple of the pompilid wasps that the beetles mimic. Surely this is a result of the lack of rain in the area, which the hotel clerk confirmed during our earlier check in. Cicadas, on the other hand, were everywhere!

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).

One of the more exciting finds of the trip – a jewel beetle in the genus Gyascutus on Juniperus monosperma (I believe this is G. carolinensis).

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

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

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

Perfect camouflage!

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

Inaugural “One-Shot Wednesday”

On many occasions I have considered making my own contributions to the “Wordless Wednesday” meme. Unfortunately, I find it impossible to post photos of insects and not be allowed to say anything about them. I suppose I could follow Dragonfly Woman‘s “Well-Nigh Wordless Wednesday” example, but that seems like horning in on somebody’s trademark. At last it finally occurred to me a meme that I could use for Wednesday’s that gets around these issues—”One-Shot Wednesday”! Ever photograph an insect and only get off a single shot? Not just one keeper from a series of photos, but only one single photo of the insect, like it or lump it! That’s what I’m talking about here. The subtext, of course, is that there was only that one chance to get everything right—exposure, focus, composition, lighting, etc. Obviously, it’s not my plan to show crappy photos as part of this meme, but rather that occasional instance where I only got off a single shot, and for the most part everything worked pretty well to produce a decent photograph. I would, of course, be more than happy to see this meme take off and spread throughout the insect blogging community, but if it doesn’t and it remains a BitB exclusive then that’s fine also.

Leptoglossus sp. | nr. Corrientes, Argentina

Here is contribution #1 in the meme: a leaf-footed bug (family Coreidae) feeding on flowers of Solidago chilensis  that I photographed a couple of weeks ago near Corrientes, Argentina. According to coreid-specialist Harry Brailovsky (Universidad Nacional Autónoma de México), the expanded hind tibiae place it in the large, mostly New World genus Leptoglossus. Which one, however, is a good question—according to Coreoidea Species File Online, ten species in the genus have been recorded in Argentina, but browsing through available images didn’t immediately turn up a good match for the individual shown in this photo.

I’ve often wondered about the purpose of the leaf-like expansions of the hind tibiae of coreids—which reach truly gargantuan proportions in some tropical species—and their adaptive significance. One can imagine they might serve as a “false target” for potential avian predators, and supporting this idea is the fact that the hind legs seem to break off rather easily when handled. It’s not rare to find individuals in the field missing one or even both hind legs.

To the land of Gauchos

Today I leave for an extended stay in Argentina. Many have asked me if my trip is for work or fun, and my standard response has been, “It’s for work, and it will be fun!” For the next eight weeks, I’ll be helping out with field trials and speaking to farmers (while sampling a few Malbecs as well). Of course I would rather it be an 8-week collecting trip, but I consider myself fortunate even to have an opportunity such as this. I’ll pick up a few insects along the way, but what I really hope to bring back in large quantity is photographs.

It’s a little difficult to predict how reliable and consistent I’ll have internet access or the time to take advantage of it, so postings over the next few weeks may be a little less regular than what has become my usual custom. The trip is also heavily front-loaded with work activities as I get my bearings and spend time getting to know my new colleagues, so I’m not sure when I might have new photos to show here. Not to worry, I have plenty of material that I haven’t yet shown. Until then, I leave you with this photograph I took last November at  in Buenos Aires. These tiny bugs seem to be early-instar leaf-footed bug (family Coreidae) nymphs, their bright red and black coloration and aggregating behavior indicating ample chemical protection against predation.

Brazil Bugs #4 – Mais dos percevejos

I found mais dos percevejos (more of the leaf-footed bugs) on the still-unnamed pink flowering shrub in back of the hotel in Campinas, Brazil.  Not only am I convinced that they truly do belong to the family Coreidae (for the reasons mentioned in the earlier post and below), but also that despite the different color patterns shown by the two individuals in that post that they are indeed a single species.  I also found the above individual, representing an even more heavily melanized version than the two shown previously.  In looking at a large number of individuals on the shrubs (and subsequently encountering them in a different part of Campinas over the weekend), it became clear that there were not just two distinct color forms but a broad range of variability.  I could believe maybe two species occurring together on a common resource, but it seems unlikely that each color variation represents a different species.  Thus, it now seems that there is one highly variable species visiting these flowers.

I had an idea on how to find the name of this species that almost worked.  Rather than Googling “leaf-footed bug” or “Coreidae,” I tried “percevejo” instead, along with Brazil or Brasil.  There were 3 or 4 photographs that showed up in the images search that I recognized instantly as belonging to the same species.  Unfortunately, none of the links where the photos were found gave any information more specific than family (all, however, agreeing with family Coreidae).  I think it’s time to send an email to Harry Brailovsky, a coreid specialist at the Instituto de Biologia (UNAM) in Mexico City.

Photo 1: Canon MP-E 65mm 1-5X macro lens (ISO 100, 1/200 sec, f/13).
Photo 2: Canon 100mm macro lens (ISO 100, 1/200 sec, f/16).
Both photos: Canon 50D, Canon MT-24EX flash w/ oversized DIY concave diffuser. Typical post-processing (levels, color, unsharp mask).

Last minute edit: I just heard back from Harry Brailovsky as I was ready to post (thank you Harry!).  The insect is, indeed, a species of Coreidae, which he identified as a member of the genus Hypselonotus.  I did some searching online to see if I could find any additional clues as the species identity – I found no images that looked right but did find this key to the Hypselonotus of Costa Rica.  The key relies on some ventral characters, and I’m a little uneasy about using it for something from southern Brazil, so I think I’ll just wait until Harry has a chance to look it up when he returns to the museum.

Second update 1/26/11:  Harry has confirmed the species as Hypselonotus interruptus, which was mentioned but not included in the key that I linked to above.  The only online images I have found of this species are at this link. Either Harry is wrong (unlikely), the photos in the link are misidentified (maybe), or the species is enormously variable (perhaps quite likely).

Brazil Bugs #1

ID Challenge #3 update: I knew this would be a hard one, and so far nobody has figured this one out (only one commenter got the right order!).  I’ve released the comments gotten so far so you can see where things stand, and maybe with the additional information (and my pointing out an important clue) it will be enough for one of you to arrive at a full ID.  Further comments are still being moderated until I decide to close the challenge.  Right now the points are there for the taking!


This past Monday I embarked on an extended business trip to Brazil.  “Wow, Brazil!” – you say, and while getting to travel to an exotic tropical locality on my company’s dime definitely rocks, I do have to justify the trip by actually working.  Add that to the time involved with planes, automobiles, and hotel transfers, and there is precious little time for more esoteric activities such as photographing insects.  It is Brazil, however, and summer at that, so whatever time does become available over the next ten days, I’ll be on it!  I’m stationed in Campinas, about 2 hours north of São Paulo, and this evening I had my first opportunity to break out the camera and do a little exploring around the hotel grounds during the waning hours of daylight. I’m not normally one to take short walks just looking for any random insect to photograph, but hey – it’s Brazil!  I also don’t normally like to post photographs of insects without knowing much about them – especially their identity. But hey, it’s Brazil!  I think I’ll be lucky to figure out most things to family, although I might be able to drill down a little further on occasion.  With that prelude, I hope you’ll indulge me these random postings over the next 10 days or so, primarily photographs but perhaps accompanied by a little bit of text.

Coreidae?

At first I thought this was a member of the hemipteran family Pyrrhocoridae (red bugs), as some North American species have similar coloration; however, members of that family apparently lack ocelli, which this insect clearly possesses. This would seem to indicate instead some species of Lygaeidae (seed bugs), but the forewing membrane with numerous veins arising from a transverse basal vein and presence of what appears to be a distinct metathoracic scent gland opening suggest instead some “unleaf-footed” species of leaf-footed bug (Coreidae). Whatever its identity, I would imagine it is quite distasteful, based on what clearly seems to be aposematic coloration and the fact that there were numbers of these bugs hanging out quite conspicuously on these flowers.

Same species?

This individual was differently colored than the others, but otherwise it seemed structurally and behaviorally identical.  Is it merely a highly melanized individual?  Maybe a case of sexual dimorphism, and I only saw this one individual of one of the sexes?  Maybe it truly is a different species – it is Brazil, afterall!

Pseudoplusia includens?

Daylight began to slip away much too soon, and I was about to pack it up when  I noticed some blurs at the flowers.  I realized that moths had begun to visit the flowers in the obscurity of dusk and became determined to photograph one, despite the fact that they never actually landed on the flowers but hovered in front of them instead.  It was quite difficult to even get them framed in the viewfinder, and on those few occasions when I managed to do this it was all but impossible to spend any time trying to focus – I used the lamp on the flash unit to help me see the moth, then just framed and quickly took the shot.  This one actually turned out not too bad – a little bit of blur in the wings but otherwise acceptable enough to let me tentatively identify it as Pseudoplusia includens (soybean looper).  Brazil is well on its way to becoming the world’s largest producer of soybean, and the caterpillars of these moths are enjoying the bounty!

Family Crambidae, possibly Herpetogramma phaeopteralis (ID by Chris Grinter)

I saw one last moth before the final traces of daylight disappeared – I don’t have any idea about its identity, but it’s a pretty picture nonetheless.  It has the generic look of the large family Noctuidae, so that’s what I’m gonna go with until somebody tells me differently.  Edit 1/20/11 – Somebody just told me differently!  According to Chris Grinter, this is a species of Crambidae, possibly Herpetogramma phaeopteralis (tropical sod webworm).  Thanks, Chris!

I don’t know the name of the plant whose flowers these insects were visiting, but the hotel staff has promised to ask their gardener in the morning and let me know – now that’s service!

A “leafless” leaf-footed bug

Merocoris distinctus feeding on flower stem of Coreopsis lanceolata.

This is Merocoris distinctus, a true bug in the family Coreidae whose members are usually recognized by their distinctive flattened hind tibiae (and hence the common name, leaf-footed bugs). This diminutive species, however, lacks that character, instead sporting strangely curved hind tibiae along with club-shaped (incrassate) hind femora. It’s a chunky little species – much smaller than the typical leaf-footed bugs seen across North America, and is most often encountered in grassland habitats where it feeds on herbaceous plants such as goldenrod, Solidago spp. (Slater and Baranowski 1978). This individual was seen probing the upper flower stem of lanceleaf tickseed, Coreopsis lanceolata, during May of last year at Shaw Nature Reserve in east-central Missouri. I’m not sure how well the life history of this species is understood, but I did find one interesting record of twelve individuals feeding gregariously on a dead chicken (Engelhardt 1912)! Apparently, feeding on carrion and other extra-phytophagous foods such as bird droppings and dung is a not uncommon practice among the Coreidae and closely related Alydidae (Adler and Wheeler 1984).

I kind of lucked out with this shot – I’d just gotten my new camera two weeks earlier and can’t say I really knew what I was doing at this point. I had first noticed and photographed the bug sitting on top of the flower but totally blew the exposure due to the flower’s bright yellow color.  My clumsy approach also caused the insect to move under the flower, where I watched it settle down and begin feeding before trying another shot. The dorsal surface of this species is mottled gray and brown, allowing the bug to blend in with most backgrounds. The underside of the body, however, is thickly matted with white hair, providing a very nice contrast with the black background that I stumbled upon achieved in this photo to emphasize the distinctive appearance of this often-overlooked insect.

Photo Details: Canon 50D w/ 100mm macro lens (ISO 100, 1/250 sec, f/14), Canon MT-24EX flash (1/4 ratio), undiffused. Typical post-processing (levels, minor cropping, unsharp mask).

Magodo – giant twig wilter

petascelis-remipes

In previous posts, I have highlighted some of the insects I observed on a trip to South Africa in November-December 1999.  All of the photos I have shown to this point were taken at Borakalalo National Park in North West Province or at the Geelhoutbos farm of Susan Strauss below the Waterberg Range in the formerly Northern, now Limpopo Province.  Both of these locations are deep inside the bushveld, providing ample opportunity to observe an incredible diversity of insect life.  This is not to say that insects, even spectacular ones, cannot be found in more urban areas.  During the weekend between those two mini-expeditions, I stayed with my friend and colleague, Chuck Bellamy, at his home in Pretoria, a beautiful city with lovely architecture, elegant gardens… and some very impressive bugs!  The bug in this photo was found on a tree in a shrubby enclave, and at well over 35 mm in length it is easily the largest leaf-footed bug (order Hemiptera, family Coreidae) that I have ever seen.  Its chunky build, velvety black coloration with thin yellow lines along the sides and down the center of the thorax, and greatly enlarged hind femora quickly led me to a provisional identification of a male Petascelis remipes, or giant twig wilter.  This ID was confirmed by my friend and colleague Harry Brailovsky, an entomologist at UNAM (Universidad Nacional Autónoma de México) and world expert on Coreidae (and who, incidentally, just recently published a review of this Afrotropical genus – Brailovsky 2008).

According to Picker et al. (2002), these insects are found on plants in the genus Combretum.  Like most species in the family, they have scent (“stink”) glands that provide defensive capabilities. Adults are gregarious and bold, walking towards intruders with antennae vibrating when disturbed, and they are apparently capable of squirting their defensive secretions for some distance.  The nymphs are black as well but futher advertise their noxiousness with warning coloration of red spots on a whitish background. Interestingly, and despite their powerful chemical defenses, this species is considered a delicacy in parts of Mozambique where it is known as Magodo.  In a post called Insects for Dinner (in a blog with the eerily similar title, Beating about the Bush), Bart Wursten of Gorongosa National Park in Mozambique describes how local folk burn small patches of the grassland in which these insects are found to smoke them out and catch them.  The Magodo hunters kill the bugs by breaking off the head and removing the scent glands, which releases a very strong almond-like smell.  In doing this, the locals are able to catch considerable quantities of the bugs, which they eat with supper.

Lest you believe such practices are an anomaly, van Huis (2003) has compiled a list of about 250 insect species used as food in sub-Saharan Africa.  Lepidoptera, Orthoptera and Coleoptera represented the bulk (78%) of species eaten, with Isoptera, Hemiptera, Hymenoptera, Diptera and Odonota making up the rest.  Several examples of toxic insects and the traditional methods used to remove the poisons were given.  It was noted that whether or not insects are eaten depends not only on taste and nutritional value, but also on customs and ethnic preferences or prohibitions.  I’m not one to shy away from the thought of eating insects – after all, shrimp are just bugs that live in water, and insects rank far lower in ‘slime factor’ than many other invertebrates (e.g., oysters) that enjoy great popularity in our culture.  I’ve eaten roasted beet armyworm (Spodoptera exigua) pupae and munched on chocolate covered ants, but that’s kid stuff – the armyworms tasted like the soy sauce in which they were roasted, and the ants tasted like, well… chocolate.  I did once eat a softshelled crab (alive!), and I actually hope to one day taste the enormous grub of the giant metallic ceiba borer, Euchroma gigantea, eaten by indigenous cultures in Central and South America.   Still, I think I’d need a lot of faith in my chef’s scent gland removal prowess before I started scarfing Magodo down like popcorn.

What insects have you eaten?
