2022 Oklahoma Insect Collecting Trip iReport

/ Ted C. MacRae / 8 Comments

Welcome to the 11th “Collecting Trip iReport”; this one covering a very short (4 days) trip to northwestern Oklahoma on May 3–7, 2022. My collecting partner for this trip was long-time friend and hymenopterist Mike Arduser. Mike is one of the best natural historians that I know and, like me, has a special love for the often overlooked beauty of western Oklahoma and its fascinating insect fauna. It had been 13 years, however—too long, in my opinion, since our last joint field trip when we sampled the bee (Mike) and beetle (me) fauna at The Nature Conservancy’s Four Canyon Preserve in Ellis Co. Thus, I was happy for the chance to once again spend some time in the field with such a knowledgeable naturalist in an area we that both know and love.

Day 1 – Gloss Mountain State Park (Major Co.)
It took most of the day to get here—Tulsa threw us a couple of obstacles in the form of a construction-mediated wrong turn and a motorcycle engulfed in flames. I’ve been to Gloss Mountain a number of times, but never this early in the season. Skies were sunny (unlike St. Louis when we left this morning), but temps didn’t get much above 60°F and even dropped down into the upper 50s before we finished up at sunset.

Surprisingly, despite the earliness of the season and cool temps, beating was quite productive. Working the low areas around the parking lot, I beat a fair number and diversity of beetles and hemipterans—mostly chrysomelids—but only a single Agrilus sp. off of Prosopis glandulosa.

This must be Oenothera macrocarpa (bigfruit evening primrose, Ozark sundrop, Missouri evening primrose), though it looks very different from populations south of St. Louis.

I knew there were other trees, principally Celtis reticulata (net-veined hackberry) and Sapindus drummondii (soapberry), on top of the mesa and wanted to see if anything was on them. Bingo! Even before reaching the top, I beat a few Agrilus (several spp.) from the Celtis, and up on top I beat quite a few more off the same. There were also additional mesquite trees up top, off which I again beat a single Agrilus sp. along with a few other things, notably a series of ceresine treehoppers. The Sapindus was just starting to leaf out, and I found nothing by beating them other than a single ceresine. A notable find was the pile of larval frass of Plinthocoelium suaveolens (bumelia borer) at the base of a living Sideroxylon lanuginosum (gum bumelia) tree—a sure sign of active infestation by a beetle I have yet to formally record from this place.

On the way back down from the top, we hit the sunset perfectly as it “touched” a peak in the foreground! Despite my success here this evening, Mike saw no bees of interest on the few flowers that were found due to the cold temps and chilling winds, so tomorrow we will continue west hoping for warmer conditions on the western edge of Oklahoma.

The opportunity lasted for only a minute!

Back in town, we searched for an open sit-down restaurant—fruitlessly because of the late hour—and ended up with a mediocre breakfast burrito from a fast food shop I’ve never been to before. The local Buick dealership, however, with its 1950s neon lights shining brightly in the night sky, was a taste of Americana that makes these trips so enjoyable. Life on the road!

Day 2 – Black Mesa State Park (Cimmaron Co.)
Welp! We awoke this morning to cold temps (low 60s), thick fog, and low hanging clouds, and the forecast for the area showed essentially no improvement through at least the day. Our plan had been to hit a spot about an hour southwest before heading back north to Beaver Dunes State Park, but the forecast for both those areas also was cold and wet. It was not until we looked at the forecast for Black Mesa—our last planned stop of the trip and a 4½-hour-drive to the west—that the forecast seemed to be in our favor, so we decided to blast on out there. We figured we would get there at about 2:00 pm and could spend the rest of the day there collecting, camp there tonight, and start heading back east tomorrow (assuming the forecast improved for the areas we missed).

Pronghorn antelope (Antilocapra americana).

Wrong! When we got there, it was not only cloudy and cold, but dry as a bone! Even if it had been sunny with warmer temps, there still would not have been any insect activity to speak of. The leaves of oaks and hackberries in the area were just barely starting to break bud, and the only flowers we saw at the park were a large willow in full bloom—but not a single insect visiting them. Knowing that there was no other place where conditions were better that we could drive to within the next couple of hours and collect for at least a short time, we instead decided to make it a hiking day and hike the High Point Trail at nearby Black Mesa Nature Preserve.

Black Mesa Nature Preserve (Cimmaron Co.)
When we arrived and looked at the signage, we learned that the hike to the oracle at the official high point would be a more than 8-mile hike! Just reaching the top of the mesa itself would be a more than 3-mile-hike, with the high point another mile on top. Not knowing if we had the appetite for such a distance (or time to do it before sunset) and with the wind cold and biting, we started out anyway and gave ourselves permission to turn around at any point if we felt like it.

Nevertheless, we persevered. We checked the cholla (Cylindropuntia imbricata) along the way hoping to see Coenopoeus palmeri (one of the cactus longhorns, which I’m not sure has been recorded from Oklahoma) or at least one of the more widespread Moneilema species, but none were seen (nor really expected). The trail up the side of the mesa was steep and spectacular, and the trail atop the mesa was surreal—especially given the cold winds and low-hanging clouds. Eventually, we made it to the official high point and enjoyed the fun facts carved into each side of the granite obolisk marking the spot.

Coming back down was not much easier than going up, the steepness of the trail jamming my toes into the toe box of my new hiking boots (which performed admirably!), but I did find an insect—a largish black weevil torpidly crawling on the trail. Even on the relatively level lower portion of the trail once we got there was difficult, our legs really starting to feel the miles now. As we hiked the last mile back to the car, the temperature continued to plummet as it started to sprinkle, turning to rain soon after we reached the car and then heavy rain as we headed down the highway back to the east. The irony of the situation—rain coming to a parched landscape just when we are ready to leave—did not escape us. We’ll spend the night in Boise City and hope for a better forecast tomorrow!

Day 3 – Beaver Dunes State Park (Beaver Co.)
Temps were down in the mid-40s when we awoke this morning, but skies were sunny and we were heartened by a promising forecast of continued sun and highs in the low to mid-60s. Our first destination—Beaver Dunes—was a relatively short 2-hour drive further east, and when we arrived sunny skies still prevailed. Unfortunately, temps still hovered in the mid-50s with a biting wind that made using the beating sheet difficult to impossible.

That said, I managed to beat a fair series of Agrilus spp. (probably mostly one species) and a few other beetles off living Celtis reticulata (net-veined hackberry) dotting the roadside along the entrance to the Picnic Area. Under the main group of hackberries I noticed new growth of Cucurbita foetedissima (buffalo gourd) along with last year’s dead stems. I’ve never collected Dorcasta cinerea (a longhorn beetle that utilizes buffalo gourd as a larval host), so I began splitting open the old stems to see if I could find unemerged adults. I didn’t, but what I did note inside the stems was evidence of boring by some insects and, eventually, the tiniest little scolytine bark beetles that I’ve ever seen. They were always found right at the node, usually in pairs (perhaps male and female?), and I ended up collecting a series of about a dozen specimens from two different stems.

Tradescantia occidentalis (prairie spiderwort, western spiderwort).

Also in the main group of hackberries, I noticed a dead branch hanging from the tree, which had fallen but gotten snagged on a lower branch to remain off the ground. The branch was obviously infested and showed a few emergence holes indicative of both buprestids and cerambycids, and when I broke into it I found two unemerged adult Agrilus (different species), which caused me to cut and bundle the branch to being back for rearing. At the entrance, I went to examine the stand of yellow flowers that greeted our arrival, determining them to be Pyrrhopappus pauciflorus (smallflower desert-chicory, Texas false dandelion). While I was on the ground photographing the flowers, I noticed a red and black hister beetle that proved to be Margarinotus bipustulatus—aptly named considering the two red maculations on the elytra. I also noticed a couple of tiger beetle larval burrows in the hard-packed sandy soil and found a long, thin plant stem to “fish” the larvae out. I managed to snag the larva in one of the burrows, which I believe is Tetracha carolina (Carolina metallic tiger beetle) by virtue of the thin white margin around the prothorax and the open habitat in which the larval burrow occurred. If this is true, then it is a second instar because it is slightly smaller than a typical Cicindela sp. third-instar larva.

Afterwards, I went over to the dunes to see if Mike had found anything, but temps were still too cold to see anything flying. He did, however, show me an interesting stand of Penstemon that he’d found and that we determined to be P. fendleri (Fendler’s penstemon). The plants were all on the north side of the dune in apparently protected spots, and I noted that on iNaturalist our observation was the northernmost record for the species (save one suspicious, disjunct Colorado record).

On the way back to the car, I beat a few more beetles off living Celtis reticulata. By now, we’d seen all we needed to see here and decided to head southeast to one of the Brachys barberi locations (that were the reason for this trip in the first place).

5 mi E of Harmon (Ellis Co.)
This

Recently, another coleopterist collected Brachys barberi—more typically a southwestern species—on Quercus harvardii (shinnery oak) at this spot. I’ve not managed to find the species myself yet, and as it was collected on May 3rd last year I hoped the timing would be right. Quercus havardii dominated the landscape at this spot, mostly as thick stands of low-growing shrubs but also as a copse of small trees.

Quercus havardii (shinnery oak, shin oak, Havard oak).

At first, I swept the lowest-growing plants, collecting a variety of mostly chrysomelids and curculionids and even one Agrilus sp., before moving to beating along the sunny edges of the patches of taller shrubs and collecting similar species (but no Agrilus sp.). Just to the north, I noticed a stand of individuals tall enough to be considered trees (presumably a clonal stand) and began beating them. Immediately I began collecting not only the chrysomelids and curculionds that I was collecting before, but also several Agrilus spp. and what must be Agrilaxia texana—a species represented in my cabinet by just two specimens that I collected in northeastern Texas way back in 1984.

I worked nearly the full perimeter of the copse, noticing that most of the beetles were being collected only on the south-facing sunny (and leeward) side. When I was just about ready to call it quits, a much larger black and yellow beetle landed on the sheet. For an instant I thought it was a lycid, but it moved characteristically like a longhorned beetle, and I quickly realized that I had collected Elytroleptus floridanus—a quite rare southeastern U.S. species that I have only seen once before when I reared a single individual from dead oak that I collected in the Missouri bootheel (and representing a new state record). I wasn’t sure the species had ever been recorded from Oklahoma, so I found Gryzmala’s revision of the genus online and saw that it had been previously recorded from the state—but all the way over on the east side near the border of Arkansas. All records from Texas as well are from the eastern side of the state, so today’s capture appears to represent a significant northwestern extension of the species’ known geographic range by about 300 miles!

Sadly, I never saw Brachys barberi, but collecting Elytroleptus floridanus (in Oklahoma!) was a pretty good consolation prize.😊

Day 4 – Prologue (“Good to Go” coffee shop)
We awoke to bright sunny skies, and though a tad chilly it was still warmer than the previous mornings and with a good forecast to boot! It would take about an hour to drive to the day’s collecting spot—the one and only Gloss Mountain State Park (where we visited briefly a few days ago to start the trip), but not until after an unexpected and hilariously bizarre experience at a coffee shop in town called “Good to Go”.

“Good to Go” coffee shop lounge.

Mike was the first to notice the velociraptor in the lounge—saddled up for a ride! Okay, that’s cute. Then he noticed the sign on the outdoor display that read “Stegosaurs roamed the Earth about 5,000 years ago.” At first I thought, okay, they’re a little confused on the timeline, but what they’re trying to say is that dinosaurs lived a long time ago.

“Stegosaurs roamed the Earth about 5,000 years ago.”

Then I noticed a granite plaque in the background that clearly read “The Holy Bible”, and it dawned on me that we had entered a creationist’s den! Had we not already ordered our coffee, I might have surreptitiously tiptoed my long-haired hippy butt out of there before somebody pointed at me and began slowly chanting “Lucifer!”

Apparently this is overwhelming evidence that humans saw living dinosaurs.

Once we were outside the shop, our coffee secured and the need for hushed tones no longer muffling our reactions, we took a quick walk with the dinosaurs to admire their seeming scientific accuracy. I was impressed with the T. rex in particular, it’s body axis realistically horizontal with the tail straight and strong—not the lumbering, upright, tail-dragging version that I learned about as a kid. At least they were accepting some of the current body of scientific evidence on dinosaurs and ignoring only that dealing with their age—or so I thought…

A remarkably scientifically accurate rendition of T. rex with the more recently advocated horizontal posture.

The stegosaur as well appeared to be fairly accurately rendered, its tail also straight and strong and a youngster trailing closely behind, until I noticed something atop the adult—an angel riding it! ‘God’s creatures big and small’, I guess.

Note the angel riding the stegosaur!

The coup de grace was the information plaque behind the stegosaur. Rather than providing information on dinosaurs, I was instead treated to a barrage of hilariously unsupported claims advocating the idea that humans and dinosaurs once lived together. Each “factoid” on the plaque was more bizarre and quotable than the one before. Did you know that the adult stegosaur probably died 4,000 years ago in the Great Flood, but that the baby—happily—likely survived by getting a ride on the Ark with Noah! And all that scientific evidence that pinpoints the Cretaceous extinction to 65 million years ago? Apparently it has merely been fabricated as part of a global conspiracy because scientists just don’t want to agree with the Bible. I just about lost it, however, when I reached “It is uncertain if humans ever rode Dinosaurs, but there is overwhelming evidence that humans saw living dinosaurs.” I mean—What?!

I don’t even know where to begin!

Our unplanned morning entertainment now done, we hit the road for our next—and final—collecting spot for the trip.

Gloss Mountain State Park (Major Co.)
We arrived at about 10 am with a plan to spend the rest of the day there—whether the collecting was good or bad, this would be our final stand. We hiked up to the mesa, stopping at an accessible spot about halfway up to work the trees (me) or set out pan traps (Mike). Beating the Celtis reticulata (net-veined hackberry) yielded a similar assortment of beetles as last time—a couple of Agrilus spp. along with the occasional chrysomelid or curculionoid and a few other beetles, and the same was true with Prosopis glandulosa (mesquite), with the exception that I did not find any Agrilus this time.

Atop the mesa, I decided to do an entire perimeter hike—something I’ve always wanted to do but never actually accomplished. The idea was to beat all of the C. reticulata, P. glandulosa, and Sapindus drummondii (soapberry) that I could find in an effort to “leave no stone unturned” in my quest for beetles. Soon after starting out, I saw a nice Pasimachus elongatus ground beetle running across the mesa top and “forced” it to cooperate for photos by pinning a hind tarsus to the ground with my finger tip (barely visible in the upper left side of the photo). I collected it, as well as another that I saw a short distance away, and then proceeded with the beatings! Beating the C. reticulata was quite productive, with perhaps three Agrilus spp. and numerous other beetles being collected off of nearly every tree that I beat. Beating P. glandulosa also was productive for various beetles, though again no Agrilus were encountered. The biggest surprise came when I started beating S. drummondii, most of which were still in the earliest stages of leafing out. I got nothing from most of the trees (the majority of which were clustered in a small copse near the front of the mesa), but in the back part of the cluster were a couple of trees with noticeably more foliage—beating them yielded perhaps a dozen Agrilus limpiae, a soapberry specialist that I haven’t seen in numbers since 1986 when I collected a series on soapberry in south-central Kansas.

I rarely get anything beating Sideroxylon lanuginosum (gum bumelia), but I beat most of the trees that I saw anyway and collected one cryptocephaline chrysomelid and two curculionoids. A single Eleodes hispilabris (apparently on its last leg) was seen near the north end of the mesa, which I photographed and collected, and on the way back I encountered a small patch of Sphaeralcea coccinea (scarlet globemallow) in bloom, from the flowers of which I collected a few small melyrid-type beetles and a small halictid bee for Mike. Also on the north part of the mesa I saw a young eastern collared lizard (Crotaphytus collaris), who posed just long enough for me to get off a shot before blasting away from my approaching lens.

Throughout the hike atop the mesa I kept my eye out for “new-to-me” plants (of which there are many), finding for the first time Toxicodendron rydbergii (western poison ivy) and blooming individuals of Chaetopappa ericoides (rose heath). Physaria gordonii (Gordon’s bladderpod)—a relative of the federally threatened P. filiformis (Missouri bladderpod)—was blooming abundantly atop the mesa. At this point, Mike and I rejoined and relayed to each other our more notable findings. For Mike’s part, he had seen a couple of cacti that I had missed—Escobaria missouriensis (Missouri foxtail cactus) and Echinocereus reichenbachii perbellus (black lace cactus)—and took me to the spots where he had seen them. While retracing our steps, we also found Gaillardia suavis (pincushion daisy, perfumeballs) and the strikingly beautiful Penstemon cobaea (cobaea beardtongue, prairie beardtongue, foxglove penstemon).

By this time, I had been on the mesa top for five hours, and even though temperatures were mild (mid-70s) I desperately needed food and water. Mike, for his part, had also had a wildly successful day with bees, capturing many at the flowers and many more in the various pan traps (both in top and halfway up the slope). I descended the steep slope with its mixture of metal steps, cut rock, and wooden planks and enjoyed a quick feast of sardines and Triscuits (a decades-long bug-collecting-trip staple) washed down with Gatorade before getting back to work on the mesquite around the parking lot. I was committed to trying to find Agrilus on the plants—a single individual of which I’d beaten from the plants three days earlier, and after beating several plants and seeing none (but collecting a great number of clytrine and cryptocephaline chrysomelids along with other insects) I finally found one! I continued to work the trees and collect primarily chrysomelids, but no more Agrilus were seen. I am hopeful that it will be a southwestern species not currently known from Oklahoma—a situation I have found with several other Prosopis-associated beetles in this part of northwestern Oklahoma.

I hadn’t intended to work any additional Prosopis beyond the road into the parking lot, but there were a few particularly large trees along the front of the park next to the highway rest stop. The first one I beat yielded a very large cryptocephaline that I had not seen on any of the other Prosopis, so I continued beating them and collected a nice series along with a few other clytrines, pachybrachines, and curculionoids. At the furthest point west, I recalled having seen during a previous visit a western diamondback rattlesnake a bit further to the west, so I continued to the spot hoping to see another. No such luck, so I tiptoed through the tall grass back to safety and made my way back to the car to wrap up seven and a half hours of collecting on a spectacular day—sadly, the last of the trip!

Epilogue
This trip was just a warm-up. In just over one week, I will head out again—this time to western Texas and southern Arizona for sure, and maybe elsewhere depending on how things go. At three weeks, it will be the longest collecting trip I’ve done since I went to South Africa in 1999 and Ecuador 10 years before that. I’m also looking forward to meeting up with a number of other coleopterists at various points during the trip—Jason Hansen, Joshua Basham, and Tyler Hedlund in Texas, and Norm Woodley and Steve Lingafelter in Arizona. If there is time, I may stop off at a place or two in northeastern New Mexico and at Black Mesa on the way back. Look for an iReport on that trip sometime in early-mid June!

Missouri Native Plant Society Spring 2022 Field Trip

/ Ted C. MacRae / 8 Comments

For the past few years, I’ve been involved with the Missouri Native Plant Society (MONPS). To this point, however, my involvement has been limited to attending the monthly meetings of the St Louis Chapter—unfortunately, now only via Zoom since the beginning of the pandemic. I hope that soon we can return to in-person meetings (or, even better, a hybrid of the two, which allows person-to-person interaction without excluding participation by those who cannot attend in-person), but one activity that has resumed live are their periodic, multi-day field trips. The Spring 2022 Field Trip, held this past weekend in southwestern Missouri, was my first chance to participate in one of these events, and I looked forward to seeing the remnant prairies, limestone, dolomite, and sandstones glades, and chert woodland that were all on tap while rubbing elbows with some of the state’s best botanists and naturalists—some old friends and others new acquaintances!

Day 1 – Schuette Prairie
I wasn’t able to make it to the actual Day 1, so I left St. Louis early in the morning to meet the group at the first stop of the following day—Schuette Prairie in Polk Co. Named after my friend and former Cuivre River State Park naturalist, Bruce Schuette, this recently acquired limestone/dolomite prairie with a wet swale contains many plants more typical of glades such as Silphium terebinthinaceum (prairie dock), Echinacea paradoxa (yellow coneflower), and Rudbeckia missouriensis (Missouri coneflower). Of course, on this cold, overcast, early-April morning, it was far too early to see any of these highly charismatic plant species (although some of the more astute botanists were about to point them out by their barely emergent foliage, which was easy to find in the recently-burned northern half of the parcel). Abundantly in bloom, however, was the more subdued Erythronium mesochoreum (prairie fawn lily, midland fawnlily, prairie dogtooth violet). Distinguished from the similar E. albidum (white trout lily) that occurs abundantly further east by its narrower, folded, usually unmottled leaves, all but a few of which remained stubbornly closed against the stiff, cold wind.

Precious few other blooms were seen—I recall somebody mentioning they had seen Viola sororia (common violet), and I photographed this little clump of Fragaria virginica (wild strawberry) that will eventually provide food for one of the area’s many box turtles.

Fragaria virginica (wild strawberry).

Speaking of box turtles, I found this completely naked, bleached carapace and at first hoped that it might have been from an ornate box turtle (Terrapene ornata)—limited in Missouri to western prairies and a species I have not yet seen. However, the presence of a midline ridge and its relatively more domed shape suggest it is from a three-toed box turtle (Terrapene carolina triunguis).

Many other carapaces were seen (though none in such good shape), and in fact bones of many types were easy to find in the burned portion of the prairie. This disarticulated skull from what appears to be a young calf (Bos taurus) was perhaps the most impressive bone find, but we did also find a dried skeleton of a smaller individual. Being the lone entomologist of the group, I just had to turn over the carcass and search for beetles and managed to capture a skin beetle (family Trogidae) and one other small unidentified beetle (but, unfortunately, no Necrobia rufipes [red-legged ham beetle]).

Rocky Barrens Conservation Area
Later in the morning, the group caravaned to Rocky Barrens Conservation Area, a 281-acre area in Greene Co. featuring Mississippian limestone glades and site for the federally-endangered Physaria filiformis (Missouri bladder-pod). This plant, in the mustard family, is found only in four counties in southwest Missouri. The plants were readily found, but we were too early to see them in bloom—or anything else, for that matter. For me, however, the glade alone was still interesting, and I couldn’t help but take note of the similarities—and differences—between this limestone example and the dolomite glades south of St. Louis with which I am so much more familiar. Almost immediately, I noted the presence of Sideroxylon lanuginosum (gum bumelia), host for Plinthocoelium suaveolens (bumelia borer)—surely one of North America’s most beautiful longhorned beetles! I didn’t see any frass piles at the base of any of the trees, the presence of which would indicate larval activity, but I’m sure the beetle is here. It would be interesting to come back during the season and look for it. While I didn’t find any signs of the beetle, I couldn’t miss the bright orange-yellow gold-eye lichens (Teloschistes chrysophthalmus) colonizing it’s branches.

Another tree that caught my interest was Celtis tenuifolia (dwarf hackberry). I see these small, gnarly versions of the genus in glades and other xeric habitats, and they always catch my interest because of the diversity of interesting woodboring beetles associated with it. As I looked at the trees, I noticed one small tree in particular that was the perfect stage of dead—branches brittle but bark mostly still intact with a little bit of peeling on the trunk revealing woodboring beetle larval galleries underneath! There were only a few emergence holes present—strong evidence that the tree was still infested and worth bringing back to put in an emergence box to trap the emerging adult beetles. With luck, I’ll be pinning a series of Agrilus ferrisi next winter!

Corry Flatrocks Conservation Area
After lunch at a nearby city park, the group caravaned to Corry Flatrocks Consevation Area in Dade Co.—site of another federally-endangered plant, Mononeuria minima (formerly Geocarpon minima) (tiny-Tim, earth fruit). The sandstone glades at this site are among the largest in the area and, thus, host a large population of the plant. By this time of day, the sun had been out for awhile and the day had warmed considerably, so we hoped to see other flowering plants as well. Among the first that we encountered while walking towards the glade proper was Ranunculus fascicularis (early buttercup), distinguished from other “large-flowered buttercups” by its canescent (grayish due to hairiness) leaves with long and narrow lobes, their tips bluntly pointed or rounded. The dry, gladey habitat also distinguishes the species from the similar R. hispidus (hairy buttercup), which flowers at the same time but prefers moister habitats.

On the glade proper, we quickly encountered tiny little saxifrages in bloom, which turned out to be Micranthes texana (Texas saxifrage), restricted in Missouri to this part of the state (and thus with a high CC value of 9) and distinguished from the more widespread M. virginiensis (early saxifrage) by its small, compact stature. These first individuals we encountered had especially reddish-tinged flowers.

As soon as we reached the more open part of the glade with large expanses Of exposed rock, the group dropped to their hands and knees to find the diminutive plants we were looking for.

The plants were not uncommon, even abundant, in shallow, sand-filled depressions in the rock. Nevertheless, careful observation was still required to see and recognize them. Fortunately, the plants were already in bloom, their tiny styles barely visible to the naked eye within the green, not-much-bigger, petalless flowers. Photographing these plants, and especially those in bloom, proved to be a task almost beyond the capabilities of the smart phones that most in the group were using (me included).

At the margins, white flowering trees were noticed, and moving closer they proved to be Amelanchier arborea (downy serviceberry, common serviceberry)—among the first we have seen open this spring. (I typically see the first blooms of these trees in the final days of March, at least around my home in east-central Missouri.) an even closer looked revealed tiny insects (also among the first insects I have seen active this spring) flying around and crawling about on the flowers. These proved to be parasitic hymenopterans—family ID is still pending, but I suspect they will prove to be a species in one of the many families of “microhymenopterans” that are egg parasitoids. I am not sure whether they were visiting the flowers as pollinators (which behavior I am not aware of) or in hopes of encountering other pollinators which could potentially serve as hosts—a subject with which I will need to follow up.

Near the back end of the glade, we encountered a few more Micranthes texana (Texas saxifrage), these having more typical white flowers in perfect peak bloom.

Also in that part of the glade we found a few scattered individuals of Selenia aurea (golden selenia). While not quite as conservative as M. texana (CC value = 6), it has a similar range in the U.S. and in Missouri is also restricted to a handful of counties in the southwestern part of the state. The plant is known to occur in large colonies (which I have seen at nearby Corry Branch Glade)—its brilliant yellow flowers forming a spectacular display.

To this point, the only insect I had seen besides the microhymenopterans was a skin beetle (family Trogidae), which I found when I kicked over some dried mammal scats. However, on the way back to the cars we finally encountered an insect large enough in size and striking enough in appearance to pique the interest of not just me but the group as a whole—a large caterpillar feeding on the foliage of Penstemon digitalis (smooth beard-tongue). It’s appearance—dark with longitudinal yellow stripes and blue spotting—immediately called to mind one of the tiger moths (formerly Arctiidae, now a subfamily in the Erebidae), specifically the genus Haploa (commonly called haploa moths). A little detective work on BugGuide comparing photos and recorded host plants narrowed the likely choice to H. confusa (confused haploa moth).

Day 2 – Lead Mines Conservation Area
The final day of the MONPS Field Trip featured a morning trip to Lead Mine Conservation Area in Dallas Co. Of particular interest to the group were several parcels within the area designated as Niangua River Hills Natural Area and featuring a diversity of habitats including dolomite glades, chert woodlands, and calcareous wet meadows (fens). Most in the group visited the northern parcel to see the dolomite glades; however, a few of us—primarily from St. Louis and well-familiar with dolomite glades—opted to visit the smaller southern unit of the natural area to see the fen and riparian woodland we needs to pass through to get there. It was a much warmer morning than yesterday, though still chilly starting out, so blooms were sparse as we hiked the woodland trail searching for any hint of color. At one point, someone noticed a shrub a bit off the trail with large, reddish pink flowers—the color seeming a bit unexpected for the situation. Bushwhacking toward it, we realized it was Chaenomeles speciosa (common flowering quince), a common, ornamental non-native plant that rarely—but obviously sometimes—escapes cultivation. While the group looked at the plant, I saw my first insect of the day—Paraulacizes irrorata (speckled sharpshooter), one of our largest and most recognizable leafhoppers, sitting head-down on the stem of a small sapling.

Paraulacizes irrorata (speckled sharpshooter).

Among the first native blooms we saw was Ranunculus hispidus (hairy buttercup). Though similarly “large-flowered” as R. fascicularis (early buttercup), it differs by its sprawling growth habit, differently shaped-leaves, and preference for moist habitats. Buttercups are a favorite flower host for jewel beetles (family Buprestidae) in the genus Acmaeodera, and one species —A. tubulus—is among our earliest-emerging beetles in the spring, so I checked each buttercup flower that I saw hoping to see these little beetles signaling the beginning of insect activity for the season. Sadly, none were seen.

Ranunculus hispidus (hairy buttercup).

At last we reached the fen—a large open area on the toe-slopes of the adjacent hillside where water draining through the underlying strata emerged to the surface to maintain a continually wet environment. The fen here is special, as two species of Cyprepedium (lady’s slipper orchids) are know to occur in the fen (and in fact, all four of the state’s Cyprepedium spp. can be found with Lead Mine Conservation Area). At this early date, the orchids would not be anywhere close to blooming; however, the group looked for evidence of their presence, walking gingerly through the fen so as to avoid inadvertently stepping upon any emergent foliage. No putative clumps were found, but already in my mind I’m thinking a mid-May trip back to the fen might be warranted! Unlike the orchids, Castilleja coccinea (Indian paintbrush) was abundantly evident throughout the fen, with an occasional plant almost ready to burst forth their scarlet blooms. Senescent flower stems of composites, presumably Rudbeckia, were also seen throughout the glade, which, combined with the abundance of Castilleja, created the promise of a stunning early-summer display across the fen.

During our time in the fen, two species of butterflies were seen flitting about the herbaceous vegetation: tiny blue Celastrina ladon (spring azure), and one of the dustywing skippers in the genus Erynnis. The former were impossible to photograph due to their persistent flitting and skittish behavior, and the latter almost were as well. Only when I locked the focus on a preset 2x zoom and fired shots in rapid succession while moving the smartphone ever closer to the subject did I manage this one imperfect but passable photograph of the last one I tried. The genus Erynnis is diverse and notoriously difficult to identify, and my expertise with skippers and butterflies pales compared to my skills with beetles, so the ID will have to remain Erynnis sp. until a more authoritative opinion is offered. [Edit 4/6/22, 11:38 am: According to my lepidopterist friend Phillip Koenig, Erynnis horatius and E. juvenalis both fly in early spring, and they cannot be reliably separated from the dorsal side.  Erynnis juvenalis has one or two dots on the ventral hind wing that E. horatius lacks and only flies in the early spring, while E. horatius can be seen through the summer.  If only I could turn the picture over to see what it looks like on the ventral side!]

Returning through the riparian woodlands after visiting the fen, the day had warmed considerably, and numerous flowers not seen earlier were suddenly in full bloom. These included Erythronium mesochorium (prairie fawn lily midland fawnlily, prairie dogtooth violet)—the same species we saw yesterday so reluctantly in bloom at Schuette Prairie. Most were of the familiar form with unmottled leaves; however, we found one individual with notably mottled leaves that resembled those of E. albidum (white dogtooth violet) (1st photo). Nevertheless, the leaves were still narrower than that species and folded, and the plant was growing a mere 12” from another individual with no trace of mottling (2nd photo).

Claytonia virginca (spring beauty) was also blooming in abundance as we took the trail back. I am always amazed at the variability seen in the flowers of this species—from pure white to vividly pink-striped to pink at the tips. This especially vivid pink individual was about as pink as they come.

Sanguinaria canadensis (bloodroot) also was popping up regularly. We had seen isolated plants sitting the trailsides when we first part through—their flowers tightly folded in stubborn response to the chilly morning temperatures. By early afternoon, however, they were spread wide open as invitation to any of the flying insects that had surely also been awakened by the warmer temperatures of the afternoon. While most were seen as isolated individuals, a particularly idyllic clump captured our attention, almost begging “photograph me!”

With that, we rejoined the main group to recount the days experiences and cement new relationships before heading back towards our respective home areas.

Long Ridge Conservation Area
On the way back home, I decided to check out this conservation area in Franklin Co., which I’ve never visited before. The afternoon had gotten quite warm, so I reasoned that maybe today would be the day when insects start coming out in abundance. I was right! As soon as I pulled into the parking lot, I saw a Prunus mexicana (Mexican plum) in full bloom, and walking up to it I immediately saw an abundance of bees and small beetles all over the flowers. The latter turned out to be Orsodacne atra (a leaf beetle) and Ischnomera ruficollis (rednecked false blister beetles).

Inside the woods along the Blue Trail, there were the usual suspects in bloom—Claytonia virginica (spring beauty), Cardamine concatenata (toothwort), Antennaria parlinii (Parlin’s pussytoes) and Ranunculus hispidus (hairy buttercups).

Eventually I happened upon an Amelanchier arborea (downy serviceberry) in full bloom. There were more O. atra and I. ruficollis on the flowers (though not so many as on the Mexican plum), along with a Mecaphesa sp. crab spider that had caught and was feeding on a male Andrena carlini (Carlin’s mining bee)*.

On the back third of the trail, I found two fallen branches under a Quercus shumardii (Shumard’s oak) that had been pruned by longhorned beetles—presumably Anelaphus villosus. At the end of the trail I found a third such branch of the same species of oak. All three will be placed in an emergence box, and hopefully the culprits will emerge as adults.

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

/ Ted C. MacRae / 2 Comments

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!

Muir Woods National Monument

/ Ted C. MacRae / 8 Comments

This is the best tree-lovers monument that could possibly be found in all the forests of the world. – John Muir

Coastal redwood (Sequoia sempervirens) is the tallest type of tree in the world, with maximum recorded heights approaching 380 feet. This majestic conifer grows only along the Pacific Coast in a narrow strip from Monterey to Oregon. Most of the estimated 2 million acres of original redwood forest are now gone — victims of the saw! One of the small groves that managed to escape this fate due to its relative inaccessibility grows along Redwood Creek and adjacent slopes in what is now Muir Woods National Monument. At heights approaching 260 feet, the redwoods growing here are not the tallest to be found; however, their proximity to San Francisco (just 15 miles from the Golden Gate Bridge) makes them the most heavily viewed examples of this ancient tree. Lynne and I visited Muir Woods a few times in the 90’s after moving to Sacramento — today (3/20) was our first visit since then, and the first ever for Mollie and Madison. In addition to getting to see these marvelous trees once again, we were also treated to a spectacular display of spring wildflowers.

We began our hike on the main paved trail. This is where most visitors confine themselves during a visit to this place, so the picture here documents a rare sight — no people! I apologize for its lack of focus, a consequence of the limitations of my little point-and-shoot camera in the limited amount of light that makes it through these towering trees during late afternoon.

Standing beneath one of these trees and looking up is a lesson in insignificance — the feeling one gets looking straight up the trunk of one of these giants cannot be adequately captured on film (er… microchip).

We quickly tired of the crowds and decided to hike up the Ocean View Trail, which climbs quite steeply up the east side of the valley. This marvelous trail was nearly devoid of people, and we found ourselves winding through thick, dark, cool forest with numerous side ravines. The lower elevations of the trail were dominated by redwood trees and a spectacular array of spring wildflowers. Among the most common was California toothwort (Cardamine  californica [=Dentaria californica]), a member of the mustard family (Brassicaceae). I noticed that the leaves at the base of the plant were broad and oval, while those arising from the flower stalk were slender and lanceolate, often divided into 3 leaflets.

Wake robins (genus Trillium), belonging to the lily family (Liliaceae, sometimes separated into the lily-of-the-valley family, Convallariaceae), are among my favorite wildflowers. We soon noticed Western wake robin (Trillium ovatum) growing commonly in shaded areas along the trail. We were also seeing some purple-flowered wake robins — at first I thought they were a different species, but it soon became apparent that these were older Western wake robin flowers, which change color from white to purple as they age.

A little further up the trail we began encountering small patches of Mountain iris (Iris douglasiana, family Iridaceae). Flower color for this native species ranges from cream-white to lavender, but all of the flowers we saw were of the white variety.

We saw this fat Solomon’s seal (Maianthemum racemosum ssp. amplexicaule [=Smilacina racemosa var. amplexicaulis]) growing in one of the cool, moist, side ravines. This is another member of the Liliaceae (sometimes separated into the Convallariaceae). The large, oval leaves clasping around the distinct, unbranched stem were almost as attractive as the flowers, which apparently give rise to bright scarlet berries in the summer.

In the middle elevations the redwood forest transitioned to drier oak woodland containing a mixture of Douglas-fir (Pseudotsuga menziesii), Pacific madrone (Arbutus menziesii), bigleaf maple (Acer macrophyllum), and tan oak (Lithocarpus densiflorus). Some of the Douglas-firs were enormous.


Indian warrior (Pedicularis densiflora) is a member of the figwort family (Scrophulariaceae, sometimes separated into the Orobanchaceae). This plant, with its striking bright red flowers and finely divided, fern-like leaves, is a facultative parasite on the roots of other plants. Apparently, the genus name refers to an old superstition that sheep could become infested with lice if they ate this plant.


The juncture of the Ocean View Trail with the Lost Trail was closed, so we backtracked down the 1+ miles back to the main paved trail. By now it was fairly late in the afternoon, and the crowds had thinned considerably. Having gotten lots of good views of the giant trees, we began turning our attention downwards to the smaller understory flora. Ferns, of course, are a dominant component of this understory, especially along Redwood Creek. This large specimen may represent Western sword fern (Polystichum munitum) (family Dryopteridaceae), which can apparently be distinguished by small hilt-like projections from the base of the pinnae (leaflets), but I couldn’t get close enough to see for sure.


Abundant on the ground in the valley was redwood sorrell (Oxalis oregana), a member of the family Oxalidaceae. In places this plant covered the ground in thick carpets.


Among the more interesting plants we saw in the valley was California fetid adder’s tongue (Scoliopus bigelovii), yet another member of the Liliaceae or Convallariaceae. I wasn’t sure what this plant was at first, despite its highly distinctive, glossy, mottled foliage. We were too late to see the blooms, which apparently have a fetid odor to attract flies for pollination, but did find the maturing pods on their slender, drooping stems.


Close to the creek’s edge we saw this colony of horsetails (Equisetum sp.), primitive plants in the family Equisetaceae. Members of this group belong to one of the most ancient lineages of vascular plants, dating back to the Devonian period (416-359 million years ago). Their Paleozoic ancestors (Calamitaceae and Archaeocalamitaceae) were giants, reaching heights of 50 ft or more, and were major components of the Carboniferous swamplands. Along with lycopod trees (Lepidodendrales), they were important contributors to coal formation and, like the lycopods, became extinct by the mid-Permian (~270 million years ago). The genus Equisetum represents the only surviving descendants of this lineage. Unlike their extinct progenitors, these small, herbaceous plants rarely exceed 4 ft in height; however, they share many of the same characters such as articulate stems with microphylls arranged in whorls. Recent phylogenetic studies, using both molecular and morphological characters, suggest that horsetails, together with ferns, form a clade representing one of the three major lineages of vascular plants (Pryer et al. 2001).


Nearby we saw a patch of Giant wake robin (Trillium chloropetalum) in flower. These were taller than the California wake robins we saw on the slopes of the Ocean View Trail but similarly characterized by a whorl of 3 leaves and flowers composed of 3 erect petals. Mature flowers darken to a deep red purple, so it seems these plants had just begun flowering. Muir Woods appears to be a good place for observing a diversity of Convallariaceae!


Also along Redwood Creek we found this bigleaf maple (Acer macrophyllum) in full bloom. As its specific epithet suggests, this maple has the largest leaves of any member of the genus — in this example the newly-expanded leaves were distinctly purplish. The picture below shows the greenish-yellow flowers (petals inconspicuous) produced on long, pendulous racemes.


Interpretive signs along the paved main trail pointed out a redwood “family group,” formed by sprouts growing from the base of a larger tree. Eventually, the central “mother” tree died and decayed away, leaving a ring of offspring that mature into an enormous, characteristic circle of trees. This apparently also happens with other types of trees, though on a smaller scale, as demonstrated in this picture of an oak (Quercus sp.) family group.


As the day drew to a close we found ourselves back in the parking lot, where this California icon, a clump of Coast live oak (Quercus agrifolia), was spreading its wide, majestic crown from multiple, twisted trunks and gnarled branches.


Much too soon, it was time to leave this beautiful valley, but before heading back to Sacramento we stopped to take one last look down towards the valley and out to the Pacific Ocean from the Panoramic Highway.
