Oklahoma Collecting Trip iReport

I’m back home after my week-long collecting trip to western Oklahoma, and at the risk of sounding hyperbolous I can only describe it as one of the most successful collecting trips I’ve ever had. Seriously! These kinds of trips don’t happen all that often for a variety of reasons—timing is off, rains didn’t happen, weather was uncooperative, etc. etc. Once in a while, though, everything comes together, and this was one of those times. The trip was also a return to my roots so to speak—I’ve been rather distracted in recent years with tiger beetles, but jewel beetles (family Buprestidae) and, to a lesser extent longhorned beetles (family Cerambycidae), are really the primary focus of my taxonomic studies. It had been several years since I’d had a good “jewel beetle trip,” so that was the focus of this trip. In planning the trip, I recalled seeing jewel beetle workings in several woody plant species in the same area during last September’s trip, and the occurrence of May rains seemed to bode well for my early June timing.

My instincts proved to be justified—in seven days in the field I collected an estimated 1000–1500 specimens representing at least two dozen species of Buprestidae and a dozen or more Cerambycidae. More important than the numbers, I collected a number of species in good series that I have either not or only rarely collected before, and in fact the second beetle that I collected turned out to be a new state record! Of course, I also brought along my full-sized camera and associated gear and photographed many of the species that I collected. I will feature these photos in future posts, but for this post I thought it might be fun to give a high level view of the trip illustrated only with photos taken with my iPhone (which I also carry religiously in the field with me). The iPhone is great for quick snaps of scenery and miscellaneous plants and animals for which I don’t feel like breaking out the big camera, or as a prelude to the big camera for something I’d like to share right away on Facebook. Moreover, there are some types of photos (landscapes and wide-angles) that iPhones actually do quite well (as long as there is sufficient light!).

Gloss Mountains State Park, Major Co., Oklahoma

Atop the main mesa at Gloss Mountains State Park, Major Co., Oklahoma

My first destination was Gloss Mountains State Park (Major Co.), a stunning system of gypsum-capped, red-clay mesas. I’ve already found a number of rare tiger beetles here such as Cylindera celeripes (Swift Tiger Beetle), Amblycheila cylindriformis (Great Plains Giant Tiger Beetle) and Dromochorus pruinina (Frosted Dromo Tiger Beetle), and in the past two falls I’ve found two interesting jewel beetle records: Chrysobothris octocola as a new state record, and Acmaeodera macra as a northern range extension. On this trip, I started out beating the mesquite  (Prosopis glandulosa) and immediately got the longhorned beetle Plionoma suturalis—a new state record! They were super abundant on the mesquite, and I collected several dozen specimens along with numerous C. octocola as well. I then moved over to the red-cedar (Juniperus virginiana), which was showing a high incidence of branch dieback, and collected nice series of several buprestids, including what I believe to be Chrysobothis ignicollis and C. texanus. Up on top of the mesa there are small stands of hackberry (Celtis laevigata) and soapberry (Sapindus saponaria), both of which are very good hosts for Buprestidae. Not much was on the soapberry, but I beat large series of several Buprestidae from the hackberry, including what I believe to be Chrysobothris caddo and—the real prize—Paratyndaris prosopis! My old friend C. celeripes was also out in abundance, so I collected a series to add to my previous vouchers from this site. Back down below, I marveled at a juvenile western diamondback rattlesnake (Crotalus atrox) in the area where I found some more A. cylindriformis larval burrows. Daylight ran out before I could dig them up, and after 11 hours in the field I was exhausted, so I returned the next morning and got one 1st- and two 3rd-instar larvae and went back up on top of the mesa and beat several more P. prosopis from the hackberry.

My second stop was at Alabaster Cavern State Park (Woodward Co.), where C. celeripes was again abundant on the gypsum-clay exposures surrounding an impressive gorge thought to be a collapsed cave complex. I focused on beating hackberry because of the success with buprestids on this plant at Gloss Mountains SP, and although they were not quite as abundant here as at Gloss Mountains I still managed to end up with good series of C. caddo and several species of Agrilus. Because I had spent the morning at Gloss Mountains, I had only a partial day to explore Alabaster Caverns and, still getting used to the weight of the camera bag on my back, decided to leave the big camera in the car. This was a mistake, as I encountered my first ever bullsnake (Pituophis catenifer sayi) and had to settle for iPhone photos of this species—the photo above being the best of the bunch. An approaching storm put an end to my second day after another 10 hours in the field, and I drove an hour to Woodward.

My third day started out at nearby Boiling Springs State Park, a riparian oasis on sandy alluvium alongside the nearby Cimarron River. The woodlands are dominated by hackberry and American elm, and although a few buprestids were beaten from hackberry and honey locust (Gleditisia triacanthos), the numbers and diversity were not enough to hold my interest in the spot. After lunch, I decided to return to Alabaster Caverns SP and explore some other areas I had not had a chance to explore during the previous partial day. It’s a good thing that I did, as I ended up finding a nice population of longhorned cactus beetles in the genus Moneilema associated with prickly pear cactus (Opuntia phaecantha). I collected a nice series of adults and also learned a few lessons in how to photograph these beetles on their viciously protective host plants. The photo above gives a taste of what will come in the photos that I took with the big camera. After eight hours in the field and darkness falling, I drove two hours to Forgan in Beaver Co.

Beaver Dunes State Park, Beaver Co., Oklahoma

Day 4 in the field started out cold and ominous, having stormed heavily during the previous night and with thick clouds still hanging in the sky. I feared the day might be a wash but decided to venture to Beaver Dunes State Park anyway and take my chances (beating can still be productive even in cold weather as long as the foliage is not wet). It’s a good thing that I did, as the buprestids were as numerous as I’ve ever seen them. The park’s central feature is a system of barren sand dunes that are frequented by ORV enthusiasts and surrounded by hackberry woodlands. The park also has a reservoir and campground, around which are growing a number of cottonwoods (Populus deltoides).

These hackberrys and cottonwoods proved to be extraordinarily productive. On the former I collected large series of several species of Chrysobothris and Agrilus, and while I collected fewer Buprestidae on the latter, these included Agrilus quadriguttatus and Poecilonota cyanipes! The latter species I had never collected until last year (from Cerceris fumipennis wasps), and beating the lower branches of the declining cottonwoods produced a series of about a dozen specimens. I also got one specimen on black willow (Salix nigra), along with a few Chrysobothris sp. and what I take to be Agrilus politus. Also in a low branch of one of the cottonwoods was a bird’s nest with a single egg that, according to Facebook comments, either represents the American Robin or a Gray Catbird. (I returned the next day and saw two eggs in the same nest.)

As the day drew to a close, I found two interesting longhorned beetle species at the edge of the dunes: one large, powdery gray Tetraopes sp. on milkweed (Asclepias sp.), and huge numbers of Batyle ignicollis evidently perched on the yellow spiked inflorescence of an as yet undetermined plant. I have seen this species on many occasions, but always in low numbers, yet here were literally hundreds of individuals on the plants, all having assumed a characteristic pose on the inflorescence suggesting that they had bedded down for the night. I only spent eight hours in the field on this day because of the late start, and as darkness approached I began the two-hour drive to Boise City.

Black Mesa landscape

The final two days in the field were supposed to be spent exploring the area around Black Mesa in the extreme northwest corner of Oklahoma, and another hour of driving was needed to get to the area from Boise City. I first went to Black Mesa State Park, and while the landscape was stunning (see above) the area was extremely dry. I feared the collecting would not be at all productive in this area but wanted to give the area a good effort before making a call. As I approached the entrance to the park, I saw a jeep parked by the side of the road with a license plate that read “Schinia,” which I recognized as a genus of noctuid moths that are very popular with collectors. I pulled over and talked to the driver, who was indeed a lepidopterist from Denver and had just arrived himself. We talked and exchanged contact information, and learning of my interest in beetles he directed me to a small stand of Gambel oak (Quercus gambelii) and one-seed juniper (Juniperus monosperma) on a sculpted sandstone escarpment not far from the park. I found the spot, and although I beat three Chrysobothris sp. from the first juniper tree that I whacked, another hour of beating produced only one more beetle from the juniper and nothing from the oak. I returned to the spot where we had met and encountered him again on his way out! We stopped and chatted again and found a few specimens of what I take to be Typocerus confluens on the yellow asters, but by then I was having my doubts about staying in the area. I told him I was going to check out a ravine in the park and then decide.

The petrified forest ended up being the only interesting thing I found in the ravine—the area was so dry that I think even the real trees were almost petrified! At any rate, it was clear that I was not going to have much success in this area. I looked at my watch, knowing that it would take three hours to drive back to Beaver Dunes, and estimated that if I left now I could get in about three hours of collecting at Beaver Dunes where I’d had so much success the previous day. Thus, I did what I rarely do on a collecting trip—drive during the afternoon!

Beaver Dune

I arrived back at Beaver Dunes with several hours of daylight still remaining, so I decided to take a look around the main dunes before heading towards the woody plants. I’ve actually visited Beaver Dunes previously, on the tail end of a fall tiger beetle trip in 2011. At that time I had seen only the rather common and widespread species Cicindela formosa (Big Sand Tiger Beetle) and C. scutellaris (Festive Tiger Beetle), but I thought there could still be a chance to see the much less common C. lengi (Blowout Tiger Beetle). Early June, however, is a little late to see the spring tigers, and in fact I saw only a single C. formosa. Nevertheless, I find dune habitats irresistible—alien habitats occupied by strange plants and animals, and I spent a bit of time exploring the main dune before heading back towards where I had collected so many Buprestidae the previous day.

Low water levels in the reservoir at Beaver Dunes are a result of three years of drought.

Western Oklahoma, like many parts of the central U.S., has suffered rather severe drought conditions for the past several years. This was evident not only in the large amount of branch dieback seen in the woody vegetation of the area (and probably a contributor to my success at collecting Buprestidae) but also the very low water level in the park reservoir. In the photo above the small cottonwood saplings in the foreground and large cottonwood trees in the left background indicate the normal water level. Cottonwoods, of course, like to keep their feet wet, and the trees around this reservoir—left high and dry by the drought—have responded with major branch dieback and lots of subsequent adventitious sprouting at the bases of the main branches. It was from this adventitious growth that I had beaten most of the Poecilonota cyanipes that I collected the previous day, so I repeated the cottonwood circuit in the hopes of collecting more. Not only did I collect more, but I collected twice as many as the previous day, so I ended up with a very nice series of more than two dozen individuals of the species from the two days collecting. I also did a little more beating of the hackberry trees which had produced well the previous day and collected several more Chrysobothris caddoC. purpureovittata, and Agrilus spp. such as A. leconteiA. paracelti, and perhaps others. When I arrived I was unsure whether I would stay here the following day, but eventually I decided I had sampled the area about as well as I could and that I would go back to the Gloss Mountains for my last day in Oklahoma. Thus, as the day began to wane I began hiking back to the car and spent the next two hours driving back to Woodward to spend the night.

Arriving at the Gloss Mountains the next morning was like coming home! I’ve spent so much time at this place and found so many great insects, yet every time I come here I find something new. Today, however, my goals were more modest—I wanted to improve on my series of Paratyndaris prosopis and Chrysobothris texanus, so I focused most of my time beating the hackberry and juniper on top of the mesa and continued beating the juniper down below as well. Success! I collected four more Paratyndaris off of the hackberry, but the C. texanus were far more abundant on this day than they were earlier in the week—I probably got another two dozen individuals of this species. Of course, I also got distracted taking photographs of a number of things, so the day went far more quickly than I realized. I wanted to leave around 6 pm and get in about three hours of driving so that I would have time to make it into Missouri the next morning and have a nice chunk of time to collect before finishing the drive and arriving home on Saturday night. It was actually closer to 7:30 pm before I hit the road, the reason for the delay being the subject of a future post (I will say that BioQuip’s extendable net handle comes in handy for much more than collecting tiger beetles!).

For my last day of collecting, I decided to stop by at one of my favorite spots in the White River Hills of extreme southwestern Missouri—Hercules Glades Wilderness in the Mark Twain National Forest. I’ve been to this place a number of times over the years, but in recent years my visits have usually been late in the season to look for the always thrilling to see Cicindelidia obsoleta vulturina (Prairie Tiger Beetle). It had actually been about 25 years since I’d visited these glades during the spring, and because of the success I’d had collecting in Oklahoma I was really optimistic that I would find the same here. Sadly (and inexplicably), insect activity was very low, and it didn’t take long for this to become apparent as branch after branch that I beat along the trail through the dry-mesic forest down to Long Creek yielded nothing. By the time I got to the creek I still had not collected a single beetle. A consolation prize was found along the creek, as beating the ninebark (Physocarpos opulifolius) produced a few specimens of the pretty little Dicerca pugionata, and a couple more consolation prizes were found further up the trail approaching the main glade when I saw a Cylindera unipunctata (One-spotted Tiger Beetle) run across the trail and then beat a single Agrilus fuscipennis from a small persimmon (Diospyros virginiana) tree at the edge of the glades. It had been about 25 years since I last collected the latter species, so I was very happy to see it, but no more were seen despite beating every persimmon tree that I saw during the rest of the day. At the end of the day, I had hiked seven miles and collected only six beetles—a rather inauspicious ending to what was otherwise a wonderfully successful trip.

Arriving back at the car at the end of the day on the last day of an extended collecting trip is always a little depressing—despite the vagaries of travel, cheap hotel beds, meals on the go, and general exhaustion, I’m never happier than I am when I am in the field. Still, the success that I’d had during this trip did much to ease my depression, and arriving home late that night and seeing my girls again (who waited up for me!) finished off any remaining depression.

My favorite of Missouri’s milkweeds

Milkweeds of the genus Asclepias are among my favorite plants, although I’m not fully sure why that is the case. Sure, their blooms are conspicuous and colorful, but so are those of many other plants. Perhaps one reason is their status as hosts for milkweed beetles (genus Tetraopes, family Cerambycidae). Four species of these beetles occur in Missouri, including the rare T. texanus. Another reason might be their diversity—in Missouri alone there are 16 different species, ranging from the ubiquitous common milkweed (A. syriaca) to the federally endangered Mead’s milkweed (A. meadii). The latter is one of six milkweed species occurring in Missouri that I have not yet seen, so I suppose I should withhold judgement until I’ve succeeding in finding all 16 species. Nevertheless, I would have to say that clasping milkweed (A. amplexicaulis) has to be my favorite of Missouri’s milkweeds.

Clasping milkweed (Asclepias amplexicaulis) | Sand Prairie Conservation Area, Scott Co., Missouri

Clasping milkweed (also known as sand milkweed—not to be confused with A. arenaria occurring further west in the Great Plains) is said to occur sporadically throughout Missouri in prairies, glades, rocky open woods, roadsides, and railroads. However, I have seen this species only a few times—all in dry sand habitats in the southeastern Mississippi Alluvial Plain (or, the “bootheel” as we say here in Missouruh). Until a few  years ago the only time I had ever seen this plant was many years in an eroded sandy opening on Crowley’s Ridge (an elevated ridge of alluvium and loess deposited during the last glacial maximum). Those plants were not in flower, but their was no mistaking their identity due to their erect stems and broad, cordate-clasping, tomentulose leaves with wavy margins. I would see this plant again a few years ago during my first visit to Sand Prairie Conservation Area, and although I would see it again on many subsequent visits, at no time did I succeed in seeing the blooms.

This species is characterized by broad, clasping, tomentulose leaves with wavy margins.

Finally, last year, I returned to Sand Prairie during late April (a weather-delayed installment of my Annual-Birthday-First-Bug-Collecting-Trip-of-the-Year). I had actually gone there to photograph Missouri’s unique intergrade population of the Festive Tiger Beetle (Cicindela scutellaris), but the weather was cool and the beetles apparently had decided to remain in their burrows. A bad day of collecting, however, is still better than a good day of just about anything else—perhaps because there are almost always consolation prizes, and my consolation prize on this day was my first sight of clasping milkweed plants in full bloom.

I may not be exactly sure why I like milkweeds so much, but I think I now know why I like clasping milkweed above all others. The softly colored green and pink blossoms are exquisite, to be sure, but more importantly the species is firmly linked in my mind to one of my favorite Missouri habitats. I imagine that clasping milkweed might be an attractive, if somewhat gangly, addition to a native wildflower garden. However, I’m not sure I would enjoy cultivated plants in my garden as much as I do seeing wild plants in one of Missouri’s rarest and most endangered natural communities.

Backyard gems

I’ve been fortunate to have the chance to travel far and wide in my searches for insects—from the Gypsum Hills of the Great Plains and Sky Islands of the desert southwest to the subtropical riparian woodlands of the Lower Rio Grande Valley, tropical thorn forests of southern Mexico and veld of southern Africa. No matter how far I travel, however, I’m always happy to return to the Missouri Ozarks. It is here where I cut my entomological teeth so many years ago, and though I’ve now scrabbled around these ancient hills for more than three decades it continues to satisfy my thirst for natural history. Though not nearly as expansive as the Great Plains, there are nevertheless innumerable nooks and crannies nestled in the Ozarks, and I find myself constantly torn between looking for new spots (it would take several lifetimes to find them all) and going back to old favorites. Living in the northeastern “foothills” in the outskirts of St. Louis provides an ideal vantage for exploration; however, sometimes I am truly amazed at the natural history gems that can be found within a stone’s throw from my house. Some examples I’ve featured previously include Shaw Nature Reserve, home to a hotspot of the one-spotted tiger beetle, Castlewood State Park, where I found a gorgeously reddish population of the eastern big sand tiger beetle, and Victoria Glades Natural Area, site of the very first new species (and perhaps also the most beautiful) that I ever collected.

Englemann Woods Natural Area | Franklin Co., Missouri

Today I found another such area—Englemann Woods Natural Area, and at only 5 miles from my doorstep it is the closest natural gem that I have yet encountered. One of the last old-growth forests in the state, its deep loess deposits on dolomite bedrock overlooking the Missouri River valley support rich, mesic forests on the moister north and east facing slopes and dry-mesic forests on the drier west-facing slopes dissected by rich, wet-mesic forests with their hundreds-of-years-old trees. A remarkable forest of white oak, ash, basswood and maple in an area dominated by monotonous second-growth oak/hickory forests.

Englemann Woods Natural Area

Steep north-facing slopes border the Missouri River valley.

It is not, however, the 200-year-old trees that will bring me back to this spot, but rather the understory on the north and east-facing slopes. Here occur some of the richest stands of eastern hornbean (Ostrya virginiana) that I have ever seen. This diminutive forest understory inhabitant is not particularly rare in Missouri, but as it prefers rather moist upland situations it is not commonly encountered in the dry-mesic forests that dominate much of the Ozarks. Stands of this tree, a member of the birch family (Betulaceae) are easy to spot in winter due to their habit of holding onto their dried canopy of tawny-brown leaves (see photo below).

Englemann Woods Natural Area

Rich stands of eastern hornbeam (Ostrya virginiana) dominate the north- and east-slope understory.

Why am I so interested in this plant? It is the primary host of the jewel beetle species Agrilus champlaini. Unlike most other members of the genus, this species breeds in living trees rather than dead wood, their larvae creating characteristic swellings (galls, if you will) on the twigs and stems as they spiral around under the bark feeding on the cambium tissues before entering the wood to pupate and emerge as adults in spring. This species is known in Missouri from just two specimens, both collected by me way back in the 1980s as they emerged from galls that I had collected during the winter at two locations much further away from St. Louis. The presence of this rich stand of hornbeam just 5 miles from my home gives me the opportunity to not only search the area more thoroughly to look for the presence of galls from which I might rear additional specimens, but also to look for adults on their hosts during spring and (possibly, hopefully) succeed in photographing them alive.

Englemann Woods Natural Area

Inside the “hornbeam forest.”

Another “draw” for me is the restoration work that has begun on some of the west-facing slopes in the areas. Pre-settlement Missouri was a far less wooded place than it is today, as evidenced by the richly descriptive writings penned by Henry Schoolcraft during his horseback journey through the Ozarks in the early 1800′s. At the interface between the great deciduous forests to the east and the expansive grasslands to the west, the forests of Missouri were historically a shifting mosaic of savanna and woodland mediated by fire. Relatively drier west-facing slopes were more prone to the occurrence of these fires, resulting in open woodlands with more diverse herbaceous and shrub layers. At the far extreme these habitats are most properly called “xeric dolomite/limestone prairie” but nearly universally referred to by Missourians as “glades”—islands of prairie in a sea of forest! I have sampled glades extensively in Missouri over the years, and they are perhaps my favorite of all Missouri habitats. However, it is not future glades or savannas that have me excited about Englemann Woods but rather the availability of freshly dead wood for jewel beetles and longhorned beetles resulting from the selective logging that has taken place as a first step towards restoration of such habitats on these west-slopes. The downed trees on these slopes and subsequent mortality of some still standing trees that is likely to result from the sudden exposure of their shade adapted trunks to full sun are likely to serve as a sink for these beetles for several years to come. I will want to use all the tools at my disposal for sampling them while I have this opportunity—beating, attraction to ultraviolet lights, and fermenting bait traps being the primary ones. It looks like I’d better stock up on molasses and cheap beer!

Englemann Woods Natural Area

Restoration efforts on the west-facing slopes begins with selective logging.

Eastern red-cedar (Juniperus virginiana) is native to Missouri, but in our time it has become a major, invasive pest tree. The suppression of fire that came with settlement also freed this tree from a major constraining influence on its establishment in various habitats around the state, primarily dolomite/limestone glades. Nowadays most former glade habitats, unless actively managed to prevent it, have become choked with stands of this tree, resulting in shading out of the sun-loving plants that historically occurred much more commonly in the state. Untold dollars are spent each year by landscape managers on mechanical removal and controlled burns to remove red-cedar and prevent its reestablishment in these habitats. There is one habitat in Missouri, however, in which eastern red-cedar has reigned supreme for centuries or possibly millenia—dolomite/limestone bluff faces.

Juniperus virginiana

Craggly, old Eastern red-cedars (Juniperus virginiana) cling tenaciously to the towering dolomite bluffs.

With little more than a crack in the rock to serve as a toehold, red-cedars thrive where no other tree can, growing slowly, their gnarled trunks contorted and branches twisted by exposure to sun and wind and chronic lack of moisture. Some of the oldest trees in Missouri are red-cedars living on bluffs, with the oldest example reported coming from Missouri at an incredible 750–800 years old. There is something awe-inspiring about seeing a living organism that existed in my home state before there were roads and cars and guns. These ancient trees are now an easy drive from my house (though a rather strenuous 300-ft bushwhacking ascent to reach the bluff tops)—they seem ironically vulnerable now after having endured for so long against the forces of nature. For me, they will serve as a spiritual draw—a reason to return to this place again regardless of what success I might have at finding insects in the coming months.

Friday Flower: Phacelia purshii

Phacelia purshii (Miami mist) | Sam A. Baker State Park, Wayne Co., Missouri

It’s been rather a long time since I’ve featured a botanical subject here, so it seems a good time to resurrect my “Friday Flower” meme with this delightful little wildflower seen on my birthday field trip a few weeks ago. Phacelia purshii (family Hydrophyllaceae), also known as Miami mist, is one of only four species in this rather large genus (159 species in North America according to the USDA Plants Database) found in Missouri. Though the flowers are small, their deeply fringed petals are quite striking. The late Dan Tenaglia¹ notes at his Missouriplants.com website that the species is limited in Missouri to the extreme eastern portions of the state—the plant shown here was one of several I saw in rich, bottomland forest along Big Creek at Sam A. Baker State Park in Missouri’s southeastern Ozark Highlands.

¹ Dan Tenaglia was not only an expert botanist but a enthusiastic cyclist. He died in February 2007 after being struck by a car while riding his bicycle. Dan’s wife has kept Missouriplants.com up and running since then in honor of his passion for plants. You can help support its maintenance by making a donation to the “Dan Tenaglia Foundation”: 1416 Victoria Avenue, Opelika, Alabama 36801.

This particular woods is one of the richest I’ve seen in the state, and in the past two years I’ve featured a number of interesting plants (Phlox bifida and Tradescantia longipes), invertebrates (Drosphila sp., Magicicada sp.Calosoma scrutator, Pleuroloma flavipes, Graphisurus trianguliferG. fasciatus, Arrhenodes minutus, Neoclytus scutellaris, Corydalus cornutus and Panorpus helena) and even snakes (Crotalus horridus and Agkistrodon contortrix phaeogaster) from there. This year marks the third consecutive birthday that I’ve visited these woods, and since I’ve found something I’ve never seen before each time (hint: just wait till you see what I still have coming from there!), I have a feeling the trend will continue next year as well.

Hover fly on mallow flower

I’ve mentioned before my reluctance to take random “bug on a flower” photos, but the colors of this hover fly (family Syrphidae) and the mallow flower (Malvaceae, possibly Abutilon pauciflorum) on which it was sitting were enough to capture my interest—a rare offering from this blog to dipterophiles. Even though I’m a beetle man, I’ve had reasonably good success identifying the varied insects across several orders and families that I’ve photographed at the Reserve. This one, however, has me a little stumped. I searched the syrphid gallery at Diptera.com but didn’t find a good match, the most similar being the Old World species Episyrphus balteatus. My best guess is something in the tribe Syrphini. Morgan? Keith? Phoridae?

Friday Flower – Spring Coralroot Orchid

As flowers go, I have a passion for orchids.  Despite comprising perhaps the largest family of flowering plants on earth, most people think of orchids as rare, epiphytic plants restricted to the lush, hyper-diverse, tropical rain forests of South America and southeast Asia.  In reality, terrestrial orchids abound in the temperate regions of the Northern Hemisphere, with more than 200 species occurring in the United States and Canada.  Some, such as the lady slippers (genus Cypripedium),  have blossoms as magnificent as their tropical counterparts, while others are less conspicuous and easy to overlook; however, all share the hallmark that unites the family—a modified petal forming a conspicuous lower lip¹

¹ Interestingly, the lip is actually derived from the uppermost petal, but in most species the flower twists during development so that the lip is oriented at the bottom.

Missouri is home to 34 species of orchids (one introduced, and another discovered in Missouri for the first time just a couple years ago).  None of them are truly common like Rudbeckia or Coreopsis, although some are far more common than is realized.  I’ve featured a few of these previously, including Spiranthes magnicamporum (Great Plains Ladies’-tresses), Platanthera lacera (green fringed orchid), Aplectrum hymenale (Adam and Eve orchid), and Goodyera pubescens (rattlesnake plantain orchid).  I’ve traveled to the far corners of the state to see them, but for today’s featured species—Corallorhiza wisteriana (spring coralroot)—I had to travel no further than my front yard.


I’m sure my neighbors hate my front yard. I don’t use fertilizers or herbicides, and I’m unconcerned about the moss that grows amongst the thin stands of mixed grasses under the tall native oaks that shade much of the yard. My neighbor down the street especially probably shakes his head as he walks his dog past my yard every day, frustrated that I don’t share his passion for the lush, thick, über-green bluegrass monoculture that he has achieved (and must pay somebody to cut at least once a week). Spring must be especially frustrating for him, as I don’t even cut the grass until late May, giving the lawn an especially ragged, unkempt appearance. However, whatever my yard lacks in graminaceous greatness, it more than makes up for in its diversity of woodland natives—spring beauty, toothwort, trout lily, violets, coral bells… and spring coralroot. I have several colonies growing at different spots in the yard, all marked with surveyor’s flags to prevent accidental trampling until their bloom period ends and I can (begrudgingly) begin mowing the grass (no more than once a month, if I can get away with it). I’ve enjoyed these coralroot colonies every spring since I’ve lived here, but this spring was the first that I took the opportunity to photograph their blooms.

Of the three Corallorhiza species that can be found in Missouri, C. wisteriana is the most common, occurring in rich or rocky acidic soils of low wooded valleys, ravine bottoms, along streams and on ridges and slopes of open woods (Summers 1981).  My yard qualifies as the latter, occurring on a limestone ridge in mesic upland forest made only slightly more open by the late 1980s construction of the neighborhood and its minimal disturbance limited to the roads, driveways, home footprints and a small amount of associated lawn.  It is distinguished in Missouri from C. odontorhiza (Autumn coralroot) by its spring flowering period and larger flowers with notched or lobed lip, and from the rare C. trifida (known from only a few Missouri counties) by the purple or brownish stems and spotted lip.


As suggested by the unusual coloration, Corallorhiza species are largely (though not completely) lacking in chlorophyll, and as a result are mostly unable to photosynthesize their own food. Instead, the bulbous rhizomes remain hidden within the soil for much of the year, forming symbiotic relationships with soil fungi and flowering only when conditions are favorable (Luer 1975). The past several springs have been wet here, and accordingly I’ve been rewarded with the wonderful sight of these exquisite tiny blossoms.

I can’t say that I’m entirely happy with these photographs, as I found it difficult to get the entire blossom in focus—when the petals were in focus the lip was not, and vice versa, even in straight lateral profile.  Nevertheless, they still show the delicate structure of the lip, with its scalloped edge and crystalline-appearing surface.  The blooms are fading now—soon there will be no above-ground evidence of their existence, and my neighbor and wife will likely gang up on me to finally power up the lawn mower.

Friday Flower – Hedychium coccineum

Distrito Joaquim Igidio is one of four “districts” surrounding Campinas, Brazil.  It is the most remote of the four, with farmsteads dating back more than a century interspersed amongst some of the most significant tracts of Atlantic forest still remaining in the area.  Many of the farmsteads have recently been converted to bars and restaurants featuring live music, making the area a popular weekend getaway for Campineros.  I joined my colleague and some of his friends on a visit to one of these—Bar do Cachoeira—over the weekend during my visit this past January.  After a sumputuous lunch of Brazilian cuisine (including tohesmo torresmo—my new favorite dish) and cerveja, I walked the grounds to look for insects to photograph.  Despite only having an hour or so to look around, the two species of treehoppers I found and photographed made it a successful little venture.  Coming back to rejoin my friends, I saw a few plants with these marvelously bizarre inflorescenses growing alongside a forested stream running through the grounds.  I could tell they were some type of monocot, but beyond that I had no idea.  Something inside me suspected, however, that this was likely not a native species—it just had that introduced, tropical ornamental look to it.  My suspicions were confirmed when I showed the photos to Dr. George Yatskievych, Curator at the Missouri Botanical Garden and Director of the Flora of Missouri Project.  George identified the plant as Hedychium in the Zingiberaceae (ginger family), likely one of the cultivars of Hedychium coccineum.  He added:

This species is native to tropical Asia, but is commonly cultivated in warm regions of the world. A number of cultivars and hybrids involving related species are sold, so it’s hard to be sure which one you photographed.  The most common cultivar seems to be cv. ‘Tara’ and that’s a possibility for your plant.

Known by a number of common names (red gingerlilly, orange gingerlily, scarlet gingerlily, orange bottlebrush ginger, etc.), H. coccineum hails from the eastern Himalyas, where it grows along forest edges and in mountain grasslands.  This herbaceous perennial can reach one to two metres in height and, in some places, has become somewhat invasive.  The existence of rhizomes and bulbs can make control particularly difficult.

An interesting feature of the plant is the long, exserted stamens and stigmas of the flowers.  This feature is suggestive of an interesting pollination mechanism that relies on pollen attachment to the wings rather than the main body of its moth and butterfly pollinators. Pollen transfer is effected as the lepidopterans move from flower to flower seeking nectar, brushing their wings against the floral parts in the process and thus pollinating the flowers (Zomlefer 1994).

BitB Top 10 of 2010

Welcome to the 3rd Annual BitB Top 10, where I pick my 10 (more or less) favorite photographs of the year.  My goal for 2010 was to continue the progress that I began the previous year in my quest to become a bona fide insect macrophotographer.  I’m not in the big leagues yet, but I have gotten more comfortable with using my equipment for in situ field photographs and am gaining a better understanding of lighting and the use of flash.  I also began experimenting with different lighting techniques (e.g. white box) and diffusers and am putting more effort into post-processing techniques to enhance the final appearance of my photographs.  I invite you to judge for yourself how successful I’ve been toward those goals by comparing the following selections with those from 2009 and 2008 - constructive feedback is always welcome:


Best Tiger Beetle

Cicindela denverensis - green claybank tiger beetle

From ID Challenge #1 (posted December 23).  With numerous species photographed during the year and several of these dramatic “face on” shots, this was a hard choice.  I chose this one because of the metallic colors, good focus throughout the face, and evenly blurred “halo” of hair in a relatively uncluttered background.


Best Jewel Beetle

Buprestis rufipes - red-legged buprestis

From Special Delivery (posted July 13).  I didn’t have that many jewel beetles photos to choose from, but this one would have risen to the top no matter how many others I had.  The use of a white box shows off the brilliant (and difficult-to-photograph) metallic colors well, and I like the animated look of the slightly cocked head.


Best Longhorned Beetle

Desmocerus palliatus - elderberry borer

From Desmocerus palliatus – elderberry borer (posted November 18).  I like the mix of colors in this photograph, and even though it’s a straight dorsal view from the top, the partial dark background adds depth to the photo to prevent it from looking “flat.”


Best “Other” Beetle

Enoclerus ichneumoneus - orange-banded checkered beetle

From Orange-banded checkered beetle (posted April 22).  The even gray background compliments the colors of the beetle and highlights its fuzziness.  It was achieved entirely by accident - the trunk of the large, downed hickory tree on which I found this beetle happened to be a couple of feet behind the twig on which it was resting.


Best Non-Beetle Insect

Euhagenia nebraskae - a clearwing moth

From Euhagena nebraskae… again (posted October 21).  I photographed this species once before, but those photos failed to capture the boldness of color and detail of the scales that can be seen in this photo.


Best “Posed” Insect

Lucanus elaphus - giant stag beetle

From North America’s largest stag beetle (posted December 30).  I’ve just started experimenting with photographing posed, preserved specimens, and in fact this male giant stag beetle represents only my second attempt.  It’s hard to imagine, however, a more perfect subject than this impressively stunning species.


Best Non-Insect Arthropod

Scolopendra heros - giant desert centipede

From North America’s largest centipede (posted September 7).  Centipedes are notoriously difficult to photograph due to their elongate, narrow form and highly active manner.  The use of a glass bowl and white box allowed me to capture this nicely composed image of North America’s most spectacular centipede species.


Best Wildflower

Hamamelis vernalis - Ozark witch hazel

From Friday Flower – Ozark Witch Hazel (posted March 26).  The bizarre form and striking contrast of colors with the dark background make this my favorite wildflower photograph for the year.


Best Non-Arthropod

Terrapene carolina triunguis - three-toed box turtle

From Eye of the Turtle (posted December 10).  I had a hard time deciding on this category, but the striking red eye in an otherwise elegantly simple photograph won me over.  It was also one of two BitB posts featured this past year on Freshly Pressed.


Best “Super Macro”

Phidippus apacheanus - a jumping spider

From Jeepers Creepers, where’d ya get those multilayered retinae? (posted October 5).  I’m not anywhere close to Thomas Shahan (yet!), but this super close-up of the diminutive and delightfully colored Phidippus apacheanus is my best jumping spider attempt to date.  A new diffuser system and increasing comfort with using the MP-E lens in the field at higher magnification levels should allow even better photos this coming season.
