Birthday beetles

It’s my birthday, and as I’ve done almost every year of my adult life I did my first “real” collecting trip of the season. Since we’re down in Florida visiting Madam’s sister, I was especially excited for the chance to see new ground and hopefully find a few Florida specialties. The day started by getting up early to watch a spectacular full-moonset over the ocean—something I’ve never seen before.

I then headed up to the Citrus Wildlife Management Area of Withlacoochee State Forest to hook up with fellow beetle enthusiast (and soon-to-be book chapter coauthor) Kyle Schnepp from the Florida State Collection of Arthropods. Although Kyle and I have previously met at society meetings, it was our first time in the field together, and I was keen to take advantage of his local expertise to help me in my quest for Florida-endemic species. The habitat was dry oak/pine sandhill woodland with a grassy understory dotted with Opuntia australis (Florida pricklypear cactus)—itself an endemic plant.

Temperatures were comfortably cool starting out due to an overnight cold front (who knew there was such a thing in Florida?), and I was filled with anticipation as I arrived at the meeting point and prepared my gear and greeted Kyle and his two companions shortly afterwards. I’d hoped to encounter Brachys leafminers, and we beat the oaks, both Quercus laevis (turkey oak) and Q. geminata (sand oak), exhaustively in search of such, but none were found. At one point, I pulled out the telescoping tropics net to see if I would have better luck accessing the upper canopy, but I had no better luck. Through it all, however, I did get a few other miscellaneous beetles and treehoppers on the former and the same on the latter along with an Anthaxia sp. Kyle also collected a Mastogenius sp. on the latter, which I hoped to encounter as well but never did, while his companions encountered single specimens of Agrilus rubroniger (a very nice find—I have but a single specimen that I collected in southwestern Missouri) and Chrysobothris chrysoela. I continued to beat the oaks but increasingly turned my attention to other things, including the pricklypears. The flowers were closed at first (due either to the morning hour or cool temperatures), but peeling back the petals I encountered a mating pair of Trichiotinus rufobrunneus (Florida flower scarab)—a Florida specialty!—plus one of the smaller, more widespread Trichiotinus lunulatus.

I pulled the petals back on a few other flowers but didn’t see anything, then encountered a fallen dead branch of Pinus clausa (sand pine). Carefully lifting and turning over the branch revealed a Chrysobothris cribraria on the branch underside—just the second buprestid of the day for me. I then ran into Kyle again, who mentioned he’d seen a Mecas sp. on a grass stem, so I began sweeping the more open areas where the grasses—still mostly last season’s dried growth—and found two in my very first pass. These proved to be the largely endemic Mecas femoralis! I would continue to sweep grasses as I traversed the open areas of the woodland, eventually collecting a nice series of 12–15 specimens. As I was sweeping, I noticed isolated plants of the endemic Lupinis ocalensis (Ocala lupine) and, on the foliage of one, a mating pair of lixine weevils that proved to be the endemic Scaphomorphus subcylindricus.

I continued to the south side of the road where I’d earlier seen the pricklypears in hopes of finding the flowers now open. Such was the case, and in addition to further specimens of T. rufobrunneus I also encountered Acmaeodera ornata and Strangalia strigosa—the latter yet another Florida specialty that I’d not previously encountered.

Strangalia strigosa (family Cerambycidae).

Additional sweeping not only increased my series of M. femoralis but also turned up a mating pair of Typocerus zebra (zebra flower longhorn), while Kyle encountered a single Lycochoriolaus lateralis—apparently a mimic of lycid beetles, distasteful to predators, and yet another species I’d never encountered before. After nearly five hours, I decided to call it a day and started working my way back to the car. Along the way, I encountered a patch of Serenoa repens (saw palmetto) in flower. There was quite a bit of insect activity buzzing around the inflorescences, and a closer look revealed a variety of bees and a few Zelus longipes (milkweed assassin bugs) but few beetles of then oedemerids (false blister beetles). Then I noticed something “lycid-like” approaching the inflorescence, but something about it gave me pause. When it landed, I realized it was another L. lateralis. I was able to pick it up easily (it was not skittish as are most other longhorned beetles, perhaps because it relies on its mimicry to avoid predation), and further searching resulted in a fine series of nearly a dozen individuals, along with one more S. strigosa. Those would be the last insects collected, as beating oaks along the way back to the car still turned up nothing. I suppose I’ll need to make another trip down here if I want to collect Florida Brachys!

On the way back south (though not exactly “on the way home”), I stopped off at the Richloam Wildlife Management Area of Withlacoochee State Forest. Unlike the dry sandhill forest I’d just visited in the Citrus unit, the habitat here is wet sand forest. I was hoping to find stands of sedges (family Cyperaceae—usually found in and along wetlands) that I could sweep in the hopes of finding species of Taphrocerus—a genus of Buprestidae whose North American fauna I’ve been slowly revising over the years. These so-called “sedgy-wedgies” mine the leaves of various species of sedges, and there are still a few species of the genus that I haven’t yet myself collected—including the endemic T. floridanus. Kyle had recommended a location where I might find such sedges, which were abundant along the roadside. I swept them thoroughly, but to no avail.

As I was sweeping, a truck stopped and the driver called out to me and said “I just wanted to let you know I’ve already seen four or five good-sized rattlers here!” I thanked the man for his warning—though in reality I very well may have seen more rattlers in my lifetime than him. The man lingered as I returned to what I was doing—seemingly disappointed or surprised that his warning didn’t result in my immediate withdrawal. I suppose he was expecting me to run back to the car screaming like a little girl who’d just seen a spider. I was actually really hoping to see a rattler afterwards and was disappointed that I did not. The forest at this point was impenetrable, so I walked about a quarter-mile down the roadside, checking the flowers of Rosa palustris (swamp rose) along the way and being surprised to not see a single beetle—or any other insect, for that matter—upon them. In fact, the only insects I saw on anything were two very large “caterpillars”—actually larvae of Cimbex americanus (elm sawfly), a primitive wasp—on Salix caroliniana (Carolina willow).

I crossed the road to walk the other side and soon ran into an Ilex cassine (dahoon holly) tree in full flower that was leaning over the roadside.

I saw a mating pair of Lyconotus lateralis (family Lycidae) on the flowers—their presence alerting me to the possibility of finding their longhorned beetle mimic, Elytroleptus floridanus. Despite finding perhaps a dozen lycid beetles, I found no E. floridanus. Another holly tree further up the road also hosted lycids but no longhorned beetles.

Continuing a quarter-mile the other way past the car and further sweeping of sedges along the way back to the car was fruitless, and the lateness of the hour told me my insect collecting activities for the day had finally come to an end. Neverthess, I was content with series of several nice beetle species in my bottles, including a few true Florida specialities, and made my way back home.

Lewis Ocean Bay Heritage Preserve & Wildlife Management Area

The pine flatlands of the southeastern Coastal Plain offer an interesting contrast to the upland forests of my home state of Missouri. Closed canopies of oak and hickory are replaced by open canopies of pond and longleaf pine. Dry glades—islands of prairie dotting the forests—are replaced by bogs and bays—oases of wetland punctuating the sandy scrub. In both places, however, fire plays an important role in shaping and preserving these unique habitats. In this ~10,000-acre preserve, prescribed burns spare the heat-tolerant pines—their trunks blackened and scorched but the living branches high above unharmed—and prevent woody shrubs from choking out herbaceous plants, including famously insectivorous plants such as Venus fly traps, sundews, and pitcher plants. I had yet to have seen any of these plants in their native habitats, and after learning of this place and their presence here from a local resident, Madam and I made a beeline to the preserve for an afternoon of botanical hiking.

Almost immediately after starting down the road from the parking lot, I noticed white blossoms dotting the forest floor. Approaching closer revealed them to be wild azaleas—in this case Rhododendron viscosum (swamp azalea). Individually, the petite plants with their crowns of oversized blooms were quaintly beautiful. En masse, clustered on the forest floor, they were an amazing sight to see.

The going was slow in the beginning, with something new to me at every turn. A species of Nuttallanthus (toadflax)—either N. texanus (Texas toadflax) or N. canadensis (Canada toadflax), depending on details of flower dimensions—bloomed abundantly in the sunny openings. A small purple flower was at first assumed to be a species of Tradescantia (spidorwort) but proved to be the related Callisia graminea (grassleaf roseling)—a new genus for me. A bit further down the road we encountered orange flowers that proved to be Polygala lutea (orange milkwort). This genus is represented in Missouri by several species, all having flowers of pink, yellow, or white.

Flowers were not limited to herbaceous plants. The evergreen woody shrub layer was just coming back to life with new growth, a few of which bore distinctive blossoms identifying them as members of the genus Vaccinium (blueberry). There are several potential species that could be here.

At one point, Madam called me to the other side of the road, pointing to a strange plant at the edge of a wet area and asking “What’s that?” Bingo—I recognized it instantly as one of the so-called “pitcher plants” (genus Sarracenia), among the most dramatically charismatic of the insectivorous plants. Pitcher plants trap insects using a rolled leaf with downward pointing hairs on the inside and the uppermost part of the leaf flared into a lid (or operculum) to prevent rain from diluting the digestive secretions pooled at the bottom of the leaf. Though a bit past bloom, it was easily identifiable as S. flava (yellow pitcher plant). We were thrilled to have seen our first pitcher plant in the wild, and we looked forward to seeing more (hopefully in full bloom).

As we scanned the edge of the wetland looking for more pitcher plants, I noticed tiny white flowers on the small shrubs underfoot. They looked rather “hollyish” to me, and indeed they proved to be Ilex glabra (gallberry), a species of evergreen holly native to the coastal plain of eastern North America and most commonly found in sandy woods and peripheries of swamps and bogs.

At this time of season, I was expecting to see insects well active, and this was certainly the case with butterflies—the most common being a species of swallowtail that oxymoronically reminded me of a small giant swallowtail (Papilio cresphontes) but in reality were Papilio palamedes (Palamedes swallowtail). I’m a beetle guy, however, so I was happy to find a few Acmaeodera tubulus jewel beetles on flowers of Erigeron sp. (fleabane), and when I saw a standing recently-dead pine beyond the wet drainage I decided to check it for other jewel beetles on its trunk. As I started to step across the water, a small purplish plant on a piece of wood in the water caught my eye, and I immediately recognized it as one of the sundews (genus Drosera), another genus of insectivorous plants that capture and digest insects using stalked mucilaginous glands that cover their leaf surfaces. This is one of the largest genera of insectivorous plants, but I take this one to be D. intermedia (spoonleaf sundew).

About a mile and a half from the car, we finally found what we had been hoping to see since soon after we arrived—Sarracenia flava (yellow pitcher plant) in full bloom. A rather large patch of them was visible from afar, their yellow blooms glowing in the sunlight, but sadly most of them were slightly or greatly past peak bloom. A bit further back, however, on the other side of the water, I spotted two single plants in perfect bloom, their petals fresh and intact and making the effort to find a way across the water well worth the effort. Other plants without blooms but with fresh, brightly colored “pitchers” were also seen along the water’s edge.

As we admired the spectacle in front of us, I noticed a clump of red within the vegetation at water’s edge and realized we were looking at another species of pitcher plant—Sarracenia purpurea (purple pitcher plant)! How fortunate we were to see this clump—the only one we saw—which was in perfect bloom and with colorful, freshly-formed pitchers whose squat form contrasted notably from the tall, slender, graceful pitchers of S. flava right next to it.

By now, the April heat had taken a noticeable toll on the conditioning of these two recently-escaped-from-winter Midwesterners. Having found the Holy Grail for the day, we began the long, tired slog back to the car—our legs dragging but our spirits soaring.
