Swallowtails and the pipevine

The area of the New River Gorge Birding Festival is among the most biodiverse in the eastern U.S. Flora and fauna abound, and at at times on a nice spring morning one hardly knows where to look. We had some utterfly fantastic field trips this year, with lots of great birds.

It wasn't only birds, though. My trip participants tended to be interested in nearly everything, so we took time to admire and learn about non-bird stuff, too.

Dutchman's-pipe, Aristolochia macrophylla. This high-climbing vine draped the timber in one of the mountain forests that we visited to a degree I've not seen before. This area, known as Sugar Mountain, was packed with birds. We had great looks at Worm-eating, Kentucky, and Black-throated Green warbler as well as many more, in addition to Scarlet Tanager, various thrushes, the ever-popular Cerulean Warbler, several species of vireo, and on and on.

In between all the avian action, our party saw scads of Pipevine Swallowtails - more than I've ever seen in any one locale. And with good reason. Their host plant, the Dutchman's-pipe pictured above, was abundant. Like most swallowtails, pipevines often course about high in the treetops, and are large enough that many a birder briefly confuses them for birds as they scan the canopy seeking out small warblers and other songbirds.

After a bit, I spotted some of the interesting flowers of the aptly named Dutchman's-pipe. As they were high up and well out of reach, a little West Virginia ingenuity was employed to secure one of the high-climbing vines and procure some flowers. These flower-pickers, who are normally quite macho, shall remain nameless.

They eventually prevailed over the vine, rewarding us with good, close looks at the odd blooms. One can see where the name Dutchman's-pipe stems from.

Soon afterward, we spotted this newly emerged Pipevine Swallowtail low on the stem of a May-apple. It's wings were still hardening and the insect fairly glistened with vibrant hues of blue, orange, and blackish-purple. Sugar Mountain was truly a feast for the eyes this day, with all of the winged wonders whirling about.

If you've not been to this part of West Virginia, I hope you can attend next year's New River Gorge Birding Festival.

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Ballooning spiders

Fear not, ye arachnophobes. The subject of this entry is indeed about spiders, but the star of the show is about as cute as a spider can get. And you'll want to know what we're about to learn...

On my recent West Virginia foray, we were strolling down a seldom-used lane, when a bright yellow object caught our eye. It was a goldenrod crab spider, Misumena vatia, on top of a post! Not only that, she - it is a girl - was acting extraordinarily goofy. The spider would stilt up as high as she could go on her legs, weave back and forth, jig side to side, and otherwise engage in what appeared to be spider break-dancing.

Click the pic for expansion, and you can see two columns of silk issuing from her spinnerets. This is an important point, as we set about determining what this non-web-making spider is doing.


So fixated was our spider on her task that she even rejected what would seem to me to be a perfectly scrumptious meal. This little caterpillar climbed rapidly up the post and dire…
