Purple False Foxglove

The short-grass prairies of Erie Sand Barrens State Nature Preserve, awash in golden and purple. The yellow flowers are those of Gray Goldenrod, Solidago nemoralis; the purple belong to Purple False Foxglove, Agalinis purpurea.

I found myself at this obscure but stunning preserve in northern Ohio recently, and was pleased to see the place looking in fine shape. It had been twelve years, probably, since I had set foot here. A botanical highlight was the expansive drifts of the foxglove, and I was struck with the urge to bring some of the plants back, in pixelated form. Some of those efforts follow.

A luxuriant foxglove provides an elegant counterpoint to the pinnate leaves of Partridge-pea, Chamaecrista fasciculata. The Purple False Foxglove is not a weedy thing, tending to occur in higher quality meadows uninfested with nonnative fare and often surrounded by other interesting native flora.

Point blank down the gullet of a foxglove flower. Note how the inner corolla is striped, and stippled with reddish dots. These are nectar guides; neon signs advertising for pollinators.

And in comes one, perhaps Nature's premier pollinating machine, at least in this neck of the woods. A large fuzzy bumblebee in the genus Bombus; an animal that supposedly lacks the appropriate aeronautics and engineering to get aloft, if you were to computer-model the beast. But fly they do, albeit in a noisily bumbling fashion, from flower to flower.

The bumblebee forcefully plops onto the foxglove's bloom, and commences to douse itself with granular pollen dust. These winged bags of fur are every foxglove's dream - a sure ticket to pollen transfer and outcrossing.

Bumblebees are not the only insects drawn to the allure of the foxglove flowers. This is a flowerfly in the Syrphidae family, doing a remarkably good job of looking stingingly dangerous. It's a ruse - the fly is a mimic of a hornet, and even buzzes like one, but it packs no punch. It and the bumblebee were part of a long parade of interesting six-legged pollinators that were lining up for the foxgloves' nectar.

We even found a rare white form of the "purple" foxglove: Agalinis pupurea forma albiflora. This form has only the slightest rosaceous tint to the petals.

Places such as Erie Sand Barrens are vital repositories of biodiversity, their abundance of life all the more striking when compared to the monocultural wastelands of beans and corn that surround this site.

The mention of the bumble bee, which according to all of our modern technology shouldn't be able to fly, clearly shows the ingenuity of the Creator of all things.

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…
