Giant Leopard Moth cats on the prowl!

The caterpillar of the Giant Leopard Moth, Hypercompe scribonia, a bit sluggish but decidedly active at a temperature of 41 F. I saw four of these large caterpillars today in Hocking County, all crossing roads. I took the liberty of helping this one across the road, and temporarily posed him on some branches for a photo.

Giant Leopard Moth caterpillars overwinter in the larval stage, and on sunny days when the temperature rises somewhat above freezing, some will become active and commence wandering about. This one had a bit of mud caked on its bristles; it had undoubtedly been under leaves or wood. Because of the GLM cats' predilection for late season and winter wandering, they are often confused with the Woolly-bear by the larvally illiterate. The Woolly-bear, as you know, is the caterpillar of the Isabella Tiger Moth, Pyrrharctia isabella, and is fabled for its alleged ability to predict winter's severity, or lack thereof.

So, people seeing roaming GLM cats may presume it to be a very dark Woolly-bear, and thus predict an exceptionally harsh winter (the darker the Woolly-bear the more severe the winter). On the lighter side, another late fall/early winter wandering caterpillar is that of the Virginian Tiger Moth, Spilosoma virginica, the Yellow Bear. This larva is also similar to the Woolly-bear but is quite pale. Misidentifications of this animal result in predictions of a mild winter.

As the Woolly-bear as winter predictor is a demonstrably false myth, none of these larval identification challenges much matters.

I've written in more detail about Woolly-bears and larval forecasting RIGHT HERE.

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…
