Woolly-bears: fuzzy forecasters

A "woolly-bear", possibly the most recognized caterpillar in these parts. It's the larva of the Isabella Tiger Moth, Pyrrharctia isabella. Countless thousands of people can instantly recoginze the caterpillar; probably only a minute fraction of a percent could identify the moth.

This has been a boom year for moths and butterflies, and you can count in the woolly-bears. I've already seen scores of them, mostly crossing the roads, and many others are reporting lots of the little tubular fuzzies. Woolly-bears are stricken with a wanderlust in late fall, and that's why we see them roaming far and wide.

A well-known old wive's tale has it that the severity of the coming winter can be forecast by the woolly-bear's stripes. A big wide brown band and it'll be a mild one. Mostly black, and the bear is telling us we're in for a frigid winter. The bear above, being dominated by brown, is indicating an easy winter to come.

We'll see.

Hope the forecast is right and you have a mild winter.

Yes! A mild winter is what we need. I saw a woolly bear a few months ago and it told me the same thing.

Many reports of black woolly bears are coming in. I am moving to Florida!

@ Jim: Wimp!

(Maybe they aren't really wooly bears but that other what's-it-called cat that is supposed to be all black?)

Jim, I've been seeing mostly brown Woolies, so don't pack your bags yet. Those reporting the black ones must be up in the northern part of the state! I've been surprised to see a number of sulphurs still hanging on and flying this late in the season. I saw one just this past Thursday, its flight accompanied by the chirps of crickets in the field. It always make me sad when the insects finally go silent for the season. (By the way, I'll see you in New River in May!)

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…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
