Saddleback caterpillar

A Saddleback caterpillar, Sibine stimulea, in repose. This one was feeding on Sugar Maple, but these caterpillars are broadly polyphagous - they can eat seemingly anything. I've found them on a variety of woody plants including Witch-hazel and Redbud, and they've even been reported feeding on corn. Saddlebacks are not infrequent in gardens, occupying ornamental plants, and perhaps you have seen one.

This caterpillar is a thing of great beauty, and the swan in a reverse ugly duckling story. The caterpillar is fantastically ornamented with dense fascicles of stinging spines, and no matter how great the urge to stroke one of these, I would resist temptation. Some authorities say that Saddlebacks pack among the greatest punches of any North American caterpillar. Those stinging spines will leave a blistering rash that will smart for quite some time. So, admire the bristly little beast wearing the lime-green horse blanket from afar. The adult phase - the moth - probably wouldn't interest you nearly as much as this larva. It is a rather plain brown Jane.

Amanda Duren spotted this animal on a nocturnal foray in Ashtabula County, Ohio, last Wednesday night. Of course, we briefly detained the animal for a photo shoot before returning it to the maples. Neither caterpillar or photographers were harmed in the process.

Whoa! Seen up close and head on, the Saddleback takes on an entirely new look, and a scary one at that. It sort of resembles a manically evil clown. Caterpillars are never boring to shoot. From one angle, something might resemble little more than a tubular bag of goo; seen from another perspective the cat might look quite cool indeed.

Wow, beautiful creature if a little scary!

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…
