Mourning Cloak

Glorious mourning cloak struts its stuff early

Few creatures are more surefire signs of spring than the butterfly.

The sight of one of these gossamer-winged beauties flitting along on the season's first warm breezes is indeed welcome after the brutal winter just past.

One of the first Ohio butterflies to emerge and welcome spring is also one of the showiest species on the globe. The mourning cloak ( Nymphalis antiopa) is a jaw-dropping whopper insofar as butterflies go. With a wingspan that stretches the tape to 4 inches - like the familiar monarch butterfly - mourning cloaks are easy to spot.

If you see one, sneak in for a good look. Cloaks are extraordinary; painted in a background color of rich, velvety ebony-purple. The wings are trimmed in brilliant gold, as if gilded by elfin butterfly goldsmiths.

A row of tiny azure-blue dots stitches the margins of the gold, creating a fantastic tapestry of design that would turn Martha Stewart green with envy.

The Brits have coined a suitably magnificent name for this cosmopolitan stunner: the Camberwell beauty.

Mourning cloaks are perhaps our longest-lived butterfly. Some individuals can survive for 10 months or more. The adults spend winter in sheltered areas such as bark crevices or woodpiles. The first warm days bring them out: On a March 7 foray, with temperatures in the 50s, our group saw our first cloak of spring.

Butterflies and native plants are intimately intertwined. The larvae, or caterpillars, require specific plant species that provide the right nutrients and chemicals to spur their growth.

Thus, the butterfly seeks out certain suitable host plants upon which it lays its eggs. In the case of the mourning cloak, birches, willows, elms and hackberries are the fodder that ultimately cast this sensational butterfly to the skies.

You can help by learning more about native plants and planting them in your yard. By picking the species favored by particular butterflies, you might enrich your local turf with these winged wonders.

A good resource for learning more about Ohio butterflies and their host plants is the book Butterflies of Ohio by Jaret C. Daniels. Look for it in bookstores and on

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…
