Butterfly another buckeye popular in fall

Butterfly another buckeye popular in fall

Anything with buckeye in the name is generally popular in these parts. Thus, the common buckeye (Junonia coenia) should indeed be an esteemed butterfly.

No matter what the name, the buckeye is a beautiful bug. Its wings are like an entomological artist’s canvas, painted by a master. Buckeye-shaped spheres rimmed with ocher and tinged with violet and azure accent a brown and orange backdrop. Dashes, bars and wavy lines create striking points of interest.

A casual observer probably wouldn’t notice the butterfly’s ornate detail. Buckeyes dash low over the ground with great rapidity. On the wing, all ablur, they look like little more than a moth on steroids.

But when one alights to feast on flower nectar — whoa! Game on, and out come the cameras. A more striking lepidopteran subject could hardly be found.

This isn’t the first time I’ve written about these flashy insects. But a special award merits a repeat performance. In August, an image of a common buckeye was selected to grace the 2016 edition of the Ohio Wildlife Legacy Stamp.

Having one’s photo judged worthy to grace the stamp is a high honor, and Alice Kahn’s fine photo that made the cut, besting 170 other entries. Kahn, of Oxford, photographed the butterfly on the snowy blossoms of white snakeroot.

Most buckeyes in Ohio are immigrants from farther south. They invade northern latitudes in late summer and fall, sometimes in big numbers. When abundant, the butterflies can appearanywhere, even in weedy urban lots.

Other years, such as this one, buckeye numbers are lean. I had seen very few until last weekend, when I noticed several dozen in Auglaize County. That’s where I made the accompanying image. The buckeye is extracting nectar from the flowers of white heath aster. This abundant native plant is a vital late-fall source of energy for butterflies.

At least some northwardly mobile buckeyes attempt to reproduce here. I’ve encountered their beautiful caterpillars several times on various species of figworts, which are the butterfly’s host plants.

Whether the chrysalises survive the winter is another question. Most buckeyes found here are ones that have recolonized from farther south.

The aforementioned Ohio Wildlife Legacy Stamp is sponsored by the Ohio Division of Wildlife and is in its seventh year. Having one’s photography adorn the stamp has become quite an honor.
Previous stamps depicted the eastern bluebird, the painted turtle and the eastern amberwing dragonfly, among other interesting subjects.

Ninety-three percent of the stamp’s $15 purchase price is invested into the Wildlife Diversity Fund. Monies go to support educational material such as the free natural history booklets provided by the Division of Wildlife. Other stamp-supported projects include endangered species research, restoration of rare species and habitat acquisition.

The 2016 Ohio Wildlife Legacy Stampfeaturing Kahn’s common buckeye photo will go on sale on March 1. For more information, visit www.wildlife.ohiodnr.gov.

A blue buckeye

No, I'm not talking about a disgruntled Ohio State Buckeye fan. Or an abnormally pigmented nut from a tree. The subject is the common buckeye, Junonia coenia, one of our showier butterflies. Buckeyes wander northward in late summer and fall, and we get variable numbers of them in Ohio from year to year. Last year was a boom year; this season has brought another bumper crop. If you watch butterflies at all, you're no doubt familiar with this ornately marked species.

But you may not be familiar with blue ones. I wasn't. Brad Deering kindly shared the following photo of a luxuriantly colored specimen that he found yesterday in central Ohio.

Our colorful buckeye in repose and upstaging a normally colored buckeye. Quite the showstopper, eh? Buckeyes often have a bluish wash on the forewing, near those two orange bars, but nothing to the extent of this specimen. I imagine this individual is merely an exceptional example of blue pigment gone a bit wild.

In a quick bit of research, I didn't find much about this phenomenon, but it does surface from time to time. CLICK HERE and you'll see a photo from Flickr that is quite similar to the individual that Brad found.

And then there are THESE PEOPLE. Employing the same mentality that causes the nursery trade to ruin perfectly good native plants, they are forcing the selection of blue in buckeyes. By isolating individuals that were naturally showing blue pigment on the forewings and crossing them with each other, they have apparently created a super race of wild looking buckeyes. Hopefully they are not releasing these genetically engineered specimens to the wild. If not, kudos to them for conducting a fascinating experiment that shows how rapidly morphological changes can occur in an animal population.

If you know more about "blue" common buckeyes or have seen one, please do share.
