The amazing Net-winged Beetles

I was at one of my favorite natural areas in Ohio the other day, the always interesting Cedar Bog. If you've not been to this 400+ acre fen, put it on your list. There is never a shortage of fascinating flora and fauna, and this day was no exception.

There were numerous beautiful plants to admire and photograph, such as this Prairie Rattlesnake-root, Prenanthes racemosa, which is an Ohio rarity. Not long after making this photo, a subtle blur of orange and black whirred by, low through the foliage.

A Net-winged Beetle! I love these things. While they may not be great rarities, I don't see that many of them and it's always a treat to stumble into one. We apparently have several species, and this one is Calopteron terminale, and it is the one that I see most often. It seems to fancy itself a lightning bug and wears the colors and patterns of those nighttime bioluminescers. I'd bet they taste bad, as Net-winged Beetles are marked in the classic DANGER color scheme.

"Nothing is known of the egg stage and oviposition site of Calopteron species."

So states a University of Florida website on this beetle genus. There are so many things that we still know so little about, and apparently Net-winged Beetles fall into this camp.
This is a different species, Calopteron reticulatum. It may be even better looking than the one above. Photographed last August in Gallia County, Ohio.

So, next time you are in shady forested haunts, be sure to investigate any lightning bug-like critters that flit past.

Another neat bug post. The "net wing" effect is really much more dramatic in person. It's really easy to see where they got their common name.

Thank you, Scott. Net-winged Beetles are a bit of a challenge to photograph, because they are usually in deep shade or dappled light.

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…
