An odd fern

Southern adder's-tongue, Ophioglossum vulgatum. I had the good fortune to stumble into a small colony of these weird little ferns yesterday, in Adams County. The adder's-tongue ferns scarcely resemble their more pinnate, cut and dissected allies, and one could be forgiven for wondering what the heck one of these things is. In Ohio, their closest relatives are the grape ferns in the genus Botrychium, but the adder's-tongues don't look much like those, either.

We've got three species of Ophioglossum: this one, the Northern adder's-tongue, O. pusillum, and the very rare limestone adder's-tongue, O. engelmannii. Both of the other species are listed as endangered in Ohio, with the limestone adder's-tongue found elsewhere in Adams County in a few prairies.

Southern adder's-tongue likes to grow in scruffy haunts such as young woods, field margins and other semi-shaded uninteresting places that people often don't look at very closely. And it's quite easy to walk right by this plant, the eye dismissing it as the young leaf of some young plant still on the rise.

Excellent find! I love these species of Ferns, and unusual they are indeed! I have Ophioglossum engelmannii high on my life list.

Thanks Andrew, and I know just where to go for O. engelmannii. Would have looked yesterday but time didn't allow...

Anyway, you should have no problem finding that one with a few directions, should you need them.

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…

Ballooning spiders

Fear not, ye arachnophobes. The subject of this entry is indeed about spiders, but the star of the show is about as cute as a spider can get. And you'll want to know what we're about to learn...

On my recent West Virginia foray, we were strolling down a seldom-used lane, when a bright yellow object caught our eye. It was a goldenrod crab spider, Misumena vatia, on top of a post! Not only that, she - it is a girl - was acting extraordinarily goofy. The spider would stilt up as high as she could go on her legs, weave back and forth, jig side to side, and otherwise engage in what appeared to be spider break-dancing.

Click the pic for expansion, and you can see two columns of silk issuing from her spinnerets. This is an important point, as we set about determining what this non-web-making spider is doing.

So fixated was our spider on her task that she even rejected what would seem to me to be a perfectly scrumptious meal. This little caterpillar climbed rapidly up the post and dire…
