Eastern Red Damsel

Small raised fen in west-central Ohio. I had the good fortune to get afield with Troy Shively the other day, and he showed me a few new fens in western Ohio. A fen is a highly alkaline wetland fed by a constant flow of artesian spring waters that have just percolated from the depths of subterranean limestone deposits. This creates very cold root-level temperatures, and in conjunction with the high pH soils, fens are a tough place to eke out a living for the vegetable crowd. The plants that do grow there are highly specialized and extremely interesting; ditto for the animals.

The yellow flowers dotting the fen are of a beautiful woody plant, Shrubby Cinquefoil, Dasiphora fruticosa. There are few better fen indicators than that species. Essentially, if you find wild-growing Shrubby Cinquefoil in Ohio, you are probably semi-mired in the wet mucky soils of a fen.


While Troy and I found many noteworthy critters, I was delighted to run across what may be my favorite damselfly. The Eastern Red Damsel, Amphiagrion saucium, is impossibly tiny - nearly our smallest species. They're easy to miss, and for a six-footer standing upright, they're nearly invisibly as they silently whir low in the sedges along the margins of chilled flowing rills.

I devoted some time to Red Damsel stalking, and was eventually rewarded when one of them made a kill, and settled to consume his gnat-sized prey. With some bitternlike swaying and stalking, I was eventually able to get my camera barrel within six inches of the damsel and obtain some decent shots.

In the above photo, the damsel is perched on a rare plant, for Ohio at least, and in fact is surrounded by rare plants. At least they are far rarer than once was the case, as we've managed to obliterate well over 90% of the fens that once pocked Ohio's landscape. Anyway, its perch is Walking Spikerush, Eleocharis rostellata, an obligate species of fens and often a dominant. This sedge essentially spreads by walking; as the stems elongate, they bend to the point where the tip eventually contacts soil. This stimulates specialized tissue formation, and from there a new stem is sent out, thus the plants walk themselves into new terrain.

Back to the damsel, and aren't they a gorgeous shade of deep red with perhaps a tinge of orange mixed in. I've caught his eye here, and he's turned to give me a piercing stare. Lucky for me he isn't the size of a Tundra Swan or it'd be your narrator being crunched and munched rather than that gnat.

Like so many things in nature, the Eastern Red Damsel is not obvious. By taking time to investigate the superficially obscure, like this insect, one is often rewarded with the opportunity to admire something that puts many of our larger showier creatures to shame. You've just got to get close.

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…
