Common Baskettail

Our rendezvous point for last Saturday's excursion was this place, near the shores of Adams Lake. We didn't tarry to look around the prairie in the morning, as we were itching to hit some other spots. When we returned in mid-afternoon, some of us took a stroll up the path past this sign to see if the shooting-stars, Dodecatheon meadia, were in bloom.

Almost immediately, we noticed this dragonfly on constant patrol along the woodland gap created by the trail. It remained about head high, and darted about with such rapidity that it was hard to get a good look. As we progressed up the trail, more of the same species were encountered, also hunting. In all we observed six or eight of them. I didn't know what it was, although I'm sure there are some dragonfly hotshoes out there who already know this species from the crummy in-flight photo above.

Ah! Finally a teneral (freshly emerged dragonfly) fluttered weakly by, and alit on a convenient sassafras sprig. We gingerly made our approach, and I was able to make a nice sequence of photos at close range. I still couldn't place the thing with certainty, so I dug into my favorite dragonfly book upon my return.

A common baskettail, Epitheca cynosura! Although they aren't rare, it isn't a species that I've encountered much, and I wasn't familiar enough with the animal to make the field ID. I think I'll know it now when I see it. This individual and the other more developed baskettails put on quite a show for us.

Common baskettails are members of the Corduliidae, or emerald family. They aren't as showy as some of their brilliantly green-eyed brethren, but what baskettails lack in looks, they make up for with superb aerial prowess. It was fun to watch them effortlessly patrolling on shimmering wings, and making jags at lightning speed to snap up lesser flying insects.

This teneral baskettail couldn't have made its escape from its larval shell much earlier than we found it. Its nymph probably emerged from a nearby stream the night prior, and the newly transformed adult spent the day drying on some waterside plant. We likely observed this dragon on its inaugural flight to safer haunts away from the water and all of the potential predators that can be found there. In this shot, it is grooming its frons (face) in much the manner of a cat.

This map, courtesy of the Ohio Odonata Society, illustrates that common baskettails are well distributed across Ohio. If you like dragonflies, consider joining the OOS - it'll cost you all of $5.00 a year! If you feel exceptionally generous, enlist as a supporting member. That'll set you back $10 bucks!

This chart does give some significance to our baskettail observations. It lists the earliest Ohio record as April 9, and I made these photos on April 7, so if no one has found them earlier than the 9th since the making of this map, we documented the earliest spring record.

Nice find, Ian. We also had a springtime darner very near that spot, but I couldn't get close enough for photos :-(

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…
