Some gorgeous little bugs

Lots of bugs this weekend. Saturday night, I gave a program about "singing insects" - the Orthoptera - at Dawes Arboretum. We limited it to 25 people, and had a full house. After the presentation, we headed out into the dark and I've never had such luck finding cool bugs. Right off the bat, we tracked down and captured a Slightly Musical Conehead, the first of many. A Greater Anglewing was singing from the roof of the building that I gave the talk in. Restless Bush Crickets put in multiple appearances. And on it went - the best nocturnal singing insect foray that I've yet done.
 
Today, Jess Henning and I made a whirlwind trip into the backwoods of Athens County to check out a few spots, and encountered lots of noteworthy plants, and insects. I of course had the camera in tow, and managed some decent images. Following are a few of those...
 
A Snowberry Clearwing, Hemaris diffinis, works the flowers of a Rough Blazing-star, Liatris aspera. The dry meadow where this moth was found was full of blazing-star, and various pollinating insects. Shooting the hummingbird moths is a challenge, as they are in more or less constant motion, and their wings are a blur. When I encounter one and begin the hunt, I flip my camera's settings to shutter priority, and jack the shutter speed WAY up in order to better freeze movement. This image was made at a shutter speed of 1/2,500, with no flash.

A female Zabulon Skipper, Poanes zabulon, was also working the blazing-star. I must confess to largely ignoring the small skippers, and appreciate George Sydlowski for correcting me on its identification.

My favorite shot of the day. This is a TINY braconid wasp, and I think it is a species in the genus Atanycolus. It's a female, as evidenced by the long spikelike ovipositor protruding from the rear of her abdomen, and the entire animal was probably only 5-8 millimeters in length.

Braconid wasps are parasitoids of various insects, and species in the genus Atanycolus go after the grubs of wood-boring beetles. She'll somehow divine the location of a larva deep in a log, and auger that long ovipositor down to it, and lay an egg or eggs on the victim. The newly emergent wasp larvae will bore into their host, and eat it.

Fabulous photos , Jim. I especially admire that Snowberry Clearwing!

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…
