Toxomerus marginatus perhaps? Seems to be scratching his back, or is it cleaning its wings?
Wet woodlands, West Virginia USA, 16 July 2006.
ID help appreciated!

I don't think anyone will argue with your identification! :)
Its using the hairs on its hind tibia and tarsi to wipe the surface of the wing clean. Similar hairs on the front tarsus are used to clean the eyes and antennae, so it's all in perfect working order - could mean the difference between being a successful parent or a flycatcher's breakfast. ;)

Thanks Tony, that makes perfect sense. I see a lot of this kind of grooming with dragonflies, and flies too?not as often with, say, beetles. Guess it is part of relying so much on flight for defense while a beetle might just roll off the leaf or use its legs to run away. And of course some flies and all dragons rely on their wings for their supper.
