Have I got this right, Chironomidae? It looks like it to me, but with so many other families out there of various gnats and midges it would be nice to hear confirmation.

Open area near a lake, West Virginia USA, 27 August 2006. Size was 5.2 mm.

What wonderful antennae!

Seems like a long abdomen.

ID help appreciated.

Hi Stephen.
This forelegs directed ahead is very typical for Chironomidae. Male.

The fore-tarsus is much longer than the tibia - a sure give-away for Chironomidae! The antennae are similar to some mosquitoes and phantom midges. It's instructive to compare your chironomid to Xespok's chaoborid - see http://www.dipter...post_13638.
Note the difference in antenna shape, posture, leg morphology, genitalia shape and wing length.

Thanks, Nikita, and thanks, Tony. It was interesting to compare with Xespok's image. I haven't seen anything in the family Chaoboridae yet, but I will keep my eyes open!
