I sent it in to BugGuide. Where it was promptly identified as a midge.
I thought midges were small and black, and lived to bite me. This one is large, for a midge; I didn't get a chance to measure him, but they run from about 1/2 to 3/4 of a centimetre. And he doesn't bite.
|Wonderful antennae! They identify him as a male.|
He's a male, one of the Chironomini tribe, a relative of the mosquitoes, cousin to the no-see-ums that pester us around sunset, prettier than all of them.
I took his photos and went home for a ruler, When I got back, he was gone, probably looking for a mate. If he finds her, she will lay her eggs in water somewhere, which will be difficult to find since it hasn't rained here for ages. I wish them well.
