Blue-winged Olives
Baetis
Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This wild-looking little thing completely puzzled me. At first I was thinking beetle or month larva, until I got a look at the pictures on the computer screen. I made a couple of incorrect guesses before entomologist Greg Courtney pointed me in the right direction with Psychodidae. He suggested a possible genus of Thornburghiella, but could not rule out some other members of the tribe Pericomini.

I caught this female during her egg-laying flight.

The dark abdomen on this one is pretty striking. Does anyone know what species this is?

I probably shouldn't say anything after blowing that Paragnetina/Acroneuria ID, but I seem to recall that those black bands on the underside of the thorax are indicative of Agnetina.

Beautiful picture, this is a female of a Helopicus subvarians

Nice catch, Luke. Thanks for correcting the identity of this "cool perlodid." I wasn't very familiar with the Perlodini "springflies" when I made the earlier comment. While we're on the subject, do you recognize this one? http://www.troutnut.com/specimen/488
