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.

Saw this brown mayfly on my door the august morning i arrived in jackson hole at the Elk Refuge Hotel cross the road from flat creek in Jackson Hole.
I'm new to learning about these aquatic insects and wondered what this one is?

Hi Michael-
I believe your avatar image to be that of a male subimago (dun) of genus Callibaetis, which is also known by the common name of Speckledwinged Dun, among numerous others.
