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?

Michael- It looks like a male subimago Callibaetis species.

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.
