Photo'd on my windshield in Aug, upper Colorado, approx 7500'. Sporadic adults in the afternoon. Closest guess is Red Quill. Thoughts? edit: Probably size 14, maybe even 12. Large for the area.

Hi chewydog-

I believe it to be a male subimago of family Heptageniidae, perhaps of genus Heptagenia, which would give it a common name of Pale Evening Dun.
