    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.

    That is definitely a Pale Evening Dun. These guys can bring some nice dry fly opportunities.
