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 one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.

I don't know if I'm in the right section of the Forum but I recently saw an awesome photo of an Ephemerella Dorothea dun emerging from the nymphal case. The dun's wings were dry and upright but the case was still attached, about half the body length, to the dun. Is that picture on this site and if so would anyone please tell me where it is. Thanks.

Roger,
Thanks for the info but no that is not the picture I saw. It shows the dun with the opaque gray wings and the sulfur color body and the big orange eyes. Then about half way down the abdomen of the dun you can see a brown nymphal case.

I've got another sort-of-like-that photo on my invaria page but the one you're talking about is probably from another site.
