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.

Biography & Thoughts
I have been a fly fishing and tying instructor for about 7 years and have done some guiding throughout this time. I worked as a fisheries bioloigist for three years studying aquatic insects, trout, char and salmon in Washington State. I am now working on my masters degree at WSU in viticulture (I know, big change), but I still love to get out on the water to fish and take photographs.
