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.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Jason: Do you have the software that will notify people by email when their questions on the forum are being addressed? If not, it would be a good idea. I'm not being critical just suggesting. The site is fantastic.

I haven't coded that into the forum yet. I know a lot of other forum software has that option, but I always considered it a little bit annoying when I keep getting emails every time there's a new reply.

If many more people are interested, though, I could probably program it as an optional feature in your settings.
