Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

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.

I was trying out my dedicated Euro nymphing rig, having left my regular rods half a mile back in the car. This fish and others were rising to some sparse evening hatch, and nothing would even take a passing interest in my nymphs. So I put on a more appropriate dry fly and flopped it out in ridiculous form with my nymphing line/leader. This was the first nice fish on the rod (16" rainbow) and great fun, but was it cheating to break in the new nymphing rod with a dry fly?
