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 wild-looking little thing completely puzzled me. At first I was thinking beetle or month larva, until I got a look at the pictures on the computer screen. I made a couple of incorrect guesses before entomologist Greg Courtney pointed me in the right direction with Psychodidae. He suggested a possible genus of Thornburghiella, but could not rule out some other members of the tribe Pericomini.

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'm not sure why I had this specimen in the Baetidae to begin with. The eyes aren't turbinate and the hind wings are fairly large. I'm going to guess Paraleptophlebia at a glance, but I should come back to this one later. Any thoughts?

It's a pity the pictures are so fuzzy and dust-spotted up close. I took this picture before I really learned how to use and maintain my Canon 20D.
