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.

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.

This is one of my favorite stonefly pictures.  I was playing around with holding my flash heads in different locations, and I got a neat lighting effect by holding one straight above the nymph's tank.

I'm pretty sure this is Paragnetina. Can anyone who knows that genus well fill in the species?
