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.

Clitelatta-Oligochaeta (Worm) Animal Adult Pictures

I know most people know what a worm looks like, but when trying to tie an imitation, the memory is often a poor source of accurate color information, and a picture helps to get the right shade. One thing that surprised me in my sampling is that quite a few worms did turn up. Before I was a fly fisherman, when I used worms for bait, I always thought they were merely a tantalizing morsel and not a regular trout food, but I've since realized that there are quite a few worms that live in the sediment on a stream bottom.

This animal was collected from unknown in Wisconsin on February 7th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
