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.

Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva

Dorsal view of a Glossosoma (Glossosomatidae) (Little Brown Short-horned Sedge) Caddisfly Larva from the Yakima River in Washington

I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.

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.

Biography & Thoughts

New to the sport, just started at the beginning of summer 08. Looking for tips and advice how to improve faster. I just caught my first "keeper", about a 9 in. Rainbow on 8/9/08. I fully intend on practicing catch and release for most catches, but I have to enjoy some of the fruits of my labor too.

As with probably most "noobs", I'm finding the fish, just not able to get them to go after my flies... or at least not the large ones. I am wide open for advice and tips, if anyone has any. Please feel free to share. As I say, I'm a "noob" right now, so I need all the advice that I can get.
