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.

Last spring I spent a few months working on another website, then put it on hold at about 95% completion when I ran off to grad school. I finally found a few minutes here and there to finish up, so here it is:

HackleHead Fly Tying Contest

Current contests

Grand Opening Contest -- $50 Orvis gift certificate for first place, $25 for second place.

Fly Fishing Blogger Showdown -- A competition for those of you with websites. The twist is that you can use your blog to get people to vote for you. The winner's prize is pretty good, so check it out.

It also only takes about 30 seconds to add a fly, once you've got the picture, unless you add some optional details.

Head on over and try it out!!

Come on, guys... I know some of you have pictures of flies you've tied sitting around on your hard drives. Let's see them!

At least sign in and check out and rate the other flies.

Got a good start so far! People have put some really cool stuff up.

One of the best parts of the site right now is a profile of Gonzo's flies. I borrowed a couple of his flyboxes and photographed everything in them to put on Hacklehead. They're not only realistic, but lifelike and fishable, too.
