The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.

colder than a brass monkey's toes this AM in central PA so i headed south, figuring by the time i got there it would have warmed above freezing, and it did. bought a MD license and celebrated Spring with a stop at Beaver Creek. not much action on the nymph front, but then the BWOs started up sparsely and one or two fish responded. caught one stocked rainbow, one wild brown, one holdover rainbow on an Adams. thank you for the chance to share--next time will bring camera. figured net was enough bad luck this time around.

BTW, there is a crackerjack new fly shop there now in the country store building.

Congrats! Always good to get out on liquid water after a long winter. Still waiting for some sign of spring here.

At least the days are getting long. It's not dark til 9:30 at night, but everything's still frozen over.

Good job, CaseyP! Be sure to take that camera next time. The good old Adams is one of my go-to flies. Can't wait to throw a few myself, but I am a-waiting on the weather...

Hang in there Jason. My flyrodding expeditions are stalled due to cold weather and ice as well. You have my sympathies!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
