The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
I haven't really had time to ID this one; I'm just tentatively guessing based on the case that it's in Glossosomatidae.
This caddisfly was collected from Cayuta Creek in New York on April 14th, 2007 and added to Troutnut.com by Troutnut on April 22nd, 2007.
