We came across these on the top portions of submerged rocks in the Dayton area on the Touchet this morning. This one is small at 3/4", some were up to 1 3/4" I think. Had 6? dark legs to hold on to rocks in the semi-swift water. They were everywhere. The lower sides and undersides of the rocks had the brown cone type, 1/2" with green worms, which I think are the Brachycentridae, (Grannom), but I couldn't ID these big guys. Should have taken one apart but at least I know what to imitate outside. Thx, just always curious about this stuff. Gold ribbed hares ear did fine, even though I didn't have any big enough. Some were 6 3xl long I bet.

Limnephiladae?

I like that. Thx. I skipped that 'cause my tab says identified spring lake before. But the link and book description, under closer inspection, would lead me that way. Especially the size. I swear many were more than the 1.25" long listed in the book. Maybe hatch time soon?

Hmmm, any reason they wouldn't be Dicosmoecus, a.k.a October Caddis?
Hmm. Could be? It's not in western hatchs but I see on the net it's listed with the above reference type also. I like this part of the game. I've been crawling around a lot for 3 years and I see new stuff all the time. Either way should be available all summer, I'll just see when the adults come off I guess.
