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.

Hi,

is it possible to identify this species from Kentucky, 24.9.2007? The winglength is about 17 mm.

Jukka, the pattern on the wings looks like Agrypnia vestita to me, but that's a guess. Dave Ruiter (Creno) is the caddisfly expert. Perhaps he will take a look at your specimen.

Like Gonzo, I would guess Agrypnia vestita based on color and location. However I looked at alot of A.vestita specimens (and a few other Agrypnia species) and could not find one with the apical fork of hindwing R2 that appears to occur in your photo. Is that fork really there or could it be a fold from spreading?

Many thanks for your comments :)
To Creno: the fork is not real, it is a shadow, because the surface is not smooth.
