Pteronarcys californica

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

This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.
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.

I need help idendifying this caddis larva I beleive it be Hydropsychidae I found it in the North Fork of the South Platte the picture is not the best but the color is fairly true. It is about 12mm long. There were several "nets" in the area and I found it under a rock in a medium speed riffle there was no "net" on the rock I found it under. I am fairly confident of the family but am not sure of the genus. Any info would be nice I am new at the "Name That bug Game".

Sundula-

I'd need to see the head capsule portion of this photo in higher resolution in order to even narrow it down to subfamily (Arctopsychinae, Diplectroninae, Macronematinae, or Hydropsychinae).

I couldn't get a good shot of the head it kept moving around. Oh well thanks for the help.

I agree that it's definitely Hydropsychidae, but it's hard from that angle to narrow it down. I notice the view-full-size link on the picture isn't working. I'll try to get that fixed tonight.
