This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

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.

Size alone would make Stenacron unlikely, but notice the unmarked legs and that the darkest grouping of crossveins is in-between R1 and SC (Stenacron would have them between R1 and R2). Compare this specimen to the one on the Leucrocuta page--they are probably the same species.
