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 am not 100% sure, but I think it is a Chloroperlid. If not, it is a Perlodid (I don't think it is though). Do you have pictures of outstretched wings? Do you know the size?
