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 found this dun on the same piece of stream as a similar spinner, probably of the same species.

Haven't checked any keys to verify, but most of the little late-season Cahill-looking duns are Leucrocuta. If I had to guess at the species, I'd say hebe (Little Yellow Quill). It is probably the most common L. spp. in the East and has a long hatching period that extends well into the fall.

I would also agree that the spinner you photographed is the same species.
