Kogotus Stonefly Nymph Kogotus Stonefly Nymph

Dorsal view of a Kogotus (Perlodidae) Stonefly Nymph from Mystery Creek #199 in Washington

This one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.

The wings look clear enough, and the body dark enough this seems like a spinner to me. Great photo on this one and on the baetis posted the same time. Ah, yes, I see the other photos of thing bug labeled as spinners look the same.
