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

This specimen keys pretty easily to Onocosmoecus, and it closely resembles a specimen from Alaska which caddis expert Dave Ruiter recognized as this genus. As with that specimen, the only species in the genus documented in this area is Onocosmoecus unicolor, but Dave suggested for that specimen that there might be multiple not-yet-distinguished species under the unicolor umbrella and it would be best to stick with the genus-level ID. I'm doing the same for this one.
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.

Female Leptophlebia (Black Quill) Mayfly Spinner Pictures

I collected this specimen along with a female dun of the same species. Unfortunately it's not in very good shape.

After poking at it for a while under a microscope with a good scientific key in hand, I'm pretty sure this is either Leptophlebia cupida or Leptophlebia nebulosa. I can't tell which.
