Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

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.

Hi Paul-

I believe this male imago to be Leptophlebia nebulosa.
Best regards,

Pretty. I've never seen these. Love the dark edge on the wing.

Well now that's different! Bi-colored wings on a mayfly! Thanks for posting, nice photos!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
