Blue-winged Olives
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 little pool in update New York is enjoyed by many tourists every day, and it still holds a few trout -- stockers mostly, but you can't complain about the setting!

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.
