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.

Two major forks of this grayling stream come together in this pretty pool.

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.

I was leading a Canoeing trip through Northern Minnesota and one of my students claimed they saw one of what is drawn in the picture in a little pond. The only picture we have is the one the student drew. Any guesses on what he saw?

Possibly Belostoma? The drawing wouldn't be quite right, but that's the closest thing that comes to mind. I might be missing some obscure beetle larva options though.
