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.

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.

This is one of my favorite stonefly pictures.  I was playing around with holding my flash heads in different locations, and I got a neat lighting effect by holding one straight above the nymph's tank.

I'm pretty sure this is Paragnetina. Can anyone who knows that genus well fill in the species?
