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 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.

Lately I've become interested in water pennies, though I can't say why. Is a water penny nymph fly in my future?

Anyway, I took this picture today. It is a live specimen that I collected from Trout Creek, which flows into the Cannonsville Reservoir / West Branch of the Delaware river in New York in October 2013. It's current home is a 2 gallon aquarium it shares with some common stoneflies. I used a 50mm macro lens on a Cannon EOS camera with brown felt as the background. I made a special "V" shaped micro aquarium for it so that it would attach to the side wall and not the bottom so that I could get this picture.
