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.

A 17" brown trout who ate my wet fly imitation, early morning. (He was released right after photo.)

It appears the females have long, slender yellow egg sacks.

This morning on one of my favorite NW Wisconsin streams I found Ephoron leukon spinners and duns covering spider webs near the stream. Also, a wet fly version of Ephoron leukon worked great at catching trout still looking for the little white mayflies.

Great photos John! I've gotta say I miss that river, hard as it may be to complain about my present situation. :)

Jason, I never said what river! :-)

It's hard to compete with your terrific digital shots! Especially with my el cheapo point-and-click camera. Of course, even if I had the more expensive stuff I still wouldn't know how to use it. I need a mouse and a keyboard for everything. :-)
