Blue-winged Olives

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.

Just found this web site and have to say this is the most informative and detailed one I've found.
I live in PA and fish the Little Juniata. I never seem to hit the early black stoneflies. When is the best time for them? And after looking at these photos I believe my pattern ain't what it should be. I know these photos are from a sample out west but are they similar to our eastern blacks?
