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.

I can't seem to be able to find my Green Drake/Brown Drake fly box....might of left it someplace or maybe it is up in my cabin but in case it is lost (over 100 emergers, duns, and spinmners) I was wondering what you PA/NY fishers use for the body? Specifically what color? do any of you color the dorsal side with brown indelible ink? I do and rib the abdomen with brown cotton thread. Thanks. A picture would be helpful.
