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.
Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

News reports said there were piles of these mayflies two feet deep in Wrightsville, PA.

I am not much at identifying bugs. I read about a humungous hatch of these mayflies that closed a bridge over the Susquehana River in South Central PA. (at this point the river is smallmouth water, not trout water) Can anyone identify them for me? Thanks in advance.

Kenny, see the thread entitled, "Epic Mayfly emergence" for the opinions of the gang on here. BTW, smallies take these just like trout do!! On Cooke Pond here on the Au Sable River system, I am told that even walleye will rise to a dry during this hatch!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
