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.

I have seen several of these nymphs over the years but Not sure what they are or what the adult looks like. Any help would be appreciated.

Your stonefly nymph looks like Paragnetina media. This is one of the most common large perlids in much of the East and Midwest. The adults are dark-winged with yellowish bellies. They look like this: http://bugguide.net/node/view/404851/bgimage

Thanks for the ID. The Schroon is so loaded with different types of stone flies, It's hard to keep track of all of them. The big goldens (Acroneuria carolinensis) are predominate. I estimate that 80% of the trout bug volume is made up of caddis and stones. Mayflies and ants making up the final 20%.
Thanks again,
