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.

Limnephilus (Summer Flier Sedge) Caddisfly Larva Limnephilus (Summer Flier Sedge) Caddisfly Larva

Case view of a Limnephilus (Limnephilidae) (Summer Flier Sedge) Caddisfly Larva from the Yakima River in Washington

This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

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.

M. pulchellum is as good a guess as any, especially considering that this is a rumpled female subimago. Though, sometimes I still think I'm seeing spots (median that is).

I was looking at Randolph & McCafferty's (1998) work on Ohio and neighboring states when I referred to the M. ithaca distribution records.

When asked what I just caught that monster on I showed him. He put on his magnifiers and said, "I can't believe they can see that."

Sorry, I should have been a little clearer as far as the characters. I was asking about my comments regarding ithaca so as to answer Paul's question. Thanks for the heads up on the newer paper.

Shepherdson-

... could someone steer me toward a good ID resource(s) for Eastern flies?

The Mayfly Guide (Quick And Easy Steps To Identifying Nymphs, Duns And Spinners) by Al Caucci is my current recommendation for a mayfly identification field guide. It is a spiral-bound, has waterproof pages, is highly illustrated, is easy to use, has an enormous amount of information intelligently formatted into its (82) pages, and was published in 2011, so its taxonomy is up-to date.

Best regards,
