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.

This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.

Found this on 2/18/19 in the Kinderhook Creek, NY near Valatie, NY.
There were lots of "winter stoneflies" (Capniidae) around but this one looks different.
Any idea?
Thanks

August - Might be an Isoperla. They're usually pretty distinctively marked but some aren't. Here's a link to one that looks similar.
