I found this nymph in the Keystone Select section of Laurel Hill Creek, Somerset county PA. It's really small(20-24, maybe smaller). Sorry to be so vague. If anyone has an idea what it might be, I'd love to know.
If the tails are banded, rather than a solid color, then this probably is either Baetis flavistriga or something close. The markings on the abdominal terga also remind me much more of flavistriga than tricaudatus.
