Hi folks.
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.


Thanks!

Clark - I'm pretty sure this is a member of the Baetidae family. As to the genus your guess is as good as mine. You'll need to dissect the mouth parts to figure out genus.

The more I look at it the more it looks like it might be an early instar of Baetis tricaudatus. Google it and see what you think.

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.
