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.

Personally I like to dig up dragonfly larvae or those cream colored caddis worms in the stick cases and dead drift them under a Thill float with my centerpin outfit down the seams and runs of all the central and north central PA streams and rivers.
