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.

hey eastern pa. if your looking to tie a sulpher with CDC just tie in a cdc parachute instead of the Palmer hackle that most patterns use. check out the book tying small flies, and the site flytyingworld.com, also during a sulpher hatch, you will clean up with a CDC emerger with a CDC nymph. but if your all about drys then go with the first pattern, use a size 18 hook, 16 will probably be to large and will be rejected, also look at very old patterns, in the hub bub of trying to improve things, much has been forgotten.
