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.

Kogotus Stonefly Nymph Kogotus Stonefly Nymph

Dorsal view of a Kogotus (Perlodidae) Stonefly Nymph from Mystery Creek #199 in Washington

This one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

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.
