Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

Doroneuria baumanni (Golden Stone) Stonefly Nymph Doroneuria baumanni (Golden Stone) Stonefly Nymph

I'm not aware of any way to tell the two species of Doroneuria apart as nymphs, so this one is classified to species based on location alone. Doroneuria baumanni is found in the Cascades and in Washington, and the other species is not known here yet.

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.

Now that the temps are hi I've put up my fly rod and I'm spending time refilling my fly boxes getting ready for the Fall & Winter fishing. Last January & Febuary I spend time on the Chattogga River. At times saw spradic hatches of Early Black Stoneflys in sizes 16 & 18, there was very little surface activity so I went to the nymph. The closet thing I had was a Pheasant Tail #16 tied from dyed black pheasant tail with a copper rib which I did ok with. Does anybody have a pattern for a Early Black Stonefly nymph in a size #16 or #18

Just a thought, Tony: The little black stoneflies that you see in Jan. and Feb. are probably Capniidae. Despite the impression given by some tying books, the nymphs are usually more of a reddish brown or yellowish brown rather than black. A standard PT would make a pretty good imitation.
