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.

This species was fairly abundant in a February sample of the upper Yakima.

This is a uenoid. I know the genus, but I can't think of it now...sorry, I'll try to remember to look it up if no one else knows it.

David-
Probably Neophylax (Autumn Mottled Sedge). This genus has four species in NY. Most likely it’s N. concinnus, as this is the only one (of those four) that Gary LaFontaine considered to be sufficiently important to flyfishers to include in his book. However, the other NY resident species are N. consimilis, N. fuscus, and N. oligius.
