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.

This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).
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.
Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

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.
