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.

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.
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.

Use what? a lanyard? In Montana many of the guides use them instead of a vest. One little fly box, clippers, forceps, dry fly gunk, tippet spools, what else do you need?

I've got a Dr Slick lanyard I wear when it's too hot to wear a vest...just make sure I've got what I really need on the lanyard or packed in a shirt pocket, saves time sloshing back to shore- then to the truck- to my vest to get what I forgot. They come in handy under the right conditions, IMHO.
