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 specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive 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.

The 5 am mist rises off a classic hole on a favorite river. I'd just spent the last few hours of that moonless night working this hole with big pusher flies in the pitch black darkness, running on caffeine until about 4:15 and adrenaline from that point on, after feeling a whale of a brown trout on my line for about 15 seconds. Unfortunately the fish spit the hook, but it was an unforgettable experience.

I found this spinner and a few of his friends bobbing above the river amidst a snowstorm hatch of white Ephoron flies.
