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.

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.

Thank you for the nice quality pictures.

This topic is about the True Fly Family Simuliidae

Black flies are not usually regarded as important trout fare, but scientific studies of some rivers have shown them to make up the majority of the trout's diet. Such places are few and far between, but anglers should be aware of the possibility and keep a lookout for high concentrations of the larvae.

The adults are nasty, annoying, biting flies.
