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.

Two major forks of this grayling stream come together in this pretty pool.

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.

Louis, I'm glad you exercised restraint. I admire your talent for crafting a fine haiku, but I wouldn't want you to run the risk of banishment.

Shawn, far be it from me to impede research in service of your "unlikely hypothesis." I know a good excuse when I hear one.

I'm guessing that it's impossible for trout to break down to the monosaccharide level and hence has little to no nutritional value to them.

Thank you Shawn,
I read your post right before I was going to post mine. Had I posted, I wouldn’t have been able to hit the delete button fast enough. My suggestion of the exuvium containing nutritional value wouldn’t have gone far.
