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.

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.

Mayfly Genus Pseudocloeon (Tiny Blue-Winged Olives)

Taxonomic History

All North American species previously assigned to the genus Pseudocloeon have been moved to other genera. However, the genus is mentioned so often in angling books that I'm keeping a page online for it as a reference to where these species were moved:

Pseudocloeon anoka = Iswaeon anoka
Pseudocloeon carolina = Acentrella turbida
Pseudocloeon dubium = Plauditus dubius
Pseudocloeon edmundsi = Iswaeon anoka
Pseudocloeon futile = Apobaetis futilis
Pseudocloeon propinquum = Labiobaetis propinquus
Pseudocloeon punctiventris = Plauditus punctiventris
Pseudocloeon turbidum = Acentrella turbida

Several other less well-known species were also moved to Labiobaetis.
