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.

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

Caddisfly Species Brachycentrus numerosus
These are sometimes called Dark Shadflies.
In Caddisflies, Gary LaFontaine attributed the famous spring hatch on the Beaverkill (now known as the "Apple Caddis") to this species. After that publication, entomologists described that major hatch as a new species -- Brachycentrus appalachia.
Brachycentrus numerosus is probably still important in many locations.
