Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.

Caddisfly Species Brachycentrus numerosus

These are sometimes called Penn's Creek Caddisflies.
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.
