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.

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 Family Rhyacophilidae

These are often called Green Sedges.
See Rhyacophila for details. It is an extremely important trout stream genus, containing well over 100 American species.

The other genus, Himalopsyche, contains only one relatively unimportant American species.

Rhyacophila (Rhyacophilidae) (Green Sedge) Caddisfly Pupa from the Long Lake Branch of the White River in Wisconsin
I collected this pupa and several like it from the same stream and on the same day as this larva. I suspect they're the same species. Every pupa I collected was in a brown casing like the one shown in one of the pictures below. I cut this pupa out of its case after a picture so you can see more details. It is close to but not fully developed.
