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.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.
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

Vertebrate Class Actinopterygii
These are pretty much always called Fishes.
Baitfish are a very important part of the diet of large trout, in both streams and rivers. Some streamer fishermen believe matching a particular species of baitfish may give an edge, just as hatch-matching helps fool insectivorous fish.
The specific properties of baitfish vary so widely that, given the relative unimportance of their differences, I have not yet put aside the time to write about them.
On this site, I the whole fishes section is deliberately incomplete. It's focused on possible prey for trout, and other taxa are left off the lists. I haven't put as much time into this fish section as I have into the insects, but I will start adding some good closeups of more baitfish species soon.

This seems to be a mottled sculpin, Cottus bairdi. Normally this species is more mottled.
