This specimen keys pretty easily to Onocosmoecus, and it closely resembles a specimen from Alaska which caddis expert Dave Ruiter recognized as this genus. As with that specimen, the only species in the genus documented in this area is Onocosmoecus unicolor, but Dave suggested for that specimen that there might be multiple not-yet-distinguished species under the unicolor umbrella and it would be best to stick with the genus-level ID. I'm doing the same for this one.
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

I captured this specimen in the same color as this photograph, during its egg-laying flight. The emergers are much lighter.

this might be the only exception. "Creno" provided guidance about the small black caddis on the Big Horn River in Montana:
the ones in my face and on my clothes all had black legs. bleaahhh--they were everywhere! ahh, the joys of a good hatch...
The little black caddis of Bighorn fame is Amiocentrus aspilus. Pretty rare every where but there. The wings are iridescent black - shiny blue-greeny black. Out here we say magpie black.

Josh,
The short answer would be no, but legs that are some shade of brown or tan are pretty common. As Casey points out, some have blackish legs, and others can have rust, orange, yellow, gray, or whitish legs. Many have plain-colored legs, but some have distinctly banded legs.
