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

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.
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.

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 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.

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 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.
