Blue-winged Olives

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.
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.
