How to tie it
Mount the hook and lash the dumbbell eyes on top of the shank near the eye so the fly rides point-up and crawls hook-up.
At the bend tie in a few rubber/flash antennae pointing rearward, then two rust rabbit-strip claws splayed in a V - claws face back, since a fleeing crawfish swims tail-first.
Tie in the shellback strip and the copper wire rib at the bend.
Dub a full rusty-orange body forward, figure-8 around the eyes, and stop behind the hook eye.
Add a set of barred rubber legs figure-8 at the midpoint.
Pull the shellback over the back and rib forward with 5 evenly spaced turns, tying off behind the eyes.
Whip finish and pick out the body dubbing to look leggy.
