I came up with this pattern a while back; a few of you suggested submitting it to the Fly Of The Week. One of my friends asked me to make them a crayfish pattern, and this is what I came up with.
I use this fly as a retreating crayfish, stripping a little line at a time. The head is weighted so the tail end jerks up and back, while the claws point downward. You shouldadjust the colors and hook size to imitate your local crawdads.
