I only used 6 ingredients for this guy, and I'm pretty happy with the results. Imitation wood duck feathers make the claws and tail, 30 lb mono for the eyes, copper crystal dubbing for the mouth parts, dubbing, brown hackle for legs, and a heavy wire to segment the body. I used heavier crafting/beading wire to assist the lead weight in getting this guy deep. This one, and the others in the batch, are tied in size 8.
I came up with this when I found that every pattern for a crawfish imitation I could find had at least one or two materials that I don't have and have never used on any other fly before so I sat down with a pile of materials, a stiff whiskey, and a determined mind to come up with something. My buddy has been severely outfishing me in warm water with his crawfish, so I had to come up with something to even the odds.
