Body Rusty brown/orange (Simi-Seal or crawdad dubbing, shaggy)
Resin Clear uv resin (UV resin over the eye wraps)
How to tie it
Mount the hook and lay a thread base; bind the lead barbell eyes on top of the shank a shank-quarter behind the eye so the fly rides point-up, then lock them with figure-8 wraps.
At the bend, tie in two rabbit-strip claws splayed into a wide V, each about one shank length, hide facing out so they flare when stripped.
Add a pinch of copper flash and a pair of barred silicone legs as antennae, sweeping back past the claws.
Dub a shaggy Simi-Seal body forward, stopping at the 70% mark; pick out fibers underneath to suggest legs.
Tie in a second pair of silicone legs at the sides, splayed out like walking legs.
Figure-8 dubbing around the barbell eyes to build a crayfish head, sweep the fibers back, and whip finish behind the eye.
Add a drop of UV resin over the eye wraps to lock everything down.
