How to tie it
Start thread and, if you want it weedless, tie a mono weedguard stub at the bend.
At the bend tie a craft-fur tail one shank long as the mantis tail fan, add a few strands of flash, and two short antennae of stripped hackle stem or mono.
Lash dumbbell or bead-chain eyes on top near the hook eye so the fly rides point up.
Add pairs of rubber legs along the shank and dub or palmer a shaggy tan/olive body between and around them.
Carry the body forward past the eyes, pick it out shaggy, finish the weedguard loop back to the eye, then whip finish and cement.
