This is one of or favorite modern mantis shrimp imitations. So clean and so "shrimpy" looking that bonefish can't resist. Bead chain eyes and epoxy head give it enough weight to sink to the bottom and ride hook up, while still allowing it to land softly enough to not spook fish or bury its way too the bottom too quickly. Its the perfect "tweener" fly when bead chain eyes alone sink a little too slow, but stepping up to a pattern with brass DB eyes cause the fly to land too hard and sink too fast.
