This leech is a fairly simple fly, as most leeches are, and uses a custom blend of dubbing to give the fly a little variation in the color of the fly. I tie in the dubbing with a loop so that the fibers can spread out and give the fly a little more action in the water. Leeches can get hit hard by trout, so be ready for dynamic aggressive strikes subsurface. Try out some variations with the dubbing using olives, claret and brown shades of yarn mixed in with some black.
