While the mayflies are hatching well, now in this warm weather, the caddises are not being left behind. One of the adult caddis patterns that I use is the Poly Caddis. It’s easy to tie, rides well in the surface film, and has the glint of reality in the winging material. It can be readily dressed in any needed size. Like the mayfly dun and spinner patterns, I tie this one with a bend hook, which keeps the wing more flat along the top of the hook and snuggles the thorax right into the surface. It lands wing up every time.
