This is a simple to tie Caddis Pupa patten. The abdomen, comprised of Diamond Braid, can be changed in color. The thorax dubbing blend and bead head can also be changed color wise. I have always tied this with a light green or tan Diamond Braid. Note the singed tip at the end of the braid, which stops it from unraveling. A fast sinking, small pattern that is simple to tie. Put on the bead, tie in the abdomen from mid shank to just behind the bead and then dub over the abdomen tie in point up to the bead. Keep it scraggily/buggy looking (fibers extending out to provide movement/suggestion of antenna, legs, emerging wings).
