Flymph
This wingless wet is becoming more popular in the U.S. with Dave Hughes' book Wet Flies. I tie the fly differently than Hughes suggests, however. Dub the rear 2/3 of the shank, then tie in the hackle by the tip. Dub ahead to form the thorax. Wrap the hackle forward in two or three open spirals, then make two or three touching wraps behind the eye. Tie off, and trim. If a rib is desired (which makes the fly more durable), counter wrap it over the body and through the hackle as the final step. It is effectively fished dead drift using a dropper/dry rig.
