Art Flick (and probably others too) tied a fly with no wings called a "variant", just with a tail, body and hackle. I haven't seen a variant mentioned in the magazines for as long as I can remember. I still have a shortened hook shank for tying variants made by Mustad that is no longer made. Follow the advice of ScottP and JB above. When I first started tying dries, the wings were horrendous looking but somehow they still caught fish.
