Rio Flies UV Yum Yum Scud Stillwater Nymph can be fished as a scud or sowbug on lakes and tailwaters. Since scuds are usually more curved and sowbugs are more flat, this is a better sowbug imitation but fishy either way. The beautiful thing about impressionistic flies like this one is just get it close and let the fish decide.
