The pheasant tail nymph is a classic nymph pattern.  Tied with its traditional materials of natural pheasant tail fibers and peacock herl it is a fish catching wonder.  The color scheme of the natural materials does an excellent job imitating many mayfly nymphs.  A pheasant tail nymph is a killer nymph pattern for panfish.  You may ask the question “If this pattern works so well why mess with it?”
