Tie in a sparse amber Z-lon trailing shuck at the bend, stubby, to imitate the trailing pupal skin.
Wrap 4-5 pheasant tail fibers forward as a slim body up to the 75% mark; tie off.
Stack a clump of elk hair, measure the tips to just past the bend, and bind it at the 75% mark so the wing sweeps back tent-style over the body; keep the butts pointing forward.
Trim the butts to form a small head, whip finish behind the eye, cement.
