Start thread and run to the bend. Split two or three microfibetts into a 'V' tail one shank long, propping them on a small dubbing ball.
Dub a slim olive-brown abdomen forward to the 65% mark.
Cut, clean, and stack a clump of dun snowshoe rabbit-foot hair; tie it in standing up at the 65% mark as a single wing, tips forward.
Post a few thread wraps around the base, then push the wing to a low, slightly forward 'knocked-down' angle and lock it. This low profile sits the dun flush in the film.
Dub a small thorax fore and aft of the wing to seat it.
