Tie in three pheasant tail fibers as a tail one shank length or less.
Tie in copper wire, then dub a slim, tapered abdomen to the 60% mark.
Rib the wire forward in 5-6 open turns and tie off.
Tie in a bunch of pheasant tail fibers pointing forward for the wingcase, then split a few fibers to each side so the legs emerge right at the abdomen/thorax juncture; that leg placement is what names this fly.
Dub a fuller thorax, then fold the wingcase over the top and bind it down.
Sweep the legs to the sides, build a small head and whip finish.
