Debarb, slide the copper bead to the eye, and start the olive thread behind it, laying a base to the bend.
Tie in 6-8 pheasant tail fibers by the tips at the bend, leaving the tips out as a short tail about half a shank long; bind the butts and the chartreuse wire down the shank.
Wrap the pheasant tail fibers forward as a slim abdomen to the 60% mark and tie off.
Counter-wrap the chartreuse wire forward over the abdomen in 5-6 open turns and tie off, then helicopter the tag to break it.
Tie in one brown goose biot by its tip at the 60% mark, pointing back over the body, concave side up, for the wingcase.
Dub a slim dark-olive thorax forward to just behind the bead, then tie two strands of pearl Krystal Flash along the sides as legs, trimmed to the hook point.
Pull the goose biot forward over the thorax as a wingcase, secure behind the bead, trim the excess, whip finish, and cement.
