Materials
Coq de Leon fibers Speckled brown/black coq de leon fibers (About 6 fibers for tail)
Micro metal or fine wire Black wire (1 length for rib)
Pheasant tail fibers Black pheasant tail fibers (About 10 for shellback, 12-15 for wingcase)
Ostrich herl Grey polar fibre (1 strand for body, 2 for thorax)
Hen hackle or pheasant rump fibers Natural speckled/mottled hen hackle or pheasant rump fibers (A few fibers for legs)
How to tie it
Lay a waxed thread base along the shank down to the bend, wax the Nano Silk well, as GSP thread is slippery.
Pull about 6 Coq de Leon fibers from the stem and tie in a tail slightly less than one shank-length long. Take a couple of wraps under the tail butts to kick it up, and pass a wrap up through the clump if you want the fibers slightly split.
Tie in the black micro metal rib and bind it down to the tail without disturbing the tail angle.
Cut the tips of about 10 black pheasant tail fibers flush and tie them in by the tips at the bend for the shellback, leaving them pointing rearward.
Tie in one grey ostrich herl by the butt at the bend (strip a little bare stem first), then wind the thread forward to the 65% point where the thorax will start. Keep the body slim.
Wind the ostrich herl forward in touching turns to the 65% point, lock it down, and trim. Moisten your fingers and stroke the ostrich fibers down so the shellback lays flat.
Pull the pheasant tail shellback over the top of the body, tie it down at the 65% point, then wind the rib forward in about 5 open turns, wiggling it through the ostrich so you trap as few fibers as possible. Take a few extra wire wraps at the thorax for weight, fold the wire tag back and bind over it before breaking it off.
Tie in 12-15 black pheasant tail fibers (cut a little below the butts) facing rearward for the wingcase, then tie in two ostrich herls and build a slightly fatter thorax with them.
Tie a few speckled hen fibers along each side as legs, fold the wingcase over the thorax, tie it down behind the eye and trim.
