Hook Standard wet fly / nymph hook, e.g. Mustad 3906B or equivalent, #12-16 (tied here in #12)
Thread Black 10/0
Materials
Wood duck flank fibers Natural barred lemon (Small bunch for the tail)
Gold wire Gold wire (One strand, small)
Rabbit dubbing Dark brown dubbing (Enough for a slim abdomen and thorax)
Goose or duck quill section Gray mallard quill (One slip for the wing case)
Partridge hackle Brown hen hackle (Part of one feather for the legs)
Head cement / lacquer Clear head cement (A drop)
How to tie it
Mount the hook and lay a smooth thread base from behind the eye back to the start of the bend.
Tie in a small bunch of wood duck flank fibers at the bend for the tail, one shank-length long, and bind the butts forward.
Tie in the gold wire at the bend along the near side of the shank.
Dub a slim, slightly tapered dark brown rabbit body from the bend forward to the 65% point.
Spiral the gold wire forward over the abdomen in five or six evenly spaced turns, tie it off at the 65% point and break off the excess. If the tail has shifted, push it back into line.
Tie in the gray quill slip at the front of the abdomen with the slip pointing back over the body, then dub a fuller thorax from there to just behind the eye.
Pull the quill slip forward over the thorax and tie it down behind the eye to form the wing case; trim the excess.
For the legs, lay a partridge feather on top of the hook and take only a couple of soft wraps, then pull the feather through the wraps until the barbs are the right length (about to the hook point) rather than using the whole hackle. Lock it down and trim the butt.
Pick the legs apart with a bodkin so they sit evenly on top, then whip finish and add a drop of cement to the head.
