Wire, brassy size Gold or copper fine wire (One length for the rib)
Goat dubbing (any coarse natural fur substitutes) Brown dubbing (Enough for a big fuzzy body, two or three applications)
Marabou Black marabou (One big tuft for the wing)
How to tie it
Pinch the barb, start the black thread behind the eye and lay a base back to the start of the bend.
Tie in the gold or copper wire rib at the bend. A visible rib is what sets this leech off.
Dub the brown goat onto the thread and wrap a big, shaggy body all the way forward to just behind the eye; it will take two or three applications.
Trim the body roughly to shape before you add the wing.
Select a big tuft of black marabou that extends well past the bend, tie it in on top at the head, trim the butts, and take enough wraps to start forming the head before you rib it. Tying it in loosely and re-securing later makes a mess with marabou.
Wrap the wire rib forward Matuka style: part a small bunch of marabou fibres, lay them down, take the wire through the gap without trapping fibres, and repeat. About four wraps total up the top of the hook.
Watch that the wire does not skew the fibres to the far side or wrap the marabou around the hook as you go.
Secure the wire at the head with three tight wraps and helicopter it off, then take the thread forward over the sharp nub with loose wraps to bury it.
Build a big streamer head with as many wraps as it takes, whip finish, and clean up any stray marabou or goat fibres.
