Wing Calf tail or craft fur (sparse, white or tan)
How to tie it
Mount hook, tie in bead chain eyes on top of the shank near the hook eye with figure-8 wraps.
Wrap the body (clear V-Rib over flash, or plain crystal flash) from the bend up to the eyes. Smooth, slim, translucent.
Flip the hook. Tie in a sparse wing of calf tail or craft fur behind the (now underneath) eyes, so the wing rides over the hook point. The fly swims point-up.
Build a small head, whip finish, cement.
