Calf tail White calf body hair (A small stacked bunch (tail))
Ostrich herl Black ostrich herl (2 herls, 4-5 inches (rear and front body sections))
Floss Pink floss (1 short length (mid-body band))
Dry fly hackle White dry fly hackle (1 feather)
Head cement (1 drop)
How to tie it
Lay a base of white thread from the eye back to the start of the bend. (White thread matters. It becomes the underbody that keeps the pink floss bright.)
Stack a small bunch of white calf tail (use a little hair and the widest stacker you own) and tie it in at the bend for a long tail, about one body-length; take three wraps, then one wrap underneath to stop it spinning.
Carry the calf tail butts forward with loose wraps to build a little bulk and a white underbody, then tie down and trim the excess.
Take the thread back to the rear third of the shank and tie in a black ostrich herl; wrap about six touching turns forward to form the rear body section. (Tip: put three big wraps forward with the thread before wrapping, then back them off at the tie-off point.) Tie off and trim the herl. Ostrich must be cut, not broken.
Add a few extra thread wraps to bury the dark butt, then tie in the pink floss at the front edge of the band; wrap it back and forward again to build a solid pink mid-body band no wider than about a third of the body.
Move the thread forward and tie in the second black ostrich herl; wrap about six turns forward to form the front body section, matching the rear, then tie off and trim.
Spend a few wraps smoothing the tie-off area, then tie in a white dry fly hackle with a little bare stem exposed (strip a few barbs from the far side for a cleaner first wrap); bind the stem forward almost to the eye before trimming so there's no step-down.
Take about five wraps of the white hackle, keeping the barbs perpendicular, and tie off leaving room behind the eye.
Stroke the fibers back, whip finish a small dry fly head, trim any forward-pointing barbs, and add a drop of head cement.
