How to tie it
Start black 74 denier thread in the middle of the shank and wrap back close to the bend.
Take a medium tuft of purple saddle hackle fibers and, without trimming the tips, measure a meaty tail a little longer than the hook gape is deep. Catch it in with a couple of wraps, check the length, then add more wraps to secure and bind the butts down.
Strip a little of the fiber off the end of the medium orange chenille to expose the bare core, tie it in at the tail, and take two or three wraps to form a fat butt. Tie off and trim, then smooth the wraps out.
Bring the thread forward and tie in size 12 silver mylar tinsel with the silver side toward the hook, catching it in near the front to avoid a lump at the rear.
Tie in two strands of black ostrich herl at the front of the butt, take the thread forward, and wrap the herl forward in close turns as far as the strands reach. About halfway. Tie off and trim, then catch in two more strands and continue to the 75% point.
Wrap the silver tinsel forward over the ostrich body as an open rib. Tie it off, then fold the tinsel back over itself and add a couple of locking wraps. This makes the rib far less likely to unwind when the fly gets chewed.
Wrap a second band of orange chenille at the front for the thorax, slightly bigger than the rear butt so it helps prop the wing up. Tie off and smooth.
Stack a small-to-medium tuft of squirrel tail and tie it in as a wing reaching to about the middle of the tail. Wax the thread first, squirrel tail is slippery, and use several extra tight wraps. Trim the butts as close as you can.
Build a big head over the butts, keeping the eye clear, whip finish, and coat with UV resin or head cement.
