How to tie it
Start the olive dun thread mid-shank and lay a thread base back to the bend.
Tie in a small clump of black calf tail for the tail, one shank length long, at the bend.
Tie in one end of the 1/8 in gray foam strip at the bend, then bind the thread forward to the 65% point.
Pull the foam forward over the shank to form a segmented body and tie it down at 65%; leave the tag pointing forward for now (it becomes part of the head).
Stand a clump of blue dun McFlylon upright at the 65% point as a wing post and secure with figure-eight then post wraps; trim to about one shank length tall for high visibility.
Tie in the olive-dyed grizzly saddle hackle at the base of the wing post.
Tie in 2-3 peacock herls just behind the wing and wrap them forward and around the post to build a fat thorax; tie off behind the eye.
Wrap the olive grizzly hackle parachute-style around the wing post, 4-6 turns, and tie off at the front; trim the excess.
Fold the remaining foam tag back over the thorax to form a small head/wingcase, tie it down behind the eye, trim, whip finish and cement.
