Dry-fly hackle Grizzly or ginger hackle (one (parachute))
How to tie it
Start thread mid-shank and tie in a short piece of opal Flashabou at the bend so a bright stub trails just past the bend, the sunk 'headlight' egg sac.
Tie in a section of yellow Ultra Chenille and let it extend a half hook-gap beyond the bend; taper or singe the tip, then bind the chenille down along the rear of the shank as the low-riding body.
At the 65% mark, tie in a white calf-tail (or poly) wing post as tall as the shank and post the base with thread wraps.
Tie in a grizzly hackle at the base of the post.
Dub a yellow thorax around the post base.
Wind the hackle 4-5 turns down the post parachute-style and secure the tip.
