How to tie it
Start the black thread and tie in a short upright clump of fluorescent orange poly yarn at about the 65-70% point as the visibility post.
Tie in white poly (or Zelon) spent wings across the hook at the same point, splayed flat out to each side (90 degrees) in the classic spinner silhouette.
At the bend, tie in white/dun Microfibett tails split into a wide V, about a shank length long.
Build a slim black abdomen with thread (or a whisper of black dubbing) from the tail to the wings.
Dub a tiny black thorax over the wing/post base to lock everything, forming the crossed 'spent' wing.
Whip finish behind the eye and keep the head tiny.
