How to tie it
Start thread and tie in Coq de Leon fibers as a split tail about one shank length; the Spanish CDC split-wing style relies on these to balance the fly.
Dub a slim, buggy gray Ultra Dry body forward to the thorax.
Tie in layered gray/dun Ultra Dry Yarn wings and erect a hi-vis post.
Wrap CDC parachute-style around the post base for a high, stable float.
Dub a gray thorax around the post to suggest legs.
Whip finish and cement lightly; float only the wing and post.
