Hackle Natural gray/dun CDC wrapped around post (2)
Thorax/legs Olive Ultra Dry Dub (pinch)
How to tie it
Start thread on the black-nickel hook and tie in Coq de Leon fibers as a split tail about one shank length.
Dub a robust olive/green-drake Ultra Dry body forward to the thorax; green drakes are big mayflies, so build a fuller body than the smaller New Age patterns.
Tie in layered dun Ultra Dry Yarn wings and erect a hi-vis post.
Wrap CDC (use two feathers for the larger fly) parachute-style around the post base for maximum float.
Dub an olive thorax around the post to suggest legs.
Whip finish and cement lightly; float only the wing and post.
