Start thread at the bend and tie in a few Coq de Leon fibers for a split tail about one shank length; the stiff fibers cock the fly upright.
Tie in extra-small copper wire for the rib.
Spin PMD-colored CDC fibers into a dubbing loop or twist and wrap a slim tapered abdomen forward to the 60% mark; CDC dubbing is exceptionally light and buoyant.
Counter-rib with the copper wire in 4-5 open turns for segmentation.
Tie in a clump of natural gray CDC fibers as a wing, then split it into two with a small bundle of fire orange Fluoro Fibre, which doubles as a hi-vis sighter.
Dub a CDC thorax around the wing base, whip finish and cement lightly.
