Trailing shuck Amber/brown material (Sparse tuft of Zelon or Antron)
Abdomen Olive-brown material (Pheasant tail fibers or thin dubbing)

Hackle Medium dun hackle (One feather)
Thorax Olive dun material (Pinch of dubbing)
How to tie it
Mount the hook and start the thread behind the eye, running back to the bend.
Tie in a sparse amber Zelon shuck at the bend, about half a shank long, splayed to sit low in the film. This is the trapped nymphal skin that makes a cripple a cripple.
Bind pheasant tail fibers and wrap a slim, tapered abdomen forward to the 65% mark; counter-wrap fine copper wire for durability if you want it.
At the 65% mark tie in a short upright tuft of dun deer hair, no longer than the abdomen, as the emerging wing.
Tie in a dun hackle and take 2-3 turns through the thorax, then figure-8 around the wing base to prop it up.
Dub a thin olive thorax to the eye, using half the dubbing you think you need.
Whip finish and snip. The fly should ride canted, shuck in the surface, wing tilted.
