CDC feather (emerging wing) Natural dun cdc feather (1)
Peacock herl or PT (thorax) Natural peacock herl (2 strands)
How to tie it
Lay a thread base along the curved shank down to the bend.
Tie in a short amber Z-lon (or a few pheasant-tail tips) at the bend as a trailing shuck, only about half a shank long.
Bind in a fine copper wire and 4-5 pheasant tail fibers; wrap the fibers forward over the rear two-thirds as a slim abdomen; tie off but save the wire.
Counter-rib the copper wire forward in 4-5 open turns, tie off, snip.
Tie in a CDC feather and fold a short tuft of it forward over the thorax as a low emerging wing (or take one loose turn); sweep it back and pin.
Dub or wrap a small peacock/PT thorax to just behind the eye, keeping the CDC swept back.
