How to tie it
Start thread behind the eye and run it to the bend.
Tie in a sparse tuft of amber Antron at the bend as a trailing shuck, half a shank long. The shed nymphal skin.
Tie in a soaked, stripped reddish-brown quill and wrap it forward in touching turns to the 65% mark for a segmented body, then give it a thin UV or cement coat.
Tie in a CDC feather (or dun poly) at the 65% mark and stand it up as a short emerger wing, leaning slightly forward.
Take 2 turns of a blue-dun hackle at the wing base, then trim the hackle flat underneath so the fly sits low in the film.
