Trailing shuck Golden brown Antron/Zelon yarn (short tuft)
Body Stripped turkey biot (amber, to match natural) (1 biot)
Thorax Ginger rabbit dubbing (small pinch)
How to tie it
Start thread and tie in a short tuft of golden-brown Antron at the bend as a trailing shuck (the fly rides low, hanging in the film like an emerger climbing out of its nymphal skin).
Strip a single turkey biot from the stem and tie it in; wind it forward in slightly overlapping turns to form a neatly segmented abdomen over the rear two-thirds.
Dub a small ginger rabbit-fur thorax in front of the abdomen.
Build a small thread head, whip finish and add a tiny drop of cement.
Fish it in the surface film. Do not overdress it with floatant on the shuck so the rear hangs down.
