How to tie it
Lay a thread base and tie in a gray goose biot by the tip at the bend; wrap it forward in touching turns over the rear two-thirds to form a slim, segmented abdomen and tie off at the 70% point.
Tie in a sparse pinch of dun Z-Lon at 70% as a flat underwing lying over the body, reaching just past the bend.
Over the Z-Lon tie in a small section of gray CDC topped with a section of white CDC as a low adult wing angled slightly back, about one shank length long.
Split a few white and dark-gray CDC fibers out to the sides as sparse legs. Keep it thin, since an adult midge is a slender insect.
Dub a tiny gray-olive Superfine thorax and whip finish behind the eye.
