Trico Spinner · Dry fly
Black and white over winter water
A size 20 Trico spinner dry fly in black and white, for trout sipping tiny mayflies on slow, clear water.
A Trico spinner with a slim black body, white tail fibers and a swept white poly wing. Black thread is banded with white rib, and a spiky black thorax of dubbing and hackle sits behind a neat black head.

On the water

Stark black thread, crisp white bands, and a white wing that catches the eye against snow and grey granite. A few long white fibers trail behind, and a bristly black thorax gives the little fly some shoulders.
Fish it where trout rise in slow rhythm on flats and pool tails. Lay it a foot above the rings on a long, light leader and let it drift dead, no drag, no twitch. The white wing helps you track something this small on flat water.
Microfibbets make the tail. Split them into a wide V with a turn of thread between, and the fly sits flat and balanced in the film.

Rigging
- Tippet
- 7Xhook size divided by three
- Leader
- Nine feet, tapered — longer and finer in flat water
- Use 6X or 7X tippet and a leader of 10 to 12 feet for flat, clear water.
- Cast slightly upstream of a rising fish and feed slack so the fly drifts drag-free.
- On a flat surface, dab floatant on the wing and tail only, keeping the body in the film.

How to tie it
The steps, from first wrap to whip finish (10)
- Mount the size 20 dry-fly hook and start the black 8/0 thread behind the eye, wrapping a thin base to the bend.
- Tie in three or four white Microfibbets, about 1.5 times the shank long, and split them into a V with a figure-eight of thread.
- Tie in a length of white 8/0 thread at the bend for the rib.
- Wrap the black thread forward in a smooth, slim taper to two-thirds up the shank.
- Spiral the white rib forward in four or five even bands, tie it off and trim.
- Tie in a small clump of white poly yarn on top, angled up and back, about shank length, and trim the butts.
- Tie in a black rooster hackle with fibers about one hook gap long.
- Dub a thin noodle of black Superfine and wrap a small thorax around the wing base.
- Wrap the hackle two or three turns through the thorax, tie off and trim.
- Build a small, neat black thread head, whip finish and cut the thread.
Proportions (5)
- Tail: about 1.5 times the shank length, split into a wide V.
- Body: rear two-thirds of the shank, slim and tapered.
- Wing: roughly shank length, swept up and back.
- Hackle: fibers about one hook gap long, two or three turns only.
- Thorax: front third of the shank, slightly fuller than the body.
Tips (4)
- Flatten the thread by spinning it counter-clockwise so the body stays slim and smooth.
- Keep rib turns evenly spaced; four or five bands read clearly at size 20.
- Use very little dubbing; a thorax this small fills fast.
- Leave room behind the eye before you start the thorax so the head stays neat.
Common mistakes (4)
- Bulky body from too many thread wraps; lay one tight layer and taper with care.
- Tail fibers bunched together; separate them with a thread wrap so the fly lands upright.
- Wing too long, which twists tippet; trim it to shank length.
- Too much hackle hides the wing; stop at two or three turns.
