Sagebrush Morning Trico Spinner

Trico Spinner · Dry fly

Spent wings on a still summer morning

A size 20 Trico spinner dry fly in black and white, with spent poly wings, for trout sipping the morning spinner fall.

A tiny Trico spinner lies spent, with long split tails and wings stretched flat. Its slim black dubbed body and thorax sit between bright white Microfibbetts and poly yarn wings.

On the water

A dry fly riding the surface of a trout river

A slender black body, barely thicker than the hook shank. White tails flare in a long V behind it. Two white poly wings lie flat out to the sides, crossed over a small black thorax. Behind it, a green river runs past dry, tan hills.

Tricos fall spent onto flats and glides, and trout settle in to sip them in tight rhythm. Put this one a foot above a riser on a drag-free drift. Let it sit flush in the film and do nothing at all.

Figure-eight wraps lock the poly yarn wings flat and square to the hook. Cross the thread between them a few times, then cover the crossing with a pinch of black dubbing so the thorax stays small and neat.

Leader
Nine feet, tapered — longer and finer in flat water
  • Rig on 6X or 7X tippet, at least three feet long, to keep the drift drag-free.
  • Fish it in the surface film; a light touch of floatant on the wings only keeps the body low.
  • Trail it behind a larger, more visible dry if the spent wings are hard to follow in glare.

How to tie it

The steps, from first wrap to whip finish (11)
  1. Mount the size 20 dry-fly hook in the vise and start the black 8/0 thread behind the eye.
  2. Wrap a thin thread base back to the bend.
  3. Tie in two to four white Microfibbetts on top at the bend, about one and a half hook lengths long.
  4. Split the tails into a wide V with a figure-eight wrap and a turn of thread under them.
  5. Dub a very thin layer of black superfine dubbing onto the thread.
  6. Wrap the dubbed body forward to about two-thirds of the shank, keeping it slim.
  7. Tie in a short length of white poly yarn across the shank at the two-thirds point.
  8. Lock the poly yarn flat and spent with several figure-eight wraps.
  9. Trim each wing to about one hook length from the tie-in point.
  10. Dub a small pinch of black superfine dubbing and figure-eight it around the wing base to form the thorax.
  11. Build a tiny head behind the eye and whip finish.
Proportions (4)
  • Tail: about one and a half hook lengths, split in a wide V.
  • Body: thin and tapered, covering the rear two-thirds of the shank.
  • Wings: each about one hook length long, lying flat at right angles to the shank.
  • Thorax: only slightly fatter than the body, filling the front third.
Tips (3)
  • Use the least dubbing you can; a spinner body should look like little more than thread.
  • Comb the poly yarn fibres straight before trimming so the wings sit flat and even.
  • Leave a clear gap behind the eye before the thorax so the head stays tiny.
Common mistakes (3)
  • Wings that ride up instead of lying flat. Add more figure-eight wraps and pull the yarn level before trimming.
  • A thick, lumpy body. Twist the dubbing tight and thin, and add more only if the thread shows.
  • Tails that collapse together. Put a turn of thread between them at the bend to hold the split.
