Materials

Tying Instructions

  1. 1.

    Secure a size 18–24 standard dry-fly hook in the vise and start the black thread one eye-length behind the eye.

  2. 2.

    Tie in a sparse strand of white polypropylene yarn at the thorax point with crossed figure-eight wraps, positioning the wings flat and perpendicular to the hook shank.

  3. 3.

    Trim each spent wing to about one hook-shank length from the centerline.

  4. 4.

    Wrap the thread back to the bend, keeping the underbody smooth and thin.

  5. 5.

    Tie in two black dry-fly hackle fibers at the bend with the tips extending about one and one-half shank lengths beyond the hook.

  6. 6.

    Divide the tails with a figure-eight thread wrap or a small thread bump so they spread evenly.

  7. 7.

    Dub a very thin black abdomen forward from the bend to the spent-wing tie-in point.

  8. 8.

    Tie in a grizzly dry-fly hackle by its stem immediately behind the wings.

  9. 9.

    Build a compact black dubbed thorax around the wing base without forcing the wings out of the spent position.

  10. 10.

    Wrap the grizzly hackle two turns through the thorax, tie it off ahead of the wings, and trim the waste.

  11. 11.

    Form a small thread head behind the eye, whip finish, and apply head cement sparingly.
