How to Tie the Scud

  1. 1

    Step 1

    Mount curved scud hook in vise. Optionally wrap lead wire on the shank for weight. Start thread and secure the wire.

    The curved hook mimics the natural curled posture of a scud.

  2. 2

    Step 2

    Tie in a few short hackle fibers at the bend for the tail. Tie in the copper wire for ribbing at the same point.

    Scud tails are very short—just a few fibers.

  3. 3

    Step 3

    Tie in a strip of Scud Back or clear plastic at the bend on top of the shank.

    Cut the shellback material to about 1.5x the hook gap width.

  4. 4

    Step 4

    Dub a full, cigar-shaped body from the bend to behind the eye using Sow-Scud dubbing. The body should be fattest in the middle.

    Keep the dubbing slightly loose—you'll pick it out later.

  5. 5

    Step 5

    Pull the shellback strip forward over the top of the dubbed body. Tie down securely behind the eye.

    Stretch the shellback slightly for a smooth appearance.

  6. 6

    Step 6

    Counter-wrap the wire ribbing forward in 5-6 evenly spaced turns over the shellback. Tie off and helicopter-trim the wire.

    Ribbing segments the body and secures the shellback.

  7. 7

    Step 7

    Optionally add short antennae at the head. Whip finish and trim. Pick out the dubbing along the underside with a bodkin for legs.

    Picked-out dubbing fibers imitate the scud's many legs.
