How to Tie the Cockroach

  1. 1

    Step 1

    Mount saltwater hook in vise. Start thread behind the eye and wrap a solid base to the bend.

    Use a strong hook designed for tarpon—they will test your tackle.

  2. 2

    Step 2

    Select 4-6 matched grizzly hackle feathers. Tie them in at the bend in pairs, curving outward. The tail should be 1.5-2x shank length.

    Match feathers for symmetry—curve them outward for a wider profile.

  3. 3

    Step 3

    Add 4-6 strands of Krystal Flash along the sides of the tail, slightly shorter than the hackle.

    Flash adds visibility in murky or low-light conditions.

  4. 4

    Step 4

    Tie in clumps of natural brown bucktail as a collar around the shank, building up a 360-degree surround.

    Add bucktail in multiple small clumps for even distribution.

  5. 5

    Step 5

    Trim the bucktail butts at an angle. Wrap thread over the butts to create a smooth, tapered head.

    A smooth underbody makes for a better-looking epoxy head.

  6. 6

    Step 6

    Apply flat tape eyes or 3D adhesive eyes to each side of the head.

    Position eyes evenly on both sides.

  7. 7

    Step 7

    Whip finish the thread. Apply 2-3 coats of UV clear epoxy over the head and eyes, rotating the fly to prevent dripping.

    Use a rotary dryer or rotate by hand until the epoxy sets evenly.
