Nymph
Stonefly Nymph
Intermediate
Trout
Steelhead
Hook: 6-14

Named for its ability to catch trophy trout, the 20 Incher combines a peacock herl body with a Hare's Ear thorax and partridge legs for a buggy, natural stonefly profile. The peacock herl provides natural iridescence while the spiky dubbing thorax suggests legs and movement. A proven big-fish pattern.

How to Tie the 20 Incher Stonefly

  1. 1

    Step 1

    Slide the bead onto the hook if using. Secure the hook and add optional wire weight behind the bead. Start thread and build a smooth base to the bend.

  2. 2

    Step 2

    Tie in two brown goose biots at the bend, splayed outward for the tail.

  3. 3

    Step 3

    Tie in copper wire for the rib at the tail base.

  4. 4

    Step 4

    Tie in 4-6 strands of peacock herl at the tail. Twist the herls together with the thread for reinforcement, then wrap forward to the 60% mark on the shank.

    Twisting peacock herl around the thread creates a 'herl rope' that is far more durable than individual herls.

  5. 5

    Step 5

    Counter-wrap the copper wire rib forward through the peacock herl body. Tie off and trim.

  6. 6

    Step 6

    Tie in a slip of mottled turkey tail at the thorax for the wingcase.

  7. 7

    Step 7

    Dub a generous, spiky thorax with Hare's Ear dubbing. Leave plenty of guard hairs sticking out.

  8. 8

    Step 8

    Tie in a Hungarian partridge feather and wrap 1-2 turns as a collar for legs. Sweep the fibers rearward.

  9. 9

    Step 9

    Pull the turkey wingcase forward over the thorax. Tie down behind the bead. Whip finish and cement.

    Apply UV resin over the wingcase for added durability and a subtle shine.
