Code Cracker is a PMD nymph from Cheech, made as a far simpler answer to the full split case nymph. A thread body of dark mocha brown carries a Coq de Leon tail and a yellow foam wing case under thin UV resin. That bright spot is the point of the fly, since fish on the PMD hatch tend to key on a dark nymph with a bright mark on its back. Chartreuse, white or pink wing cases give them something different. Tied here on a size 16 hook.

How to Tie the Code Cracker

  1. 1

    Step 1

    Slide the black bead onto the jig hook and mount the hook in the vise.

  2. 2

    Step 2

    Start the thread behind the bead and take it back along the shank to the bend.

  3. 3

    Step 3

    Tie in a small bunch of Coq de Leon fibers at the bend for the tail. Bind the butts along the shank and trim any excess.

  4. 4

    Step 4

    Wrap the thread over the shank to build a smooth, slim body, ending just behind the bead.

  5. 5

    Step 5

    Cut a narrow strip of yellow foam from the sheet.

  6. 6

    Step 6

    Tie the strip on top of the shank right behind the bead, with the long end angled back over the body.

  7. 7

    Step 7

    Whip finish behind the bead and cut the thread.

  8. 8

    Step 8

    Touch a small drop of UV resin to the foam at the tie-in point.

  9. 9

    Step 9

    Trim the foam strip down to a short tab so only a small yellow spot remains behind the bead.

  10. 10

    Step 10

    Coat the wing case and the front of the body with thin UV resin, then cure it with a UV light.

    Swap the yellow foam for chartreuse, white or pink to change the look of the hot spot.
