Hook: 8

Mike Mercer's Gold Bead Biot Epoxy Golden Stone is a detailed golden stonefly nymph. Gold goose biots form the tails and antennae, a wound turkey biot abdomen gives clean segments, and a mottled turkey tail wing case is glossed with five-minute epoxy. Brown hen back legs and a dubbed thorax and collar finish the fly. This version stays close to the way Mercer ties it, and it takes some time at the vise. Tied here on a size 8 hook.

How to Tie the Mercer's Gold Bead Biot Epoxy Golden Stone

  1. 1

    Step 1

    Slide the gold bead onto the hook and push it up to the eye. Start the yellow thread behind the bead and wrap a base to the bend. Tie in two gold goose biots at the bend, one on each side, so they flare apart as tails.

  2. 2

    Step 2

    Lock the bead in place with thread wraps behind it, then tie in two more gold biots just behind the bead as antennae that reach forward past the eye.

  3. 3

    Step 3

    Build a tapered underbody along the shank with thread, or with a few turns of lead wire flattened with pliers if you want weight, to give the abdomen its stonefly profile.

  4. 4

    Step 4

    Tie in a yellowish-tan turkey biot at the rear and wrap it forward in touching turns to form a segmented abdomen. Tie it off and trim.

  5. 5

    Step 5

    Shade the top of the abdomen with a brown marker to add contrast to the segments.

    Optional, but it helps the biot segments stand out.

  6. 6

    Step 6

    Tie in a section of mottled turkey tail on top at the front of the abdomen for the wing case, pointing back over the body.

  7. 7

    Step 7

    Tie in a brown hen back feather over the thorax so its fibers lie along the sides as legs.

  8. 8

    Step 8

    Dub the thorax with the blend, working it between and around the legs.

  9. 9

    Step 9

    Pull the turkey tail section forward over the thorax and legs, tie it down behind the bead and trim the excess.

  10. 10

    Step 10

    Mix a small amount of Devcon 5-Minute Epoxy and spread a thin coat over the wing case. Let it set before continuing.

    Keep the epoxy off the legs and dubbing.

  11. 11

    Step 11

    Dub a small collar behind the bead, whip finish and trim the thread. Brush out the collar lightly.
