How to Tie the Callibaetis Spinner

  1. 1

    Step 1

    Begin thread two eye-lengths back from the eye, wrapping a smooth base to the bend.

  2. 2

    Step 2

    Select 2-4 Microfibbet tail fibers. Secure at the bend, splaying outward for a realistic split. Tail should be about shank length.

  3. 3

    Step 3

    Tie in a turkey biot at the base of the tail, curved side up. Optionally apply thin super glue to the shank for durability.

  4. 4

    Step 4

    Wrap the biot forward in slightly overlapping turns to create a segmented, slender abdomen. Stop at the thorax region.

    Cut the biot tip off for easier handling.

  5. 5

    Step 5

    Tie in wing material perpendicular to the hook at the thorax. Keep wings flat/spent. Secure with figure-eight wraps. Trim to shank length.

  6. 6

    Step 6

    Dub a thorax of superfine Callibaetis-colored dubbing in front of and behind the wings, building a gentle hump.

  7. 7

    Step 7

    Optionally add a small bright UV orange sighter post above the wing for easy tracking on still water.

  8. 8

    Step 8

    Whip finish behind the eye. Trim excess. Apply a small drop of head cement.

    Fish with a long leader (12-15 feet) and 5X-6X tippet for natural drift.
