Hook: 10-16

The quintessential simple fly—a bright chartreuse chenille worm that imitates inchworms and caddis larvae. Originated in Pennsylvania and became a staple across Eastern streams and beyond. Deadly effective from spring through fall, especially near trees where inchworms drop. One of the first flies every beginner should learn. Fish dead-drifted under an indicator or tight-line for consistent results on trout.

How to Tie the Green Weenie

  1. 1

    Step 1

    If using a bead, slide it onto the hook before mounting. Place hook in vise.

  2. 2

    Step 2

    Start chartreuse thread just behind the bead or eye. Create a smooth thread base down toward the bend.

  3. 3

    Step 3

    Cut a strip of chartreuse ultra chenille. Strip a short section of fibers to expose the core.

  4. 4

    Step 4

    Tie in the chenille at the bend. To form the signature tail loop, fold back about one-quarter to one-half inch of chenille and secure the base of the loop with thread wraps.

    The loop tail mimics the natural curling posture of an inchworm. Some tiers skip this for a simpler version.

  5. 5

    Step 5

    Wrap the chenille forward in tight, touching turns up the hook shank to just behind the bead or eye.

  6. 6

    Step 6

    Tie off the chenille, trim excess, form a neat thread head, whip finish, and apply head cement.
