October Caddis (Orange Stimulator)

October Caddis are huge — up to 1.5 inches — and their emergence in fall triggers some of the most aggressive surface feeding of the year. The Stimulator tied in orange and yellow effectively imitates the egg-laying adults crashing onto the surface of Western rivers like the Deschutes, Rogue, and Yakima. Fish it on a short leader with confidence, skating it along current seams.

Tying steps

  1. Mount a size 6–10 3XL dry fly hook; start orange thread and wrap to bend.
  2. Stack a bunch of bull elk hair; tie in as a tail at the bend.
  3. Tie in a palmered brown hackle at the rear and a ribbing of fine gold wire.
  4. Dub a substantial orange Antron body from bend to the 2/3 mark.
  5. Wind the palmered hackle forward in even spirals; secure and trim.
  6. Counter-wrap the gold wire over the hackle to reinforce it.
  7. Stack more elk hair and tie in flat over the body as the wing, tips to the hook bend.
  8. Dub a yellow Antron thorax ahead of the wing; wind grizzly hackle over the thorax and whip finish.
