CDC Caddis Emerger · Wet fly

A dark shape rising through evening water

A slim black CDC caddis emerger on a size 14 hook, with a silver wire rib and soft black hackle, for trout taking caddis in the film.

A dark caddis emerger with a slim curved body, a smoky swept-back wing and a sparse collar of soft fibres. It is tied in black thread and black CDC, with a fine silver wire rib banding the body.

On the water

A soft-hackle wet fly swinging through mid-water

Black from tail to head. A thin silver wire wraps the curved thread body in neat bands, and a plume of black CDC sweeps back past the bend. A few long, soft hackle fibres splay out underneath like legs still kicking free.

Fish it when caddis start popping off riffles and runs near dusk. Swing it across and down, let it rise at the end of the drift, or dress the wing lightly and let it hang in the film. Small twitches make the CDC breathe.

Black CDC needs a light touch. Tie in a small bunch, keep it sparse, and never douse it in liquid floatant; the fibres should stay soft and full of air.

  • Use 5X or 6X tippet to let the fly sit and move naturally.
  • Swing it down and across, then let it lift at the end of the drift.
  • For film fishing, treat the wing with a dry powder only.

How to tie it

The steps, from first wrap to whip finish (10)
  1. Mount the hook in the vise and start the black thread one eye-length behind the eye.
  2. Wrap a thin, even thread base back to the start of the bend.
  3. Tie in the silver fine wire at the bend and bind it along the shank.
  4. Build a slim, tapered black thread body forward to about 70 percent of the shank.
  5. Wind the wire forward in five or six evenly spaced open turns, tie off and trim.
  6. Tie in a small bunch of black CDC on top, reaching just past the hook bend.
  7. Trim the CDC butts and cover them with a few neat thread wraps.
  8. Tie in a black hen feather by the tip and take two sparse turns in front of the wing.
  9. Tie off the hackle, trim the waste and sweep the fibres back.
  10. Form a small, tidy black thread head, whip finish and trim.
Proportions (4)
  • Body: slim and tapered, covering the rear 70 percent of the shank.
  • Wing: CDC tips reach just past the hook bend.
  • Hackle: fibres about one and a half times the hook gap, sloping back toward the point.
  • Rib: five or six evenly spaced turns.
Tips (4)
  • Keep the thread flat while building the body so the taper stays smooth.
  • Wind the wire opposite to the body thread to lock it in place.
  • Stroke the CDC back before tying in so the fibres sit together.
  • Two turns of hen hackle are enough; sparse moves better in current.
Common mistakes (4)
  • Bulky body: use fewer thread layers and keep the taper thin.
  • Crowded eye: leave room behind the eye before adding the wing and hackle.
  • Overdressed CDC wing: one small bunch is plenty.
  • Uneven rib: mark spacing with your eye before the first turn.
