On the water

A dry fly riding the surface of a trout river

Orange floss glows under thin brown bands, and the wing stands up like a small flame. Long barred tail fibers fan out behind, speckled gold and rust against the grey slate.

Fish it on the soft glides and flat pools when sulphurs start coming off near dusk. Cast above the rise, let it drift without drag, and keep the line off the fish's window.

CDC is the part to treat with care. Pinch in a few feathers for the wing, keep floatant paste off it, and dry it with a powder so the fibers stay airy.

Rigging

Tippet
5Xhook size divided by three
Leader
Nine feet, tapered — longer and finer in flat water
  • Rig on 9 to 12 feet of leader tapering to 6X tippet for flat, clear water.
  • Present it downstream with a reach cast so the fly reaches the fish before the tippet.
  • Dry the CDC with powder between fish rather than paste floatant.

How to tie it

The steps, from first wrap to whip finish (11)
  1. Mount the hook and start the orange thread behind the eye, wrapping a thin base to the bend.
  2. Build a tiny thread bump at the bend, then tie in coq de leon fibers on each side so they split around it, about one shank length long.
  3. Tie in the brown rib thread at the bend and let it hang.
  4. Tie in the orange floss and wrap a smooth, slightly tapered body over the rear two thirds of the shank.
  5. Spiral the brown rib forward in five or six even turns and tie it off.
  6. Stack two or three orange CDC feathers, tie them in upright at the two-thirds point, wing height about one shank length.
  7. Prop the wing upright with a few thread wraps in front of it.
  8. Tie in the orange rooster hackle by the stem, shiny side forward, fibers about one and a half times the hook gap.
  9. Dub a small orange thorax around the base of the wing.
  10. Wrap the hackle three or four turns through the thorax and tie it off behind the eye.
  11. Form a small neat orange head, whip finish and trim the thread.
Proportions (5)
  • Tail: split fibers about one shank length, fanned at a slight angle.
  • Body: floss and rib cover the rear two thirds of the shank.
  • Wing: CDC height roughly equal to the shank length.
  • Hackle: fibers about one and a half times the hook gap.
  • Thorax: a small ball, no wider than the body's thickest point.
Tips (4)
  • Flatten the floss by untwisting the bobbin so the body lies smooth and glossy.
  • Keep the rib wraps evenly spaced for clean segmentation.
  • Use only three or four hackle turns so the fly sits low on the film.
  • Moisten your fingers slightly to gather CDC fibers into a tidy bunch.
Common mistakes (4)
  • Tail fibers bunched together: use a firm thread bump at the bend to split them evenly.
  • Lumpy floss body: wrap thin layers and keep tension steady.
  • Wing leaning back: add a few figure-eight wraps in front to stand it up.
  • Crowded eye: leave a hook-eye width bare before wrapping the hackle.
