Notes: Cul-de-canard (CDC) was first marketed into the United States in 1990 by Dennis Black of Umpqua Feather Merchants. The material had been used in the Jura Mountains of Switzerland since the 1920's with Moustique patterns. Shane Stalcup was one of the early tiers to utilize this material in the United States and he adapted the CDC as a replacement for the Deer Hair wing on a Comparadun pattern in the late 1980's. The CDC dun utilizes CDC material for the wing. It can be tied in a comparadun style without a hackle due to the high floatation character of CDC. This is a progression of the No-Hackle pattern that was introduced by Swisher and Richards in the 1970's. The CDC can also be used as a wingpost with a parachute hackle surrounding the post. Rene Harrop wrote about CDC in the July issue 1991 of Fly Fisherman magazine and showed his version of a CDC Parachute Dun. The hackle provides a somewhat higher profile and will withstand faster currents. Marc Petitjean popularized many techniques for utilizing CDC and created dun patterns with split wings.
The CDC Dun can be tied in a number of sizes and colors to mimic the newly emerged mayfly. The pattern is generally simple with a tail of microfibbets or tailing fibers. The body can be tied with dubbing or quill, maintaining a slender, thin body. The CDC wing is located above the thorax position and can be tied using a number of techniques. The simplest technique is to tie two CDC plumes with the tips facing over the eye of the hook, pulling the plumes until the tips equal the length of the shank, and to trim the back half of the CDC with a taper. Another technique is to trim the fibers off two CDC Plumes and anchor these fibers to the thorax region, pulling the fibers for desired length. Two plume tips are secured in front of these fibers and secured upright for wings.
