Cdc Caddis Bottom

Although I have not fished this Rene Harrop pattern, its buggy appearance and the animation supplied by the CDC feathers should make it effective. To tie, dub the body and tie the zelon in downwing style extending just beyond the bend of the hook. Match 2 CDC feathers and tie them over the zelon. Their length should be slightly longer than the underwing. Let the butts of the feathers extend over the eye of the hook. Dub in the thorax a little thicker than the body. To form the legs pull the CDC buts back until they are perpendicular to the hook shank. Secure them in place by forming a head directly in front of the stems. Trim the butts off so that they stick out a short distance from the hook. Match the wing and thorax and body color to the natural.

Hook — Mustad 94840, #12-#20
Body — Flyrite or other Synthetic dubbing
Underwing – Zelon(sparse)
Wing — 2 CDC feathers
Thorax – Same as body
