CDC Elk Hair Caddis

The CDC Elk Hair Caddis is a versatile and highly effective dry‑fly pattern designed to imitate an adult caddis skittering or drifting on the surface. “CDC” refers to cul de canard—French for “duck’s bottom”—the naturally buoyant feathers used to give the fly its soft, lifelike wing and exceptional floatability. Paired with a traditional elk‑hair overwing, the pattern blends realism with durability and visibility.
This fly shines in rivers and streams during active caddis hatches, especially in the late afternoon and evening when adults are most active. Target rising fish or drift it through riffles and runs where trout are keyed in on surface insects. With its subtle profile and buoyant materials, the CDC Elk Hair Caddis remains a dependable choice whenever caddis are on the menu.
