The CDC (Cul de Canard) fly is a highly adaptable pattern that mimics a wide range of insects, from mayflies to midges, thanks to its lifelike movement and natural buoyancy. Tied on a standard dry fly hook, its slender body—crafted with dubbing, thread, or floss—can be customized in color to match local hatches. The tail, made from hackle fibers or CDC, enhances realism, while the signature CDC feathers, sourced from duck preen glands, provide unmatched floatation and lifelike motion on the water’s surface.

Tying techniques vary—split-thread, dubbing loops, or direct attachment—but the key is keeping the CDC sparse to maximize its natural properties. This fly excels in all freshwater environments, making it a go-to for anglers who observe and adapt to local insect activity. Whether targeting selective trout or experimenting with presentations, the CDC fly’s versatility ensures success across diverse fishing conditions.
