CDC Biot Dun - Mahogany

Description

The CDC Biot Dun is a refined dry fly designed to imitate emerging or freshly hatched mayflies sitting flush in the surface film. Its body is formed from a slim, segmented turkey biot that mimics the natural taper and color of a mayfly abdomen, while the wing is crafted from CDC (Cul de Canard) feathers—renowned for their natural buoyancy, movement, and ability to trap air bubbles. The result is a highly realistic silhouette that rides low and delicately on the water, perfect for fooling selective trout in calm runs, slicks, and tailouts. Ideal for technical rivers and spring creeks, the CDC Biot Dun excels when matching specific mayfly hatches like Blue-Winged Olives, PMDs, and Hendricksons. Its blend of lifelike texture, subtle sheen, and perfect posture makes it a must-have for anglers who value precision and presentation above all else.
