On slower-moving water, especially in backeddies and slick runs, baetis duns emerge and dry their wings on the surface. While there, they are extremely vulnerable and a favorite target of feeding trout. The Pino BWO Wine Fly perfectly matches this stage in their life cycle. A slender profile helps it ride low in the film, and a small parachute increases visibility. Selective trout can't tell the difference between it and the real thing. Sizes: 16, 18, 20.
