CDC Blue-Winged Olive

A CDC-winged BWO that rides perfectly in the surface film with no floatant needed. The natural oils in CDC feathers keep the fly sitting at the exact surface level where trout expect to see emerging Baetis — neither on top nor below the film.

How to Fish It

Never apply floatant to CDC — it destroys the natural oils. Dry the fly by false casting between fish. Replace after 3-4 fish.
