Blue-Winged Olive (BWO)Finatics Fly Company When trout start sipping like they’re at afternoon tea, it’s time to break out the Blue-Winged Olive.

Whether you’re matching a full hatch or prospecting on a cloudy afternoon, the Blue-Winged Olive belongs on your leader. Why it earns its keep: Realistic BWO mayfly profile with high float performance Olive body and gray wing match Baetis duns to a T Upright hackle keeps it floating in slow slicks and light chop Tied on a strong barbed hook for reliable hooksets One of the most important dry flies in the world, period Sizes available as variantsFinatics Fly Company
