Blue Wing Olive (BWO) Dry Fly

The Blue Wing Olive Dry Fly is a must-have pattern for matching one of trout fishing’s most frequent hatches – the tiny olive mayflies known as BWOs. Its olive body and subtle gray-blue wing closely imitate the “Baetis” mayflies that trout sip on cloudy days and in cooler seasons. This delicate fly excels on clear streams and tailwaters; beginners can use it to fish any blue-winged olive hatch, and seasoned anglers confidently rely on it when picky trout are feeding on small dries. Presented with a gentle drift, the BWO Dry Fly consistently fools trout feeding on naturals, making it essential for spring and fall fly fishing when these little mayflies abound.
