Blue Wing Olive

The Blue Wing Olive is a highly effective dry fly that mimics the small mayflies common in colder months and spring hatches. Its natural olive and blue-gray coloration make it a perfect match for BWOs, which trout eagerly feed on in both stillwater and rivers. This fly is especially productive in clear waters when fish are keying in on emerging insects. A must-have pattern for anglers targeting trout during mayfly hatches.
