Blue Wing Olive Midge

The Blue-Winged Olive Midge is a smaller, simplified pattern that mimics midges or very small Baetis species—especially during hatches when trout feed on tiny, dark-bodied insects in the surface film. It features olive or gray-olive bodies and delicate wings, appealing to selective fish in spring creeks and tailwaters.

History:
This pattern blends characteristics of midge and BWO imitations, developed as anglers faced increasing pressure on technical waters. It reflects the overlap between tiny mayflies and midges in appearance, especially in sizes 20–24, and was popularized by anglers fishing tailwaters and spring creeks in the late 20th century.
