BWO Emerger Fly Pattern
Blue-winged olive emergers are an important fly pattern to have available during mayfly activity on the Truckee River and other western trout streams. Trout often key in on insects transitioning just below or within the surface film.
This video takes a closer look at a BWO emerger fly pattern and why emerger-style flies can be so effective during spring and fall hatches when fish become selective.
Whether fished alone, behind a dry fly or as part of a technical presentation, BWO emergers remain an important part of many Truckee River fly boxes throughout the year.

- How this style of fly fits into a spring or fall dry-dropper setup
Why BWO Emergers Matter
During a blue-winged olive hatch, trout may feed heavily on insects that are emerging just under or in the surface film. When fish refuse high-floating dry flies, an emerger pattern can often be the better choice.
