There's no denying that spawning season draws the attention of big trout, and the Glo Bug is one of the most effective patterns during this time. Designed to imitate fish eggs, it's a buoyant and highly visible fly that excels when fish are actively spawning or feeding on loose eggs. Fished near the bottom in a nymph rig or as part of an egg-and-bug combo, the Glo Bug is a proven producer in both rivers and stillwaters.
