The March Brown is a classic mayfly imitation, essential for early-season trout fishing. Designed to match the natural hatches of March Brown mayflies (Maccaffertium vicarium), this fly is particularly effective in late winter and early spring when these large, slow-emerging insects become a primary food source for trout. Its natural brown and tan coloration, combined with a lifelike profile, makes it an excellent choice for fooling selective fish in a variety of water conditions.

Tied with high-quality materials, the March Brown sits naturally on the waters surface, closely resembling a freshly emerged mayfly. It is most effective when trout are actively rising during a hatch, making it a staple in any anglers fly box for early-season fishing.

To fish the March Brown effectively, present it as a dry fly with a drag-free drift, allowing it to float naturally with the current. Target riffles, seams, and slow-moving pools where trout are feeding on emerging mayflies. For best results, apply a light coat of floatant to keep the fly riding high on the surface.
