This artificial fly, designed to imitate emerging insects, presents a buoyant profile on the water’s surface. Its construction typically incorporates buoyant materials and prominent hackle, allowing it to float high while still presenting a partially submerged appearance. For example, a size 14 with a foam body and CDC wing can effectively mimic a mayfly struggling to hatch.
Its utility stems from its effectiveness in imitating a wide range of aquatic insects during their vulnerable transition to adulthood. This broad applicability makes it a valuable addition to any fly fisher’s arsenal. The design, gaining popularity in recent decades, bridges the gap between traditional dry flies and emerger patterns, offering increased visibility and floatation.
