The Solitude Hexagenia Foam is a dry fly pattern designed to imitate the Hexagenia mayfly, which is a large and important food source for trout. This fly is particularly effective during the Hexagenia hatch, which typically occurs in late spring and early summer. The foam body helps the fly float well on the water surface, making it an excellent choice for dry fly fishing. This pattern is known for its realistic appearance and durability, making it a favorite among anglers targeting large trout. Its available in various sizes to match the natural insects found in different waters.
