What is a "dry fly"?

A dry fly is a type of fishing fly designed to imitate insects that land or float on the water's surface. It is typically made with buoyant materials and does not sink, allowing anglers to fish it on or near the water's surface to attract fish that feed on insects floating on the surface. Dry flies are commonly used in fly fishing to target species such as trout and other freshwater fish that feed on surface insects. The design and appearance of dry flies vary to mimic different types of insects, making them an effective tool for enticing fish to strike.
