Water boatmen are small aquatic insects belonging to the family Corixidae. They are commonly found in freshwater habitats like ponds, lakes, and marshes. These insects are known for their distinctive oval shape and long, paddle-like hind legs, which they use to swim efficiently. Water boatmen primarily feed on algae and decaying plant material. These insects are often mistaken for backswimmers, but they differ in behavior and appearance. Water boatmen are typically found swimming on the water's surface, where they can be seen propelling themselves with their legs. They play an important role in the ecosystem by helping to break down organic matter and serving as food for various predators.
