Backswimmers are aquatic insects belonging to the family Notonectidae. They are known for their unique swimming style, which involves moving upside down on the water's surface. These insects have a streamlined body and long, oar-like hind legs that help them glide through the water with ease. Backswimmers are typically found in freshwater habitats like ponds and lakes. They are predators, feeding on small insects and other aquatic creatures. Their ability to trap air bubbles under their bodies allows them to stay submerged for longer periods while hunting for food.
