Gericidae

Gericidae is a family of true bugs belonging to the order Hemiptera. This family is commonly known as freshwater water striders. They are characterized by their slender bodies and long legs, which allow them to walk on the surface of water. Gericidae are found in freshwater habitats worldwide, including ponds, lakes, streams, and marshes. Their unique ability to distribute their weight across the water's surface tension enables them to move and hunt prey.

These insects are predatory, feeding on smaller aquatic insects and other invertebrates that fall into or near the water. They detect prey through vibrations on the water surface. Their forelegs are often adapted for grasping prey. Gericidae are also known for their ability to glide across the water and sometimes even fly. The life cycle typically involves nymphs that resemble smaller versions of the adults and undergo several molts before reaching maturity. They play a role in aquatic ecosystems as both predators and prey for larger organisms.
