Gerridae, commonly known as water striders, are a family of insects that are well adapted to living on the surface of water. They possess long legs that allow them to walk or glide on the water's surface, utilizing surface tension to support their weight. These insects are often found in ponds, lakes, and slow-moving streams. Water striders primarily feed on small insects that fall onto the water's surface. They are known for their quick movements and ability to jump, which helps them evade predators. Gerridae play a role in the aquatic ecosystem by controlling insect populations and serving as prey for larger animals, such as frogs and birds.
