Genus Gerris, commonly known as the water strider, is a species of insects that are adapted to live on the surface of water bodies. Water striders are found in various parts of the world, and are known for their distinctive ability to skim along the surface of water. They play a significant role in aquatic ecosystems, as they serve as a food source for other animals. Synonyms for the Genus Gerris include pond skater, water skipper, and water skate. These names are given to water striders due to their ability to move quickly across water surfaces, and their long, thin legs that enable them to walk on water.
