Water striders are insects known for their ability to walk on the surface of water. They belong to the family Gerridae and are commonly found on ponds, lakes, and slow-moving streams. Their long legs distribute their weight, allowing them to take advantage of the water's surface tension. These insects primarily feed on small insects that fall onto the water's surface. Using their front legs, they can quickly capture prey. Water striders are also known for their unique mating behaviors, which often involve elaborate courtship displays on the water's surface.
