Surface tension is the force that causes liquids to form drops and beads. It is caused by the attraction between water molecules. When an insect's leg touches the water, the water molecules are attracted to the leg and form a thin layer around it. This layer of water supports the insect's weight, allowing it to walk on the surface.
Insects also have special structures on their legs that help them to walk on water. These structures include tiny hairs and bristles that increase the surface area of the leg, which helps to distribute the insect's weight more evenly. Additionally, some insects have claws or hooks on their legs that help them to grip the water's surface.
By combining surface tension and the special structures of their legs, insects are able to walk on water.
