Why are insectsable to walk on the surface of dirty water?

Insects can walk on the surface of water due to a phenomenon called surface tension, which is created by the cohesion of water molecules. Their bodies are often covered with tiny hairs or structures that repel water, allowing them to distribute their weight and avoid breaking the surface tension. Additionally, some insects, like water striders, have specialized adaptations that enable them to exploit this surface tension effectively. This ability allows them to move across water without sinking.
