An attempt has been made to analyze the contribution of the superhydrophobic coating of a water strider's legs to the insect's floating and movement on the water surface. Superhydrophobic coatings and normally hydrophobic coatings were fabricated on the gold threads to study comparatively their influence on the supporting force and motion of gold threads on a water surface. It was observed that the total supporting force provided by the normally hydrophobic coating is enough to support the water strider when it merely floats. It was also observed that superhydrophobic coating on the water strider's surface provide additional buoyancy force by wrapping its body with a thin layer of air, which allows the insect to emerge out through the water surface when it sinks and then refloat again. The superhydrophobic coating also reduced the fluidic drag during movement on the water surface allowing the water strider to move faster.
