How do strider insects walk on water?
Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.Do water scorpions bite?

Do water striders jump?
Water striders are water-walking insects that can jump upwards from the water surface. Quick jumps allow striders to avoid sudden dangers such as predators’ attacks, and therefore their jumping is expected to be shaped by natural selection for optimal performance.
