Likewise, why can water striders walk on water biology?
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. Gerridae species use this surface tension to their advantage through their highly adapted legs and distributed weight.
In respect to this, what causes water striders to fall into the water?
Water striders are insects with six legs. That buoyant air keeps the legs from breaking the water's surface and makes the striders bob back up if they get swamped by a tiny wave. The weight of the strider pushing down on the water causes the surface to deform—but not so much that it breaks. Instead, the water dimples.
Water Striders are considered beneficial because they prey on other insects including mosquito larvae. They are medically harmless and are not known to bite. They leave a minor sting that goes away without treatment but it leaves a small red mark for several hours.
