Jumping by Water Striders (video) Laboratory of Behavioral Ecology and Evolution at Seoul National University Share Print E-Mail Loading video... Caption The video clip shows a slow motion of a water strider jumping upwards. Note the "dimples" under the legs and how they increase in depth while the legs push down and "bend" the water surface without breaking it. The model focuses on this ability of insects to jump upward without breaking of the water surface. It shows that this ability results in maximization of the jump speed and minimization of the latency between the jump initiation and leaving the water surface in the response to attacking predators.
