Ripple Bugs

Ripple bugs are a type of water strider capable of moving at a blazing fast 120 body lengths per second across the water surface. In addition to their speed, ripple bugs are incredibly agile and are active almost constantly. Researchers believe they’ve found the insect’s secret: feather-like hydrophilic fans that spread on contact with the water. These fans help the insects push off the water and steer, but they require no effort to open and close. They’ve even adapted the technique to bio-inspired robots and seen improvements in speed, agility, and efficiency. (Video credit: Science; research credit: V. Ortega-Jimenez et al.)
