Which insect can run on water?
The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water bugs, pond skaters, water skippers, or Jesus bugs. Consistent with the classification of the Gerridae as true bugs, gerrids have mouthparts evolved for piercing and sucking, and distinguish themselves by having the unusual ability to walk on water, making them pleuston (surface-living) animals.
They are anatomically built to transfer their weight to be able to run on top of the water's surface. As a result, one could likely find water striders present in any pond, river, or lake. Over 1,700 species of gerrids have been described, 10% of them being marine.
