Some insects and animals can walk on water, and that’s spiders, lizards, ants, and snails. Scavenger Beetles can also walk on water, but they can also do more tricks than just walk. They’re remarkable in that they can flip upside-down and scuttle beneath the surface of the water. It’s as if they’re climbing underneath a glass table, except that glass is water. It’s truly bizarre and is something that remains one of the most fascinating mysteries in regard to insects. To study this, scientists took a few different approaches. “In the first study to analyze this skill in-depth, researchers filmed the insects’ inverted crawling technique. These beetles trap air bubbles with their leg hairs to keep them oxygenated. But video footage shows this behavior may also keep them afloat and pinned to the surface.”
It seems like these insects are smarter than us humans. “The bubble likely gives the bug enough support to put some pressure on the water-air boundary without breaking through. The beetle’s footsteps even push up “tiny hills” of water along the surface as they go.” Even after observing these bugs, scientists still have many questions. They’re using these insects to help build bots that replicate the bug’s skills. This is just like the shark intestines and butterfly wings. It looks like scientists are turning to the natural world more and more to create an unnatural world for the use of search and rescue or military purposes (Smithsonian Mag).
