Tiny beetle filmed walking on the underside of the surface of water

 A pair of researchers from the University of Newcastle and the German Center for Integrative Biodiversity Research has documented a water scavenger beetle walking on the undersurface of a body of water. In their paper published in the journal Ethology, John Gould and Jose Valdez describe the beetle and suggest some theories to explain the unique behavior.

The find was made by Gould in Callaghan, Australia. At first, he thought the beetle was swimming across the surface—but a closer look showed the bug was not only upside down and submerged, but was using the surface as a means of transport.

Intrigued, he captured the action on video and showed it to his colleague, Valdez. The two then scoured the literature for similar finds, but found very little.

After closely watching the video, the researchers discovered how the beetle was able to achieve its unique feat. First, it had placed a bubble along its abdomen that appeared to help with buoyancy. With each step, the beetle's foot pushed a small amount of water above surface level, giving it traction.
