Beetles' sticky legs aid aquatic sex

11 June 2014 Last updated at 12:27 BST

Scientists from National Chung Hsing University in Taiwan have revealed how a diving beetle hangs on to its mate underwater.

Micro-scale footage has revealed how bristles on male beetles' legs attach to females with tiny suckers.

As well as shedding light on evolution at the very small scale, understanding this could inspire the design of devices for underwater attachment in engineering.

This video, shot by the researchers, shows exactly how the beetles' remarkably evolved legs stick to a female's body.
