By sensing how quickly their destination 'zooms in' as they fly towards it, honeybees can control their speed for a perfect touchdown, without needing to know how fast they're flying or how far away the destination is. The discovery could lead to cheaper, lighter robot aircrafts that only need a video camera to land safely. Humans find out their distance from an object using stereovision, but insects can't do the same thing because of their close-set eyes.
