Honey bees ....
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.

Humans find out their distance from an object using stereovision, but insects can't do the same thing because of their close-set eyes.
