Now this is something I found pretty interesting; biologists found out that bees use a time-to-contact strategy when planning their landing. ESA’s Advanced Concept Team already summed up all relevant information, so I’ll give just the appropriate citations for further reading. Bonus: ACT implemented this strategy in a Parrot AR drone!
