It’s called the RoboBee. It weighs less than a tenth of a gram and is half the length of a paperclip. The translucent, individually controlled wings become invisible as they flap 120 times per second.

According to researchers at the Wyss Institute at Harvard, when their RoboBee nano-drone eventually flies out of the lab, it has the potential to work in a swarm, just like the insect that inspired it, pollinating crops and completing a range of other useful tasks.
