Researchers in the UK and the US have beenawarded a grantto build microrobots that simulate the buzzing of bees.
The tiny robots are the size of a fingernail and weigh a quarter of a honeybee.
Gaining a better understanding of which flying critters buzz best and how they do it could improve agriculture.

One out of every three bites of healthy food we eat is pollinated by honey bees and other pollinators.
