Japanese honey bees have been captured using a new technique called “wing-slapping” to protect their hives from intruding ants.
Bees have long used the flapping force of their wings as a defence mechanism that literally blows ants away.

But the Japanese variety of honey bees have displayed an entirely new, never before recorded, behaviour.
The behaviour was captured by Yugo Seko, Kiyohito Morii, and Yoshiko Sakamoto of the National Institute for Environmental Studies.
“I myself did not notice this behavior during my approximately 10 years of beekeeping experience,” Sakamoto told New Scientist.
The team photographed the ant-swatting with a high-speed camera, showing the bees rotating their bodies and flicking ants away with their wings.
The interaction was recorded in the video above.
The video shows three local species of ants walking towards the entrance of two Japanese honey bee colonies.
The effectiveness of their “wing-slapping” varied depending on what species of ants the bees were contending with.
Japanese queenless ants and Japanese pavement ants were fended off fairly successfully, with half to about one-third of bee whacks flinging the ants away.
Whereas “wing-slapping” Japanese wood ants, a larger and faster variety, was not as successful.
Experts believe Japanese honey bees have evolved combative measures to protect their hives – but they’re unsure why.
Morii added: “These defensive behaviours still hold many mysteries.”
Ants vs Bees
Ants can pose a significant threat to bee hives.
They are always looking for a warm, safe place to lay larvae and have a steady source of food – and bee hives are an ideal place for that.
While they may vary in their level of menace, some ant species can bite or even kill worker bees.
They also eat bee larvae and can quickly take over entire hives, which may push a weak bee colony to collapse.
That is, if the bees are unable to fight off an invasion.
Bees have evolved a fanning defence mechanism that can blow away ants.
But the newly discovered “wing-slapping” method may be a more efficient option, researchers have suggested.
