The giant honeybees of East Asia can build impressive open nests measuring a few meters across. The fact that they are always exposed makes them vulnerable to predators, particularly large wasps and hornets that love nothing more than invading hives and stealing grubs. Luckily, the bees have a secret weapon that is as visually mesmerizing as it is effective.
Called shimmering, the unique defensive strategy of giant honeybees involves large numbers of workers raising their rear-ends by ninety degrees and shaking them in unison, creating an effect similar to the well-known Mexican waves seen at stadiums across the world. How hundreds of bees are capable of communicating and producing this highly coordinated response to threats remains unknown, but after 15 years of studying the behavior in the wild, scientists are now convinced that shimmering is a defense mechanism.
