Giant hornet (<italic toggle="yes">Vespa soror</italic>) attacks trigger frenetic antipredator signalling in honeybee (<italic toggle="yes">Apis cerana</italic>) colonies

Asian honeybees use an impressive array of strategies to protect nests from hornet attacks, although little is understood about how antipredator signals coordinate defences. We compared vibroacoustic signalling and defensive responses of Apis cerana colonies that were attacked by either the group-hu...
