00:04When giant cousins of murder hornets attack Asian honeybees, the bees raise an alarm similar to
00:11the panicked calls of birds and mammals. Giant hornets are a sister species, two so-called murder
00:18hornets. They're one of the deadliest predators of Asian honeybees, attacking in groups until
00:23they overwhelm a colony. Scientists recently recorded and analyzed alarm sounds made by
00:28honeybees during hornet attacks.
00:40They found that when a giant hornet shows up, the bees made a lot more noise.
01:16Giant hornets are the biggest threat to Asian honeybees. Just one attack can wipe out an entire colony.
01:22This could explain why bees have evolved to have a special signal for a giant hornet attack.
