But there’s one animal that has more to fear than us: honeybees. While murder hornets don’t often attack people, they do intentionally go after honeybees. Arizona State University via YouTube (Creative Commons)

Some honeybee species in Asia, where the Asian giant hornet is native, have adopted unique defense mechanisms.

It seems to work as an alarm signal to mobilize the colony and activate its defenses. The researchers saw increased activity in worker bees once the sounds started.
