Japanese Honeybees
Japanese honeybees utterly decimate hornets.
Hornets are a major threat for bees. A hornet can easily kill 40 bees within a minute.
Since a Japanese honeybee's stinger can't pierce a hornet's outer skin, they have to resort to other ... less pleasant ways of killing it.
First they swarm a hornet and trap it inside a ball of bees. Next they start vibrating and generating extreme heat (~115 degrees Fahrenheit) and casually cook the hornet alive.
