If you weren't terrified of Japanese Hornets yet, you will be after you watch this.

A group as small as 30 Japanese Giant Hornets can kill 30,000 honey bees!

The honey bees did not evolve around such a fearsome predator, so they don't have a natural defense against them, their stings are not strong enough to ward off the hornets.

The hornets can kill them at a speed of almost 40 bees a minute. In the video below you can see 30 hornets taking down a colony of 30,000 honey bees.

They did it in under 3 hours. So why do they do this? To butcher and kill the bee larvae to use as an energy source!
