Fun facts

Its nest is made of paper and shaped like a giant egg, at least 50 centimetres long.

2

It often builds a first nest low in a bush and later moves to a new nest high up in a tree.

3

In Asia the honeybees fight back: they squeeze around a hornet in a ball and shiver until it gets too hot for the hornet.

4

Each hunting hornet guards its own little patch of air in front of the hive and chases other hornets away.
