Fun facts
It makes its nest out of paper. The paper comes from wood that the wasps chew up.
A nest can be 12 to 23 centimetres wide and hangs 1 to 5 metres above the ground.
A queen starts the nest all by herself in spring and raises the first 10 workers alone.
A whole nest lasts only about three months, from May to the end of August.
It first reached Britain in 1980.
