It is commonly believed that the wasps are not the friendliest animals out there - but in fact wasps are rarely aggressive unless provoked. There are also a lot - a whole lot - of them, as they live in every corner of the world, except for the icy Antarctica. These buzzers make their papery nests from tree bark. They strip it from certain trees, chew it all up, add certain enzymes and regurgitate it in a pulp form to create their magnificent-looking nests.
