Wasps sometimes gather together in swarms and build enormous nests that hang on trees, under the eaves of buildings, and even in holes in the ground. Because wasps ate rather surly and irritable insects, swarms of wasps can be extremely dangerous.

Despite their maligned reputation, wasps are valuable parts of the ecosystem, since they eat an enormous amount of otherwise harmful insects.
