A wasp is any insect that is neither a bee nor an ant.
The nest starts off in the spring with the queen building a petiole (a single stalk from which the nest hangs) and a single hexagonal shaped cell at the end of the petiole, then approx six more cells are formed around the centre one.
The queen will lay eggs in each cell as it is being constructed. Once these eggs have hatched out and gone through the developments stages and pupated into adult wasps, these new worker wasps take over nest construction and leave the queen solely to lay eggs and control the nest, this from now on is her primary function!
