Why do wasps build thier nest?

If a wasp plants thier eggs on catepillars and spiders, what is the purpose of those nests that they build.

Why do wasps build thier nest?
Insects will instinctively build pupation chambers. The honeycombs of bee hives serve the same purpose. These nests are intended to protect the developing insect from the elements. These pupal chambers also reduce the chances of being found by predators such as ants, spiders and other wasps/hornets. The main purpose is camouflage, most wasps form these chambers underground, where they are seldom found from predators. The potter and papaer wasps that do this try to get the nests off the ground where most of their predators occur more frequently.

It is mostly maternal protection instinct that drives the formation of these chambers.

I hope that answers your question!
Reply:Some species of solitary wasp lay their eggs on caterpillars or other host species which provide food for the wasp larvae when they hatch. Usually the wasp stings the host animal to paralyse it and often then buries it in some way so that other predators don't eat the host and the wasp eggs.



More advanced species of wasp live in colonies and build nests out of "paper" made by chewing wood and mixing it with saliva and forming it into a nest. This is used to store food, again usually caterpillars or other similar prey, and to protect the eggs and larvae during development.
