So what is the difference between a wasp and a bee? How can you tell a wasp from a bee?

Usually just by looking at them. Wasps are different from bees because they have pointed (instead of rounded) lower abdomens and a much narrower waist than bees have.

Wasps come in every colour imaginable - although they can be classic yellow/black/brown, they are also metallic blue and bright red.

Do all wasps build nests? Yes. Their nests are different from the bees, which produce a waxy substance to create theirs. Wasps chew scraped wood fibres and create more papery nests for themselves... in fact humans copied wasps' nests to make paper!
