The sting of yellowjackets, or paper wasps, can be a potential health threat to people who are allergic to the venom. Wasp species are categorized into two groups; as either social or solitary.
Social wasps live in colonies amongst potentially thousands of other wasps. Within these social colonies it is the female workers who perform all duties within the nest. Solitary wasps on the other hand live alone and do not have a colony. Once they have laid their eggs, the eggs are left alone to hatch.
