Quick Summary

Solitary wasps are insects that, unlike social wasps, do not live in colonies. The vast majority of wasp species are solitary. These wasps typically build individual nests or cells, provisioning them with paralyzed insects or spiders to feed their developing larvae.123

Nesting habits vary: some dig tunnels in the soil, others use woody stems, and some construct nests from mud. Examples include mud daubers, spider wasps, and potter wasps. A significant portion of solitary wasps are parasitic, laying their eggs in or on the larvae or pupae of other insects.32
