The Sapygidae are a family of solitary aculeate wasps. They are generally black wasps, similar in appearance to some Tiphiidae, with white or yellow markings developed to various degrees. The female oviposits her eggs into the nests of solitary bees, and the developing larvae consume both the host larvae and the supply of food provided for them. Fossil sapygids have been found in Upper Eocene Baltic amber (Brischke, 1886).
