The Torymidae are a family of wasps that consists of attractive metallic species with enlarged hind legs, and generally with long ovipositors in the females. Many are parasitoids on gall-forming insects, and some are phytophagous (plant-eating) species, sometimes usurping the galls formed by other insects. Over 960 species in about 70 genera are found worldwide. They are best recognized in that they are one of the few groups of Chalcidoidea in which the cerci are visible.
