Torymidae is a family of wasps in the superfamily Chalcidoidea. Most species in this family are small with attractive metallic coloration, and females generally have long ovipositors. Many are parasitoids on gall-forming insects, and some are phytophagous (plant-eating) species, sometimes using the galls formed by other insects. Over 960 ...

Torymidae, as recognized until now, is one of the mid-sized families of Chalcidoidea that included 69 valid extant genera and about 1100 described species (Grissell, 1995; Janšta et al., 2013).

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.

Mar 25, 2025 · Most Torymidae are ectoparasitic idiobionts of various concealed hosts (e.g., gall-maker larvae, eggs of Mantodea in egg cases, larvae of Aculeata (Hymenoptera) nesting in plant stems or wood).

Bees, wasps and ants (plus sawflies) are all part of the insect order - Hymenoptera (meaning 'membrane wings'). A typical hymenopteran has 2 pairs of wings though they are coupled together with tiny hooks so appear as 1 pair.
