Biology

Most species are hyperparasites of Aphididae or of other plant sucking Hemiptera (Coccoidea, Psylloidea) through their Braconidae (Ichneumonoidea) or Aphelinidae and Encyrtidae (Chalcidoidea) primary parasitoids, or are primary parasitoids or hyperparasitoids of the predators of these plant pests (Diptera: Syrphidae, Chamaemyiidae; Coleoptera: Coccinellidae; Neuroptera: Chrysopidae). Some species are also recorded as pupal parasitoids of mining or gall forming Diptera (Agromyzidae, Chloropidae, Cecidomyiidae) or as egg parasitoids of several families of Lepidoptera (apparently as hyperparasitoids), and there are rare records from other families of Diptera, Hymenoptera and Coleoptera (Gibson, 2001; Noyes, 2014).
