Hosts have been recorded for relatively few of the known species. However, several species,
in North America and elsewhere, have been reared from the puparia of Syrphidae, others from
the puparia of Tachinidae; and an African species has been recorded repeatedly from the pu-
paria of the tsetse fly, Glo.ssitia palpalis Rob.-Desv. A number of other species have been found
in the nests of ants where they presumably developed as parasites of myrmecophilous Diptera.

Species of this genus are most commonly associated with sternorrhynchous Homoptera, espe-
cially aphids and mealybugs, and to a lesser extent chermids and psyllids. They usually develop
either as hyperparasites through other Hymenoptera that are primary parasites, or as parasites
of predatory larvae such as those of Syrphidae (various genera) and Chamaemyiidae (especially
Leiicopis and Cre))iaHifa)ii(i). Other recorded hosts include species of Coniopterygidae,
Hemerobiidae and the phytophagous dipterous genera Mayetiola and Meroinyza.
