Distribution Predominately a northern Hemisphere group. Represented in Africa by the endemic South African monotypic genus Rhoophilus.
Biology Develop as obligate inhabitants (termed inquilines) in the galls induced by other insects.

Mostly inquilines of gall-inducing Cynipini on Fagaceae, or primary gall formers (in the case of some Synergus species). In some cases, inquilinism reaches a degree where gall inducers do not survive and hatch (Buffington et al. 2020).
