Members of this family develop as ectoparasites in the nests of other Hymenoptera; in the case of Hoplomutilla the hosts are bees in the subfamily Apinae.
Genus Hoplomutilla is in the subfamily Sphaeropthalminae, a group characterized by eyes that are spherical and very protuberant. The eyes have a smooth, uniform appearance; individual facets are essentially impossible to discern (Brothers, in Hanson and Gauld, eds., 2006).
Members of the genus Hoplomutilla are found from Nicaragua to northern Argentina.
