The sphecid wasp tribe Cercerini is comprised of the genera Cerceris and Eucerceris, the former being widely distributed and the latter restricted to North America All species of Eucerceris for which prey records have been determined utilize snout beetles or weevils (Curculionidae) to feed the young. In North America, known prey records for Cerceris include members of the beetle families Buprestidae, Tenebrionidae, Chrysome- lidae, Bruchidae, and Curculionidae. Some European members of the genus have been
reported to provision the nests with other hymenopterans (e.g. solitary bees of the families Halictidae and Andrenidae) in addition to beetles.
