Bengalia
Bengalia is a genus of blow flies in the family Calliphoridae with one authority considering the genus to belong to a separate family Bengaliidae. These bristly and, unlike the greens and blues of most calliphorids, dull coloured flies, are especially noted for their relationship to ants. Little is known of their biology and life-cycle, although adults of many species are kleptoparasitic on ants and will snatch food and pupae being carried by ants or feed on winged termites.
