Bengalia is a genus of blow flies in the familyCalliphoridae with one authority considering the genus to belong to a separate family Bengaliidae.[3] 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.[4][5][6]
The apt name “Highwayman Fly” was given by an early observer of their way of robbing ants.[6]
Very little is known about their breeding habits. The genus is found in the Afrotropical and oriental region with one species from Australia possibly a recent introduction.
