FAMILY CURCULIONIDAE

SUBFAMILY MOLYTINAE

TRIBE BAGOINI

Most species of the curculionid tribe Bagoini are associated with aquatic or semi-aquatic plants that grow floating on, submerged in, or emergent from water. The adults feed and mate on the emergent portions of water-plants and the larvae feed on submerged leaves and stems. The subfamily has a wide distribution with lots of species in the Asian and Australasian region ( O’Brien et al., 1994; Caldara & O’Brien, 1995).
