Monophlebidae - (giant scale insects)
This family was previously considered to be a subfamily of the Margarodidae. In contrast to the root-feeding Margarodidae sensu stricto, the Monophlebidae feed on leaves and branches. Economically, the genus Icerya and the Australian fluted scale, Icerya purchasi are most important. That genus is common in the tropics and subtropics, infesting citrus and other crops.
The species have an elongated oval body, usually covered with wax, and grow up to to a length of 10 mm. The adult females have six legs and well developed antennae. There are 4 female and 5 male instars and the prepupae are mobile.
The following genera and individual species are currently entered under this family:
