A scale insect that feeds on more than 80 families of woody plants, most notably on Citrus.

Males are rare in hermaphroditic species of Icerya. Females have an ovitestis that is capable of producing both sperm and oocytes which fertilize internally to produce diploid offspring (females) through a form of hermaphroditism. The cells of the ovitestis are haploid and are derived from excess sperm during matings with males. This has been termed as 'parasitic tissue' and theoretical studies have examined this as a form of sexual conflict.
