Icerya is a genus of scale insects in the family Monophlebidae. It is named after physician-naturalist Dr. Edmond Icery of British Mauritius.[1]

Hermaphroditism

Hermaphroditism is extremely rare in the insect world despite the comparatively common nature of this condition in the crustaceans. Several species of Icerya, including the pestiferous cottony-cushion scale, I. purchasi, are known to be hermaphrodites that reproduce by self-fertilising. Occasionally males are produced from unfertilised eggs, but generally individuals are monoecious with a female-like nature but possessing an ovotestis (a part-testis, part-ovary organ) and sperm is transmitted ovarially from the female to her young.[2] The existence of both hermaphrodites and males in a species is known as androdioecy. This hermaphroditic sexual self-sufficiency, where a single individual can populate new territory, has contributed to the invasive spread of the cottony-cushion scale insect away from its native Australia.[3]
