Prey / Associated habitat

HEMIPTERA: Coccoidea: Aonidiella aurantii (Maskell), Aonidiella orientalis (Newstead), Aspidiotus destructor Signoret, Aspidiotus nerii Bouche, Aulacaspis rosarum Borchsenius, Chrysomphalus aonidum (Linnaeus) (=C. ficus Ashmead), Coccus viridis (Green), Lepidosaphes beckii (Newman), Lepidosaphes gloverii (Packard), Lepidosaphes piperis (Green), Parlatoria pergandii Comstock, Pinnaspis aspidistrae (Signoret), Pinnaspis buxi (Bouche), Pinnaspis dysoxyli (Maskell) (as Hemichionaspis minor Maskell), Pseudaulacaspis pentagona (Targioni Tozzetti), Rutherfordia major (Cockerell), Saissetia coffeae (Walker), and Unaspis citri (Comstock). Frequently associated with scale insects infesting tea, coffee, pepper, and other plantation crops, mulberry, and citrus. More common in cooler climates and plantations at high altitudes than in plains.

In Australia (Queensland), it has successfully suppressed the citrus snow scale, Unaspis citri (Comstock), to sub-economic levels in most of the orchards (Smith et al. 1995).
