White Peach Scale

Identification and life cycle

White peach scale is an armored scale, with the insect sheltered under a waxy cover rather than exposed like an aphid. Adult males and females differ markedly, and mobile young crawlers are important for establishing new feeding sites. Its host range and generation timing vary with conditions. The presence of a white scale on a plant is not sufficient for identification; microscopic examination may be needed to separate similar species.
