BIOLOGY

This species is usually found on grasses, but frequently the adult females move onto adjacent trees to oviposit.

ECONOMIC AND CONTROL

Although this species does not appear to cause any damage, its presence under the calyxes of apples and pears grown for export has caused concern in Australia and New Zealand (see Ward, A. 1966. Mealybugs (Hemiptera: Pseudococcidae) in Hawke's Bay orchards. New Zealand Journal of Agricultural Research 9: 452–454).
