Plants tend to outgrow the injury by midsummer. Nymphs hatch from eggs in the spring. They produce a white, waxy material that often covers their bodies. As they feed, the leaves curl upward which helps hide and protect the nymphs. After further development during the spring, adults are formed.
Adults also feed on boxwood, but are less damaging than nymphs are.
Adult females lay eggs under bud scales. The immature nymphs develop within the eggs, where they remain until spring. They emerge in spring to feed and complete development to adults. Only one generation occurs per year.
