Living habits 1 generation, wintering on branches with fertilized females. Hunchun continued to injure, and lay eggs in the body in June. The egg period is about 1 week. During the nymphal period of 80 to 90 days, the females were debrided into adult dermis three times and the males were deprived of the previous epidermis twice. The larvae were then debrided, and the eclosion period was similar to that of the females. After mating, the males died. The females continued to infest until the winter. The newly hatched nymphs were more likely than the spurs on the branches, and were more likely to colonize on both sides of the main vein on the leaves. The natural enemies are Japanese wax.
