As the female lays eggs, its body shrivels gradually. A until the egg sac is almost completely filled with eggs. Eggs are laid in late April. They hatch in about 3 weeks. This new generation matures during the summer and produces eggs in September.
Mature females tend to feed in crotches and on twigs.
Adult males, two-winged and tiny, tend to feed on the leaves. Azalea bard scales overwinter as nymphs feeding on the bark. The key to control is treatment in late spring and late fall when the nymphs are present. For specific controls, see the current state extension service recommendations.
