Plants growing close to buildings seem to be damaged more than those growing where there is free air circulation. The scales overwinter as fully grown, fertilized females. Eggs are deposited under the female scale in the early spring. They soon settle and begin to feed. There are three more generations during July, August, and September.
Male scales are elongate, tiny and chalky white in color with the exuviae at one end.
As usual with armored scales, the actual body of the female is yellowish and sac-like with well developed mouthparts but without legs, eyes, or antennae. The adult male is a small, gnat-like insect. Ornamental and Lawn Pest Control .
