Pest description and damage Female cottony cushion scales are orange, yellow, or brown, but its most distinguishing feature is the elongated, ribbed, white cottony egg sac that is attached to its body. The egg sac contains from 600 to 800 red eggs and may be longer than the body of the female; the resulting length of the female plus the egg sac can be almost 0.5 inch. Eggs hatch into crawlers, which are red with black legs and antennae. They settle along leaf veins and produce the white cottony secretion for which they are known.
