The adult female is wingless, legless (sedentary form) and has a broadly reniform, brownish-red scale-like cover, 1,5-2,0mm, firmly attached to the surface. They give birth to mobile nymphs (crawlers)that they move around the plant until the next developmental stage in which they become sedentary. The adult male is winged and it doesn’t feed on the plant. Its only purpose is to mate.
