Mealybugs are soft, oval, flat, distinctly segmented, and covered with a white, mealy wax that extends into spines (filaments) along the body margin and the posterior end. The species differ mainly in the thickness and length of the waxy filaments. Citrus mealybug, the most common species, has a pinkish body that is visible through the powdery wax. The filaments around its margins are not appreciably longer at the posterior end. The Comstock mealybug primarily occurs on lemons in the San Joaquin Valley and has a thicker wax cover than the citrus mealybug. In addition, it has two spines at the posterior end, about one-quarter the length of the body. The other two mealybug species are usually not a problem in citrus because their numbers are kept at low by parasites.
Female mealybugs lay several hundred eggs on the leaves, fruit, or twigs; eggs for some of the species are laid in cottony egg sacs. Newly hatched nymphs are light yellow and free of wax, but soon start to excrete a waxy cover. There are two to three overlapping generation a year.
Mealybugs are often found between clusters of grapefruit, especially in groves tended by ants. Due to their habit of hiding in crevices, light infestations are easily overlooked.
