As they feed, they secrete honeydew melon and a waxy coating begins to create over their bodies. Feminine nymphs labor fewer than 3 stages (instars) with a generation taking as very little united month, counting on temperature. Male nymphs labor fewer than 5 instars. They are doing not feed once the primary 2 instars and exist only to fertilize the females. Within the greenhouse, continuous and overlapping generations occur throughout the year.
