Appearance
Adults are 1–2 mm in length, with yellowish bodies and four wax-coated wings held near parallel to the leaf surface.
Behavior
Females are capable of mating less than 24 hours after emergence and most frequently lay their eggs on the undersides of leaves. Eggs are pale yellow in colour, before turning grey prior to hatching. Newly hatched larvae, often known as crawlers, are the only mobile immature life-stage. During the first and second larval instars, the appearance is that of a pale yellow/translucent, flat scale which can be difficult to distinguish with the naked eye. During the fourth and final immature life-stage referred to as the "pupa", compound eyes and other body tissues become visible as the larvae thicken and rise from the leaf-surface. However, this stage cannot be defined as a true pupa stage as hemipterans do not exude this stage of development.References:
