en.wikipedia.org/wiki/Whitefly
Aleyrodidae are small insects, most species with a wingspan of less than 3 mm and a body length of 1 mm to 2 mm. The eggs of Aleyrodidae generally are laid near each other on the food plant, usually on a leaf, in spiral patterns or arcs, sometimes in parallel arcs. There generally are four larval instars. All the instars are more or less in the shape of a flattened ellipse fringed with bristles and waxy filaments. The first instar has functional legs, though short. Once it has inserted its stylets into the phloem to feed, it settles down and no longer uses its legs, and they degenerate after the first ecdysis. From then until it emerges as an adult, it remains attached to the plant by its mouthparts. The final instar feeds for a while, then undergoes changes within its skin, ceasing feeding and growing a new skin, forming what amounts to pupa. In warm or tropical climates and especially in greenhouses, whiteflies present major problems in crop protection.
