Whiteflies

Minute insects, with body and wings coated with a white, waxy powder. The wings are held flat or slightly sloped over the back. When an infested bush or tree is shaken the insects may swarm out in a cloud, then rapidly settle down again. Upon hatching, the young, called a larva, crawls a short distance and settles down to feed. At the first molt it loses legs and antennae and becomes a flat, scale-like creature, often with a fringe of waxy filaments. The larvae produce copious honeydew, which is ejected from a conspicuous opening on the upper surface of the body-the vasiform orifice.
