After they find a preferred feeding site they attach to the underside of the leaf and begin feeding. These stages become flattened on the leaf surface and are very difficult to see because of their transparent green color. Except for size the last two nymphal stages are similar in appearance. Nymphal development is completed in 9-17 days. The development of the first nymphal stage is completed in 3-5 days.
Larval duration varies with temperature and host.
Duration of the life cycle is increased with cooler temperatures. The body of this nymphal stage is thicker than other stages and posses characteristic long wax filaments along the outer margin. The duration of the pupal stage is 3-7 days. At rest, wings are held flat. Adults generally live for 21-40 days.
