Adult whiteflies are small insects, approximately 1/16th inch (1.5 mm) in length, with four powdery white wings. When heavily infested plants are disturbed, one may notice a ―cloud of tiny white insects rising above it. The immature stages (eggs, crawlers, scales and pupae) are all yellowish and found primarily on the undersides of leaves.
Whitefly adults resemble tiny moths with two pairs of wings. The wings are mealy-white (except for the citrus blackfly) and cover the body in a sloping roof-like manner.

Early instars of young whiteflies (nymphs) resemble the immature stages of soft scale insects. They are usually flat, oval, transparent, 1 to 3 mm long and lack legs or antennae. Nymphs are active only during the first instar (crawlers), becoming sessile for the rest of the nymphal instars.

Whitefly eggs are oval- to sausage-shaped and can be either light or dark brown.
