Spiraling whitefly Aleurodicus dispersus, copyright Sam Fraser-Smith.

Belongs within: Sternorrhyncha.
Contains: Aleyrodinae.

The Aleyrodidae, whiteflies, are small plant-sucking bugs with immobile nymphs, some species of which are notorious crop pests. Adults are soft-bodied with reduced wing venation and are usually covered with a white, waxy powder (Carver et al. 1991). The earliest fossil whiteflies are known from Early Cretaceous Lebanese amber (Grimaldi & Engel 2005).

Characters (from Grimaldi & Engel 2005): Adults usually covered with a mealy, flocculent wax, secreted by pairs of large glands on several abdominal sternites, spread over body using combs of hairs on hind legs. Antennae reduced to six or fewer segments; rostrum with four segments, segment two telescoping into segment one. Wing venation extremely reduced. First instar mobile; subsequent instars sedentary, with atrophied appendages; vasiform orifice present at tip of abdomen for expelling honeydew: anus opening into deep median fold in tergite eight, with lingula flicking away droplets forming therein; quiescent prepupal and pupal instars present prior to adulthood.
