Sternorrhyncha (Aphids, Scale, Whiteflies)

The Sternorrhyncha are a large group of plant-feeding insects with piercing/sucking mouthparts.  The morphology of these insects has become reduced to varying degrees in the course of adapting to an extremely specialized lifestyle- some of the scale insects are scarcely even recognizable as living creatures.  The life cycle of some species can be remarkably complicated, with alternating winged and non-winged forms, changes of host plant, and cycles of sexual and asexual reproduction.  A few Sternorrhyncha are important crop pests, and many are tended by ants.
