Although some Homoptera are secondarily wingless, the majority have membranous or uniformly textured wings that fold tent-like over the body at rest. As nymphs, they live underground and feed on the roots of trees and shrubs. In contrast, the aphids are tiny, soft-bodied insects with multiple generations per year.
All species are terrestrial herbivores.
They often resemble thorns or small twigs. Aphids are considered the most important carriers of viral plant diseases. The insect lives on various fig trees in the tropics. It is a scale insect that lives on prickly pear cacti. The galls are usually open at one end so the insects can come and go freely.
