Cicadas

Cicadas, a number of insects belonging to the order Rhynchota andformingthe family Cicadidae. They have suctorial mouths and four wings, and undergo an incomplete metamorphosis. The most interesting point about them is the presence in the males of the "abdominal drums" by which they make a harsh chirping noise. The female is songless; it has a piercing ovipositor, by which it bores into trees and there lays its eggs. Most of the Cicadas are tropical, but one species, Cicada anglica, Curt, occurs in England. They are usually known as locusts in America and Australia, but have no connection with those insects. The Cicadas include some of the largest of the Rhynchota.
