n. pl. E. Cicadas (-dåz), L. Cicadæ (-dē).

1. Any species of the genus Cicada or of the family Cicadidae. They are large hemipterous insects, with nearly transparent wings.

A noted American species (Cicada septendecim) is called the seventeen year locust. Another common species is the dogday cicada.
