Any of several insects of the family Cicadidae. Most species are tropical, but a few occur in Europe and North America. The adults live on trees, whose juices they suck. The males produce a loud, almost continuous, chirping by vibrating membranes in resonating cavities in the abdomen.
Cicadas with a periodic life cycle, such as the 13-year cicada and the 17-year cicada, are found only in the USA. These species spend most of their lives as larvae underground, synchronizing their emergence every 13 or 17 years depending on species.
