Most of the species belong to the family Cicadidae.

 Male cicadas produce loud noises by vibrating membranes (timbals) near the base of the abdomen. Most North American cicadas produce rhythmical ticks, buzzes, or whines, although in some species the "song" is musical.

 Eggs are usually laid in woody tissues; newly hatched nymphs burrow into the ground where they suck juices from roots of perennial plants. Nymphs usually undergo five molts during the several years required to reach maturity. Although not ordinarily considered a pest, the females, if numerous, may damage young saplings during their egg laying.

 About 1,500 species of cicadas are known; most are tropical and occur in deserts, grasslands, and forests. In addition to the dog-day cicada (Tibicen and others) that appears yearly in midsummer, there are also periodic cicadas.

 Cicadas have been used in folk medicines in different cultures, as religious and monetary symbols, and as an important source of food. Their song once was considered to forecast weather changes. In China, male cicadas were caged for their song. The cicada appears in the mythology, literature, and music of many cultures.

 Cicada slough, used by the Chinese as an herbal drug, is the shell of Cryptotympana pubricius of the family Cicadidae. This drug is mainly produced in Shandong, Hebei, Jiangsu, Zhejiang, etc., picked and reaped in summer, dried in the sun with earth removed and used when raw.
