Cicadas

thumb|Neotibicen linnei Cicadidae, the true cicadas, is one of two families of cicadas, with about 3,400 species in over 520 genera worldwide; it contains most living cicada species, except for the two belonging to its sister taxon, the Tettigarctidae. The classification of this family, of often very similar insects, has undergone many revisions, continuing into the 21st century; for example, many species previously assigned to the type genus Cicada, are now placed in different tribes.

The cicadas () are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, the Tettigarctidae, with two species in Australia, and the Cicadidae, with more than 3,000 species described from around the world; many species remain undescribed. Nearly all cicada species are annual cicadas with the exception of the few North American periodical cicada species, genus Magicicada, which in a given region emerge en masse every
