A cicada is any of several insects of the order Hemiptera, suborder Auchenorrhyncha, in the superfamily Cicadoidea, with small eyes wide apart on the head and usually transparent, well-veined wings. There are circa 2500 species of cicada around the globe, many remain undescribed. Cicadas live in temperate to tropical climates where they are one of the most widely recognized of all insects, mainly due to their large size and remarkable (and often inescapable) acoustic talents.
