<Tr> <Td_colspan="2"> <P> Tettigarctidae Cicadidae </P> </Td> </Tr> <P> The cicadas (/ sɪˈkɑːdə / or / sɪˈkeɪdə /) 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, Tettigarctidae, with two species in Australia, and Cicadidae, with more than 3,000 species described from around the world; many species remain undescribed . </P> <P> Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings . They have an exceptionally loud song, produced in most species by the rapid buckling and unbuckling of drumlike tymbals . The earliest known fossil Cicadomorpha appeared in the Upper Permian period; extant species occur all around the world in temperate to tropical climates . They typically live in trees, feeding on watery sap from xylem tissue and laying their eggs in a slit in the bark . Most cicadas are cryptic, singing at night to avoid predators . The periodic cicadas spend most of their lives as underground nymphs, emerging only after 13 or 17 years, which may reduce losses by starving their predators and eventually emerging in huge numbers that overwhelm and satiate any remaining predators . The annual cicadas are species that emerge every year . Though these cicada have life cycles that can vary from one to nine or more years as underground larvae, their emergence above ground as adults is not synchronized so some appear every year . </P> <P> Cicadas have been featured in literature since the time of Homer's Iliad, and as motifs in art from the Chinese Shang dynasty . They have been used in myths and folklore to represent carefree living and immortality . Cicadas are eaten in various countries, including China, where the nymphs are served deep - fried in Shandong cuisine . </P>
