CRYPTOTYMPANA MANDARINA Cryptotympana mandarina is a cicada found in China, Laos, Vietnam, India, Thailand, and likely adjacent nations. Cicada, family Cicadidae, any of a group of sound-producing insects (order Homoptera) that have two pairs of membranous wings, prominent compound eyes, and three simple eyes (ocelli). Cicadas are medium to large in size, ranging from 2 to 5 cm (0.8 to 2 inches). The oldest known definitive fossils are from the Paleocene, a nymph from the Cretaceous Burmese amber has been attributed to the family, but could also belong to the Tettigarctidae. Cicadas are large insects characterized by their membranous wings, triangular-formation of three ocelli on the top of their heads, and their short, bristle-like antennae. Cicadas are generally separated into two categories based on their adult emergence pattern. Annual cicadas remain underground as nymphs for two or more years and the population is not locally synchronized in its development, so that some adults mature each year or in most years. Periodical cicadas also have multiple-year life cycles but emerge in synchrony or near synchrony in any one location and are absent as adults in the intervening years. The most well-known periodical cicadas, genus Magicicada, emerge as adults every 13 or 17 years. Cicadas are known for the loud airborne sounds that males of most species make to attract mates. One member of this family, Brevisana brevis, the "shrill thorntree cicada", is the loudest insect in the world, able to produce a song that exceeds 100 decibels. Male cicadas can produce four types of acoustic signals: songs, calls, low-amplitude songs, and disturbance sounds. Unlike members of the order Orthoptera (grasshoppers, crickets, and katydids), who use stridulation to produce sounds, members of Cicadidae produce sounds using a pair of tymbals, which are modified membranes located on the abdomen. In order to produce sound, each tymbal is pulled inwards by a connected muscle, and the deformation of the stiff membrane produces a Click.
