CicadaPosted by Alfredo J. Martiz J. (Panama City, Panama) on 12 August 2007 in Animal & Insect. A cicada is an insect of the order Hemiptera, suborder Auchenorrhyncha, in the superfamily Cicadoidea, with large eyes wide apart on the head and usually transparent, well-veined wings. There are approximately 2,500 species of cicada around the globe, and many remain unclassified. 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. Adult cicadas, sometimes called imagines, are usually between 2 and 5 cm (1 to 2 inches) long, although there are some tropical species that reach 15 cm (6 in), e.g. Pomponia imperatoria from Malaysia. Cicadas have prominent eyes set wide apart on the sides of the head, short antennae protruding between or in front of the eyes, and membranous front wings. Desert cicadas are also one of the few insects known to cool themselves by sweating, while many other cicadas can raise their body temperatures voluntarily to around 40 °C (104°F), even when the air temperature is only 18°C (65°F). Only males produce the cicadas' distinctive sound. Both sexes, however, have tympana, which are membranous structures used to detect sounds; thus, the cicadas' equivalent of ears. Adult cicadas have a sideways-ridged plate where the mouth is in normal insects. Tokyo University of Science, Noda Campus. August 10th, 2007. Funny note: I prepared the tripod, framed the photo, set up the shutter speed and aperture, made the photo, made another photo by accident (erased it at home), saw the preview of the photo in the camera to see the result, looked back to the tree again, there was no Cicada!
