What is a Cicada?
Cicada: (si-car-da) any large broad insect of the homopterous family Cicadidae, most common in warm regions. Cicadas have membranous wings and the males produce a high-pitched drone by vibration of a pair of drumlike abdominal organs.
Cicadas are the world's loudest insects, with some of the 2,500 species reaching 120 decibels - the equivalent to what you hear when sitting in the front row of a loud rock concert.
