From left to right you will see the fully mature larval cicada as it leaves the ground to molt into the adult insect (picture 1). Cicadas emerge from the immature stage (pictures 2-4) gradually but in just a few minutes. The adult insect is fully developed inside; however, its skin is soft (white to translucent in appearance). Through hydrostatic pressure the adult insect breaks through and gradually crawls out of its larval exoskeleton. As it pumps itself up it becomes larger, and the wings spread to its full adult form (pictures 5-7). Very quickly proteins within the body cause the insect to harden and darken, at which point the cicada takes its final form (picture 8). It leaves behind its larval exoskeleton, commonly referred to as a cicada shell (picture 9).
