Cicada emergence refers to the process when adult cicadas, particularly those from the Magicicada genus, come out of the ground after spending years as nymphs. This event typically occurs in late spring or early summer, depending on the species and local climate conditions. The nymphs burrow underground, feeding on plant roots, and when the time is right, they climb up trees or other surfaces to molt into their adult form. During emergence, cicadas shed their exoskeletons, leaving behind empty shells. This synchronized event can involve millions of cicadas emerging at once, creating a loud chorus of mating calls. The adult cicadas live for a few weeks to a few months, during which they mate and lay eggs, continuing the life cycle.
