The diagram delineates the life cycle of the cicada, an intriguing insect known for its prolonged development stages.
Overall, the cicada’s life cycle is characterized by three distinct phases: the egg, the nymph, and the adult cicada, with each phase exhibiting significant durations both above and below ground.
Initially, cicada eggs are deposited within tree branches. This incubation period lasts from approximately 2 to 7 months. Once hatched, the emerging nymphs burrow underground, where they reside for extensive periods, typically ranging from 2 to 17 years. This underground phase is crucial for their growth and involves the construction of tunnels in proximity to tree roots, serving as both shelter and a source of nourishment.
Upon completion of their extensive subterranean life, nymphs ascend to the surface, where they undergo a rapid metamorphosis, taking approximately 20 to 150 minutes to shed their exoskeleton. This significant transformation heralds their emergence as adult cicadas. Following this transition, the adult cicadas engage in mating behaviors and subsequently lay eggs, thereby perpetuating the cycle. The varied duration of each stage underscores the cicada’s unique adaptive strategies within its ecological niche.
