The diagram illustrates the life cycle of a cicada, detailing its development through three main stages: egg, nymph, and adult cicada. The process takes between 2 to 17 years to complete, depending on environmental factors and species variation.
The cycle begins when adult cicadas lay eggs inside tree branches. These eggs take approximately 2 to 7 months to hatch, at which point the young cicadas, known as nymphs, emerge. The nymphs then burrow underground, where they live and grow by tunneling near tree roots. This stage is the longest in the life cycle, lasting between 2 to 17 years. During this period, nymphs undergo multiple molting phases as they gradually mature.
Once fully grown, the nymphs resurface from the ground and attach themselves to a tree. At this point, they shed their exoskeletons in a process that lasts between 20 to 150 minutes, transitioning into adult cicadas. The cycle then repeats when the adult cicadas lay eggs on tree branches.
In comparison to other insects, the cicada’s life cycle is unique due to its prolonged nymph stage underground. Unlike butterflies, which undergo metamorphosis relatively quickly, cicadas take several years before reaching adulthood. This extended development ensures their survival, as they emerge in large numbers to overwhelm predators.
Overall, the cicada’s life cycle is characterized by a lengthy underground phase followed by a brief adult stage, which primarily focuses on reproduction before the cycle begins again
