One thing is certain-cicadas are some of the most unique creatures on planet Earth! Have you ever heard the buzz of a cicada brood? Maybe you’ve seen the exoskeletons left behind by their molt. By emerging at strategic times, cicadas may avoid some dangers and have a more successful mating season. The insects are food for many animals, including birds, lizards, and sometimes humans. However, they believe the cycle has evolved to help cicadas avoid predators. Scientists aren’t certain what causes a brood to emerge every 13 or 17 years. Adult cicadas leave behind an empty shell of their previous form. You may have seen the results of this process before. They also molt, meaning they shed their nymph exoskeleton. While above ground, they feed on sap from twigs and other vegetation. They spend between four and 17 years in this phase of life.įinally, the nymph cicada emerges to become an adult. There, they feed on liquid from plant roots. Once these eggs hatch, nymph cicadas emerge and burrow into the ground. First, female cicadas lay eggs-up to 400 of them. Why do some broods only emerge every 17 years? It has to do with the cicada life cycle. However, their life cycles overlap so that a brood of the insects come above ground each year. ![]() They still only emerge once in their lives-in order to mate. These are called annual cicadas, and they live much shorter lives than periodical species-between two and five years. The other three broods emerge every 13 years.Įlsewhere on the planet, cicadas emerge each year. However, 12 of these broods only emerge every 17 years. Like all cicadas, they live most of their lives underground. Of the over 3,000 species of this insect, those on this continent are the only ones considered periodical. Why is that?
