Why do cicadas come out every 17 years?

The seven periodical cicada species are so named because, in any one location, all of the members of the population are developmentally synchronized—they emerge as adults all at once in the same year. This periodicity is especially remarkable because their lifecycles are so long—13 or 17 years.

Hereof, what do cicadas do for 17 years?

The cicada will stay underground from 2 to 17 years depending on the species. Cicadas are active underground, tunneling and feeding, and not sleeping or hibernating as commonly thought. After the long 2 to 17 years, cicadas emerge from the ground as nymphs.

Subsequently, question is, what year are the cicadas coming back? The 13-year cicadas won't arrive until 2024. The last time they emerged was 2011. The 17-year cicadas that last emerged in 2004 will return in 2021, Tuggle said.

why are cicadas every 17 years?

One Of These Broods Is Not Like The Other But if periodical cicadas only emerge every 13 or 17 years, why do we see them every year? It's because they don't all emerge at once. Each of these broods emerge in different years, so residents in cicada regions rarely spend a summer without them.

Is 2020 a cicada year?

The next brood of periodic cicadas is set to emerge in North Carolina, Virginia, and West Virginia in 2020 and in the entire eastern United States in 2021. So don't fret if you see hundreds of bugs flying around; it's perfectly natural. They are harmless and beneficial to the environment.
