Why do cicadas only 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.Click to see full answer. Regarding this, why are…
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.

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.Subsequently, question is, do cicadas only come out every 17 years? Cicada Cycles. Cicadas spend years underground and come out once in a blue moon for a frenzy of activity. But certain broods, like the one that emerged in 2004, come out like clockwork every 13 or 17 years. In this Science Update, you’ll hear what’s so special about these numbers. Regarding this, 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.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.
