If Paul Revere were still alive, he’d probably be shouting, “ The cicadas are coming !” Probably.

And they are , indeed, coming: One of the largest cicada broods around will emerge in Pennsylvania this spring.

According to CicadaMania.com , Brood XIV (14) will grace 13 states with their presence this upcoming spring season, Pennsylvania among them. They’ll also pop up in Georgia, Kentucky, Massachusetts, Maryland, North Carolina, New Jersey, New York, Ohio, Tennessee, Virginia and West Virginia.

This brood involves all three 17-year species, the site explains: Magicicada septendecim, Magicicada cassini, and Magicicada septendecula.

The University of Connecticut states that Brood XIV is, in fact, the second largest periodical brood there is. Brood XIX is the largest.

“Periodical cicadas are found in eastern North America and belong to the genus ‘Magicicada,’” explains the University of Michigan . “There are seven species — four with 13-year life cycles (including one new species described in 2000), and three with 17-year cycles.

“The three 17-year species are generally northern in distribution, while the 13-year species are generally southern and midwestern. Magicicada are so well-synchronized developmentally that they are nearly absent as adults in the 12 or 16 years between emergences.”

They tend to be called locusts, but they’re not, the University of Michigan adds. Additionally, while they’re certainly freaky-looking, they’re harmless to humans ( and even nutritious ).

Brood XIV is expected to emerge around mid-May. This emergence will end late June.
