People in the South and Midwest will have a particularly noisy summer, as two dueling cicada broods emerge simultaneously for the first time since 1803.

Cicadas are known for signature chirping noises - males will vibrate abdominal flaps, while their female counterparts respond by loudly flicking their wings. With the cicada mating season lasting until the end of July, people in the impacted regions can expect noisy evenings for the majority of the summer, Yale Environment 360 reported.

While cicadas regularly emerge in 13-and-17-year cycles, it is rare that the two cycles happen concurrently - in fact, it's a once-in-every-other-lifetime phenomenon.

"This is the first time these two broods are going to be emerging in the same year since Thomas Jefferson was in the White House," entomologist Floyd Shockley told Reuters.

Though only Illinois will see the broods overlap, large swaths of the country will see - and hear - the emergence of new cicadas, as the warmer months begin.

The broods in question, XIII and XIX, will emerge in the central and southern regions of the country. The Brood XIII cicadas were born in 2007 and spent 17 years growing underground, while the Brood XIX cicadas were born in 2011.

"They don't often coincide in time, but to have them coincide in time and space is even more unusual," insect ecologist John Lill told Scientific American. "That's what's happening this year that's generating a lot of buzz-pun intended."
