TRILLIONS of cicadas are set to invade the United States for the first time in 221 years, scientists say.
In late April, two large broods of periodical cicadas are expected to emerge from the ground for a noisy mating frenzy.
“Billions, even trillions, of cicadas are going to emerge at the same time across 17 states,” Chris Simon, a professor in UConn’s Department of Ecology and Evolutionary Biology, told Live Science.
Brood XIII and XIX have been living underground for 17 and 13 years respectively.
They will soon emerge at the same time for the first time in 221 years.
Periodical broods are found in eastern North America and tend to emerge in large numbers.
Brood XIII will be seen around north-central Illinois, Ohio, and Iowa in the Midwest.
