It's that time of year again: cicadas are expected to emerge in the East Coast after living underground for 17 years.
This year's periodical cicadas, which will appear this month in North Carolina, Virginia and West Virginia, are called Brood IX (9).
Cicadas emerge when the ground reaches 64 degrees, according to the website Cicada Mania.
John Cooley, an entomologist at the University of Connecticut, told USA TODAY that cicadas pop up in the evening "to be able to do the things that they have to do, but it's also going to be dark enough that they're not going to get wiped out by birds."
