The numbers will be staggering. The noisy little critters will outnumber humans more than 600 to 1 as they awaken from their 17 year naps over the next few weeks.
The heaviest numbers will be on the east coast from North Carolina to the Connecticut area.
Scientists are calling the coming invasion Brood II.
The good news is the cicadas won’t hurt people or other animals but they sure are loud
"It's not like these hordes of cicadas suck blood or zombify people," an Illinois university entomologist quipped.
So what are the creatures going to do?
The insects come back to reproduce and will come out when the ground temperature hits exactly 64 degrees. Then they’ll do their business and they’ll spend a little time living in trees.
Then the older bugs will die and their proliferation of little insect children will return to the earth and not show their faces again until the year 2030.
Science is fun huh?
