For the last 17 years, millions of these cicadas have been sleeping in the ground, but in May they will come out of hibernation and start buzzing.

For the last 17 years, millions of these cicadas have been sleeping in the ground, but in May they will come out of hibernation and start buzzing.
They will make their appearance as soon as soil 8 inches down reaches an average of 64 degrees.
They will stick around for about six weeks, reproducing and being very loud, before the droning buzz fades away for another 17 years
