The Brood-X cicada is the longest-lived insect in North America.

And now, in fifteen states - including Tennessee - it is rising from the ground, seventeen years after the last time.

You can learn about these periodical cicadas - and more - in the latest “Get Out Chattanooga,” the magazine from The Chattanooga Times Free Press.

Sunny Montgomery is assistant editor and digital editor for “Get Out.”
