Cicadas spend years underground and come out once in a blue moon for a frenzy of activity. But certain broods, like the one that emerged in 2004, come out like clockwork every 13 or 17 years. In this Science Update, you'll hear what's so special about these numbers.
Every 13 or 17 years, some parts of the country are on cicada watch. They're waiting for billions of the thumb-sized insects to crawl out of the ground, create an incredible racket with their calls, and then die after successfully mating. One Science Update listener asked how the bugs know when to finally come out.
