The periodical cicada spends the vast majority of its life underground, emerging after 13 or 17 years (depending on the species) to transform, reproduce and ultimately die over the space of just a few days. Huge populations of these insects have synced up to emerge within the same window of time to give them the best chance of successfully finding a mate and producing young before they are eaten by predators or expire naturally. These populations are called broods, and one of the largest—Brood X— emerged in 2021.
