The term periodical cicada is commonly used to refer to any of the seven species of the genus Magicicada of eastern North America, the 13- and 17-year cicadas.They are called periodical because nearly all individuals in a local population are developmentally synchronized and emerge in the same year.
Cicada nymphs drink sap from the xylem of various species of trees, including oak, cypress, willow, ash, and maple. While common folklore indicates that adults do not eat, they actually do drink plant sap using their sucking mouthparts. [58] [59] Cicadas excrete fluid in streams of droplets due to their high volume consumption of xylem sap. [60]
Brood XIX includes all four different species of 13-year cicadas: Magicicada tredecim (Walsh and Riley, 1868), Magicicada tredecassini (Alexander and Moore, 1962), Magicicada tredecula (Alexander and Moore, 1962), and the recently discovered Magicicada neotredecim (Marshall and Cooley, 2000). 2011 was the first appearance of Brood XIX since the discovery of the new species, which was first ...
In the U.S., there are at least 15 separate cycles, or "broods," of periodic cicadas. They’re called periodic based on the number of years they spend underground. Emergence times vary from 13 to ...

Map of periodic cicada broods with Brood X shown in yellow. Every 17 years, Brood X cicada nymphs tunnel upwards en masse to emerge from the surface of the ground. The insects then shed their exoskeletons on trees and other surfaces, thus becoming adults. The mature cicadas fly, mate, lay eggs in twigs, and then
Brood XIII of the 17-year cicada, which reputably has the largest emergence of cicadas by size known anywhere, and Brood XIX of the 13-year cicada, arguably the largest (by geographic extent) of all periodical cicada broods, were expected to emerge together in 2024 for the first time since 1803.
