Cicada 2024 Brood. Two broods of cicadas—brood xix and xiii, which emerge every 13 and 17 years, respectively—are appearing together in 2024. A cicada brood is a group of periodical cicadas that emerge in a given year, and there can be multiple species.
A double brood of cicadas will emerge in the midwest and southeast in late april through the middle of may. This spring, two broods of cicadas will emerge in the midwest and the southeast, in their first dual appearance since 1803.
