Brood XIX (also known as Brood 19 and the Great Southern Brood) is one of 15 separate broods of periodical cicadas that appear regularly throughout the southeastern United States. Every 13 years, Brood XIX tunnels en masse to the surface of the ground, lays eggs, and then dies off in several weeks.

Although entomologist C. L. Marlatt published an account in 1907 in which he argued for the existence of 30 broods, over the years a number have been consolidated and only 15 are recognized today as being distinct. [1]

Its most recent appearance was in the spring and early summer of 1998 throughout an area roughly enclosed by Georgia, Texas, Missouri and Maryland. The next three appearances will be in 2011, 2024 and 2037. [2] [3]
