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 ...
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.
Periodical cicadas are assigned to broods based on their year of emergence and life-cycle length. The other three 13-year species (M. tredecim, M. tredecassini, and M. tredecula) are represented in all three of the extant 13-year broods: Brood XIX (emerging in 2011), Brood XXII (emerging in 2014), and Brood XXIII (emerging in 2015).

Unlike periodical cicadas, whose appearances aboveground occur at 13- or 17-year intervals, Neotibicen species can be seen every year, hence their nickname "annual cicadas". Despite their annual appearances, Neotibicen probably take multiple years to develop underground, because all cicada species for which life cycle lengths have been measured ...
