 | | Each synchronized periodical cicada emergence was thought to contain up to three species: 13-year Magicicada tredecim, Magicicada tredecassini and Magicicada tredecula; or 17-year Magicicada septendecim, Magicicada cassini, and Magicicada septendecula. |
 | | Magicicada neotredecim is divided into two major geographic groups that emerge in different years; thus, although Magicicada neotredecim last emerged in 1998, another population will emerge in 2002. |
 | | Study of Magicicada neotredecim and its interactions with other similar species provides valuable information about this unique species complex, the mechanisms by which life cycles change, and the ways in which populations of the same life cycle become asynchronous. |
