See main article: Cassini periodical cicadas.
Magicicada tredecassini is a species of periodical cicada endemic to the United States. It has a 13-year lifecycle but is otherwise indistinguishable from the 17-year periodical cicada Magicicada cassini. The two species are usually discussed together as "cassini periodical cicadas" or "cassini-type periodical cicadas." Unlike other periodical cicadas, cassini-type males may synchronize their courting behavior so that tens of thousands of males sing and fly in unison.[1] [2]
Their median life cycle from egg to natural adult death is around thirteen years. However, their life cycle can range from nine years to seventeen years.[3]
