Magicicada cassinii

''Magicicada cassinii'',While the original and correct spelling for Fisher's 17-year species is ''cassinii'', with two 'i's, a large majority of publications have spelled the name ''cassini'' since the mid-1960s. However, the original spelling has been maintained throughout by taxonomic catalogues, and the rules of nomenclature support the priority of ''cassinii'' . The correct spelling for the 13-year relative is ''tredecassini''. sometimes called the 17-year cicada or the dwarf periodical cicada, is a species of periodical cicada. It is endemic to the United States. It has a 17-year lifecycle but is otherwise indistinguishable from the 13-year periodical cicada ''Magicicada tredecassini''. 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.
