Magicicada cassinii
Cassin's periodical cicada, dwarf periodical cicada
Magicicada cassinii is one of three species of 17-year periodical cicadas endemic to eastern North America. Adults emerge synchronously every 17 years in massive broods, with males producing distinctive calling songs peaking at 4-7 kHz. The species is morphologically indistinguishable from the 13-year Magicicada tredecassini, and the two are collectively referred to as 'cassini-type' periodical cicadas. Males are notable for their ability to synchronize courting behavior, creating choruses of tens of thousands of individuals.
