周期蝉(同翅目：蝉科：蝉属)仅在美国东部落叶林区发现，其生命周期为13年(密西西比河谷州和南部各州)或17年(13年范围的北部和西部)。没有中间生命周期的种群。几乎每年，在大平原以东的某个地方，都能发现一群同步出现的周期性蝉。这些群体被称为“雏鸟”，完全由它们出现的年份来定义。无论是大的(覆盖几个州)还是小的(覆盖一个州的几个县)，雏鸟往往占据一个大致相连的地理区域，在那里当地人口零星分布。马拉特(1898,1907)绘制了详细的地图，并按时间顺序编号(17年的雏鸟从I到XVII；13年的雏鸟从XVIII到XXX)。在可能出现不同的17年蝉窝的17年中，有13年有很好的记录。在可能出现不同的13年孵化的13年中，现在只有3年确认了孵化。有证据表明
Periodical cicadas (Homoptera: Cicadidae: Magicicada spp.) are found only in the eastern deciduous forest region of the United States and have life cycles of either 13 years (Mississippi Valley and southern states) or 17 years (north and west of the 13-year range). There are no populations with intermediate life cycles. Almost every year, somewhere east of the Great Plains, a synchronized group of periodical cicadas can be found emerging. These groups, called "broods," are defined solely by their year of emergence. Whether large (covering several states) or small (covering a few counties in one state), broods tend to occupy a roughly contiguous geographic area in which local populations are patchily distributed. Broods were numbered in chronological order (I through XVII for 17-year broods; XVIII through XXX for 13-year broods) and mapped in detail by Marlatt (1898, 1907). Of the 17 possible years in which different 17-year cicada broods could emerge, 13 have well documented broods. Of the 13 years in which different 13-year broods could emerge, only three now have confirmed broods. There is evidence of
