历史上，大多数北美期刊蝉（半翅目：蝉科：魔术蝉属）。戴维斯1925年）分布记录已映射在县级分辨率。近几十年来，Magicicada育雏分布，特别是边缘已被映射在一个更高的分辨率，2000年后使用GIS技术的帮助。17年蝉的第六窝出现在2000年和2017年，是第一个连续几代完成详细绘图的蝉。叠加两代的记录表明，在某些地方，Brood VI在2000年至2017年期间略微扩大了其范围，尽管考虑到所使用的方法，测量到的变化接近可检测性的下限。即便如此，没有一个简单的替代方案可以轻易地解释这些观测结果。我们也支持亚历山大和摩尔的主张，M。cassini不会出现在第六窝。
Historically, most North American periodical cicada (Hemiptera: Cicadidae: Magicicada spp. Davis 1925) distribution records have been mapped at county-level resolution. In recent decades, Magicicada brood distributions and especially edges have been mapped at a higher resolution, aided by the use of GIS technology after 2000. Brood VI of the 17-yr cicadas emerged in 2000 and 2017 and is the first for which detailed mapping has been completed in consecutive generations. Overlaying the records from the two generations suggests that in some places, Brood VI expanded its range slightly between 2000 and 2017, although the measured changes are close to the lower limit of detectability given the methods used. Even so, no simple alternative to range expansion easily accounts for these observations. We also bolster Alexander and Moore's assertion that M. cassini does not occur in Brood VI.
