Broods are organized by 17-year and 13-year cicadas. Periodical cicada brood data is symoblized by brood number (I-XXIII) using a solid qualitative fill color for counties where the brood is found. Each brood layer includes the next emergence year for that brood. Broods with the soonest next emergence year are turned on by default while all other broods are turned off by default. Counties with multiple cicada broods are symbolized with a black hash fill symbol. |

A map service on the www depicting periodical cicada distribution and expected year of emergence by cicada brood and county. The periodical cicada emerges in massive groups once every 13 or 17 years and is completely unique to North America. There are 15 of these mass groups, called broods, of periodical cicadas in the United States. This county-based data, complied by the USFS Northern Research Station, depict where and when the different broods of periodical cicadas are likely to emerge in the US through 2031. The data was compiled for the 2011 publication entitled "Avian predators are less abundant during periodical cicada emergences, but why?" (Koenig et al. http://dx.doi.org/10.1890/10-1583.1) using data from periodical cicada publications listed below. 1) Marlatt, C. L. 1907. "The periodical cicada". Bulletin of the USDA Bureau of Entomology 71:1–181. 2) Simon, C. 1988. "Evolution of 13- and 17-year periodical cicadas". (Homoptera: Cicadidae). Bulletin of the Entomological Society of America 34:163–176. 3) Liebhold, A. M., Bohne, M. J., and R. L. Lilja. 2013. "Active Periodical Cicada Broods of the United States".
