Brood I (17-year)
The Blue Ridge Brood
Brood I is generally found in upland areas of the Blue Ridge.
Brown symbols on the map above were generated from verified records in the Cicada Central Database on 20 January 2013.
Blue symbols on the map are based on Marlatt (1923).
Gold symbols are based on Simon (1988); smaller symbols are records with a lower degree of certainty.
These records have not been field checked.
A project is currently underway to make new maps of periodical cicada broods. See the Magicicada mapping project homepage and the Geospatial Data Clearinghouse.
