2019 Magicicada Records

This map shows the progress of our mapping teams as we map Brood VIII. Not to be redistributed or published without prior written permission.

The map above shows confirmed presence (cicada symbols) periodical cicada records collected by project collaborators during the current periodical cicada emergence. Small symbols indicate scattered individuals; large symbols indicate choruses.  Negative (absence) records are indicated by a black “X”.    Historical records from prior Brood VIII emergences are marked with an “H”. Nearby records of Brood V are marked with a black (positive) or red (negative) “V” (This map includes only the most relevant Brood V records).
