Aside from Brood X, what else is happening in terms of Periodical cicadas?
- Expect some early-emerging cicadas from Brood XIV, showing up 4 years early. Brood XIV exists in Georgia, Kentucky, Indiana, Massachusettes, Maryland, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia.
- There might be some 1-year stragglers form Brood IX. Brood IX is in North Carolina, Virginia and West Virginia.
- There might be some 4-year stragglers from Brood VI. Brood VI is found in Georgia, North Carolina, South Carolina, and Oklaholma. And Ohio?Brood VI is a weird one.
When I was a graduate student studying hearing at Princeton, in 1970-71, we studied the sounds and hearing of Brood X cicadas during a big emergence in that area. We found that the chorus could be up to about 130 dB SPL, a level that appeared likely to repel predators such as birds. https://doi.org/10.1126/science.171.3967.212
I was doing research on bats, but the cicadas were so prominent that we stopped to study them, knowing that the opportunity would be short.
