- What: Brood VII is the smallest periodical cicada brood in the U.S., and is isolated in the Finger Lakes area of New York State. Only one species of cicada belongs to the brood: Magicicada septendecim (click link for sounds, video). This cicada has a 17-year life cycle. Sadly, Brood VII will likely be the next Brood to go extinct.
- When: May or June. Magicicada cicadas typically emerge in the spring, once the soil underground where they live reaches approximately 64 degrees Faraihneght.
- Where: the Finger Lakes area of NY State. The following counties have had these cicadas in the past: Cayuga, Livingston, Monroe, Onondaga, Ontario, Seneca, Steuben, Wyoming, York.
There’s a strong possibility that Brood XXII stragglers will also emerge in parts of Louisiana, Mississippi, southern Ohio & northern Kentucky. So, if you come across periodical cicadas in those areas, they’re Brood XXII, not VII.
