Update (June 17th): I just got back from Onondaga county and I can report that the emergence is in full swing. Lots of chorusing and mating. The best locations are around the Onondaga Nation reservation. If you visit, please do not trespass into the reservation — there are plenty of cicadas outside of it. John Cooley of Magicicada.org said there are also reports of cicadas in the Green Lakes State Park.
Here’s a short video that shows some of the action:
— Cicada Mania (@cicadamania) June 16, 2018
Periodical cicadas (Magicicada septendecim, people call them “locusts”) will emerge in the Finger Lakes area of New York state in 2018.
This group of cicadas is called Brood VII (7) and is known as the Onondaga Brood. This brood is shrinking, and will likely be the next periodical cicada brood to go extinct
- 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: June, but perhaps May if it’s a very warm year. 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.
- Where they appeared (last) in 2001: Onondaga and Livingston.
- 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.
