Ravinia plans for cicada cantata: they’re moving a music festival to avoid the noise.
Someone asked when the cicadas will emerge in the Chicago area. My guess is late May, depending on the air temperature. The article referenced above predicts late May or early June. If you have any insight to share, please do!
I’d say that late May will be the start and it runs through June. I only recognize this since I lilved in Chicago my entire life and do remember when they last came out when I was 13 years old. I was still in grammar school and we had a field trip to Brookfield Zoo, which would’ve been late May at best.

I’m visiting my family in Northern Illinois in Early June – so I’m hoping the Cicadas are numerous and loud. We got them in Maryland a couple of years ago and I had a delightful time photographing and videotaping them. Thanks to this website I was even mentioned in the Washington Post!
Like the new look of your site, BTW.

Gene Kritsky was nice enough to send a paper he wrote with a formula for predicting the emergence date. E = (19.465 2 t)/0.5136, where E = emergence start date in May and t = average April temperatures in °Celsius. His formula worked like a charm for predicting the Brood X emergence in Cincinnati. 80% of his sites had begun the emergence on the predicted date of May 14th of that year. Also when the ground temperature reaches a consistent 64° Farenheit that is another good sign the mergence is about to begin.
