Yeah, from what I read, they're an invasive species from Asia and they started in Pennsylvania. Sounds like they tried to quarantine them but from the looks of things, it definitely didn't work. This was a few years ago, so unfortunately, I don’t think winter will wipe them all out.

And yeah, we still get the 17 year cicadas. Last we had them was in 2013. They were loud and sounded like a UFO. Honestly, good riddance, they were everywhere and were pretty big, about the size of a finger. Stepping on one was just... bleh.
