Yeah I first noticed it like 10-15 years back when I visited my aunt in another town. Her place was always full of June bugs who would smash into your face repeatedly like a bunch of assholes, when we were kids. We even named her place after the bugs. But when I went back as an adult 15 years or so ago, there wasn't a single one. My aunt said they vanished over a couple of years. I always wondered if they just didn't like her property anymore or something, but it was likely climate change in the area.
