European Chafer Beetle infestation?

I’ve noticed the last few evenings sitting on the patio near dusk, a swarm of insects that fly around like a loaded up bumble bee, kinda stupid like.

Did some digging around and I think they are what’s called an invasive European chafer beetle, but I’m no bug expert. They don’t seem aggressive or anything but I read that live in turf and can destroy your lawn.

Just curious if anyone else has noticed these floating around. I’ve never noticed them before.

Cheers!
