A lawn care customer called about small insects buzzing around his head last evening at dusk near his tree. He said they were the size of his baby finger. Told him to check google images for European chafer. The European chafer is a foreign import that looks like our Canadian June bug. It is a little smaller, but for all intents it looks the same. Unless you had both the European chafer and a June beetle side by side- you probably couldn't tell the difference.
Sure enough, that's the adults on their mating flights getting ready to lay eggs that hatch into white grubs.

Prepare to apply nematodes to help reduce damage from grubs.
