Cotinis nitida

Extensioneers are receiving reports of Green June Beetles (Cotinis nitida, family Scarabaeidae) cruising lawns in Ohio. Despite the "June" in their common name, these native scarab beetles always make their annual appearance in July in Ohio. They typically gather en masse to terrorize gardeners, golfers, sunbathers, small children, and pets as they buzz over home lawns and golf courses.

Beth Scheckelhoff (OSU Extension Putnam County) reported she observed large numbers of Green June Beetles (Cotinis nitida, family Scarabaeidae) buzz-bombing the OSU Ag campus yesterday. The behavior of the adults and larvae (grubs) of this North American native makes this beetle a legitimate summer oddity.

I came across a green June beetle larva (grub) last Thursday slowly slinking across a driveway. This is one of largest and strangest white grubs you'll ever see in Ohio. First, the mature grubs are huge measuring well over 1" in length. They look like white grubs on steroids.
