Group Bordenstein Lab

We noticed these beetles that would come out every night around 8pm and bother us. They were loud and would run into us. Not very intelligent, they would routinely get stuck on their backs and would not be able to do anything until they fell off the surface they were on. There were so many of them! We thought they had something to do with the grape plant next to our fence, grape beetles look very similar but have spots. These have no spots. We identified them as lawn grubs, and these are May/June beetles.
