That looks like a Japanese beetle. In your first photo, notice the row of white tufts along the beetle's side, just below its copper colored wing covers.

In your second picture, the unique antenna tip is visible. That is also an identifying mark for Japanese beetles.
Here are two images that emphasize the characteristics.
