Nasty lime green beetle turning a bit yellow now. They do fly and they don’t like it when I water.

Moved in, on the leaves of the pumpkin plants, now starting on the blossoms. Then some went to the sunflowers, too.
These are the BIG pumpkins, and don’t want them going to the pumpkins themselves.
Extreme north central Iowa, close to the Minnesota border.
We believe these are Northern Corn Rootworms, Diabrotica barberi, a species of Skeletonizing Leaf Beetle, based on images posted to BugGuide.
