HELP! What is this bug!?
What is this little green pest? They come here in the mid-west every year around August. There are hundreds of them and they are eating all of my flowers and destroying my garden- especially my petunias and begonias! Help, what are they? Some sort of Aphid? How do I get rid of them? Thanks!

This is one of the Skeletonizing Leaf Beetles. Our suspicion is that it is the Northern Corn Rootworm, Diabrotica barberi, or a very closely related species. The larvae feed on the roots of corn, and the adults skeletonize leaves and blossoms.

    Wow, I’ve seen this bug, Northern Corn Rootworm, every year I can rememer, but this year is the worst I have ever seen. The siding on my house was covered, completely. The air was thick with them, had to be in numbers approaching the national debt. Okay, maybe not that many. Any reasons for the large numbers this year?

    I live in Northwestern Illinois.
