Grasshoppers Attract Beetles?

I thought last year would be the end of the carnage in my yard, never to happen again. Overnight, blister beetles stripped an entire clematis vine. They also ate up an Anemone Hupehensis ‘September Charm” in the middle of a shade garden and didn't touch any other specimens. Tried diatomaceous earth which didn’t work very well so I reluctantly resorted to some chemical insect spray. I thought I had eliminated them and the plants started to recover, but the beetles came back two weeks later chewing on both the same plants. Little did I know that this attack was related to the number of grasshoppers I had the year before!
