Something this year is attacking plants that are not usually bothered by insects. My achillea are being defoliated and there is serious munching damage on Cranesbill geranium, heuchera, monarda and columbine. I would have suspected JB since 'tis the season, but I haven't seen any on the plants and they're not usually stealthy. Potato beetles have replaced the jb floating in the water bucket but I have not seen any of them on the plants either. Any ideas?
