Look for adult beetles in late June to early July, as littleleaf linden begins bloom and Hills of Snow hydrangea is in full bloom. Adults often feed in a group, skeletonizing leaves with only a network of veins remaining when feeding damage is heavy. Larvae damage roots of turf.

Management: Beetles are attracted to plants damaged by feeding, so control damage early. Pheromone traps and bait traps are not recommended as a strategy for trapping out beetles. Traps contain a floral lure to attract female beetles and a pheromone to attract males. It is possible to draw in more beetles from surrounding areas and to have greater damage resulting, particularly if traps become full.
