Japanese beetles have a wide host range that includes many species of fruit and vegetable crops, ornamentals and field crops. Adults are metallic bronze and green with white tufts along the side of the abdomen (Photo 1). This pest is becoming a more common corn and soybean pest in Iowa. Adults started to emerge in late May last year, but the cooler temperatures this year have slowed down development in 2013.
