Popillia japonica
popillia japonicaJapanese beetles display a brilliant metallic green thorax and copper-brown wing covers, fringed with distinctive white tufts of hair along their abdomen. These highly social pests gather in large numbers to skeletonize foliage, leaving behind lace-like remains of leaves on roses, grapes, and lindens. While their underground larvae devastate turfgrass by chewing roots, the adults use powerful pheromones to summon hundreds of companions to a single feeding site.
