Japanese beetles
Iridescent lawn destroyers
Japanese beetles are invasive insects native to Japan that feed destructively on ornamental plants, fruit trees, and crops.
The adults are metallic green with copper-colored wings; the larvae are white grubs that damage lawns by eating grass roots.
They became a major agricultural pest in North America after arriving in the early twentieth century.
