Oriental beetle

The Oriental beetle (Anomala orientalis, not to be confused with the Japanese beetle) is a beetle about 0.7 - 1.1 cm (0.3 - 0.4 inches) long, with mottled, metallic brown- and black-colored elytra and a similarly-colored thorax and head during the adult stage. During the larval stage the oriental beetle can be identified by the parallel line raster pattern. It is native to Asia and was introduced to North America and has since spread to and become a pest in several mid-Atlantic states. Its invasive range extends from Maine to South Carolina and Wisconsin. In its larval stage, the grub feeds on the roots of grasses while the adults feed on roses, phlox, and petunias. Sex pheromone traps are available to capture and kill the Oriental beetle.
