Japanese beetle
The Japanese Beetle (Popillia japonica) is a beetle about 1.5 cm (0.6 inches) long and 1 cm (0.4 inches) wide (smaller in Canada), with shiny copper-colored elytra and top of thorax and head, which is not very destructive in Japan, where it is controlled by natural enemies, but in America is a serious pest to rose bushes and other plants. It is a weak flyer and drops several centimeters when it hits a wall. Japanese Beetle traps therefore consist of a pair of crossed walls with a bag underneath, and are baited with floral scent, pheromone, or both.
