The adult beetle is 8 to 13 millimeters long.[1] It is metallic green in color with a black or yellow cast.[3] There is a pair of white spots on the inner edges of the elytra. The larva is a creamy white color and measures up to 43 millimeters in length. The first thoracic segment is enlarged. The grub is legless and has a pair of horns on its last abdominal segment.[2] The beetles have an average lifespan of 2 months, but some may live upwards of 5 months.[3]
