Japanese beetle |
Popillia japonica |
Broadly oval beetle, 8-11 mm long, and about 5-7 mm wide. Females usually are slightly larger than males. The head and body are dark, metallic green, with darker coppery-green legs. The coppery-brown elytra, which do not quite reach the tip of the abdomen, expose a row of 5 lateral patches of white hairs on each side of the abdomen and a pair of these patches on the dorsal surface of the last abdominal segment. These white patches on the green abdomen distinguish P. japonica from all other beetles that resemble it; Bloomington Monroe County, Indiana, USA. 30.viii.1989 Coll: F.N. Young. |
