Cotinis nitida, commonly known as the green June beetle, June bug or June beetle, is a beetle of the family Scarabaeidae. It is found in the eastern United States and Canada, where it is most abundant in the South. It is sometimes confused with the related southwestern species figeater beetle Cotinis mutabilis, which is less destructive.
The green June beetle is active during daylight hours. The adult is usually 15–22 mm (0.6–0.9 in) long with dull, metallic green wings; its sides are gold and the head, legs and underside are very bright shiny green. Their habitat extends from New Brunswick to Georgia, and as far west as California, with possible population crossover in Texas with their western cousin, the figeater beetle.
The green June beetle is a part of the Scarabaeidae family, with defining characteristics such as modified forewings called elytra sinuate, and a prominent mesosternum. The scutellum is covered by the prothorax attached to the base node. The Cotinis genus is separated by the male species having a small horn on the lower portion of the face (clypeus).
