The Green June Beetle, also known by its scientific name Cotinis nitida, is a species of large, metallic green-colored beetle belonging to the family Scarabaeidae. It is native to the eastern regions of North America, primarily found from Vermont to Florida, and as far west as Texas.
The Green June Beetle is commonly recognized by its vibrant metallic green or golden colored exoskeleton, which often reflects sunlight and gives it a distinct appearance. Adults typically reach a size of 1.25 to 1.5 inches, with a broad, oval-shaped body and a hardened, shield-like structure covering their backs. Their iridescent green coloration serves as protective camouflage among foliage.
These beetles are mainly active during the summer months, with their peak activity occurring in June, hence their common name. They are primarily daytime flyers, with a buzzing flight pattern that often attracts attention. Green June Beetles are frequently found in open areas, meadows, gardens, and orchards, especially those with decaying fruits and vegetables.
The larvae, known as grubs, are white, C-shaped, legless creatures usually found in underground tunnels, feeding on organic matter, plant roots, and decaying organic substances. After spending a variable amount of time in this phase, typically a year or two, the larvae pupate and transform into the adult beetles.
While Green June Beetles are generally considered harmless to humans, they can occasionally cause mild damage to fruit crops or ornamental plants. Despite this, they are also regarded as beneficial insects due to their role in pollination and as a food source for various wildlife species.
