Adult green June beetles are about an inch long, with dull metallic green wings, gold or brownish highlights on head and sides, and shiny green underparts. In flight, they make a loud buzzing noise, much like that of a bumblebee.
Green June beetles belong to a large family of beetles called scarabs. As with other scarabs, they are oval, stout, and have clubbed antennae with segments that can press tightly together or can be fanned open like a feather.
The larvae of green June beetles are cream-colored, C-shaped grubs that live underground. The heads are dark brown, and they have three pairs of legs.
