Larvae feed on roots and can weaken or kill smaller plants. They are whitish, C-shaped, and about 8 mm long when full grown, much smaller than white grubs. They pupate in the upper layers of soil in the spring and change into adults later in the spring or in summer, joining the adults of the previous summer to feed on leaves and fruit.

Cetonia aurata, called the rose chafer or the green rose chafer, is a beetle, 20 millimetres (3 ⁄ 4 in) long, that has a metallic structurally coloured green and a distinct V-shaped scutellum. The scutellum is the small V-shaped area between the wing cases; it may show several small, irregular, white lines and marks.
The grub population consists mainly of first instars in early- to mid-August, second instars by early September, and third instars by mid-September to early October. In frost zones, the grubs feed until November, then move deeper into the soil. In frost-free areas, the larva will feed all winter. Vigorous feeding occurs from March through May.
