The garden chafer belongs to the family of Scarabaeidae and is hence closely related to the cockchafer. The beetles are 8-11 mm long, head and neck are glossy green to black. The wing cases are yellow-brown to red-brown and scarcely haired. The sides, the under side and the legs have light hairs. In contrast to other scarabaeid beetles, the body of the garden chafer is relatively flat. Beetles swarm on sunny days between 10:00 and 12:00 o?clock from the end of May to mid June.
