Adult cockchafers typically range from 25 to 30mm. Adult Melolontha melolontha have a dark head with a shiny black pronotum covered by short, closely set hairs. They also have a dull black abdomen and a long, flat pygidium. Eyes are multifaceted, with 5,475 facets per eye, providing very acute vision. Males have longer antennae than females, with a large, fan-like club protruding from each terminus. New wing cases are typically mottled with a white powder. Immature (larval) common cockchafers reach lengths of about 40 to 46mm, and have a dull white body colored black at the abdomenal extremity. Cockchafer grubs curve into an arc and have a large head with strong, grabbing mandibles. In overall appearance grubs are fleshy, elongated, and slightly hairy.
