The adult cockchafer beetle

Lookalike

Melolontha melolontha has a similar-looking but smaller relative that appears later in the year called the summer chafer, Amphimallon solstitialis. On average, summer chafers are about 13mm long, half the size of cockchafers. 

This beetle also has a hairy body under reddish-brown wing cases but has long, sparsely arranged hairs (when seen with a hand lens or magnifying glass).
