SCARABAEIDAE

Scarabaeidae is the chafers and dung beetles family of insects of the order Coleoptera. The members have the three distal segments of the antennae widened on one side to form a characteristic lamellate club. The larvae - known as grubs - develop in soil where they live on roots or are found in dung and other decaying organic matter.
