Christmas beetles live in Australia in both rural grasslands and urban areas. They are called Christmas beetles because they are commonly seen during the Christmas season, which falls in the Australian summer.
According to Cosmos magazine, Christmas beetles are a type of scarab beetle. They have a flattened shell that is most often golden brown but can also be black, green, yellow or pink. The beetles swarm to light sources at night, and large numbers are found around street lights and other outdoor lighting. The grub of the Christmas beetle eats grass. The adult beetle eats eucalyptus leaves. Scientists are divided on whether the beetle's numbers are growing or declining.
