Did You Know? Incredible Christmas Beetle Facts

One of the most interesting Christmas beetle facts is that you can easily find them in Australia during the winter season

Christmas beetles, or Christmas bugs,  live in the woodlands or forests and are found all over Australia, except for the desert regions. These Australian bugs species are known as Christmas beetles because they are abundant in urban and rural areas close to Christmas. There a total of 35 species of this Christmas beetle, eight of this species are found in Sydney. They are attractive in looks due to their iridescent color, which can look different from different angles. They have compound eyes, two pairs of wings, antennae, and adult Christmas beetles come with six pairs of legs. They are metallic brown, green or yellow and green in color.

They belong to the scarab bug Family (Scarabaeidae) in the Order of Coleoptera. Australia is a developed country, and it continues to grow rapidly. Because of this urbanization, the beetles are losing their home. Australian Christmas beetles are the largest of all other species of bugs. The Christmas beetle adults feed on eucalyptus leaves, and the larvae feed on grassroots. The life cycle of a Christmas beetle is between one and two years. Anoplognathus is the genus of this bug. After the rain softens the soil, adults fly to mate and feed on the nearest plant, then female beetles lays their eggs. A female beetle can lay between 20 and 40 eggs at once. In the early summer or spring season, the eggs are laid on the soil and after that, larvae emerge. Anoplognathus viridiaeneus is the scientific name of this bug species. They are one of the largest beetles in the beetle family and grow up to be around 0.7-1.1 in (2.3 cm) in length. They are present in large quantities throughout the summer months.

Sydney, and NSW (New South Wales), particularly, used to be filled with swarms of these bugs. But, reduction in the size of Cumberland Plain woodland has ruined their habitat. Entomologist Dr. Chris Reid, from the Australian Museum, ascribes the drop in sightings to it being a drier than normal spring season, especially along the New South Wales coast. Chris Reid (from Australian Museum Research Institute) says, on the disappearance of Christmas bugs, that the reason behind the decrease of the beetles is urbanization. In other words, since trees are being chopped off to build residential areas, the beetles own habitats are being destroyed. Christmas bugs’ main food source is eucalyptus leaves, but these trees have also declined due to the rising populace.
