Introduction

There are about 36 species of Christmas Beetles (family Scarabaeidae) with all but one unique (endemic) to Australia and 21 species found in New South Wales. At least 10 species occur in the Sydney region – more if the Blue Mountains are included. Anoplognathus viriditarsus is the largest of the Sydney Christmas beetles.

Identification

Christmas Beetles have vibrant colours and the adults emerge close to the Christmas period. The larvae are white and C-shaped, similar to those of flower chafers and stag beetles. Discover more in our Christmas Beetle 'how to identify' information page.

Habitat

Christmas Beetles are found in forests and woodlands.

Distribution

Christmas Beetles are found in southern and eastern Australia.


Distribution data sourced from the Atlas of Living Australia

Feeding and diet

Christmas Beetles come into Sydney from surrounding woodland where the adults feed on eucalyptus leaves and the larvae feed on grass roots. Adults can occur in large numbers, sometimes completely defoliating trees.

Conservation status

The total number of Christmas Beetles reported in the Sydney area has declined over the last 30 years as the grassy woodland areas get used up for housing.
