Scribbly gum

Easily identifiable Australian native plants, scribbly gum trees are found throughout NSW coastal plains and hills in the Sydney region. The most distinctive features of this eucalypt are the ‘scribbles’ made by moth larva as it tunnels between the layers of bark.

The scribbly gum is a native Australian eucalyptus tree which is easy to spot because of the distinctive markings along its smooth yellow-grey trunk. These zig-zag tracks or ‘scribbles’ are made by the moth grub as it tunnels between the old and new bark. Every year when the tree sheds the old bark, new markings are revealed.

The scribbly gum generally grows to 15m and produces white flowers in summer, attracting native Australian birds such as honeyeaters.

The scribbly gum is found throughout NSW coastal plains and hills in the Sydney region. Two other species of scribbly gum are found in NSW: eucalyptus racemosa, which is found nearby; and eucalyptus rossii, which is found on the western slopes of NSW.
