Eucalyptus rossii (sometimes called Western Scribbly Gum or White Gum) is a smooth-barked eucalypt found on the Western side of the Great Dividing Range in Eastern Australia - and through much of the Molonglo High Plains. The markings on the tree are made by the larvae of a moth - secret writing that trace the growth of the larvae. The trails start small and gradually deepen as the larvae grow – sometimes the paths backtrack, retracing older paths. The path ends where the larvae pupates. The trails are revealed when old bark falls away from the tree.
