Scribbly Gum
Ogmograptis scribula. The eggs of this moth are laid between the old and new season's bark of gum-barked eucalypt trees. As the larva burrows between the bark layers it leaves a tunnel which is revealed when the old bark falls away. Like all insect larvae, that of Ogmograptis scribula increases in size periodically and these changes can be seen as a widening in the tunnel revealed as a scar on the bark surface.
"Eucalyptus haemastoma", commonly known as scribbly gum, is a species of tree that is endemic to the Sydney region. It has white or silvery grey bark, lance-shaped or curved adult leaves, flower buds in groups of between nine and fifteen, white flowers and conical or hemispherical fruit. It is one of three eucalypts with prominent insect scribbles in the bark.
