On a tree

Today’s Prompt: Squiggles

The tree is called a Scribbly Gum. How do the “scribbles” get onto the tree I hear you ask? Well, the female Scribbly Gum Moth lays eggs between layers of old and new bark. The larvae burrow into the new bark and, as the old bark falls away, the feeding trails of the larva are revealed.

The two most common scribbles are zigzag patterns, always doubling back on each other, and sine waves. 

Next time, you see a scribbles on a eucalypt stand back and appreciate the handy work of one of Australia’s first bush “artists.”
