The 'scribbles' are made by the larvae of the Scribbly Gum Moth.
they are a wonderful gum tree. Perhaps my favorite gum tree is the Mighty River gum..
I love the Root structures!
That reminds me Simon, I have an old photo somewhere of a River Gum in a dried up Todd River outside Alice Springs ...
I love those scribbles. How deep into the wood do those go? Are they just on the surface? They look a little like a spalt, which is also a black line in wood caused by worms, then mold, but it is not quite as scribbly.
"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." I just copied that from the too dark link in my first comment, Red Mojo ;)
Will the tree die because of the moths' writings? Or do they enrich the tree and make them grow better. Are the moths parasites or commensals? Is this a symbiotic relationship?
We identify the Scribblies because of the moth marks Ces! They live together in harmony :) The moths are only 1-2 mm in length!
Ahhh I just posted a comment that scribbly gums were my favourite... and here they are..Anony your a legend... :)
I think they are a lot of Aussie's favourite Abbey :)
