Nature's Graffiti

Take a closer look at this eucalyptus tree. It's known as a scribbly gum, and despite looking as if the junior school group tried to carve their affections for each other all over it, the zigzag tracks are actually tunnels made by the larvae of a moth. They are interesting because they reflect the life-cycle of the insects. Increases in the tunnel diameter show that the larvae is growing, and the end of the track is where it has stopped burrowing and started to pupate.

Larvae graffiti - how very interesting. The smooth bark of the eucalyptus makes the perfect palate. Did you see any of those little furry animals in the tree eating the leaves?

ytaba36: It's great, isn't it? Nature produces some wonderful images.

Genie: Alas, no sightings of Koalas. They are becoming rather rare to see in the wild, and they are now predicting that they may be extinct in 50yrs time.
