This is a close-up photo using my phone, which is what I have to hand when walking my dog on bush trails. This image, in a similar manner to my previously featured Banksia photo, seems over-detailed (too sharp?) if that makes sense. I must take the camera, rephotograph and compare the shots.
Anyway, back to the subject. This is a section of a Scribbly gum trunk. I’ve always wondered what makes these amazing track marks and Google tells me:
The scribbly gum is a native Australian eucalyptus tree which is easy to spot because of the distinctive markings along its smooth yellow-gray trunk. These zig-zag tracks or ‘scribbles’ are made by the moth grub as it tunnels between the old and new bark.
What a cool effect.
