A street you’ve never walked on before. A building you’ve never noticed until today. Ironic scribbles unseen by the casual observer. A lens allows one to see more.
Every fine line on the face... every face, has a story to talk about.
And that's why face reading is perhaps more intersting than book reading:)
An old scribble from the early 90ties. AC Cobra was one of my favorite cars.
Have a nice week!

Title: Dodg’em
Subtitle: Go where you like… If you can
3D mural painting as part of the 2018 edition of street art festival Pow Wow Long Beach with support of Thinkspace Gallery. Created on the side of the Rowan Bradley Building Downtown Long Beach California.
Long Beach Pike was an amusement park from early 1900.
After some decades of fun and entertainment, the Pike was officially closed and demolished in 1979. Lots of history disappeared. I wanted to revive some of that history by painting a 3D mural of a garage with an old bumper car from the early days. Dodg’em was the famous bumper car ride in the Pike.
I was overwhelmed by all the memories from many spectators.
Once upon a time there was a monotypic Genus of moth, Ogmograptis, held responsible for these scribbles on the bark of some Eucalypt trees. Apparently doing no significant harm, the moth layed an egg which developed into a caterpillar that burrowed down, chewed away at the cambium and then just disappeared. These trees typically have decorticating bark which, when shed, revealed the enigmatic scribbles.
Now we know there are 14 species, that they undergo a number of moults in their tunnelling, that they turn about face eating their way back through the yummy callous material laid down by the tree in response to the invasion. Once the caterpillar is big enough it burrows out, drops to the ground and pupates to start the whole thing over again.
I haven't done due diligence on the ID of this tree, that's not my thing, but it is probably a Eucalyptus rossii, or Scribbly Gum, given the distribution of host trees for these moths. That ant is included for scale.
Jesse drew this on a napkin at Applebee's Feb. 23. He and his dad were picking on each other, as usual, and Jesse drew a picture of his dad with stink lines coming off of him and flies buzzing around him. The figure off to the right is supposed to be me laughing at him.
Eucalyptus haemastoma, Scribbly gum.
Scribbles made by the larvae of a scribbly gum moth, Ogmograptis. They are apparently fussy as to tree...

My new project for the evenings. Just sitting and scribbling ...how relaxing :o)
I will post the progress...

Can you read this?
Such ‘scribbles’ on scribbly gums are an icon of the Australian bush, but until recently very little was known about the cause of these distinctive scribbles. It is now known that they are made by the larvae of certain types of moth as they feed under the top layer of various types of gums (eucalypts) before hatching into moths. The trees then shed their outer layer of bark, revealing the scribbles. For more, see www.csiro.au/Outcomes/Environment/Biodiversity/Scribbly-g...
This happened to be on our 9.5km each way walk from Mt Oberon to Sealers Cove, Wilsons Prom, but such scribbles can be seen everywhere in Australia.
A bagworm like the one I found the other day, but this time it looks like it's chewing along the scribbly gum's scribbles. Surely this isn't what makes them...
Update: I contacted the CSIRO after reading their fact sheets, and it turns out that this bagworm doesn't actually make the scribbles. From their return email:
(Max Day, CSIRO) Because I am the person who has been trying to understand the scribbly gum moth story, Julie Carter forwarded your email to me. As you said, you have a truly remarkable photo. So I feel sorry to have to say that the bag moth doesn't make the scribble. In fact, the scribble moth larva is very small and tunnels just beneath the epidermal cells of the tree trunk. The scribble only becomes obvious when the bark is shed during the hot months.
We have collected larvae from several species of eucalypts and bred the moths. They are small and inconspicuous. There are a number of specimens in the Australian National Insect Collection in Canberra. Only one of the species has been described, but one of my colleagues plans to describe others when she can find the time.
The bag moths belong to a different family and are much larger.
What is interesting in your photo is that the bag moth larva appears to be feeding on the scribble, something we have never seen before. So I was delighted to see your photo and will now review the Fact Sheet to try to make sure that it doesnt give the wrong impression of how the scribble is formed.
Many thanks to the people at the CSIRO for this update in their research.
