Lichen on the wall?

I found this tiny Phasmid (about 7 cm in length) hanging onto the wall of our house late yesterday afternoon.    Extatosoma tiaratum is known to sometimes mimic lichen as a camouflage at an early instar, however as our house wall is not covered in lichen it looked very exposed and vulnerable.

With the light rapidly fading we had trouble getting a satisfactory photo.  A second attempt after dark with a torch as well as the camera flash has yielded better results.  I haven’t adjusted the colour at all – it really does look quite green.

After the photo session we moved it onto a plant so it had a better chance of avoiding attack by predator.  This morning it was back on the underside of the eaves;  although the plant may have looked an okay place to us, it apparently wasn’t considered suitable by the Phasmid.
