A beautiful gum leaf mimic moth about 65mm wingspan. Patterns on the wing resemble those of a dry and decomposing eucalyptus leaf as does the overall shape. The behaviour of the moth was even more leaf-like. Initially it was very high on a wall so I touched it with a long stick and instead of flying it simply fell like a leaf to the litter below. It initially landed on it's back revealing similar colours but with 2 darker grey areas near the centre of the wings. Even when touched it refused to attempt flight and would just flip over to lie still on top of the other leaves.
This caterpillar was very well camouflaged in acacia leaves. I found it after noticing frass and working out where it was coming from... right in front of me!
About 40mm long, a real Aussie in vivid green with yellow/gold flecks throughout. Only one set of prolegs and claspers says geometridae. http://lepidoptera.butterflyhouse.com.au/enno/senilis.html
A tricky little spider which I only noticed when it moved onto a green stem from a grey one. Strongly resembling a broken twig node it was about 8mm across it's body.
On twigs of Acacia mearnsii.
