Yes. Not like any shown in the webpages at http://lepidoptera.butterflyhouse.com.au/geometridae/geometridae-cats.html Please can you rear a couple to get an adult moth for an ID ?
Hi @donhe An update on this caterpillar. It changed colour to green and yellow and grew quite quickly up to about 5.5cm. A week ago it disappeared overnight, I assume it burrowed into the soil at the bottom of the jar. I haven't seen it since. It seemed pretty healthy when I last saw it.
