Unfortunately @donhe i didn’t think of it at the time, I don’t know that I would have the knowledge or skill set to do so either. I’ll keep it in mind if we find another! Do you have any info on how to do so?
@BenHarvey : sure :see http://lepidoptera.butterflyhouse.com.au/faqs/care.html For food for a Cossid, try giving it a carrot to bore into. There are published photos of only 7% Aussie moth species. Most caterpillars you find have to be reared to the adult if you want to know it's species.
