@RobParnell : how did you find it : on the ground ? tunneling into wood : what type of tree? Please can you rear it in captivity to get the adult moth for ID of the species?
Sorry Don, the photo is nearly 2 months old. I think it came out of some wood I was chopping. I'll be sure to rear the next one I find. What should I feed it?
In general : one feeds a larva on what it was feeding on when found, so if it was boring into wood, give it some bits of the same wood, i.e. from the same tree species. In this case : the legs look wrong for a Lepidoptera larva. I think it is a beetle larva. I have reared some of those too, and got interesting adult beetles, that are quite easy to identify, as are adult moths..
