Endemic, found in New Zealand and Australia as well as Lord Howe Island and Norfolk Island. Medium-sized butterfly. Now a common urban butterfly here, where the main food plants are species of Parietaria in gardens. Also on endemic nettles (Urtica). Numbers build up through the summer until it can be very common around sources of nectar, like climbing ivy and Buddleia in city gardens.
Most countries around the world have a red admiral; but we are different - as well as having our very own red admiral, we share a yellow admiral with Australia.
If you are looking to breed admirals, Terence Smithers' detailed guide will be invaluable.
