Commonly seen in Sydney gardens, it is an active butterfly moving quickly from flower to flower. Feed on nectar from a variety of flowering herbs.  The caterpillars have adapted to feed on a variety of plants including the introduced Camphor Laurel (Cinnamomum camphora). The green larvae rest on the upperside of the leaves and can be difficult to see. If the plant is disturbed, you are more likely to smell them before you see them. Many caterpillars in this family (Papilionidae) have an 'osmeterium', which looks like a fleshy horn that pops up from a slit behind their head and emits a strong smell. In this species the osmeterium is yellow, but in other species it may be red. This species is found as several subspecies all over south-east Asia.
