The Australian painted lady (Vanessa kershawi) butterfly is mostly confined to Australia although westerly winds have dispersed it to islands east of Australia, including New Zealand. The painted lady is found around the world but Australia is the only place in which it varies enough to be considered a separate species. Debate surrounds the taxonomy of this species. Some believe the Australian painted lady should be a subspecies to the painted lady due to the similarity in lifestyle and behaviour. However, due to the distinct genitalia of the males, and variation in colouration, many others consider the Australian painted lady to be a separate species. During spring, adult butterflies migrate south in large numbers from Queensland and New South Wales. To find mates, male Australian painted ladies exhibit territorial behaviour, which involves a male perching on vegetation in a sunny spot on a hilltop, waiting for females to fly by. Despite urbanisation and invasive plants altering their habitat, populations of Australian painted ladies have not been significantly affected by these changes.
