Australian painted lady

The Australian painted lady (Vanessa kershawi) butterfly is mostly confined to Australia,[1] although westerly winds have dispersed it to islands east of Australia, including New Zealand.[2] Debate surrounds the taxonomy of this species. Some believe that the Australian painted lady should be a subspecies of the painted lady (Vanessa cardui) due to the similarity in lifestyle and behaviour. Furthermore, the painted lady is found around the globe, but Australia is the only location in which it varies enough to be considered a separate species.[3]

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.[3][4] During spring, adult butterflies migrate south in large numbers from northern states of Queensland and New South Wales.[5] 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.[6]

Despite urbanization and invasive plants altering its habitat, populations of Australian painted ladies have not been significantly impacted by these changes.[7]
