Australian Painted Lady Butterfly

I saw this beautiful little butterfly in our front yard in Roma. The third shot is blurry but it's the only shot I managed to get with the wings open to display the bright orange. Adult butterflies of this species migrate in large numbers in spring from northern regions on the east coast of Australia towards the south-west. According to Wikipedia, the 1889 migration was so large that trains were unable to generate sufficient traction because of the large numbers of butterflies resting on the tracks!
