Australian painted lady similar to those in the late summer. Seasonal changes could trigger the development of spring and fall body forms that are ideal for the migration patterns described above. During periods of large migration in Australia, and with the possible help of strong winds, the Australian painted lady migrates across the sea to New Zealand. Multiple occurrences of this butterfly in New Zealand were reported in the 1960s. In the spring of 1968, they appeared on the western coast of New Zealand near the sea, and were unusually abundant.
