The North American Painted Lady Migration

Painted Lady

Painted Lady Feeding on Thistle

In North America, the Painted Lady Butterfly, Vanessa, cardui, overwinters in the Mexican plateau. In April and May, Painted Lady Butterflies migrate in large swarms to much of the eastern US and Canada. In 2016, Painted Ladies are common in Indiana. The butterflies find numerous suitable houseplants which expands their geographic range. Two to four generations can develop in spring and summer. In early autumn, Painted Lady Butterflies enter reproductive diapause and once again migrate, this time, south to spend the winter in the warmth of Mexico.
