Flights of Fancy

Painted lady butterflies rival monarchs in their migratory journeys.

- JILL STAAKE

When you think of butterfly migration, it's probably monarch butterflies that first spring to mind. Their epic journey to Mexico each year has caught the public's imagination, especially as their overwintering grounds have become threatened. But monarchs aren't the only butterflies that travel long distances. The painted lady also migrates, and its journey can be even more spectacular.

One of the most widespread butterflies in the world, the painted lady is commonly found in North America, Europe, Africa, and Asia. In the United States, its range stretches from coast to coast, from sea level to mountains and valleys. Adults feed on flower nectar, while their caterpillars eat a huge variety of host plants, including thistles and mallows. They're unable to withstand freezing temperatures, so when winter comes, painted ladies need to find warmer climates.
