Happy ! Today is all about the painted lady (Vanessa cardui), the world’s most widespread butterfly species. Painted ladies belong to Nymphalidae, the brush-footed butterflies. Â
Â
They live on every continent except Antarctica, and only rarely in South America. They use many kinds of open habitats. Temperate-zone painted ladies migrate to warmer regions in cooler months and return for the breeding season. In North America, many overwinter in northern Mexico and return to the U.S. and Canada. They travel great distances every year.Â
Â
They mate continuously, even while overwintering, and have numerous broods annually. Female painted ladies lay eggs on various host plants. They prefer to deposit eggs near nectar-heavy flowers. This lets them increase sugar intake which improves egg production and overall lifespan. Painted ladies follow a typical butterfly life cycle. The caterpillars create silk nests on host plants to protect them while they grow. Â
Â
Like most butterflies, adult painted ladies eat nectar from many flower species. Caterpillars prefer to eat thistle leaves but also consume many asters and other nonwoody plants. One of the reasons that painted ladies are so widespread is because their diet is so variable.Â
Â
While these butterflies are of least-concern conservation status, it is important that we protect and support all native pollinators. They are vital members of their food webs, and we rely on them for pollination. Â
