The painted lady is a butterfly.
It lives in many places. It flies very far to find food. These butterflies love bright flowers. They can even fly over the sea!

The painted lady is a special butterfly.
It lives in almost every part of the world. These butterflies fly very long ways. They fly to find food and warm weather.
Sometimes, heavy rain helps them grow. Rain makes more plants grow for them to eat. They use the sun to help them fly straight. These butterflies are very good at traveling far.
The painted lady is a very special butterfly.
It is the most widespread butterfly in the world. You can find them on every continent except Antarctica and South America.
These butterflies are famous for their long trips. This is called migration. They fly to find warm weather and food. Some butterflies even fly across the ocean! They use a solar compass to stay on track. This means they use the sun to help them fly in a straight line.
Rain plays a big part in their lives. Heavy rain in the desert makes many plants grow. These plants are food for the baby butterflies. When there is lots of food, millions of butterflies may fly at once. In one place, a billion butterflies were seen in a single trip!
Adult butterflies drink nectar from flowers. The mothers lay many eggs on plants. They choose plants that have lots of food nearby. This helps them make many new babies. The babies, called larvae, hide in silk nests on leaves. This helps them stay safe from birds and spiders.
The painted lady is a very famous butterfly.
It is the most widespread butterfly species in the world. You can find them on almost every continent. They live everywhere except Antarctica and South America.
In Australia, they stay near places like Bunbury and Rottnest Island. Other close relatives live in different places. The American painted lady and the West Coast lady are related to them. These butterflies are important because they travel so far.
These butterflies are famous for their amazing migrations. Migration is when animals move from one place to another. They often fly to find warmer weather or more food.
In the spring, they fly from North Africa to Europe. Some even fly from the Red Sea to Turkey. In California, they usually fly toward the north-west. They seem to fly toward rain to find more food. Heavy desert rain helps plants grow for their babies. This can cause millions of butterflies to move at once.
Scientists have studied these travelers for a long time. For many years, experts debated how they moved. They wondered if the babies made the trip back south. Now, research shows they can make a huge round trip. They do this in up to six steps or generations.
A group called the Radar Entomology Unit found they fly very high. This is why people seldom see them migrating. A project called The Worldwide Painted Lady Migration helps us learn more. This project uses science from many people to track them.
There are many interesting facts about how they live. In 2018, about a billion butterflies were seen in Israel.
In 2019, millions flew across Southern California after heavy rain. Some butterflies even fly across the ocean! Researchers found specimens in French Guiana that came from Africa. These butterflies use a solar compass to fly straight. This means they use the sun to find their way. They need a clear view of the sky to work. Without the sun, they cannot find the right direction.
Painted ladies have a very busy life. Adult butterflies drink nectar from flowers for energy. Mothers lay many eggs on plants that have lots of nectar. This helps their babies find food quickly. The babies, called larvae, hide in small silk nests. This keeps them safe from birds, ants, and spiders.
Their eyes are also very special. They can see ultraviolet, blue, and green light. However, they cannot see the color red. This is different from other butterflies like the monarch. People even breed them for schools and weddings.
The painted lady, known scientifically as *Vanessa cardui*, is the most widespread butterfly species on Earth.
It can be found on every continent except Antarctica and South America. In North America, it was formerly called the cosmopolitan. This butterfly is famous for its incredible ability to travel vast distances. It lives in any temperate zone, including tropical mountains. While it stays in warmer areas as a resident, it often moves to find better conditions. This movement is known as migration.
Migration patterns for the painted lady are highly erratic and do not happen every year.
These movements are often triggered by weather events. For example, heavy winter rains in deserts can cause massive migrations. In March 2019, heavy rain in Southern California led to millions of butterflies migrating across the state. In the 2018-2019 winter, heavy rain caused a migration of an estimated one billion butterflies in Israel. Some scientists believe global climatic events, like El Niño, may also influence these large-scale movements.
To navigate these long journeys, the painted lady uses a solar compass. This is a biological tool that helps the insect maintain a straight flight path. Laboratory studies show that butterflies need a direct view of the sky to orient themselves. When butterflies are isolated from the sun, they cannot find a specific direction. They can also adjust their path based on local weather and topography. This includes responding to strong wind patterns. This flexibility helps them navigate across complex landscapes.
One of the most amazing discoveries involves the painted lady crossing an ocean.
Researchers recently found specimens in French Guiana, which is outside their natural habitat. By analyzing genomes and using isotope tracing, scientists confirmed these butterflies were born in Europe or Africa. Pollen on their bodies matched West African shrubs. The study suggested that favorable trade winds helped propel them across the water. This represents one of the longest insect journeys ever recorded.
Researchers have also studied how these butterflies complete long-distance round trips. For decades, naturalists debated if the offspring of migrants ever returned south. Now, research suggests that British painted ladies do undertake an autumn migration. They complete a round trip from tropical Africa to the Arctic Circle. They do this in a series of steps involving up to six successive generations. The Radar Entomology Unit found that these autumn migrations occur at high altitudes. This high-flying behavior explains why people seldom witness them.
Life cycles and reproduction are also unique for this species.
Painted ladies exhibit a system of continuous mating throughout all seasons. This includes mating during the winter. This behavior is likely linked to their constant migratory patterns. Females often practice oviposition, which is the act of laying eggs. They tend to choose plants that have nectar available for adults. They prioritize the quantity of offspring over the quality of the environment. This high biotic potential helps the species propagate successfully.
While traveling, the larvae, or caterpillars, must stay safe. They feed on various host plants in the Asteraceae family. This includes plants like *Cirsium*, *Carduus*, and *Helianthus*. To avoid predators like birds, wasps, and spiders, the caterpillars hide in small silk nests on leaves. Adult butterflies also use flight and camouflage as defense mechanisms. Their visual systems are also specialized. They have ultraviolet, blue, and green opsins in their eyes. However, unlike monarch butterflies, they lack red receptors and cannot see red light.
