What You'll Learn
Caterpillars have six eyes
The Painted Lady butterfly (Vanessa cardui) is one of the most widespread butterfly species, found on every continent except Australia, Antarctica, and South America. It is admired for its striking patterned wings, featuring a beautiful mosaic of orange, black, and white. The underside of the wings mimics the pattern of the topside but with softer, more muted colours, providing camouflage when the butterfly is at rest.
The Painted Lady butterfly has a four-stage life cycle: egg, caterpillar, chrysalis, and adult. The caterpillar stage is the second stage of the Painted Lady butterfly's life cycle. Upon hatching from eggs, the larvae emerge as caterpillars. Painted Lady caterpillars are black with spiky bristles and yellowish stripes or spots. They feed on host plants, growing rapidly and shedding their skin several times (moulting) as they outgrow it. Caterpillars have six eyes, but they cannot see very well.
Caterpillars have a set of simple eyes known as stemmata, which are capable of detecting light and movement but cannot form images. These eyes are crucial for the caterpillar's survival, allowing it to navigate its surroundings and sense potential threats. As the caterpillar grows and moults, its eyes also grow and change, adapting to its changing vision needs.
During the caterpillar stage, Painted Lady caterpillars feed voraciously on a variety of host plants, including thistles, mallows, common nettles, and viper's-bugloss. They have a broad host plant range, which contributes to their adaptability and success as a widespread species. The caterpillar stage is a critical period for the Painted Lady's growth and development, as they rapidly increase in size and prepare for the next stage of their transformation.
After the caterpillar stage, the Painted Lady caterpillars pupate and enter the chrysalis stage, where their old bodies liquefy and then reassemble as butterflies. This remarkable transformation showcases the intricate life cycle of the Painted Lady butterfly and highlights the complex changes these creatures undergo.

Adult butterflies have two eyes
Adult Painted Lady butterflies have two eyes. The Painted Lady butterfly (Vanessa cardui) is one of the most widespread butterfly species, found on every continent except Australia, Antarctica, and South America. They are admired for their striking orange, black, and white patterned wings, and their impressive flying capabilities.
Painted Lady butterflies are renowned for their long-distance migratory flights, with some populations migrating from North Africa to the Arctic Circle in Europe and Asia, and from Mexico to Canada in North America. They can reach speeds of up to 20 miles per hour and can travel up to 100 miles per day with the right wind.
The lifecycle of the Painted Lady butterfly includes four stages: egg, caterpillar, chrysalis, and adult. It takes about 3-4 weeks to go from egg to adult. The adult butterfly typically lives for 3-4 weeks in the wild. Painted Ladies are not territorial; males roam widely in search of females, using their keen vision to spot potential mates.
The Painted Lady butterfly's adaptability to a variety of environments, migratory behaviour, rapid reproduction, tolerance to environmental variation, and high dispersal ability have contributed to its success as a widely distributed and beloved butterfly species.
The adult Painted Lady butterfly has a special tube called a "proboscis" just below its eyes. This tube remains curled up until the butterfly needs to feed. When the butterfly lands on a nectar source, it stretches out the proboscis to suck up nectar.

Butterflies taste with their feet
Butterflies, including the Painted Lady butterfly, are unique insects with many interesting traits. One such trait is that they taste with their feet. Butterflies have no mouth and instead have a proboscis that is used like a straw to sip nectar. When a butterfly lands on a flower, its feet act as taste organs that tell the butterfly if the bloom contains nectar. If its feet don't sense any nectar, the butterfly flies away in search of another bloom to land on.
The feet's taste receptors also tell the butterfly if a plant's leaves are food for its larvae. If so, the female butterfly lays eggs on the leaves. This is important for the species' survival, particularly as Painted Ladies are migratory and must ensure they reproduce before they die or undertake long journeys.
Butterflies are not the only insects with taste receptors in unusual places. Crickets and locusts have taste receptors in their ovipositors, an organ that deposits eggs, so they can detect whether the dirt they are using as a nursery is good for their offspring. Parasitoid wasps can do a similar taste test with their antennae, and also perform antennae drumming on the surface of eggs where they might lay their eggs.
In addition to tasting with their feet, butterflies smell and hear with their antennae. In fact, insects can pick up on scent with their antennae, legs, and even their genitals. Some moths have a kind of ear, called a tympanum, on their abdomen that can detect the echolocation of bats hunting them.

They can reach speeds of up to 20 mph
Painted Lady butterflies are known for their impressive flying capabilities. They can reach speeds of up to 20 mph, an ability that is advantageous for long-distance travel. This is due to their large, strong wings relative to their body size, and their highly efficient flight muscles, which allow them to sustain rapid wing beats for extended periods. Their wings are also designed with intricate patterns of veins that provide structural support and flexibility for efficient flight.
The Painted Lady is a long-distance migrant, known for undertaking journeys of thousands of miles. They spread northwards from the desert fringes of North Africa, the Middle East, and Central Asia, recolonising mainland Europe and reaching Britain and Ireland. Some years, they are abundant in gardens and other flowery places in late summer. They are widespread across the United States and Canada, especially in the spring and summer, and can often be found in open fields, meadows, and gardens.
The Painted Lady's adaptability to a variety of environments is attributed to its broad host plant range, migratory behaviour, rapid reproduction, tolerance to environmental variation, and high dispersal ability. These traits enable it to thrive in diverse ecosystems worldwide.
The Painted Lady butterfly's scientific name is Vanessa cardui, and it is one of the most widespread butterfly species. It is found on every continent except Australia, Antarctica, and South America. In Australia, V. cardui has a limited range, but its close relative, the Australian painted lady (V. kershawi), ranges over half the continent.
Painted Lady butterflies are easily recognised by their orange-brown wings with black and white spots. Their wings are distinctively scalloped, with five small submarginal eyespots on the hindwings.

They are found on every continent except Antarctica
The Painted Lady butterfly (Vanessa cardui) is one of the most widespread butterfly species in the world, found on every continent except Antarctica. They are particularly known for their striking patterned wings, featuring a beautiful mosaic of orange, black, and white. These medium-sized butterflies are renowned for their long migratory flights, with some populations migrating from North Africa to the Arctic Circle in Europe and Asia, and from Mexico to Canada in North America.
In 2023, scientists discovered that Painted Ladies spend winters in tropical Africa, moving from the semiarid savannas of Senegal on Africa's west coast to Kenya in the east, before heading north in January or February. This migratory pattern is believed to be influenced by heavy rains like El Niño, which may impact the availability of their larval host plants.
Painted Ladies are migratory and must reproduce before they die or undertake long journeys. They have a unique system of continuous mating throughout all seasons, including winter. During European migrations, they mate and lay eggs upon arrival in the Mediterranean in the spring. In the United States, those migrating north experience poor mating conditions, and many have limited breeding capabilities.
The Painted Lady's resilience in adapting to dramatic changes in climate, food availability, and urban development serves as a reminder of our interconnectedness with nature. However, they require human attention to continue thriving. Protecting their breeding grounds and nectar sources is crucial for their survival.
