The painted lady butterfly (Vanessa cardui) is a cosmopolitan traveler with vibrant wings featuring a mosaic of orange, black, and white. It is the most widespread of all butterflies in the world, found throughout Europe, Asia, Africa, North America, and Central America. Females lay their eggs on host plants, and these plants provide essential nutrients for the growth and development of painted lady caterpillars.

What You'll Learn
- Thistles, characterised by prickly stems and purple flowers, are a common choice
- Mallows, with their cup-shaped flowers and soft, lobed leaves, are favoured
- Alfalfa and clover are legumes in the Fabaceae family, offering vital nutrients
- Adult painted ladies feed on nectar from tall plants, including blazing star and cosmos
- Females lay eggs on the undersides of leaves to protect them from predators and weather
Thistles, characterised by prickly stems and purple flowers, are a common choice
The female Painted Lady butterfly lays its eggs on the underside of the leaves of the host plant, usually about 5 to 7 days after emerging. The eggs are small, pinhead-sized, and greenish, often laid singly, and protected from predators and extreme weather by their colour and placement.
Thistles provide ample nutrition for Painted Lady caterpillars, making them an ideal host plant. The caterpillars feed voraciously on the leaves of the thistle, consuming large quantities of foliage as they grow and develop. They go through five instars, shedding their skin several times as they outgrow it, before pupating on the host plant.
In addition to thistles, Painted Lady caterpillars also favour plants from the Malvaceae family, particularly mallows (Malva), which are known for their soft, lobed leaves and cup-shaped flowers. Various legume species within the Fabaceae family, such as alfalfa (Medicago sativa) and clover (Trifolium), are also favoured by Painted Lady caterpillars for their vital nutrients.
By choosing thistles and other preferred host plants for egg-laying, Painted Lady butterflies ensure their caterpillars have access to the necessary nutrients for growth and development, ultimately supporting their transformation into adult butterflies.

Mallows, with their cup-shaped flowers and soft, lobed leaves, are favoured
Painted Lady butterflies have a preference for plants in the Asteraceae family, such as thistles, when it comes to laying their eggs. However, another favoured host plant family is the Malvaceae family, with mallows being particularly favoured.
The female butterflies lay pale green, pinhead-sized eggs on the leaves of various host plants, usually on the underside to protect them from predators and extreme weather. The eggs hatch in 3 to 5 days, and the emerging caterpillars feed voraciously on the host plants, growing rapidly and moulting several times as they outgrow their skin.
Mallows, belonging to the Malvaceae family, provide the necessary nutrients for caterpillar development and their eventual metamorphosis into adult butterflies. The lush foliage of mallows makes them an ideal choice for Painted Lady butterflies, ensuring the healthy growth and survival of their offspring.
In addition to mallows, Painted Lady caterpillars also favour legumes within the Fabaceae family, such as alfalfa and clover. These legumes offer vital nutrients that support the progression of caterpillars towards adulthood. The preference for mallows and legumes highlights the specific requirements of Painted Lady butterflies for their offspring's development and survival.

Alfalfa and clover are legumes in the Fabaceae family, offering vital nutrients
Painted Lady butterflies (Vanessa cardui) are known for their vibrant wings, featuring a beautiful mosaic of orange, black, and white. They are the most widespread of all butterflies in the world, found throughout Europe, Asia, Africa, North America, and Central America. These butterflies have a unique courtship ritual, where males patrol and use their keen eyesight to spot potential mates. After mating, females lay pale green, pinhead-sized eggs on the leaves of various host plants.
Painted Lady caterpillars exhibit a diverse appetite, feeding on a range of host plants that offer essential nutrients for their growth and development. Among the favored host plants for these caterpillars are thistles, known for their prickly stems and distinctive flower heads, often purple in color. Thistles belong to the Asteraceae family, providing ample nutrition for the caterpillars.
Another favored host plant family is Malvaceae, with mallows being particularly favored due to their lush foliage and cup-shaped flowers. The soft, lobed leaves of mallows support the healthy development of Painted Lady caterpillars. Additionally, various legume species in the Fabaceae family, such as alfalfa (Medicago sativa) and clover (Trifolium), are favored by Painted Lady caterpillars. These legumes are characterized by their nitrogen-fixing abilities and compound leaves with small, clustered flowers. Alfalfa and clover, as members of the Fabaceae family, offer vital nutrients that are essential for the growth and development of Painted Lady caterpillars, ensuring their successful progression toward adulthood.
Adult Painted Lady butterflies primarily feed on nectar from a wide variety of flowering plants, acting as important pollinators. They are drawn to nectar-rich flowers, especially those that are 3-6 feet high, such as blazing star, cosmos, New England aster, and Mexican sunflower. These taller plants provide the ideal feeding height for the butterflies. The selection of host plants for egg-laying and larval feeding is of utmost importance, as it directly impacts the health and metamorphosis of Painted Lady caterpillars into their adult butterfly form.

Adult painted ladies feed on nectar from tall plants, including blazing star and cosmos
The female painted lady butterfly lays small, greenish, pinhead-sized eggs on host plants, usually on the underside of leaves to protect them from predators and harsh weather conditions. The painted lady caterpillars, or larvae, then hatch and feed on the leaves of these host plants. They exhibit a preference for thistles, mallows, and various legumes, which offer essential nutrients for their growth and development.
Adult painted lady butterflies, on the other hand, feed primarily on nectar from flowering plants. They are generalist feeders, known to visit over 100 different kinds of plants, making them important pollinators. However, they show a preference for nectar-rich flowers from tall plants, particularly those in the Asteraceae family, which are 3-6 feet high.
Among the favored tall plants for adult painted ladies are blazing star, cosmos, New England aster, Joe-pye weed, Mexican sunflower, purple coneflower, and zinnias. These plants provide a rich source of nectar, which is the primary food source for adult painted ladies.
In addition to these tall plants, adult painted ladies also visit other nectar-producing flowers, such as butterfly bush (Buddleia), heliotrope, anise hyssop, marigolds, scabiosa, sedums, sweet William, and Verbena bonariensis. They are attracted to the nectar offered by these plants and play a crucial role in pollination during their visits.
The preference for tall plants, such as blazing star and cosmos, among adult painted ladies, ensures they can easily access the nectar while also enjoying the open spaces these plants often inhabit.

Painted lady butterflies have a preference for laying their eggs on the undersides of leaves to protect them from predators and harsh weather. The eggs are pinhead-sized and pale green, turning brown before hatching. Females lay their eggs on a variety of host plants, with a particular preference for plants in the Asteraceae family, such as thistles. Thistles have prickly stems and often purple flower heads. They are a good choice for egg-laying because they provide ample nutrition for painted lady caterpillars, supporting their development.
In addition to thistles, painted lady butterflies also favour plants in the Malvaceae family, especially mallows. Mallows have showy, cup-shaped flowers and soft, lobed leaves. The lush foliage of mallows provides a nutritious feast for caterpillars, contributing to their healthy growth.
