The painted lady butterfly (Vanessa cardui) is the most widely distributed butterfly in the world, found on every continent except Antarctica and Australia. During migration, the painted lady species travels a phenomenal 9,000-mile round trip from tropical Africa to the Arctic Circle. The painted lady caterpillar, which can be purple to yellow-green with black blotches and a black head, has six eyes, although it cannot see very well.

Painted lady caterpillars have six eyes but cannot see very well
The painted lady caterpillar is the larval stage of the painted lady butterfly. It takes about 3–5 days for the caterpillar to hatch from the egg, and it will then eat and molt for another 10–12 days, growing hundreds of times its original size. During this time, the caterpillar's skin will get too tight, triggering a hormone (ecdysone) that regulates the molting process. A caterpillar changes its skin about four times before it's fully grown and ready to enter the chrysalis stage.
The caterpillar uses silk from its spinneret to secure itself and build its chrysalis. It weaves silk tents and develops in a silk nest. Once it pupates (becomes a chrysalis), it will take another 8–10 days until the butterfly emerges. The caterpillar's old body liquefies and then reassembles as a butterfly.
Painted lady caterpillars are purple to yellow-green with black blotches and a black head. They have six eyes and six legs that are jointed to the body, although it looks like they have more. The other appendages that you see from the middle to the back are not jointed and are called pro-legs, which means "false legs."

They have six legs, but the front legs are not used for walking
Caterpillars in their larval stage have six eyes, but they cannot see very well. They also have six legs, but unlike the adult Painted Lady butterfly, the front legs of a caterpillar are not used for walking.
The Painted Lady butterfly, or Vanessa cardui, is the most widely distributed butterfly in the world and can be found on every continent except Antarctica and Australia. It has a four-stage life cycle: egg, caterpillar, chrysalis, and adult. The caterpillar stage lasts for about 10 to 12 days, during which the caterpillar eats and moults, growing hundreds of times its original size.
The Painted Lady caterpillar may be purple to yellow-green with black blotches and a black head. It develops inside a silk nest or tent made from silk spun by the caterpillar itself. The adult Painted Lady butterfly has a wingspan of about two and a quarter to three inches. Its wings are orange-brown with black near the tips of the forewings, which include white spots. The underside of the wings is mottled with grey, brown, and black, and there are four small eyespots near the edge of each hindwing.
The front legs of the Painted Lady butterfly are reduced and not used for walking. This is a common feature among butterflies, and the reason why you may only see two pairs of legs on each butterfly. The first pair of legs is typically tucked in near the head and can be difficult to spot.
The Painted Lady butterfly is a migratory species, travelling up to 100 miles per day at speeds of up to 30 miles per hour. It has over 100 host plants, including thistle, hollyhock, and mallow.

Caterpillars eat 200 times their birth weight in under two weeks
Caterpillars of the painted lady butterfly, or *Vanessa cardui*, have six eyes. However, their vision is quite poor. Painted lady caterpillars weave silk tents and develop in silk nests. They are voracious eaters, consuming 200 times their birth weight in under two weeks. This is an important stage in the caterpillar's growth, as it will increase its body mass by 1,000 times or more.
The larval stage of the painted lady butterfly is about 5 to 10 days, during which the caterpillar will eat and molt. After hatching from the egg, the caterpillar will eat and molt for another 10 to 12 days, growing hundreds of times its original size. The painted lady caterpillar's exoskeleton is made of a biomaterial called chitin, which does not stretch with growth. As the caterpillar grows, its skin gets too tight, triggering the release of the hormone ecdysone, which regulates the molting process.
The painted lady caterpillar changes its skin about four times before it is fully grown and ready to enter the chrysalis stage. During this process, the caterpillar does not just shed its skin; it also digests and reabsorbs most of it. The caterpillar uses silk from its spinneret to secure itself and build its chrysalis. Once it pupates, it will take another 8 to 10 days until the butterfly emerges.
The painted lady butterfly is the most widely distributed butterfly in the world, found on every continent except Antarctica and Australia. It has a wingspan of two and one-fourth to nearly three inches. Its forewing is pointed, and the upper side of the wings is orange-brown with black near the tips of the forewings. The underside of the wings is mottled with grey, brown, and black, and there are four small eyespots near the edge of the hindwing.

They shed their exoskeletons and digest and reabsorb their skin
A painted lady caterpillar has six eyes, but it cannot see very well. The caterpillar stage is the second phase in the painted lady's four-stage life cycle: egg, caterpillar, chrysalis, and adult. During the larval stage, which lasts about 5 to 10 days, painted lady caterpillars eat voraciously, increasing their body mass by up to 1,000 times. As the caterpillar grows, its skin, or exoskeleton, becomes too tight. This triggers the release of a hormone called ecdysone, which regulates the molting process.
The painted lady caterpillar sheds its exoskeleton periodically through a process called molting. This process occurs about four times before the caterpillar is fully grown and ready to enter the chrysalis stage. During molting, the caterpillar not only sheds its skin but also digests and reabsorbs most of it. The exoskeleton, also known as a cuticle, is made of a biomaterial called chitin, which provides exceptional toughness to protect the caterpillar's soft insides. However, due to its strength, chitin cannot stretch with the caterpillar's growth, necessitating the molting process.
The molting process is divided into distinct phases, with the period between two moltings referred to as an "instar." For example, after shedding its skin for the first time, the caterpillar enters the second instar. The painted lady caterpillar's ability to shed, digest, and reabsorb its skin is a remarkable adaptation that allows it to accommodate its rapid growth during the larval stage.
In addition to shedding its skin, the painted lady caterpillar also undergoes other transformations. During the larval stage, the caterpillar's body colour can range from purple to yellow-green, with black blotches and a black head. It weaves silk tents and develops within a silk nest. The caterpillar's diet consists of leaves from various host plants, including thistles, hollyhocks, and mallows. The duration of the caterpillar stage is approximately 10 to 12 days, during which it not only feeds but also undergoes molting.

Painted lady caterpillars weave silk tents and nests
Painted lady caterpillars have six eyes, but they cannot see very well. They undergo a four-stage life cycle: egg, larva (caterpillar), pupa (chrysalis), and adult. During the caterpillar stage, they weave silk tents and nests.
The process of weaving these silk tents and nests is part of the caterpillar's preparation for the next stage of its life cycle. Once it is ready to pupate, the caterpillar creates a pupa and remains in this state for 7 to 10 days. During this time, the old body liquefies and then reassembles as a butterfly. The chrysalis will become clear when the butterfly is about to emerge, with its wings visible.
The painted lady butterfly (Vanessa cardui) is the most widely distributed butterfly in the world, found on every continent except Antarctica and Australia. They are known for their occasional migration in the spring, reaching speeds of up to 30 mph and covering about 100 miles per day.
