The Plain Tiger Butterfly Explained

The plain tiger butterfly (Danaus chrysippus) is a hardy orange-and-black butterfly of the family Nymphalidae that is found across India’s gardens, scrub, farmland and village edges, and its caterpillars feed on milkweed plants that make the adult distasteful to predators. The plain tiger butterfly is one of the easiest Indian butterflies to recognise, and it is a classic “model” species whose appearance is copied by several harmless butterflies.

This explainer covers how to identify the plain tiger butterfly, where it lives, what its caterpillars eat, why it is toxic, which butterflies imitate it, whether it migrates, and how to support it in a garden. Information was last reviewed on 23 October 2026.

Key Takeaways

• The plain tiger butterfly (Danaus chrysippus) is an orange-and-black member of the Danainae subfamily that occurs across most of India, from cities to open countryside.
• Plain tiger butterfly caterpillars feed on milkweed plants such as Calotropis, absorbing cardiac glycosides that make adults unpalatable to birds and other predators.
• The plain tiger butterfly is identified by its bright tawny-orange wings, black-tipped forewings with a white band, and three black spots on the hindwing.
• The female Danaid eggfly (Hypolimnas misippus) imitates the plain tiger butterfly, a textbook case of Batesian mimicry in Indian butterflies.
• The plain tiger butterfly flies slowly and low, and it is often seen in large numbers when milkweed is flowering or when seasonal movements occur around the monsoon.
• The plain tiger butterfly is not considered threatened and is easy to attract to gardens that grow milkweed and nectar flowers.

What Is the Plain Tiger Butterfly?

The plain tiger butterfly is a medium-sized, tawny-orange butterfly with black-and-white wingtips, and it belongs to the Danainae, a group of nymphalid butterflies known for their toxicity and their slow, gliding flight. The scientific name is Danaus chrysippus, first described by Carl Linnaeus in 1758 as Papilio chrysippus.

The English name “plain” distinguishes it from other tigers that carry heavier striping, such as the striped tiger (Danaus genutia) and the blue tiger (Tirumala limniace). In Africa, the species is often called the African monarch because it resembles the monarch of North America, even though the two are separate species.

Among Indian butterflies, the plain tiger butterfly is one of the commonest and most widely photographed. Its confidence around people, its habit of visiting garden flowers and its slow flight make it a favourite for schoolchildren and first-time butterfly watchers.

How Do You Identify a Plain Tiger Butterfly?

A plain tiger butterfly is identified by its bright orange-brown wings, the black forewing tips crossed by a broad white band with white spots, and the black margins edged with white dots. The hindwing carries three black spots arranged in a triangle near its middle, one of the clearest field marks.

Field marks to look for

• Upperside: warm tawny-orange with a black border dotted with white.
• Forewing tip: black with a white diagonal band and white spots.
• Hindwing: three black spots near the centre; underside shows paler colours with similar spots.
• Veins: thin and dark, never heavily marked in black, which separates the plain tiger from the monarch.
• Flight: slow, floating and low, usually just above grass and shrubs.

Males and females

Male plain tigers carry a small black scent pouch on the hindwing, sometimes noticeable as a bump near the spots, and females lack it. During courtship, the male uses a pair of brush-like organs at the abdomen tip to dust the female with pheromones, a behaviour documented in many danaine butterflies.

Where Does the Plain Tiger Butterfly Live in India?

The plain tiger butterfly lives throughout India, in open scrub, farmland, gardens, wasteland, roadsides and forest edges, from the plains to the foothills and lower hills. It avoids dense, shaded forest but is regularly recorded in towns and villages where milkweed grows wild.

Globally, the species has one of the largest ranges of any butterfly, covering large parts of Africa, southern Europe, the Middle East, South and Southeast Asia, and Australasia. The Indian populations are generally continuous, and the butterfly is rarely absent from suitable habitat.

The plain tiger butterfly thrives in disturbed ground because its host plants, such as the roadside shrub Calotropis, tolerate drought and poor soil. This is part of the reason it remains abundant while more specialised butterflies decline.

What Does the Plain Tiger Butterfly Caterpillar Eat?

The plain tiger butterfly caterpillar eats leaves of milkweed-family plants (Apocynaceae, formerly Asclepiadaceae), most often Calotropis gigantea and Calotropis procera, locally known as madar or akwan. It may also feed on Asclepias curassavica (tropical milkweed), Tylophora, Cynanchum and other relatives.

Stages of the life cycle

• Egg: pale, ribbed and dome-shaped, laid singly on the leaves or flower buds of the host plant.
• Caterpillar: smooth, with bold bands of black, white and yellow and three pairs of long black filaments, a clear warning pattern.
• Chrysalis: a compact green or pale case, ornamented with small gold or black markings, hanging from a twig or stem.
• Adult: emerges after roughly one to two weeks, and usually lives a few weeks.

Under warm conditions, development from egg to adult can take around a month, and multiple generations occur each year. Numbers often rise after rain, when fresh milkweed leaves are available.

Why Is the Plain Tiger Butterfly Toxic?

The plain tiger butterfly is toxic because its caterpillars absorb cardiac glycosides, also called cardenolides, from milkweed plants and retain them in their bodies into adulthood. These chemicals taste bitter and can make a predator ill, so many birds learn to avoid the butterfly after one experience.

The strategy is called aposematism: the butterfly advertises its unpleasantness through bright orange colour, bold patterns and slow flight. The slow, unhurried flight is itself a signal that the butterfly does not need to flee, since it is protected chemically and its tough, flexible body can survive an attempted bite.

The level of toxin varies between individuals and depends on the host plant they fed on as caterpillars. Some predators, including a few birds and mice in other regions, have evolved ways to eat part of these butterflies while avoiding the most toxic tissues. Protection is strong but not absolute.

The same milkweed sap is irritating to human skin and eyes. Anyone handling the host plant should wash hands afterwards, and the plant should not be eaten or used for home remedies.

Which Butterflies Mimic the Plain Tiger?

The best-known mimic of the plain tiger butterfly is the female Danaid eggfly (Hypolimnas misippus), a harmless nymphalid whose female form closely copies the colour and pattern of the plain tiger. This is Batesian mimicry, where a palatable species gains protection by imitating a toxic model.

The plain tiger is also part of a Mullerian ring, in which several toxic species resemble one another so that predators learn a single warning pattern. Because each species shares the cost of teaching predators, all of them benefit.

The Danaid eggfly’s male is dark with white spots and looks very different, so the species shows sexual dimorphism. Only the female wears the mimetic colour, which suggests that selection from predators acts more strongly on the egg-laying sex.

How Is the Plain Tiger Different From the Monarch?

The plain tiger butterfly differs from the monarch (Danaus plexippus) mainly in its lack of heavy black veining on the orange wings, its three black hindwing spots, and its smaller size. The monarch has strongly outlined black veins and is native to the Americas, although it has spread to some other regions.

The two species are cousins within the genus Danaus. In India, the monarch is not a regular resident, so an orange butterfly seen in a garden is almost certainly a plain tiger or a striped tiger. Observers who carefully check the hindwing spots and the vein pattern can separate these species even in a quick photograph.

Does the Plain Tiger Butterfly Migrate?

The plain tiger butterfly makes seasonal movements across India, and large numbers sometimes travel together, especially around the monsoon, although its movements are less spectacular than those of the tiger and crow butterflies in the Western Ghats. Observers report increased numbers after rains and during flowering of milkweed.

Research on butterfly migration in India remains patchy, and the exact routes and timing of plain tiger movements are not fully mapped. In other parts of the world, plain tigers have been documented crossing deserts and seas, and they can reach islands far from the mainland.

Because the species can disperse widely, populations often recolonise areas quickly after droughts, floods or habitat disturbance. This gives it a strong ability to recover and is one reason it remains common.

How Can You Attract Plain Tiger Butterflies to a Garden?

You can attract plain tiger butterflies to a garden by growing milkweed host plants such as Calotropis or Asclepias curassavica, along with nectar flowers such as lantana, tridax and pentas, and by avoiding pesticides. Without milkweed, adults will visit for nectar but will not breed.

• Plant Calotropis in a sunny corner, or tropical milkweed in pots or beds.
• Add nectar flowers that bloom through the year, such as lantana and marigold.
• Avoid chemical sprays, since caterpillars are sensitive to insecticides.
• Leave some leaf damage on milkweed; it signals that caterpillars are feeding.
• Prune tropical milkweed in the cooler months so that new growth stays fresh.

Gardeners should wear gloves when pruning milkweed because its latex can irritate skin. Native Calotropis is usually the better choice than introduced milkweeds, because it fits local ecology and requires little care.

Why Does the Plain Tiger Butterfly Matter in India?

The plain tiger butterfly matters in India because it is a common, visible example of how plants, caterpillars and predators interact through chemistry, and it is an ideal species for teaching mimicry and migration. It also serves as an indicator of weedy, open habitats that support many other insects.

The butterfly pollinates a range of flowers as it feeds, and its caterpillars are part of the food web, although they are far less palatable than most insects. School projects, butterfly counts and citizen-science platforms often start with the plain tiger because it is easy to spot and identify.

Bottom Line

The plain tiger butterfly is an orange, milkweed-feeding danaine that is toxic to many predators and widespread across India. Planting Calotropis or other milkweed and skipping pesticides is the simplest way to keep it in gardens and farmland.

Frequently Asked Questions

What is a plain tiger butterfly?

The plain tiger butterfly (Danaus chrysippus) is a medium-sized orange-and-black butterfly of the family Nymphalidae that is widespread across India. Its caterpillars feed on milkweed plants, which makes the adults distasteful to predators. It is one of the most common butterflies in Indian gardens and open country.

Is the plain tiger butterfly poisonous?

The plain tiger butterfly is toxic to many predators because it stores cardiac glycosides taken from milkweed in its body. These chemicals taste bitter and can make birds ill, so they learn to avoid it. The butterfly is not dangerous to humans who simply handle it, but milkweed sap can irritate skin.

What does the plain tiger caterpillar eat?

The plain tiger caterpillar eats the leaves of milkweed-family plants, most often Calotropis gigantea and Calotropis procera, known as madar or akwan. It also feeds on tropical milkweed (Asclepias curassavica), Tylophora and Cynanchum. These plants provide both food and the chemicals that protect the butterfly.

Which butterfly mimics the plain tiger?

The female Danaid eggfly (Hypolimnas misippus) is the best-known mimic of the plain tiger butterfly. It is harmless but copies the plain tiger’s orange and black pattern, which is called Batesian mimicry. Predators that avoid the plain tiger tend to avoid the mimic as well.

How can I tell a plain tiger from a monarch?

A plain tiger lacks the heavy black veins on its orange wings that a monarch shows, and it has three black spots on each hindwing. The plain tiger is also smaller. The monarch is native to the Americas and is not a regular resident of India.

Does the plain tiger butterfly migrate?

The plain tiger butterfly makes seasonal movements across India, often around the monsoon, but it is not as famous for mass migration as the tiger and crow butterflies of the Western Ghats. Its routes and timing are not fully mapped. The species can disperse widely and recolonise areas quickly.
