What is the Common Mormon Butterfly?

The Common Mormon butterfly, scientifically known as Papilio polytes, is a swallowtail butterfly species found widely across Asia and Australia. It belongs to the family Papilionidae, which includes some of the largest and most beautiful butterflies in the world. This butterfly is particularly interesting due to the polymorphism seen in its female forms, a clever adaptation for survival.

Key Characteristics

Scientific Name: Papilio polytes
Family: Papilionidae (Swallowtails)
Distribution: Asia and Australia
Habitat: Gardens, open woodland, and agricultural land
Wingspan: 80–120 mm

Why is it Called the Common Mormon?

The name “Common Mormon” comes from the butterfly’s polymorphic nature. Early entomologists, struck by the different forms of the female, likened them to the multiple wives in Mormon polygamous relationships. While the name might seem a bit outdated today, it’s a historical artifact that reflects the scientific understanding (and social norms) of the time.

Identifying the Common Mormon Butterfly

Identifying the Common Mormon butterfly involves looking at several key characteristics, including wing patterns, size, and behavior. The males and females have distinct appearances, which we’ll explore in detail.

Male vs. Female

Males: The male Common Mormon butterfly typically has black wings with white spots. The hindwings feature a row of red crescents along the edge.

Females: This is where it gets interesting! Female Common Mormons exhibit polymorphism, meaning they come in several different forms, each mimicking different species of poisonous butterflies. This mimicry protects them from predators.

Common Female Forms:

Form polytes: This form resembles the male but has larger white spots on the wings.
Form romulus: This form mimics the Common Rose butterfly (Pachliopta aristolochiae) and is black with white patches.
Form stichius: This form mimics the Crimson Rose butterfly (Atrophaneura hector) and is black with red patches.

Detailed Wing Patterns

To accurately identify a Common Mormon, pay close attention to the wing patterns. Here’s a breakdown:

Forewings: The forewings are generally black with white or cream-colored spots. The size and arrangement of these spots can vary.
Hindwings: The hindwings often have a row of red crescents along the edge. In some female forms, the hindwings may have large white or red patches, depending on the species they are mimicking.

Size and Shape

The Common Mormon butterfly has a wingspan of approximately 80 to 120 mm. It is a swallowtail butterfly, meaning its hindwings have distinctive “tails.” The overall shape is elegant and aerodynamic, allowing for swift flight.

Behavioral Clues

Observing the butterfly’s behavior can also help with identification. Common Mormons are active during the day and are often seen fluttering around flowers, feeding on nectar. The males are known to patrol territories in search of mates.

Life Cycle of the Common Mormon Butterfly

Understanding the life cycle of the Common Mormon butterfly provides valuable insights into its development and ecological role. The life cycle consists of four stages: egg, larva (caterpillar), pupa (chrysalis), and adult.

Egg Stage

The female Common Mormon lays her eggs singly on the leaves of host plants. These eggs are small, round, and typically greenish or yellowish in color. The eggs hatch in about 3 to 6 days, depending on environmental conditions.

Larva (Caterpillar) Stage

Once the egg hatches, the larva, or caterpillar, emerges. The caterpillar feeds voraciously on the leaves of its host plant. The Common Mormon caterpillar goes through several instars (stages between molts), each with its own unique appearance.

Early Instars: Young caterpillars are often dark in color and may resemble bird droppings, providing camouflage against predators.
Later Instars: As the caterpillar grows, it becomes green with white or yellowish markings. It also develops a forked, orange-colored osmeterium, a defensive organ that emits a foul odor when threatened.

Pupa (Chrysalis) Stage

When the caterpillar is fully grown, it pupates, forming a chrysalis. The chrysalis is typically green or brown and blends in with its surroundings. This stage lasts about 7 to 14 days, during which the caterpillar undergoes metamorphosis, transforming into a butterfly.

Adult Stage

Finally, the adult butterfly emerges from the chrysalis. The newly emerged butterfly’s wings are soft and crumpled. It takes a few hours for the wings to expand and harden. Once the wings are ready, the butterfly takes flight, ready to reproduce and continue the cycle.

Stage	Description	Duration
Egg	Small, round, greenish or yellowish	3-6 days
Larva (Caterpillar)	Dark in early instars, green with markings in later instars	2-4 weeks
Pupa (Chrysalis)	Green or brown, camouflaged	7-14 days
Adult	Butterfly with distinct wing patterns	2-4 weeks

Habitat and Distribution

The Common Mormon butterfly is widely distributed across Asia and Australia, thriving in a variety of habitats.

Geographical Range

This butterfly can be found in countries such as India, Sri Lanka, China, Japan, Malaysia, Indonesia, the Philippines, and Australia. Its wide distribution is attributed to its adaptability and the availability of its host plants.

Preferred Habitats

Common Mormons prefer habitats such as gardens, open woodland, agricultural land, and urban areas. They are often seen in places with plenty of flowering plants, which provide nectar for the adults.

Host Plants

The Common Mormon caterpillar feeds on a variety of plants, primarily belonging to the citrus family (Rutaceae). Some common host plants include:

Citrus trees (e.g., lemon, lime, orange)
Curry leaf plant (Murraya koenigii)
Limeberry (Triphasia trifolia)

The availability of these host plants is crucial for the survival and distribution of the Common Mormon butterfly.

Attracting Common Mormon Butterflies to Your Garden

Attracting Common Mormon butterflies to your garden is a rewarding experience. By providing the right host plants and nectar sources, you can create a butterfly-friendly habitat.

Planting Host Plants

To encourage Common Mormons to breed in your garden, plant their host plants. Citrus trees and curry leaf plants are excellent choices. Ensure these plants are free from pesticides, as these can harm the caterpillars.

The Mimicry of Female Common Mormon Butterflies

One of the most fascinating aspects of the Common Mormon butterfly is the mimicry exhibited by its female forms. This adaptation is a remarkable example of natural selection and survival strategy.

What is Mimicry?

Mimicry is a phenomenon in which one species evolves to resemble another species. This can provide protection from predators, attract pollinators, or gain other advantages. In the case of the Common Mormon butterfly, the female forms mimic poisonous butterflies to avoid being eaten.

Types of Mimicry

There are two main types of mimicry:

Batesian Mimicry: A harmless species mimics a harmful one. The female Common Mormon butterflies are Batesian mimics, resembling poisonous butterflies like the Common Rose and Crimson Rose.
Müllerian Mimicry: Several harmful species resemble each other. This reinforces the warning signal to predators, making them more likely to avoid all similar-looking species.

Why Mimic Poisonous Butterflies?

Poisonous butterflies, such as the Common Rose and Crimson Rose, contain toxins that make them unpalatable to predators. These butterflies often have bright colors and distinctive patterns that serve as a warning signal. By mimicking these species, female Common Mormon butterflies trick predators into thinking they are also poisonous, thus avoiding predation.

Examples of Mimicry in Common Mormon Females

Form romulus: This form closely resembles the Common Rose butterfly (Pachliopta aristolochiae).
Form stichius: This form mimics the Crimson Rose butterfly (Atrophaneura hector).

Female Form	Mimicked Species	Description
romulus	Common Rose (Pachliopta aristolochiae)	Black with white patches
stichius	Crimson Rose (Atrophaneura hector)	Black with red patches
