Peacock Swallowtail or Emerald Swallowtail

Natural Habitat

Tropical and subtropical forests, particularly in Southeast Asia. They are often found in jungle clearings, along forest edges, and in gardens or urban areas where host plants and nectar sources are available.

Diet & Feeding

Adults primarily feed on nectar from flowers, as well as sap from trees, decaying fruit, and sometimes even animal waste or moist soil for minerals. Larvae (caterpillars) are herbivorous and feed on the leaves of specific host plants, which vary by species within the Papilio genus.

Behavior Patterns

Adults are active during the day, commonly seen fluttering around flowers, rotting fruit, or even carrion and animal dung from which they can extract nutrients. The vibrant colors on their wings are often iridescent and change with the viewing angle, an adaptation for display and camouflage. Larvae (caterpillars) feed on host plants, undergoing several instars before pupating. This particular species, like many other butterflies, exhibits a complete metamorphosis life cycle.

Risks & Benefits

Benefits: As pollinators, they contribute to the reproduction of many plant species, supporting biodiversity. Their larvae can be a food source for other animals. They are also highly valued in the ecotourism and conservation industries due to their beauty. Risks: Generally, butterflies pose no risks to humans. While caterpillars can sometimes be agricultural pests, this specific species is not typically known for significant crop damage. Their primary risk is habitat loss due to deforestation and human development.
