Great Mormon Swallowtail | Papilio memnon PUPAE
Papilio memnon, commonly known as the Great Mormon, is a large and visually striking butterfly belonging to the family Papilionidae. Native to South and Southeast Asia, this butterfly is known for its remarkable sexual dimorphism and polymorphism, particularly in females.
Males are typically black with blue iridescence and simpler wing patterns, while females exhibit a wide range of forms that often mimic other unpalatable butterfly species, such as the common rose (Pachliopta aristolochiae), a strategy known as Batesian mimicry. The hindwings of Papilio memnon are sometimes adorned with tails, though this characteristic varies between individuals and subspecies.
With a wingspan of 12–15 cm, the Great Mormon is among the largest butterflies in its range. Its larvae feed on plants of the citrus family (Rutaceae), making it a familiar sight in gardens and orchards. The caterpillars are green with white markings, providing excellent camouflage amongst foliage.
Papilio memnon thrives in diverse habitats, including forests, gardens, and urban areas. Its adaptability, vivid coloration, and intriguing variations have made it a favorite among butterfly enthusiasts.
