Taxonomy
- Kingdom: Animalia

Description
Parides ascanius is a medium‑sized swallowtail butterfly. Adults possess the characteristic elongated tails on the hindwings typical of Papilionidae. The dorsal wing surfaces are predominantly black with striking iridescent green or blue markings; the ventral side often displays contrasting spots and bands that aid in species identification.
Distribution and Habitat
The species is endemic to Brazil, occurring primarily in the Atlantic Forest biome. It inhabits forest edges, clearings, and secondary growth where host plants are present.
Biology and Ecology
- Host plants: Larvae feed on species of the genus Aristolochia, which contain toxic compounds that confer chemical defense to the caterpillars and adult butterflies.
- Life cycle: Like other swallowtails, the species undergoes complete metamorphosis (egg → larva → pupa → adult). Specific details of its phenology (e.g., number of generations per year) are not comprehensively documented.
Conservation
The International Union for Conservation of Nature (IUCN) has not evaluated Parides ascanius for the Red List, and thus its global conservation status is not formally established. Habitat loss within the Atlantic Forest due to deforestation and urban expansion may affect local populations, but precise population trends are currently undocumented.
