Graphium megaera
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Graphium megaera faces severe pressure from deforestation and agricultural expansion across its limited range in Southeast Asian lowland forests. The species' dependence on specific host plants makes it particularly vulnerable to habitat fragmentation, as isolated forest patches may not support viable breeding populations. Mining activities and palm oil plantations have accelerated forest conversion in key areas where this swallowtail occurs.
Habitat
This swallowtail butterfly inhabits primary and secondary lowland rainforests, typically below 800 meters elevation. It shows a strong preference for forest edges and clearings where its host plants in the Annonaceae family are most abundant.
