Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Parantica marcia faces severe population declines primarily due to rapid deforestation and agricultural conversion throughout its Southeast Asian range. The species' dependence on specific host plants in the Apocynaceae family makes it particularly vulnerable to habitat fragmentation, as isolated forest patches cannot sustain viable breeding populations. Urban expansion and palm oil plantation development have eliminated critical lowland forest corridors essential for the butterfly's dispersal and genetic connectivity.
Habitat
Parantica marcia inhabits tropical lowland and hill forests up to 1,200 meters elevation, particularly favoring forest edges and clearings where its Apocynaceae host plants thrive. The species requires intact forest connectivity for successful reproduction and dispersal across its fragmented Southeast Asian range.
