Euploea caespes

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Euploea caespes faces severe population decline primarily due to deforestation and habitat fragmentation across its limited range in Southeast Asian lowland forests. Agricultural expansion and palm oil plantations have eliminated much of its primary forest habitat, while urban development continues to fragment remaining forest patches. The species' dependence on specific host plants makes it particularly vulnerable to habitat quality degradation, as even partially disturbed forests may lack the necessary plant communities for larval development.

Threat summary

Habitat

This butterfly inhabits primary and secondary lowland tropical rainforests, typically below 500 meters elevation. It requires intact forest canopy and understory vegetation that supports its specific host plants from the Apocynaceae family.
