Euploea euphon

Unknown

Overview

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

Euploea euphon faces significant pressure from habitat destruction as tropical forests across its Southeast Asian range are cleared for palm oil plantations, logging, and agricultural expansion. The species' dependence on specific host plants in the Apocynaceae family makes it particularly vulnerable to forest fragmentation, which isolates populations and reduces genetic diversity. Climate change poses an additional threat by altering rainfall patterns and temperature regimes that affect both the butterfly and its larval food plants.

Threat summary

Habitat

Euploea euphon inhabits primary and secondary tropical rainforests across Southeast Asia, particularly favoring forest edges and clearings where its Apocynaceae host plants thrive. The species is also found in disturbed forest areas and plantations that retain sufficient native vegetation to support its lifecycle.
