Ideopsis hewitsonii

Unknown

Overview

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

Ideopsis hewitsonii faces severe population decline primarily due to rapid deforestation and habitat fragmentation across its Southeast Asian range. The species' dependence on specific host plants makes it particularly vulnerable to forest conversion for palm oil plantations and agricultural development. Climate change compounds these pressures by altering the distribution of its larval food plants and disrupting seasonal flight patterns.

Threat summary

Habitat

This butterfly inhabits primary and secondary tropical rainforests across Southeast Asia, particularly favoring forest edges and clearings where its host plants in the Apocynaceae family thrive. It requires intact forest corridors to maintain connectivity between fragmented populations.
