Idea tambusisiana

Unknown

Overview

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

Idea tambusisiana faces severe pressure from deforestation and habitat conversion across its limited range in the Philippines. The species' dependence on specific host plants makes it particularly vulnerable to forest fragmentation, as adult butterflies require intact forest corridors for movement between breeding sites. Agricultural expansion and logging activities have significantly reduced the quality and connectivity of remaining forest patches.

Threat summary

Habitat

This butterfly inhabits primary and secondary tropical rainforests in the Philippines, particularly areas with dense canopy cover and abundant climbing vines. The species requires forest environments that support its specific host plants from the Apocynaceae family.
