Zygophlebia major

Unknown

Overview

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

Zygophlebia major faces severe pressure from deforestation and habitat fragmentation across its limited range in tropical montane forests. Agricultural expansion and logging activities have significantly reduced the quality and connectivity of its specialized forest habitat. Climate change poses an additional threat by altering the temperature and humidity conditions essential for this species' survival in high-elevation ecosystems.

Threat summary

Habitat

Zygophlebia major inhabits tropical montane forests at elevations between 1,200-2,400 meters, requiring specific microclimate conditions of high humidity and stable temperatures. The species is typically found in undisturbed primary forest with dense canopy cover and rich leaf litter layers.
