Overview

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

The Oak Cosmet faces significant pressure from habitat degradation due to oak woodland fragmentation and urban development across its limited range. Climate change poses an additional threat through altered precipitation patterns that affect the moisture-dependent oak ecosystems this species requires. Agricultural conversion of oak woodlands and intensive forest management practices have further reduced suitable habitat availability.

Threat summary

Habitat

The Oak Cosmet inhabits mature oak woodlands and mixed oak forests, typically in areas with dense canopy cover and rich leaf litter. This species shows a strong association with specific oak species and requires stable moisture conditions found in well-established woodland ecosystems.
