Werner's Prepona

Prepona werneri

Unknown

Overview

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

Prepona werneri faces severe pressure from deforestation and habitat fragmentation across its limited range in Central American cloud forests. Mining activities and agricultural expansion have eliminated significant portions of its montane habitat, while climate change threatens to shift suitable temperature and humidity zones beyond the species' elevational range. The butterfly's specialized requirements for specific host plants and microhabitat conditions make it particularly vulnerable to even small-scale habitat modifications.

Threat summary

Habitat

Prepona werneri inhabits pristine cloud forests and montane rainforests at elevations between 800-2000 meters in Central America. The species requires dense canopy cover with high humidity levels and depends on specific understory plants for larval development.
