Joiceya praeclara

Unknown

Overview

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

Joiceya praeclara faces severe pressure from deforestation and habitat fragmentation across its limited Atlantic Forest range in southeastern Brazil. Mining activities and urban expansion have destroyed critical breeding sites, while agricultural conversion continues to reduce the remaining forest patches this species depends on. Climate change poses an additional threat by altering the delicate microclimatic conditions required for its larval development.

Threat summary

Habitat

This butterfly inhabits the remaining fragments of Atlantic Forest (Mata Atlântica) in southeastern Brazil, particularly in mountainous regions with dense canopy cover.
