Strymon avalona

Unknown

Overview

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

Strymon avalona faces severe habitat loss due to urban development and invasive plant species on Santa Catalina Island. The butterfly's dependence on native buckwheat plants makes it particularly vulnerable to habitat degradation and fragmentation. Climate change poses additional risks through altered precipitation patterns that affect host plant availability and butterfly breeding cycles.
