The Karner blue butterfly is a small, vibrant butterfly known for its striking blue wings. It is primarily found in the northeastern United States and parts of Canada. This species relies on specific habitats, particularly oak savannas and pine barrens, where its caterpillars feed on the leaves of wild lupine plants. The Karner blue butterfly has a unique life cycle, consisting of four stages: egg, larva, pupa, and adult. Conservation efforts are crucial for its survival, as its populations have declined due to habitat loss and fragmentation. Protecting its natural habitats is essential for maintaining this beautiful species.
