Conservation Status

• Population: Generally stable across its range, but local declines can occur due to habitat loss and environmental changes.
• Threats: Habitat destruction, intensive agriculture, and pesticide use are the primary threats.

Conservation Efforts

• Habitat Preservation: Maintaining and protecting meadows, grasslands, and wildflower-rich areas is crucial for their survival.
• Reduced Pesticide Use: Promoting environmentally friendly farming and gardening practices helps protect this and other butterfly species.

Human Interaction

• Observation: A favored species among butterfly enthusiasts and photographers due to its vibrant coloration and active behavior.
• Education: Used in educational programs to highlight the importance of biodiversity and habitat conservation.
