Blue Chafer

Natural Habitat

Meadows, grasslands, and riverbanks in Europe, often found on flowers and foliage in sunny areas.

Diet & Feeding

Adults feed on the pollen and flowers of various plants, including willows and umbellifers. The larvae live underground and feed on plant roots.

Behavior Patterns

Diurnal, active in warm, sunny weather from late spring to summer. Only the males possess the vibrant, iridescent blue coloration which is structural, not pigment-based. Females are typically a dull brown. They often congregate on flower heads to feed and mate.

Risks & Benefits

Adults contribute to pollination. Larval root-feeding is not typically significant enough to cause major plant damage. The beetle is harmless to humans and is admired for its beauty.
