Protaetia formosana

Origin: Taiwan

Size: Approximately 20–30 mm in length

Difficulty (Keeping): Beginner to Intermediate; adapts well to stable tropical conditions

Breeding Difficulty: Intermediate; breeds consistently when larvae are provided with nutritious decaying substrate and adults are maintained warm and well-fed

Temperature: Keep within 22–27°C

Humidity: Moderate to high; maintain slightly moist substrate conditions while avoiding stagnant wet conditions

Ventilation: Moderate ventilation is recommended to maintain airflow while preserving humidity

Diet: Adults feed on soft fruits, beetle jelly, and sugary liquids. Larvae require decaying hardwood substrate rich in white rot material

Habitat Setup: Use a tropical-style enclosure with deep substrate consisting of fermented flake soil or decomposed hardwood substrate for larvae. Adults benefit from cork bark, climbing surfaces, and good airflow

Additional Notes: Protaetia formosana is a colourful flower beetle species appreciated for its metallic appearance and active daytime behaviour. Adults are frequently observed feeding openly and are suitable for both display and breeding setups
