The Coconut rhinoceros beetle (Oryctes rhinoceros) is a destructive pest species that primarily targets coconut palms and other palm species. Native to Southeast Asia, it has spread to many tropical and subtropical regions worldwide, including Hawaiʻi. The beetle was first detected on the island of O'ahu in December 2013. Adult beetles are large, usually dark brown or black, with a characteristic horn on their heads. They feed on the tender tissues of coconut palms, causing damage to growing tips, frond bases, and even the heart of the palm. This feeding activity weakens the palm, making it more susceptible to other pests and diseases and ultimately leading to stunted growth, reduced yield, and in severe cases, palm death.
