The Coconut Beetle (Rhynchophorus) is a species of muzzle beetle also known as Asian coconut beetle or sago beetle. Adult beetles are relatively large, ranging between two and five centimeters long, and usually rusty red color, but many color variants exist and are often misidentified as distinct species. Coconut beetles commonly attack coconut leaves, often also called rhino beetles because they have such bulge rhinoceros horns. The losses incurred in the form of damage to the point of growing coconut plants as a place where adult beetles infiltrate inside. As a result, the umbut and the leaf will become damaged which marked the coconut leaves into triangular shape. The emerging beetle will begin to fly at dusk or at night to the crown of the coconut leaf and towards the tip of the stem and then to grow to the point of growing. The pest of the coconut beet belongs to the Coleoptera Order, an insect that undergoes a perfect metamorphosis that passes through the stadia of eggs, larvae, pupae, and imago. This insect egg is white, the shape is first oval, then round with a diameter of approximately 3 mm. These eggs are placed by the female insects in a good and safe place (eg in decaying coconut trees), after 2 weeks these eggs hatch. Stadia eggs range from 11-13 days, on average 12 days.
