Grubs of the invasive Coconut Rhinoceros beetle (Oryctes rhinoceros) were found at a Hawaiʻi Island residence, likely transported within store-bought soil or compost products. These beetles are known for boring into unopened fronds of palms to feed on sap, eventually killing the “tree” (technically a perennial flowering plant). On Hawaiʻi Island, these invasive beetles pose a serious threat to our five endemic species of loulu palms, of which three are already designated as endangered or critically imperiled. Please help prevent the spread of these beetles in your area by reporting any sightings of grubs or beetles to the state’s toll-free Pest Hotline: (808) 643-PEST (7378).
