Confounding this program is the widespread presence of another scarab beetle on Oahu, the oriental flower beetle, Protaetia orientalis (Gory and Percheron 1833). and 5) only occurrences collected in Hawaii by the CRB response team. An incipient coconut rhinoceros beetle population was recently discovered on the island of Oahu, Hawaii and is currently the target of a large, mutiagency eradication program. Holes in the base of the fronds may be obvious when beetle populations are high (Photo 5). When the leaves unfold the damage is seen as V or wedge-shaped areas missing from the leaflets (Photos 1-4). This approach was applied to different subsets of the available CRB occurrence data including: 1) all available global data (excluding Hawaii) 2) only occurrences within CRB's native range 3) only occurrences in the species non-native range (excluding Hawaii) 4) only occurrences in the species insular non-native range (excluding Hawaii). The adult beetle does the damage, boring into the crown of coconut palms, cutting across young fronds and flowers. It attacks coconut palms by boring into the crowns or tops of the tree where it damages growing tissue and feeds on tree sap. This invasive pest is native to Southeast Asia. This CRB habitat suitability was calculated using a simple bioclim approach where suitability values reflect the proximity of a given location on a map to the median climatic condition across the occurrences considered. The Coconut Rhinoceros Beetle (Oryctes rhinoceros)was first detected in Hawaii in December 2013. This dataset simply describes the suitability of the Hawaiian landscape to CRB spread based on climatic conditions (using mean annual temperature and precipitation) of global and local species occurrences. This pest was first detected in Honolulu in December, 2013, and aresponse was launched. As this invasive is found on the island of Oahu primarily at lower elevations, there are concerns about the species spreading towards high value native habitats at higher elevations and/or to other islands across the state. The oriental flower beetle can be confused with the coconut rhinoceros beetle, Oryctes rhinoceros, a major pest of coconut palms that was first seen in Honolulu. The coconut rhinoceros beetle, Oryctes rhinoceros, is a large scarab beetle which is native to Southeast Asia and is distributed through the Western Pacific Region. The arrival of the coconut rhinoceros beetle (CRB, Oryctes rhinoceros) in Hawaii poses serious threats to endemic palm species, crop species and iconic palm trees across the archipelago.
