Oryctes rhinoceros, also known as coconut rhinoceros beetle, Asiatic rhinoceros beetle, and coconut palm rhinoceros beetle, is a large species of beetle (typically 4–5 cm long), belonging to the rhinoceros beetles subfamily Dynastinae. Oryctes rhinoceros attacks coconut palms and other palms such as the economically important oil palm. It can cause serious damage to the developing fronds (leaves) up to death of the palm. The beetle breeds in decaying palm trunks or other organic matter like sawdust or compost heaps.
The native distribution of this beetle covers most parts of tropical Asia, from India and the Maldives in the west to countries like Myanmar, Thailand, Malaysia, Vietnam, most parts of Indonesia, the Philippines, Taiwan and southern China in the east. Through human activity, it has been accidentally introduced into a larger number of tropical islands in the Pacific starting with Samoa where larvae arrived in 1909 with the soil of rubber seedlings from Ceylon (Sri Lanka). From Samoa, the coconut rhinoceros beetle spread to many others parts of the Pacific. Its distribution range also expanded to several islands in the Indian Ocean, in the Western Pacific...

GBIF citizen-science records
It is estimated from how often the Coconut Rhinoceros Beetle is recorded against all the insects logged in Pune (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
