Eucorynus crassicornis is a species of fungus weevil in the beetle family Anthribidae, which was first described in 1801 by Johan Christian Fabricius as Anthribus crassicornis, from specimen(s) collected in Sumatra. It has been found in South Korea (Jeju Island), Japan, Far East Russia, China, Taiwan, Thailand, Malaysia, Singapore, the Philippines, India, and Australia.
In Indonesia, this weevil damages the pods and seeds of the legume crops Crotalaria striata, other Crotalaria species, and those of Leucaena leucocephala. In Kerala, it has been found to be a major destroyer of stored bamboo. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Eucorynus crassicornis is recorded against all the insects logged in Zhuhai [Macau] (9 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.
