In 3 days ~20% in a week ~40%
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 →

With luck
About 10% of wildlife watchers report a Eucorynus crassicornis sighting in Manila on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 91st most-seen of the 122 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Eucorynus crassicornis in Manila on a given day, against under 5% in January, March–April, June and August–October, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Eucorynus crassicornis sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 9 cities where we can rate Eucorynus crassicornis sightings, Manila ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Nanjing (China, about 10%) and Hangzhou (China, about 10%).
Same order: Coleoptera
The closest relatives of the Eucorynus crassicornis that you can see in Manila (order Coleoptera, Beetles) are Xylotrupes philippinensis (about 20%), Coconut Rhinoceros Beetle (about 20%) and Variable Ladybird Beetle (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eucorynus crassicornis is recorded against all the insects logged in Manila (7 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.
