With luck
About 10% of wildlife watchers report an Alcides trifidus sighting in Nagoya on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 104th most-seen of the 195 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
April–May, July and October
In those months about 20% of wildlife watchers report an Alcides trifidus in Nagoya on a given day, against under 5% in August and November–March, the lowest months.
Yes
Of the 3 cities where we can rate Alcides trifidus sightings, Nagoya has the highest daily chance: about 10%. Next come Tokyo (Japan, about 10%) and Seoul (South Korea, under 5%).
Same family: Curculionidae
The closest relatives of the Alcides trifidus that you can see in Nagoya (family Curculionidae, True Weevils) are Two-Banded Japanese Weevil (about 20%) and Eugnathus distinctus (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Alcides trifidus is recorded against all the insects logged in Nagoya (12 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.
