With luck
About 10% of wildlife watchers report a Japanese Stag Beetle sighting in Tokyo on a given day, based on 589 verified sightings from GBIF citizen-science data. It is the 30th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Japanese Stag Beetle in Tokyo on a given day, against under 5% in October to April, the lowest months.
2nd of 5
Of the 5 cities where we can rate Japanese Stag Beetle sightings, Tokyo ranks 2nd at about 10%. The best odds are in Nagoya (Japan, about 20%).
GBIF citizen-science records
It is estimated from how often the Japanese Stag Beetle is recorded against all the insects logged in Tokyo (589 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.
