Rare
Under 5% of wildlife watchers report a Bolbocerodema nigroplagiatum sighting in Tokyo on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 509th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Bolbocerodema nigroplagiatum in Tokyo on a given day, against under 5% in October to August, the lowest months. That is one of Tokyo's wettest months, with about 210 mm of rain against 75 mm in February.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Bolbocerodema nigroplagiatum sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Bolbocerodema nigroplagiatum is recorded against all the insects logged in Tokyo (16 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.
