Rare
Under 5% of wildlife watchers report a Eupsilia quadrilinea sighting in Tokyo on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 557th 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.
February and November
In those months about 10% of wildlife watchers report a Eupsilia quadrilinea in Tokyo on a given day, against under 5% in March–October and December–January, the lowest months.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Eupsilia quadrilinea sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Eupsilia quadrilinea is recorded against all the insects logged in Tokyo (14 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.
