Rare
Under 5% of wildlife watchers report a Eurhadina betularia sighting in Tokyo on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 929th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report a Eurhadina betularia in Tokyo on a given day, against under 5% in January to November, the lowest months. That is one of Tokyo's driest months, with about 85 mm of rain against 250 mm in October.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Eurhadina betularia sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Eurhadina betularia is recorded against all the insects logged in Tokyo (5 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.
