Rare
Under 5% of wildlife watchers report a Eurasian Hemp Moth sighting in Tokyo on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 381st 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.
June
In that month about 10% of wildlife watchers report a Eurasian Hemp Moth in Tokyo on a given day, against under 5% in July to May, the lowest months.
Among the best
Of the 3 cities where we can rate Eurasian Hemp Moth sightings, Tokyo ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Seoul (South Korea, under 5%).
GBIF citizen-science records
It is estimated from how often the Eurasian Hemp Moth is recorded against all the insects logged in Tokyo (27 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.
