Rare
Under 5% of wildlife watchers report a Eurasian Hemp Moth sighting in Beijing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 349th most-seen of the 401 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.
August and November
In those months about 10% of wildlife watchers report a Eurasian Hemp Moth in Beijing on a given day, against under 5% in September–October and December–July, the lowest months.
Among the best
Of the 3 cities where we can rate Eurasian Hemp Moth sightings, Beijing ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Seoul (South Korea, under 5%) and Tokyo (Japan, under 5%).
GBIF citizen-science records
It is estimated from how often the Eurasian Hemp Moth is recorded against all the insects logged in Beijing (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.
