5th of 9
Of the 9 cities where we can rate Spindle Ermine Moth sightings, Paris ranks 5th at under 5%. The best odds are in Kharkiv (Ukraine, about 10%), Cologne (Germany, about 10%) and Berlin (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Spindle Ermine Moth is recorded against all the insects logged in Paris (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.
