With luck
About 10% of wildlife watchers report a Clepsis dumicolana sighting in Paris on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 228th most-seen of the 916 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April–June and September

Among the best
Of the 9 cities where we can rate Clepsis dumicolana sightings, Paris ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Rotterdam [The Hague] (Netherlands, about 10%), London (United Kingdom, about 10%) and Berlin (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Clepsis dumicolana is recorded against all the insects logged in Paris (34 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.
