Rare
Under 5% of wildlife watchers report a Lunar Marbled Brown sighting in Paris on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 743rd most-seen of the 916 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.
March
In that month about 10% of wildlife watchers report a Lunar Marbled Brown in Paris on a given day, against under 5% in April to February, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Lunar Marbled Brown sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 4 cities where we can rate Lunar Marbled Brown sightings, Paris ranks 4th at under 5%, level with the leaders once rounded. The best odds are in London (United Kingdom, under 5%), Birmingham (United Kingdom, under 5%) and Prague (Czechia, under 5%).
GBIF citizen-science records
It is estimated from how often the Lunar Marbled Brown is recorded against all the insects logged in Paris (6 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.
