Rare
Under 5% of wildlife watchers report a Marbled Yellow Pearl sighting in Berlin on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 646th most-seen of the 1065 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 and August
In those months about 10% of wildlife watchers report a Marbled Yellow Pearl in Berlin on a given day, against under 5% in July and September–May, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Marbled Yellow Pearl sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 7
Of the 7 cities where we can rate Marbled Yellow Pearl sightings, Berlin ranks 4th at under 5%. The best odds are in Novosibirsk (Russia, about 10%), Amsterdam (Netherlands, about 10%) and Prague (Czechia, under 5%).
GBIF citizen-science records
It is estimated from how often the Marbled Yellow Pearl is recorded against all the insects logged in Berlin (10 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.
