Rare
Under 5% of wildlife watchers report a Marbled Yellow Pearl sighting in Copenhagen on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 424th most-seen of the 476 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
In that month about 10% of wildlife watchers report a Marbled Yellow Pearl in Copenhagen on a given day, against under 5% in September to July, the lowest months. That is one of Copenhagen's wettest months, with about 85 mm of rain against 35 mm in April.
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.
5th of 7
Of the 7 cities where we can rate Marbled Yellow Pearl sightings, Copenhagen ranks 5th 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 Copenhagen (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.
