Rare
Under 5% of wildlife watchers report a Marbled Yellow Pearl sighting in Moscow on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 637th most-seen of the 1111 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Marbled Yellow Pearl in Moscow on a given day, so our monthly data shows no clear season.
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.
7th of 7
Of the 7 cities where we can rate Marbled Yellow Pearl sightings, Moscow ranks 7th 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 Moscow (12 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.
