Rare
Under 5% of wildlife watchers report a Common Marble sighting in Saint Petersburg on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 111th most-seen of the 448 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 July
In those months about 10% of wildlife watchers report a Common Marble in Saint Petersburg on a given day, against under 5% in August to May, the lowest months. Those are among Saint Petersburg's wettest months, with about 95 mm of rain a month against 40 mm in February.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Common Marble sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
19th of 22
Of the 22 cities where we can rate Common Marble sightings, Saint Petersburg ranks 19th at under 5%. The best odds are in London (United Kingdom, about 10%), Birmingham (United Kingdom, about 10%) and Liverpool (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Marble is recorded against all the insects logged in Saint Petersburg (24 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.
