With luck
About 10% of wildlife watchers report a Common Marble sighting in Nizhny Novgorod on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 79th most-seen of the 405 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May–June and August
In those months about 10% of wildlife watchers report a Common Marble in Nizhny Novgorod on a given day, against under 5% in July and September–April, the lowest months.
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.

Of the 22 cities where we can rate Common Marble sightings, Nizhny Novgorod ranks 11th at about 10%, level with the leaders once rounded. 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 Nizhny Novgorod (21 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.
