Rare
Under 5% of wildlife watchers report a Marbled Grass-Veneer sighting in Moscow on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 911th most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, 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 Grass-Veneer in Moscow on a given day, so our monthly data shows no clear season.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Marbled Grass-Veneer sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 2 cities where we can rate Marbled Grass-Veneer sightings, Moscow ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Berlin (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Marbled Grass-Veneer is recorded against all the insects logged in Moscow (6 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.
