Rare
Under 5% of wildlife watchers report a Pearl Grass-Veneer sighting in Berlin on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 745th most-seen of the 1065 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.
July and August
In those months about 10% of wildlife watchers report a Pearl Grass-Veneer in Berlin on a given day, against under 5% in September to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Pearl Grass-Veneer sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
5th of 5
Of the 5 cities where we can rate Pearl Grass-Veneer sightings, Berlin ranks 5th at under 5%. The best odds are in Helsinki (Finland, about 10%), Essen (Germany, under 5%) and London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Pearl Grass-Veneer is recorded against all the insects logged in Berlin (8 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.
