Rare
Under 5% of wildlife watchers report a Black-Spot Chestnut sighting in Vienna on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1028th most-seen of the 1406 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.
January and March
In those months about 10% of wildlife watchers report a Black-Spot Chestnut in Vienna on a given day, against under 5% in February and April–December, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Black-Spot Chestnut 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.
Among the best
Of the 3 cities where we can rate Black-Spot Chestnut sightings, Vienna ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Prague (Czechia, under 5%) and Berlin (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-Spot Chestnut is recorded against all the insects logged in Vienna (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.
