Rare
Under 5% of wildlife watchers report a Dotted Chestnut sighting in Vienna on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1090th 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
In that month about 10% of wildlife watchers report a Dotted Chestnut in Vienna on a given day, against under 5% in February to December, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Dotted Chestnut sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 3 cities where we can rate Dotted Chestnut sightings, Vienna ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Prague (Czechia, under 5%) and London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Dotted 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.
