With luck
About 10% of wildlife watchers report a Springtime Dung Beetle sighting in Vienna on a given day, based on 72 verified sightings from GBIF citizen-science data. It is the 213th most-seen of the 1406 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.
April–June and August–September
In those months about 10% of wildlife watchers report a Springtime Dung Beetle in Vienna on a given day, against under 5% in July and October–March, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Springtime Dung Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Springtime Dung Beetle sightings, Vienna ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Budapest (Hungary, about 10%).
GBIF citizen-science records
It is estimated from how often the Springtime Dung Beetle is recorded against all the insects logged in Vienna (72 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.
