Rare
Under 5% of wildlife watchers report a Leather Beetle sighting in Vienna on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 643rd 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.
April and September
In those months about 10% of wildlife watchers report a Leather Beetle in Vienna on a given day, against under 5% in May–August and October–March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Leather Beetle sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
17th of 18
Of the 18 cities where we can rate Leather Beetle sightings, Vienna ranks 17th at under 5%. The best odds are in Izmir (Turkey, about 20%), Istanbul (Turkey, about 20%) and Bucharest (Romania, about 10%).
GBIF citizen-science records
It is estimated from how often the Leather Beetle is recorded against all the insects logged in Vienna (18 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.
