Rare
Under 5% of wildlife watchers report a Catocala puerpera sighting in Vienna on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 698th 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.
August
In that month about 10% of wildlife watchers report a Catocala puerpera in Vienna on a given day, against under 5% in September to July, the lowest months. That is one of Vienna's wettest months, with about 85 mm of rain against 40 mm in February.
4th of 4
Of the 4 cities where we can rate Catocala puerpera sightings, Vienna ranks 4th at under 5%. The best odds are in Budapest (Hungary, about 10%), Kyiv (Ukraine, under 5%) and Bucharest (Romania, under 5%).
GBIF citizen-science records
It is estimated from how often the Catocala puerpera is recorded against all the insects logged in Vienna (15 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.
