With luck
About 10% of wildlife watchers report a Cassida nebulosa sighting in Berlin on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 239th most-seen of the 1065 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 to July
In those months about 10% of wildlife watchers report a Cassida nebulosa in Berlin on a given day, against under 5% in August to March, the lowest months.

Yes
Of the 4 cities where we can rate Cassida nebulosa sightings, Berlin has the highest daily chance: about 10%. Next come Vienna (Austria, about 10%) and Bucharest (Romania, under 5%).
GBIF citizen-science records
It is estimated from how often the Cassida nebulosa is recorded against all the insects logged in Berlin (39 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.
