Rare
Under 5% of wildlife watchers report a Violet Leaf Beetle sighting in Berlin on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 949th most-seen of the 1065 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Violet Leaf Beetle in Berlin on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Violet Leaf Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 cities where we can rate Violet Leaf Beetle sightings, Berlin ranks 6th at under 5%. The best odds are in Kyiv (Ukraine, about 10%), Budapest (Hungary, about 10%) and Warsaw (Poland, about 10%).
GBIF citizen-science records
It is estimated from how often the Violet Leaf Beetle is recorded against all the insects logged in Berlin (5 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.
