Rare
Under 5% of wildlife watchers report a Violet Leaf Beetle sighting in Prague on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 281st most-seen of the 724 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Violet Leaf Beetle in Prague on a given day, against under 5% in September to June, the lowest months. Those are among Prague's wettest months, with about 80 mm of rain a month against 30 mm in February.
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.
4th of 6
Of the 6 cities where we can rate Violet Leaf Beetle sightings, Prague ranks 4th 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 Prague (19 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.
