Rare
Under 5% of wildlife watchers report a Rosemary Beetle sighting in Vienna on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 838th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rosemary Beetle in Vienna on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Rosemary Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
25th of 25
Of the 25 cities where we can rate Rosemary Beetle sightings, Vienna ranks 25th at under 5%. The best odds are in Liverpool (United Kingdom, about 20%), Manchester (United Kingdom, about 20%) and London (United Kingdom, about 20%).
GBIF citizen-science records
It is estimated from how often the Rosemary Beetle is recorded against all the insects logged in Vienna (12 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.
