With luck
About 10% of wildlife watchers report a Brown Leaf Weevil sighting in Vienna on a given day, based on 91 verified sightings from GBIF citizen-science data. It is the 200th most-seen of the 1406 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
In that month about 20% of wildlife watchers report a Brown Leaf Weevil in Vienna on a given day, against under 5% in June to March, the lowest months.
Among the best
Of the 19 cities where we can rate Brown Leaf Weevil sightings, Vienna ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Sofia (Bulgaria, about 10%), Budapest (Hungary, about 10%) and Turin (Italy, about 10%).
GBIF citizen-science records
It is estimated from how often the Brown Leaf Weevil is recorded against all the insects logged in Vienna (91 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.
