Rare
Under 5% of wildlife watchers report a Gonia picea sighting in Vienna on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 955th 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.
February and March
In those months about 10% of wildlife watchers report a Gonia picea in Vienna on a given day, against under 5% in April to January, the lowest months.
Among the best
Of the 2 cities where we can rate Gonia picea sightings, Vienna ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Warsaw (Poland, under 5%).
GBIF citizen-science records
It is estimated from how often the Gonia picea is recorded against all the insects logged in Vienna (14 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.
