Rare
Under 5% of wildlife watchers report a Celery Fly sighting in Vienna on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 724th 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.
April
In that month about 10% of wildlife watchers report a Celery Fly in Vienna on a given day, against under 5% in May to March, the lowest months.
6th of 6
Of the 6 cities where we can rate Celery Fly sightings, Vienna ranks 6th at under 5%. The best odds are in London (United Kingdom, about 10%), Istanbul (Turkey, about 10%) and Liverpool (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Celery Fly 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.
