Rare
Under 5% of wildlife watchers report a Bay Sucker sighting in Paris on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 430th most-seen of the 916 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 to June
In those months about 10% of wildlife watchers report a Bay Sucker in Paris on a given day, against under 5% in July to March, the lowest months.
6th of 7
Of the 7 cities where we can rate Bay Sucker sightings, Paris ranks 6th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), Athens (Greece, about 10%) and London (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Bay Sucker is recorded against all the insects logged in Paris (17 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.
