Rare
Under 5% of wildlife watchers report a Bay Sucker sighting in San Francisco on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 622nd most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Bay Sucker in San Francisco on a given day, so our monthly data shows no clear season.
7th of 7
Of the 7 cities where we can rate Bay Sucker sightings, San Francisco ranks 7th 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 San Francisco (6 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.
