With luck
About 10% of wildlife watchers report a Bay Sucker sighting in London on a given day, based on 47 verified sightings from GBIF citizen-science data. It is the 489th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February, July, September–October and December
In those months about 10% of wildlife watchers report a Bay Sucker in London on a given day, against under 5% in January, March–June, August and November, the lowest months.
Among the best
Of the 7 cities where we can rate Bay Sucker sightings, London ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Liverpool (United Kingdom, about 10%) and Athens (Greece, about 10%).
GBIF citizen-science records
It is estimated from how often the Bay Sucker is recorded against all the insects logged in London (47 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.
