GBIF citizen-science records
It is estimated from how often the Imported Long-Horned Weevil is recorded against all the insects logged in Toronto (96 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.
