Only Calgary, in our data
Calgary is the only city on Wallace's Line with enough records to rate Northern Spreadwing sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Northern Spreadwing is recorded against all the insects logged in Calgary (32 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.
