It is the 182nd most-seen of the 256 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.

GBIF citizen-science records
It is estimated from how often the Single-Lined Emerald is recorded against all the insects logged in Calgary (8 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.
