Rare
Under 5% of wildlife watchers report a Gerdana caritella sighting in Toronto on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 427th most-seen of the 1689 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 Gerdana caritella is recorded against all the insects logged in Toronto (39 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.
