Rare
Under 5% of wildlife watchers report a White-Spotted Leafroller Moth sighting in Toronto on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 867th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-Spotted Leafroller Moth in Toronto on a given day, so our monthly data shows no clear season.
Only Toronto, in our data
Toronto is the only city on Wallace's Line with enough records to rate White-Spotted Leafroller Moth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-Spotted Leafroller Moth is recorded against all the insects logged in Toronto (18 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.
