Rare
Under 5% of wildlife watchers report a Spectacled Nettle Moth sighting in Toronto on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 635th 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 Spectacled Nettle 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 Spectacled Nettle Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae

GBIF citizen-science records
It is estimated from how often the Spectacled Nettle Moth is recorded against all the insects logged in Toronto (24 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.
