In 3 days ~10%
Hypena bijugalis, the dimorphic bomolocha, dimorphic hypena or toothed snout-moth, is a moth of the family Erebidae. The species was first described by Francis Walker in 1859. It is found in North America from Nova Scotia across southern Canada to Vancouver Island, south over the whole United States to Florida.
The wingspan is 24–31 mm. The moth flies from April to September depending on the location. There are two generations in much of the east. More generations southward. The larvae feed on Cornus sericea and perhaps other Cornus species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Dimorphic Snout sighting in Toronto on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1135th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dimorphic Snout 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 Dimorphic Snout sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dimorphic Snout is recorded against all the insects logged in Toronto (9 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.
