In 3 days ~10%
Pseudohermonassa bicarnea, the pink-spotted dart, is a moth of the family Noctuidae. The species was first described by Achille Guenée in 1852. It is found in eastern North America, and as far west as south-central Saskatchewan and central North Dakota, south to western North Carolina. It has recently been recorded from Tennessee.
The wingspan is 32–43 mm. Adults are on wing from July to October. There is one generation per year. The larvae probably feed on Glyceria maxima and Glyceria canadensis. Older records list Vaccinium, Betula populifolia, Taraxacum officinale, Acer and meadowsweet as food plants. Wikipedia →

Rare
Under 5% of wildlife watchers report a Pink-Spotted Dart sighting in Toronto on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1410th 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 Pink-Spotted Dart 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 Pink-Spotted Dart sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Pink-Spotted Dart is recorded against all the insects logged in Toronto (6 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.
