In 3 days ~10%
Euxoa detersa, the rubbed dart, sandhill cutworm or sand cutworm, is a moth of the family Noctuidae. The species was first described by Francis Walker in 1856. It is found in North America from Newfoundland to North Carolina, west to Nebraska, north to Alberta and the Northwest Territories.
The wingspan is 30–35 mm. Adults are on wing from July to October. There is one generation per year. The larvae feed on corn, various grasses, cranberry, saltwort, sea-rocket, various garden crops and commercial grains. The larvae construct burrows to feed on underground portions of host plants. They are considered very destructive in fields planted in sandy soils. Wikipedia →

Rare
Under 5% of wildlife watchers report a Rubbed Dart 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 Rubbed Dart in Toronto on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Rubbed Dart sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Toronto, in our data
Toronto is the only city on Wallace's Line with enough records to rate Rubbed 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 Rubbed Dart 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.
