Nigetia formosalis
In 3 days ~10%
Nigetia is a monotypic genus of moths in the family Erebidae. Its only species, Nigetia formosalis, the thin-winged algibelle or thin-winged owlet moth, has a scattered distribution in eastern North America from Ontario to Connecticut, south to Florida and Texas. Both the genus and the species were first described by Francis Walker in 1866.
The wingspan is about 19 mm. There is one generation in the northern parts and two or more in the southern parts of its range. Larvae have been reared on Protococcus species but probably also feed on lichens. Wikipedia →

Rare
Under 5% of wildlife watchers report a Thin-Winged Owlet 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 Thin-Winged Owlet in Toronto on a given day, so our monthly data shows no clear season.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Thin-Winged Owlet 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 Thin-Winged Owlet sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Thin-Winged Owlet that you can see in Toronto (family Noctuidae, Cutworm Moths and Allies) are American Dagger (about 10%), Large Yellow Underwing (about 10%) and Armyworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Thin-Winged Owlet 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.
