Hypagyrtis unipunctata, the one-spotted variant moth or white spot, is a moth of the family Geometridae. The species was first described by Adrian Hardy Haworth in 1809. It can be found from Nova Scotia to Florida, west to Texas, northwest to British Columbia on the North American continent, and is also found in Eurasia.
The wingspan is 20–47 mm. Adults are on wing from April to September in most of North America and from June to July in northern North America. There are one to two generations per year. The larvae feed on the leaves of a wide range of deciduous trees and shrubs, including Amelanchier, Rosa, Prunus, Salix, Populus, Alnus, Betula, Corylus, Fraxinus, Tilia, Ulmus, Quercus and Acer.

Rare
Under 5% of wildlife watchers report a One-Spotted Variant sighting in Toronto on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1296th 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 One-Spotted Variant in Toronto on a given day, so our monthly data shows no clear season.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most One-Spotted Variant sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 3 cities where we can rate One-Spotted Variant sightings, Toronto ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Washington (United States, under 5%) and New York City (United States, under 5%).
Same family: Geometridae
The closest relatives of the One-Spotted Variant that you can see in Toronto (family Geometridae, Geometer Moths) are Chickweed Geometer Moth (about 10%), Pale Beauty (about 10%) and Single-Dotted Wave (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the One-Spotted Variant is recorded against all the insects logged in Toronto (7 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.
