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 New York City on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 740th most-seen of the 1623 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, 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 New York City 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, New York City ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Washington (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the One-Spotted Variant is recorded against all the insects logged in New York City (18 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.
