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.

GBIF citizen-science records
It is estimated from how often the One-Spotted Variant is recorded against all the insects logged in Great Smoky Mountains National Park (9 verified sightings from 2019 to 2026), 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.
