About Hypagyrtis unipunctata (Haworth, 1809)
Hypagyrtis unipunctata, commonly called the one-spotted variant moth or white spot, is a moth species in the family Geometridae. It was first formally described by Adrian Hardy Haworth in 1809. This species is distributed across North America, ranging from Nova Scotia south to Florida, west to Texas, and northwest to British Columbia; it is also found in Eurasia.
