About Euphyia intermediata (Guenée)
Euphyia intermediata, commonly known as the sharp-angled carpet, is a moth species belonging to the family Geometridae. Achille Guenée first described this species in 1858. It can be found across the entire continent from coast to coast, covering southern Canada and the northern United States. In the eastern part of its range, it extends south to North Carolina; in the western part, it reaches south to California and Utah, and may also occur in Arizona. Its range extends north to the Northwest Territories and Alaska. Previously, the European species Euphyia unangulata was considered a Holarctic species, so the same name was also used for North American populations of what is now Euphyia intermediata. In 1999, Malcolm J. Scoble and other authors split these populations into two separate distinct species in their work Geometrid Moths of the World. This moth has a wingspan ranging from 21 to 27 mm. Adult moths are active from April to September, and the species produces one generation per year. The larvae of Euphyia intermediata feed on a variety of plant species, including bedstraw, carnation, chickweed, elm, and mustard.
