About Eosphoropteryx thyatyroides Guenée, 1852
Eosphoropteryx thyatyroides, commonly called the pink-patched looper moth or pink-tinted beauty, is a moth species belonging to the family Noctuidae. This species was first formally described by Achille Guenée in 1852. In North America, its distribution ranges from Nova Scotia and northern Ontario in the north, southward to Minnesota, Michigan, Ohio, and along the Appalachian Mountains from Maine to eastern Tennessee and western North Carolina. To the west, the species is found from central Alberta and southern British Columbia, extending south in the Cascade Range to southern Oregon, and in the Rocky Mountains to northern Idaho. The wingspan of adult moths measures 31 to 38 mm. Flight periods for adults vary by location: they are active from July to August in Alberta, and from June to early August through mid-October in Great Smoky Mountains National Park. The larvae of this moth feed on Thalictrum dioicum and Thalictrum polygamum.
