About Arctia parthenos Harris, 1850
Arctia parthenos, commonly called the St. Lawrence tiger moth, is a moth species belonging to the family Erebidae. This species was first described by Thaddeus William Harris in 1850. It is native to boreal regions of North America, with a range extending from Alaska to Labrador, southward to New Mexico and Arizona in the Rocky Mountains, and to North Carolina in the Appalachian Mountains. Its typical habitats include riparian areas and mixed hardwood-conifer forests at middle to high elevations. The forewings of adult moths measure 28 to 33 millimeters in length. Adults are active in flight from late May to early August, producing one generation each year. The caterpillar larvae feed on a variety of plant species, including species of Salix, Alnus, and Betula. This species was previously classified in the genus Platarctia, but was reclassified and moved to the genus Arctia, along with other species that were originally placed in the genera Acerbia, Pararctia, Parasemia, Platarctia, and Platyprepia.
