It is specialized on willow (Salix) hosts and is notable for its dark coloration and tendency to form dense colonies on twigs and branches. The species has been documented across North America and is frequently observed by naturalists.
Purshivora insignita
Purshivora insignita is an aphid species in the family Aphididae, tribe Macrosiphini. It is associated with host plants in the genus Purshia (bitterbrush), from which its generic name is derived. The species is known from western North America. It is a specialist feeder with a narrow host range.
