About West Coast Lady
The West Coast lady (Vanessa annabella) is one of three North American species of brush-footed butterflies known colloquially as the "painted ladies". V. annabella occurs throughout much of the western US and southwestern Canada. The other two species are the cosmopolitan Vanessa cardui (painted lady) and the eastern Vanessa virginiensis (American painted lady). This species has also been considered a subspecies of the South American, Vanessa carye, and is frequently misspelled as "anabella".From Wikipedia via iNaturalist — article, CC BY-SA.
