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".
Aside from general differences in distribution, V. annabella can be distinguished from the other two painted ladies of North America as follows: Most conspicuously, it lacks obvious ventral eyespots on the hindwings; there are two large ones on V. virginiensis and four small ones on V. cardui. Like the latter, it also lacks a white dot in the pinkish-orange subapical field of the ventral and dorsal forewings. Its upperwing coloration has the purest orange of the three; the American painted lady is usually quite reddish.
A less reliable indicator is the row of black eyespots on the dorsal submarginal hindwing. These are usually of roughly equal size in V. cardui and... Wikipedia →

GBIF citizen-science records
It is estimated from how often the West Coast Lady is recorded against all the insects logged in Death Valley National Park (7 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
