American Painted Lady
Encyclopedia
The American Painted Lady or American Lady (Vanessa virginiensis) is a butterfly
found throughout North America
.
Vanessa virginiensis lives in flowery habitats, usually in mountains. The larvae feed on various Asteraceae
, especially the cudweeds of genus Gnaphalium
. All stages of the life cycle can be found throughout temperate North America as well as Madeira
and the Canary Islands
. Occasionally individuals can be found as far as south-west Europe
.
The largest spot in the black forewing tips is white in V. cardui, pale orange in this species, and orange in the West Coast species. The latter also has a purer orange background color of the dorsal side, as opposed to the darker and (especially in V. virginiensis) redder hue of the other two.
A less reliable indicator is the row of black eyespots on the dorsal submarginal hindwing. In the American Painted Lady, those on the opposite ends of the row are often larger and have blue "pupils". In V. annabella, this applies to the inner two spots, while in V. cardui some of the black eyespots may have tiny blue pupils in the summer morph, but usually have none at all, and the eyespots themselves are all roughly the same size. The size of the wings are about 5 cm (2 in) across.

Description
Vanessa virginiensis is most easily distinguishable by its two large eyespots on the ventral side, whereas V. cardui has four small eyespots and V. annabella has none. V. virginiensis also uniquely features a white dot within the forewing subapical field, set in pink on the underside and usually also in the dorsal side's orange field.The largest spot in the black forewing tips is white in V. cardui, pale orange in this species, and orange in the West Coast species. The latter also has a purer orange background color of the dorsal side, as opposed to the darker and (especially in V. virginiensis) redder hue of the other two.
A less reliable indicator is the row of black eyespots on the dorsal submarginal hindwing. In the American Painted Lady, those on the opposite ends of the row are often larger and have blue "pupils". In V. annabella, this applies to the inner two spots, while in V. cardui some of the black eyespots may have tiny blue pupils in the summer morph, but usually have none at all, and the eyespots themselves are all roughly the same size. The size of the wings are about 5 cm (2 in) across.
