American Lady (Vanessa virginiensis [Drury])
Wing span: 1 3/4 - 2 5/8 inches (4.5 - 6.7 cm).
Identification: Upperside with uneven brown, yellow, and orange pattern. Forewing with a black apical patch, a small white spot in the orange field below the patch, and a white bar at the leading edge of the forewing. Underside of hindwing with two large eyespots. Winter form is smaller and paler, summer form larger with brighter coloring.
Life history: During the afternoon, males perch on hilltops or on low vegetation if there are no hills. Females lay eggs singly on the top of host plant leaves. Caterpillars are solitary, living and feeding in a nest of leaves tied with silk. Adults hibernate.
Flight: Three to four broods from May-November, all year in the Deep South and South Texas. It is not known if adults can survive very cold winters; the East may have to be recolonized each year by southern migrants.
Caterpillar hosts: Plants in the sunflower family: sweet everlasting (Gnaphalium obtusifolium), pearly everlasting (Anaphalis margaritacea), plantain-leaved pussy toes (Antennaria plantaginifolia), wormwood (Artemisia), ironweed (Vernonia), and burdock (Arctium).
Adult food: Flower nectar almost exclusively, including dogbane, aster, goldenrod, marigold, selfheal, common milkweed, and vetch.
Habitat: Open places with low vegetation including dunes, meadows, parks, vacant lots, forest edges.
Range: Resident in the southern United States, Mexico, and Central America south to Colombia. Migrates to and temporarily colonizes the northern United States, southern Canada, the West Indies, and Europe. Rare stray to Newfoundland and Labrador.
Conservation: Not required.
The Nature Conservancy Global Rank: G5 - Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.
Management needs: None reported.
