Comments: Extremely variable regionally. In most of eastern North America this is primarily a pest of solanaceous crops, especially tomato and tobacco, of farms and gardens, although in New Jersey larvae also occur and mature (Dale Schweitzer) on introduced nightshades (Solanum) and Datura which is possibly native. It seem unlikely the species could occur in most of the east based only on wild plants. Going southwest, this moth is clearly part of the native fauna of the greater Sonoran desert region where it has several native foodplants, mostly, but not entirely Solanaceae (Tuttle, 2009), breeding mainly in riparian areas during the summer rainy season. Eastern North American populations do not appear to be commonly migratory (discussed by Schweitzer, 2006). South of the USA, habitats apparently include a variety of tropical scrub, forest, and woodlands, as well as agricultural lands.
