North American Ecology (US and Canada)Agraulis vanillae is a year-round resident in a few small regions of the United States, including Calif., southern Tex. and southern Fla. It is migratory throughout much of the US (Scott 1986), and ranges south to Argentina, and the Antilles and Bahamas. Habitats are forest margins, fields, scrub, suburbs. Host plants are usually vines, and include many species restricted to one genus Passiflora (Passifloraceae). Eggs are laid on the host plant singly. There are multiple flights, year round in s. Tex., s. Fla, and s. Calif (Scott 1986). Considered synonymous with Dione vanillae by some sources (Scott 1986).
