Habitat: Open, dry places including coastal flats, weedy fields, grasslands, road edges, meadows, and hillsides.
Range: Resident in Guatemala north to peninsular Florida and the Southwest. Cannot survive cold winters, therefore every summer re-colonizes through the Great Plains to southeast Washington, southeast Idaho, Wyoming, and Minnesota.
