Habitat: Sunny, open areas such as fields, lawns, gardens, levees, roadsides, and second-growth scrub. Range: Southern United States south through the West Indies and Central America to Argentina. Cannot survive harsh winters; each summer this skipper may stray and re-colonize north to northern California, southern Minnesota, southern Ontario, and southern New England.
