Wallengrenia otho, the southern broken dash, is a butterfly of the Hesperiidae family. It is found from eastern Texas and the southeastern United States, south through the West Indies and Central America to Argentina. Strays can be found as far north as central Missouri, northern Kentucky and Delaware. The wingspan is 24–35 mm. Adults are on wing from April to October in two generations (sometimes a partial third) in most of North America. In peninsular Florida and southern Texas, adults are on wing all year round.
