Southern broken dash

''Wallengrenia otho'', the southern broken dash or broken dash skipper, is a butterfly of the family Hesperiidae. It was originally described by Smith in 1797. 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 in most of North America. In peninsular Florida and southern Texas, adults are on wing all year round.

The larvae feed on ''Paspalum'' species and ''Stenotaphrum secundatum''. Adults feed on the nectar from flowers including pickerelweed, selfheal and sweet pepperbush.
