Southern Broken-Dash (Wallengrenia otho)
This species is often confused with the northern broken-dash in the field.  Field guides always point out the backwards 3 on the underside of the forewing on both species.  The northern broken-dash is usually browner than the southern, but because of variations in color of individuals, this doesn't always help.  To distinguish the two species, check the fringes.  The fringes on the forewing and hindwing of southern broken-dash are different colors.  The hindwing fringe color is orange while the forewing color is darker.  See the photo below.
