Females are dimorphic. The yellow morph differs from the male in having a blue postmedian area on the dorsal hindwing. In the dark morph, the areas that are normally yellow are replaced with dark gray or black. The bluish postmedian area on the ventral hindwing has one row of orange spots. A shadow of the "tiger stripes" can be seen on the underside of some dark females.
Spotted in a tree in a neighborhood in Conway, Arkansas. Lots of deciduous trees nearby.
