In the case of degandii the male has the outer area of the wings is a shimmering and highly reflective blue, while in the female the outer wings are steely green. The underside hindwings of all Asterope species are grey, overlaid to a greater or lesser extent with a metallic greenish or bluish hue, and marked with a very distinctive pattern of black spots. In some species including degandii the basal area of the underside wings are bright orange.
