Wing span:

Identification: The wings are iridescent blue on the upperside with dark brown margins, except for the dorsal margin of the forewings which is iridescent blue. Females are duller and have broader dark brown edges. There are two tail-like projections on the hindwings. The underside of the wings is brown with two dark brown lines running vertically from the costa. Both of the lines on the forewings are not visible in males. These lines have a little bit of iridescent green on the hindwings. The hindwings also have an additional inner broken line and a postbasal spot (also with iridescent green). Males have an iridescent greenish tint on the underside of the wings.
