Crassus swallowtail

Wing span:

Identification: The wings are dark brown on the upperside, with a dark blue tint (faint in males) and a white costal band (small white apical patch present in females instead of this band) on the hindwings. Females have a white band (with dark brown veins) on the forewings, radiating from the base to the outer postdiscal region. This band is faintly present on the upperside of the forewings in males, but very visible on the underside. Both males and females are otherwise brown on the underside, and have black-bordered red submarginal lunules on the underside of the hindwings.
