The wing colors vary with viewing angle, a phenomenon referred to as structural color. [2] In the female, the dorsal side is more camouflaged while the male presents with a vibrant blue. [11] In the male, the outer layer of the cover scales are long and narrow (250 μm × 50 μm), 2 μm apart, and parallel to the wing plane. [11]
