Description : The male Common Line-blue has an upper side that varies between purplish brown and purplish with a dark tone, sometimes appearing slightly brown with a subtle purplish sheen under specific lighting. Both the forewings and hindwings display uniform coloration, featuring thin black anteciliary lines. The hindwing additionally showcases paler margins along the costa and dorsal edges. A subterminal black spot may be present in some instances within interspace 2 on the hindwing, often visible only from the underside. The tail is black with a white tip. On the underside, the wings are brown, hoary, brownish, or pale dull brown. The forewing exhibits several pairs of transverse white strigae – a subbasal pair, a shorter pair along the discocellulars, and a discal pair. These strigae are narrowly edged on the inner side of each pair with fuscous, creating the appearance of somewhat darker transverse bands against the ground color. The discal pair is irregular and dislocated at each vein, resembling a sinuous dark band. Terminal markings can be faint or well-defined, consisting of a double subterminal series of transversely linear or lunular dark spots, edged with paler shades than the ground color. There is also an anteciliary dark line. The hindwing's underside features broken and irregular transverse pairs of white strigae, similar to the forewing. These markings are more pronounced in the female, with a prominent white line edging the anteciliary black line on the inner side. The female's undersides have paler and more clearly defined markings compared to the male. Both male and female specimens often have a white terminal line before the anteciliary dark line on the undersides of the wings. The antennae, head, thorax, and abdomen are dark brown in color, with the antennae shafts speckled with white. The palpi are fringed with black, the thorax is dark greyish brown, and the abdomen is white.
