Claim: The Tamil lacewing,  a nymphalid butterfly which means it belongs to the largest family of butterflies,  is known by the following characteristics: its forewing has postdiscal series of black-centered, and outward turned slender white lunules, while the hindwing has broad black costal and terminal margins with black markings.
Evidence: Cethosia nietneri, the Tamil lacewing, is a species of nymphalid butterfly found in Sri Lanka and south India. The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Short streaks, followed by a series of large oval spots of the black ground colour; terminal and costal margins very broadly black, traversed by a postdiscal row of transverse short, white, inwardly-turned lunules, and a subterminal row of much more slender, outwardly-turned, similarly coloured lunules.
