About Graphium cloanthus Westwood, 1841
Graphium cloanthus Westwood, 1841 has the following morphological features. Upperside forewing: The costal margin up to a line running through the anterior half of the cell to the wing apex, and the terminal margin are broadly black. The medial portion of the wing is pale hyaline, glass-like, greenish yellow. This pale area is interrupted anteriorly by irregular black bands that connect the black on the costa to the black on the termen: one band crosses the middle of the cell and runs along vein 4, another sits at the apex of the cell and runs along vein 5, and two shorter, more oblique bands lie closer to the wing apex. The hyaline spot left close to the apex is much smaller than the spots below it. Finally, there is a pale, somewhat obscure broad subterminal line. Upperside hindwing: An even black band along the dorsum continues from the black on the forewing's costal margin, and joins below to a very broad black band on the terminal margin. The remaining triangular medial portion of the wing, and a transverse subterminal series of large spots, are hyaline greenish-yellow. The dorsal margin of the wing has long soft pale hairs, and the tornal area has touches of grey scaling. Underside: The pattern is similar to the upperside. On the hindwing, there is a series of slender crimson markings at the extreme base of the wing along vein 1; these markings broaden at the tornal angle and in interspaces 2 to 5. Finally, there are slender admarginal white lines at the tornal angle and in interspaces 2 and 3. Antennae, head, thorax, and abdomen are dark brownish black. The thorax has lateral dark grey pubescence. On the underside, the palpi, thorax, and abdomen have touches of dingy white, and the abdomen has three lateral whitish stripes. In males, the inner abdominal fold is grey, and is studded with a brush of long white hairs, as seen in Graphium sarpedon.
