Five-bar Swordtail Graphium antiphates is a species
Species
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

Butterfly
A butterfly is a mainly day-flying insect of the order Lepidoptera, which includes the butterflies and moths. Like other holometabolous insects, the butterfly's life cycle consists of four parts: egg, larva, pupa and adult. Most species are diurnal. Butterflies have large, often brightly coloured...

 for terms used

The ground colour of the upperside of both males and females is white. The forewing has the cell crossed by five short black bands, of which the basal extends to the dorsum
Dorsum
Dorsum is a Latin word. In science, it could mean:* Dorsum , the posterior side of an animal* Dorsum , a term used in astrogeology for a ridge* Theta Capricorni, a star on the back of the Goat...

, the sub-basal into interspace 1, the medial and pre-apical up to the median vein, and the apical or fifth along the discocellulars; this last band extends broadly on both sides of the veinlets and terminates at the lower apex of the cell; beyond these are broad postdiscal and terminal black transverse bands from costa to tornal angle; the two bands coalesce below vein 4 and terminate in a point at the tornus; the white portions of the cell anteriorly overlaid with pale green; short broken glossy green bands between the black cellular apical band and the discal band and anteriorly between the latter and the terminal band.

The upperside of the hind wing has the basal three-fourths uniformly white, with black markings on the underside that show through; the terminal fourth dark grey traversed by a curved irregular subterminal series of black crescent shaped marks that ends in a black tornal spot and a terminal black band that follows the indentations of the wing; the emargination below the black tornal spot edged with ochraceous; the tail blackish-grey, edged and tipped with white.

The underside of the fore wing is similar to the upperside in markings but the green shading over the white portions in the basal half of the cell more decided; the discal and terminal transverse black bands are separate, and are not joined posteriorly, the former edged posteriorly on both sides by dark grey due to the black on the upperside that shows through by transparency. The underside of the hind wing is half green on the basal part while the outer half white; a large black tornal spot; a black line along the dorsum that curves above the tornal spot outwards to vein 2; a straight subbasal black band from costa across cell that terminates on vein 2, where it joins the dorsal black line; a broader black band from costa across apex of cell extended into base of interspace 3; an irregular discal series of black markings curved inwards posteriorly towards the tornal spot; a subterminal series of very small slender black lunules in pairs, the ground-colour on the inner side of these darkened to rich ochreous-yellow; lastly, a series of short terminal black bars in the interspaces so arranged as to follow indentations of the termen; tail dusky black edged with white. Antenna black; head and thorax anteriorly with a broad black medial band, rest of thorax bluish; abdomen white, marked beneath on each side by a black stripe.

Race alcibiades, Fabr. is the most widely spread race of antiphates, from which it differs as follows:—
Upperside of males and females, all the black markings shorter and narrower. Fore wing: the discal and terminal bands separate, the former rarely extended below vein 3, the latter in no specimen reaches the dorsal margin. Hind wing: the broad grey area on the terminal margin reduced to a small patch of grey at the apices of interspaces 2 to 4; the subterminal black markings rarely present anteriorly, generally confined to the limits of the grey patch. Underside: the extent of the black markings similarly reduced, otherwise as in the typical form.

The width and length of the transverse black markings on the upperside of the fore wing, also the extent of the grey terminal area and the presence or absence of the black subterminal markings on the upperside of the hind wing, are all very variable.
Form nebulosus, Butler, is a melanistic variety recorded from Sikkim.

Var. continentalis, Eimer, has the caudal area of the hind wing on the upperside suffused with black.

Var. itamputi, Butler, has the postdiscal and terminal black bands on the upperside of the forewing united posteriorly, but neither band extends up to the tornus.

Var. ceylanicus, Eimer,has the basal two bands on the upper-side of the fore wing extended beyond the median vein, the preapical cellular band not triangular and extended to the median vein.

Life history

The caterpillar is white in the early stage and turns yellow in the last instar. In its late stage not unlike the caterpillar of Pathysa nomius. (Davidson & Aitken quoted in Bingham)
The green pupa is as in all swallowtails held by a silk girdle. Said to be found mainly on the plant Unona lawii and never under stones. (Davidson and Aitken)
