The Ciliate Blue is a small butterfly
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...

 family.

Male

Upperside: dull purple; bases of the wings suffused with blue ; both fore and hind wings with well-marked jet-black anticiliary lines, that on the fore wing expand slightly at tho apex. Hind wing: the costal margin above vein 7 and the dorsal margin below vein 1a fuscous brown; irregular, transverse, sub-terminal black spots in interspaces 1 to 3, those in interspaces 1 and 2 much larger than that in interspace 3; posterior basal area covered with long purplish-brown hairs. Cilia of both fore and hind wings brown.

Underside: purplish brown with a smooth satiny lustre. Forewing: a short band on the discocellulars, a transverse comparatively broad discal band with very sinuate margins, and a subterminal, continuous, lunular, much narrower band; the former two brown, of a shade darker than the groundcolour, the subterminal band fuscous black; the band on the discocellulars and the discal band edged narrowly with white both on the inner and outer sides, the subterminal band very obscurely similarly edged on the outer side only. Hind wing: somewhat densely irrorated with black scales at extreme base and crossed transversely by seven or eight very irregular lines of slender white lunules; the outer two lines outwardly concave, the others outwardly convex, each lunule of the inner line of the former two series touching the corresponding lunule of the line next to it on the inner side, so that in each interspace the two touching lines of lunules seem to form a series of markings like X; finally, a white-edged black spot in tho middle of the dorsum and another subterminal black spot crowned inwardly with orange in interspace 3. Both fore and hind wings with slender jet-black anticiliary lines and brown cilia, the anticiliary line on the hind wing edged inwardly and outwardly by a white thread.

Antennae black, the shafts speckled with white; head,thorax and abdomen purplish brown.

Female

Upperside : brown, the bases of the wings glossed with pale violet-blue on the fore wing, in some specimens extended for two-thirds the length of the wing but always more or less of a broad margin of the ground-colour is left along the costa, a still broader margin along the term en and a narrow edging along the dorsum ; on the hind wing the blue gloss rarely extends further than the basal third. Both fore and hind wings with slender anticiliary black lines, that on the hind wing posteriorly is inwardly margined with a thread of white, on the inner side of which again and touching it are three or four conical or triangular small black spots in the interspaces. Cilia of both wings pale brown.

Underside: ground-colour slightly paler, markings similar.

Antennae blackish brown, the shafts speckled with white as in the male ; head, thorax and abdomen brown; beneath: the palpi, thorax and abdomen paler brown.

Larva

"When full-fed .62 of an inch in length, somewhat dark green in colour (of a darker shade than most Lycaenid larvae), smooth and shining, the whole surface covered with minute pits to be seen only under a strong magnifying-glass. The head is very small and retractile as usual and of a pale green colour; the second segment is unmarked, the third to sixth segments inclusive have some obscure reddish-brown dorsal blotches, the three following segments are unmarked, the tenth to twelfth segments have somewhat similar blotches to those on the third to the sixth segments, but they are more distinct and darker in shade. There is a pale yellow lateral line just above the legs. All the segments are irregularly and broadly pitted at the sides; these pits seem to assume more or less the form of a longitudinal subdorsal depression, below which to the lateral line the colour of the insect is slightly paler. The whole larva is much depressed, somewhat wider than high and seems to gradually increase in breadth to the tenth segment, the last segment is almost as broad and rounded. The larva varies greatly in colour and markings, some being pale green throughout and unmarked, others again are reddish brown throughout. It feeds in Calcutta on Nephelium litchi, Cassia fistula, and Heynea trijuga, and not improbably, as it feeds on so many bushes, it will eat others. Dr. Forel identifies the ant which attends the larva as Oecophylla smaragdina
Oecophylla smaragdina
Oecophylla smaragdina is a species of arboreal ant found in Asia and Australia. They make nests in trees made of leaves stitched together using the silk produced by their larvae.Weaver ants may be red or green...

Pupa

".4 of an inch in length, of the usual Lyccenid shape, the tail pointed, the thorax slightly humped and ending in a somewhat sharp ridge line on the back; it is coloured pale ochraceous and bears a prominent diamond-shaped mark posteriorly, It is smooth throughout, reddish brown sprinkled with minute darker dots." (de Niceville.)
