Common Cerulean

Jamides celeno

The Common Cerulean (Jamides celeno) is a small butterfly found in India belonging to the Lycaenids or Blues family

Description

Like many tropical butterflies, this species shows seasonal polyphenism, with the appearance differing between adults according to the season.

Dry-season brood

Male upperside has the ground colour pale bluish white. The forewing has the terminal margin narrowly edged with black that broadens very slightly towards the apex of the wing; the cilia are brownish black.

The hindwing is uniformly coloured, except for an anticiliary black line faintly edged on the inner side by a white line within which and touching it is a row of black spots, the anterior spots very faint, the spot in interspace 2 large and well-defined, two geminate spots in interspace 1 and a very small black lunular dot in interspace 1a; cilia brown, white at the base in the interspaces. In specimens obtained in the height of the dry season the black edging to the termen of the fore wing is much reduced and the subterminal series of black spots in the hind wing is altogether missing

Wet-season brood

Closely resembles the males and females of the dry-season brood; the markings are similar but the ground-colour is generally darker both on the upper and undersides, while the black edging to the fore wing and the black postdiscal and terminal markings to the hind wing on the upperside are broader and more clearly defined. Antennae, head, thorax and abdomen as in the dry-season brood

Larva

“When full-fed just half an inch in length, of a dull reddish-green colour, thickly shagreened with minute white tubercles, scarcely, if at all, hairy; the head pale ochraceous, entirely hidden beneath the second segment; the segments increasing in width to about the fifth, the two anal segments slightly decreasing and above flattened, especially the thirteenth; the erectile organs very small; a dorsal pulsating line, somewhat darker than the rest of the body; a subdorsal series of pale green oblique streaks, one on each segment on each side from the third to the eleventh segment inclusive; no other conspicuous markings. Dr. Forel has identified the ant that attends the larva in Calcutta, as Camponotus mitis, Smith. Dr. G. King identifies the plant on which the larva feeds in Calcutta as Heynea trijuga, Roxburgh.”

Pupa

Of the usual Lycaenid shape, quite smooth, neither hairy nor pitted, pale ochreous greenish, the upper portions of the abdominal segments darker, covered throughout with coarse, rounded, blackish spots placed irregularly; a dorsal and a subdorsal series of similar but larger spots or blotches placed regularly. Head bluntly rounded, thorax slightly humped and constricted posteriorly, end of the abdomen rounded
