Jamides celeno, the common cerulean, is a small butterfly found in Indomalayan realm belonging to the lycaenids or blues family. The species was first described by Pieter Cramer in 1775. Like many tropical butterflies, this species shows seasonal polyphenism, with the appearance differing between adults according to the season.
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 anteciliary 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 (paired) 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 forewing is much reduced and the subterminal series of black spots in the hindwing is altogether missing.

With luck
About 10% of wildlife watchers report a Common Cerulean sighting in Kuala Lumpur on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 116th most-seen of the 323 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May–July, September and December–March
In those months about 10% of wildlife watchers report a Common Cerulean in Kuala Lumpur on a given day, against under 5% in April, August and October–November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Cerulean sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
25th of 27
Of the 27 cities where we can rate Common Cerulean sightings, Kuala Lumpur ranks 25th at about 10%. The best odds are in Salem (India, about 40%), Jabalpur (India, about 30%) and Thiruvananthapuram (India, about 30%).
Same family: Lycaenidae
The closest relatives of the Common Cerulean that you can see in Kuala Lumpur (family Lycaenidae, Gossamer-winged Butterflies) are Lesser Grass Blue (about 20%), Common Imperial (about 10%) and Plains Cupid (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Cerulean is recorded against all the insects logged in Kuala Lumpur (15 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
