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 Minneriya National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 33rd most-seen of the 44 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Common Cerulean in Minneriya National Park on a given day, against under 5% in June and August–April, 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.
5th of 5
Of the 5 parks where we can rate Common Cerulean sightings, Minneriya National Park ranks 5th at about 10%. The best odds are in Periyar National Park (India, about 30%), Sinharaja Forest Reserve (Sri Lanka, about 30%) and Tangkoko Nature Reserve (Indonesia, about 20%).
Same family: Lycaenidae
The closest relatives of the Common Cerulean that you can see in Minneriya National Park (family Lycaenidae, Gossamer-winged Butterflies) are Lesser Grass Blue (about 10%) and Common Pierrot (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 Minneriya National Park (5 verified sightings from 2019 to 2026), 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.
