In the female, the blue scales are restricted to the centre and basal part of both wings; the outer margins are marked by a wide black band.
Male. Upperside dark purple-blue, shining in certain lights, coloured somewhat like Arhopala centaurus pirithous, but brighter blue, costal and outer marginal line black. Cilia black, tails black, a rather long tail at the end of vein 2, slight projections at the ends of all the other veins of the hindwing, more pronounced at the ends of veins 1 and 3 than at the ends of the others. Underside grey suffused with pinkish-brown, the lower portion of forewing pale, the hindwing darker than the forewing, but varying much in shade of colour, spots and bands chocolate-brown. Forewing with a small spot in the cell near the base, a larger one in the middle, four conjoined spots at the end, the third from the upper end minute and sometimes absent, a discal band of...

Rare
Under 5% of wildlife watchers report a Large Oakblue sighting in Kochi on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 277th most-seen of the 428 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and November–February
In those months about 10% of wildlife watchers report a Large Oakblue in Kochi on a given day, against under 5% in March and May–October, the lowest months. Those are among Kochi's driest months, with about 75 mm of rain a month against 490 mm in June.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Large Oakblue sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 5
Of the 5 cities where we can rate Large Oakblue sightings, Kochi ranks 3rd at under 5%. The best odds are in Dehradun (India, about 10%) and Bengaluru (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Large Oakblue is recorded against all the insects logged in Kochi (9 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.
