With luck
About 10% of wildlife watchers report a Large Oakblue sighting in Bengaluru on a given day, based on 46 verified sightings from GBIF citizen-science data. It is the 115th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
February
In that month about 20% of wildlife watchers report a Large Oakblue in Bengaluru on a given day, against under 5% in June and December, the lowest months. That is one of Bengaluru's driest months, with about 5 mm of rain against 150 mm in September.
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.
Among the best
Of the 5 cities where we can rate Large Oakblue sightings, Bengaluru ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Dehradun (India, about 10%).
Same family: Lycaenidae
The closest relatives of the Large Oakblue that you can see in Bengaluru (family Lycaenidae, Gossamer-winged Butterflies) are Red Pierrot (about 30%), Plains Cupid (about 30%) and Common Cerulean (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Large Oakblue is recorded against all the insects logged in Bengaluru (46 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.
