With luck
About 10% of wildlife watchers report a Falcate Oak Blue sighting in Kolkata on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 172nd most-seen of the 213 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April and September–December

Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Falcate Oak Blue sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 5 cities where we can rate Falcate Oak Blue sightings, Kolkata ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Fuzhou (China, about 10%) and Tuen Mun (China, about 10%).
Same family: Lycaenidae

GBIF citizen-science records
It is estimated from how often the Falcate Oak Blue is recorded against all the insects logged in Kolkata (8 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.
