With luck
About 10% of wildlife watchers report a Forget-Me-Not sighting in Kolkata on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 158th 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 40%, if each day is a fresh chance.
March–April and December–January
In those months about 10% of wildlife watchers report a Forget-Me-Not in Kolkata on a given day, against under 5% in February and May–November, the lowest months. Those are among Kolkata's driest months, with about 25 mm of rain a month against 330 mm in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Forget-Me-Not sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
13th of 16
Of the 16 cities where we can rate Forget-Me-Not sightings, Kolkata ranks 13th at about 10%. The best odds are in Jabalpur (India, about 30%), Salem (India, about 20%) and Tuen Mun (China, about 20%).
Same family: Lycaenidae
The closest relatives of the Forget-Me-Not that you can see in Kolkata (family Lycaenidae, Gossamer-winged Butterflies) are Plains Cupid (about 30%), Pale Grass Blue (about 20%) and Gram Blue (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Forget-Me-Not is recorded against all the insects logged in Kolkata (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.
