With luck
About 10% of wildlife watchers report an Isocentris filalis sighting in Kolkata on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 152nd 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.
February
In that month about 20% of wildlife watchers report an Isocentris filalis in Kolkata on a given day, against under 5% in April, June–July and September–December, the lowest months. That is one of Kolkata's driest months, with about 20 mm of rain against 330 mm in July.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Isocentris filalis sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 6 cities where we can rate Isocentris filalis sightings, Kolkata has the highest daily chance: about 10%. Next come Chennai (India, about 10%) and Tuen Mun (China, about 10%).

GBIF citizen-science records
It is estimated from how often the Isocentris filalis is recorded against all the insects logged in Kolkata (11 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.
