With luck
About 10% of wildlife watchers report a Crotalaria Pod Borer sighting in Kolkata on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 124th 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 50%, if each day is a fresh chance.
April and July
In those months about 20% of wildlife watchers report a Crotalaria Pod Borer in Kolkata on a given day, against under 5% in May, September–October and December–March, the lowest months. Those are among Kolkata's wettest months, with about 190 mm of rain a month against 10 mm in December.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Crotalaria Pod Borer sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 5 cities where we can rate Crotalaria Pod Borer sightings, Kolkata has the highest daily chance: about 10%. Next come Pune (India, under 5%) and Mumbai (India, under 5%).
Same family: Erebidae
The closest relatives of the Crotalaria Pod Borer that you can see in Kolkata (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Seven-Spotted Handmaiden Moth (about 30%), Tropical Tiger Moth (about 20%) and Banyan Tussock Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Crotalaria Pod Borer is recorded against all the insects logged in Kolkata (13 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.
