Possible
About 30% of wildlife watchers report an Orange-Tailed Marsh Dart sighting in Kolkata on a given day, based on 121 verified sightings from GBIF citizen-science data. It is the 11th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
June
In that month about 50% of wildlife watchers report an Orange-Tailed Marsh Dart in Kolkata on a given day, against under 5% in December and January, the lowest months. That is one of Kolkata's wettest months, with about 230 mm of rain against 10 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Orange-Tailed Marsh Dart sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 15 cities where we can rate Orange-Tailed Marsh Dart sightings, Kolkata ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Thrissur (India, about 30%).
GBIF citizen-science records
It is estimated from how often the Orange-Tailed Marsh Dart is recorded against all the insects logged in Kolkata (121 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.
