Rare
Under 5% of wildlife watchers report an Orange-Tailed Marsh Dart sighting in New Delhi on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 139th most-seen of the 174 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–April, June and October
In those months about 10% of wildlife watchers report an Orange-Tailed Marsh Dart in New Delhi on a given day, against under 5% in May, July–September and November–February, the lowest months. Those are among New Delhi's driest months, with about 30 mm of rain a month against 220 mm in July.
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.
15th of 15
Of the 15 cities where we can rate Orange-Tailed Marsh Dart sightings, New Delhi ranks 15th at under 5%. The best odds are in Thrissur (India, about 30%), Kolkata (India, about 30%) and Kuching (Malaysia, 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 New Delhi (6 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.
