With luck
About 10% of wildlife watchers report an Indian Common Clubtail sighting in Kolkata on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 72nd most-seen of the 213 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report an Indian Common Clubtail in Kolkata on a given day, against under 5% in January and February, the lowest months. That is one of Kolkata's driest months, with about 50 mm of rain against 330 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Indian Common Clubtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 16
Of the 16 cities where we can rate Indian Common Clubtail sightings, Kolkata ranks 7th at about 10%. The best odds are in Salem (India, about 20%), Bhopal (India, about 20%) and Thiruvananthapuram (India, about 20%).
Same order: Odonata
The closest relatives of the Indian Common Clubtail that you can see in Kolkata (order Odonata, Dragonflies and Damselflies) are Scarlet Skimmer (about 40%), Ditch Jewel (about 40%) and Coromandel Marsh Dart (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Indian Common Clubtail is recorded against all the insects logged in Kolkata (36 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.
