With luck
About 10% of wildlife watchers report an Indian Common Clubtail sighting in Dhaka on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 59th most-seen of the 92 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May and September
In those months about 30% of wildlife watchers report an Indian Common Clubtail in Dhaka on a given day, against under 5% in June and October–April, the lowest months. Those are among Dhaka's wettest months, with about 290 mm of rain a month against 10 mm in January.
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.
6th of 16
Of the 16 cities where we can rate Indian Common Clubtail sightings, Dhaka ranks 6th 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 Dhaka (order Odonata, Dragonflies and Damselflies) are Pied Paddy Skimmer (about 40%), Scarlet Skimmer (about 40%) and Coromandel Marsh Dart (about 30%), 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 Dhaka (7 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.
