With luck
About 10% of wildlife watchers report a Common Flangetail sighting in Bangkok on a given day, based on 115 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 245 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.
June to September
In those months about 20% of wildlife watchers report a Common Flangetail in Bangkok on a given day, against under 5% in February and December, the lowest months. Those are among Bangkok's wettest months, with about 200 mm of rain a month against 10 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Common Flangetail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 6
Of the 6 cities where we can rate Common Flangetail sightings, Bangkok ranks 5th at about 10%. The best odds are in Yogyakarta (Indonesia, about 30%), Johor Bahru (Malaysia, about 20%) and Jakarta (Indonesia, about 10%).
Same order: Odonata
The closest relatives of the Common Flangetail that you can see in Bangkok (order Odonata, Dragonflies and Damselflies) are Ditch Jewel (about 30%), Oriental Blue Dasher (about 20%) and Common Parasol (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Flangetail is recorded against all the insects logged in Bangkok (115 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.
