Likely
About 40% of wildlife watchers report a Scarlet Skimmer sighting in Dhaka on a given day, based on 44 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 92 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 50% of wildlife watchers report a Scarlet Skimmer in Dhaka on a given day, against under 5% in December to February, the lowest months. That is one of Dhaka's wettest months, with about 280 mm of rain against 10 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Scarlet Skimmer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 79
Of the 79 cities where we can rate Scarlet Skimmer sightings, Dhaka ranks 12th at about 40%. The best odds are in Kota (India, about 70%), Vasai-Virar (India, about 40%) and Kolkata (India, about 40%).
Same family: Libellulidae
The closest relatives of the Scarlet Skimmer that you can see in Dhaka (family Libellulidae, Skimmers) are Pied Paddy Skimmer (about 40%), Oriental Blue Dasher (about 30%) and Slender Skimmer (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Scarlet Skimmer is recorded against all the insects logged in Dhaka (44 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.
