Possible
About 20% of wildlife watchers report a Scarlet Adjutant sighting in Dhaka on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 45th 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 a Scarlet Adjutant in Dhaka on a given day, against under 5% in November to March, the lowest months. Those are among Dhaka's wettest months, with about 290 mm of rain a month against 10 mm in January.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Scarlet Adjutant sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
4th of 13
Of the 13 cities where we can rate Scarlet Adjutant sightings, Dhaka ranks 4th at about 20%. The best odds are in Thiruvananthapuram (India, about 30%), Thrissur (India, about 20%) and Kochi (India, about 20%).
Same family: Libellulidae
The closest relatives of the Scarlet Adjutant that you can see in Dhaka (family Libellulidae, Skimmers) are Pied Paddy Skimmer (about 40%), Scarlet Skimmer (about 40%) and Oriental Blue Dasher (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Scarlet Adjutant is recorded against all the insects logged in Dhaka (11 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.
