Acisoma panorpoides, the Asian pintail, trumpet tail, or grizzled pintail, is a species of dragonfly in the family Libellulidae. It is widespread in Asia, from the Indian subcontinent to Japan, the Philippines and Indonesia.
It is a small dragonfly with blue eyes. Its thorax is azure-blue marbled with black to form a beautiful pattern on the dorsum and the sides. Abdomen is azure-blue, marked with black. Segments 1 to 5 have sutures finely and ventral borders more broadly black. There is a dorsal stripe which broadens at the jugal sutures and apical borders of segments. There is a speckled stripe on sub-dorsum of segments 1 to 4. There is a large ventro-lateral spot on each of segments 3 to 5. Segments 6 and 7 are black with a large spot of blue on each side. Segments 8 to 10 are entirely black. Anal appendages are bluish-white. Female is similar to the male; but with greenish-yellow eyes, thorax and abdominal segments up to 5.
The characteristic shape of the abdomen will serve to distinguish this species from other Libellulidae. It is found in subtropical or tropical swampy or marshy habitats. It has a very weak and short flight and... Wikipedia →

Possible
About 30% of wildlife watchers report a Grizzled Pintail sighting in Dhaka on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 28th most-seen of the 92 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June–July and November
In those months about 40% of wildlife watchers report a Grizzled Pintail in Dhaka on a given day, against under 5% in January–February and April–May, 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 pm
Across all the parks we cover, that three-hour window holds the most Grizzled Pintail sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 33 cities where we can rate Grizzled Pintail sightings, Dhaka ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Salem (India, about 30%).
Same family: Libellulidae
The closest relatives of the Grizzled Pintail 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 Grizzled Pintail is recorded against all the insects logged in Dhaka (20 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.
