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.

Rare
Under 5% of wildlife watchers report a Grizzled Pintail sighting in Bengaluru on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 268th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Grizzled Pintail in Bengaluru on a given day, against under 5% in October to June, the lowest months. Those are among Bengaluru's wettest months, with about 120 mm of rain a month against almost none 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.
32nd of 33
Of the 33 cities where we can rate Grizzled Pintail sightings, Bengaluru ranks 32nd at under 5%. The best odds are in Salem (India, about 30%), Dhaka (Bangladesh, about 30%) and Kota (India, about 20%).
Same family: Libellulidae
The closest relatives of the Grizzled Pintail that you can see in Bengaluru (family Libellulidae, Skimmers) are Chalky Percher (about 30%), Wandering Glider (about 30%) and Ditch Jewel (about 20%), 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 Bengaluru (12 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.
