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.

With luck
About 10% of wildlife watchers report a Grizzled Pintail sighting in Chennai on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 376 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Grizzled Pintail in Chennai on a given day, against under 5% in March–May and December–January, the lowest months.
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.
22nd of 33
Of the 33 cities where we can rate Grizzled Pintail sightings, Chennai ranks 22nd at about 10%. 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 Chennai (family Libellulidae, Skimmers) are Chalky Percher (about 40%), Wandering Glider (about 30%) and Slender Skimmer (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 Chennai (23 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.
