Diplacodes trivialis is a species of dragonfly in the family Libellulidae known as the chalky percher or ground skimmer. It is found in Seychelles, Oman, United Arab Emirates, China, Japan, India, Maldives and southwards to New Guinea and Australia.
Diplacodes trivialis is small dragonfly with bluish eyes and greenish-yellow or olivaceous thorax and abdomen with black marks. In very old adults, the whole thorax and abdomen become uniform pruinosed blue. Clear wings, without apical or basal markings, and the creamy white anal appendages and deep pruinescence in adults help to distinguish this species from others in its genus. It breeds in ponds, wet rice fields, shallow lakes, drainage ditches and similar habitats. It is one of the most common dragonflies in Asia, found in both the plains and hills and in dry and wet areas.
The genus name Diplacodes combines Diplax, a genus name derived from the Greek δίς (dis, "twice") and πλάξ (plax, "flat and broad"), with the Greek suffix –ώδης (-ōdēs, "resembling" or "having the nature of"). The name refers to the similarity of the genus to Diplax and Diplacina.

Possible
About 30% of wildlife watchers report a Chalky Percher sighting in Thiruvananthapuram on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 20th most-seen of the 112 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.
February and March
In those months about 50% of wildlife watchers report a Chalky Percher in Thiruvananthapuram on a given day, against under 5% in July to December, the lowest months. Those are among Thiruvananthapuram's driest months, with about 35 mm of rain a month against 290 mm in October.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Chalky Percher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
32nd of 64
Of the 64 cities where we can rate Chalky Percher sightings, Thiruvananthapuram ranks 32nd at about 30%. The best odds are in Hyderabad (India, about 50%), Thrissur (India, about 50%) and Chhatrapati Sambhajinagar (India, about 50%).
Same family: Libellulidae
The closest relatives of the Chalky Percher that you can see in Thiruvananthapuram (family Libellulidae, Skimmers) are Slender Blue Skimmer (about 40%), Ditch Jewel (about 30%) and Common Picture Wing (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chalky Percher is recorded against all the insects logged in Thiruvananthapuram (22 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.
