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 Cat Tien National Park on a given day, based on 36 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 125 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Chalky Percher is recorded against all the insects logged in Cat Tien National Park (36 verified sightings from 2019 to 2026), 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.
