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.

With luck
About 10% of wildlife watchers report a Chalky Percher sighting in Brisbane on a given day, based on 231 verified sightings from GBIF citizen-science data. It is the 85th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
March and April
In those months about 20% of wildlife watchers report a Chalky Percher in Brisbane on a given day, against under 5% in July to September, the lowest months.
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.
58th of 64
Of the 64 cities where we can rate Chalky Percher sightings, Brisbane ranks 58th at about 10%. The best odds are in Hyderabad (India, about 50%), Thrissur (India, about 50%) and Chhatrapati Sambhajinagar (India, about 50%).
Same genus: Diplacodes
The closest relatives of the Chalky Percher that you can see in Brisbane (genus Diplacodes, Perchers) are Wandering Percher (about 20%) and Scarlet Percher (about 20%), 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 Brisbane (231 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.
