Diplacodes haematodes, the scarlet percher, is a species of dragonfly in the family Libellulidae. It occurs throughout Australia (except Tasmania), Timor, New Guinea, Vanuatu, and New Caledonia. It is locally common in habitats with hot sunny exposed sites at or near rivers, streams, ponds, and lakes. It often prefers to settle on hot rocks rather than twigs or leaves, and is quite wary. This is a spectacular species of dragonfly, although small in size (wingspan 60mm, length 35mm). The male is brilliant red, the female yellow-ochre. Females have yellow infuscation suffusing the outer wings, while the males have similar colour at the bases of the wings.
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.
The species name haematodes is derived from the Greek αἱματώδης (haimatōdēs, "blood-like" or "looking like blood"), referring to the blood-red colour of the body and wing veins. Wikipedia →

Possible
About 30% of wildlife watchers report a Scarlet Percher sighting in Flinders Ranges National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 25 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 April
In those months about 40% of wildlife watchers report a Scarlet Percher in Flinders Ranges National Park on a given day, against under 5% in July–August and December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Scarlet 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.
4th of 10
Of the 10 parks where we can rate Scarlet Percher sightings, Flinders Ranges National Park ranks 4th at about 30%. The best odds are in Nitmiluk National Park (Australia, about 70%), Lamington National Park (Australia, about 40%) and Litchfield National Park (Australia, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Scarlet Percher is recorded against all the insects logged in Flinders Ranges National Park (19 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.
