Nannodiplax rubra, commonly called the pygmy percher, is a species of dragonfly in the monotypic genus Nannodiplax. Its distribution seems to be limited to Australia and New Guinea. They are tiny dragonflies (wingspan 40 mm, length 25 mm) with a bright red abdomen and clear wings. They are found near a wide variety of rivers and streams. The Australian distribution ranges from Broome, Western Australia via the north and east to around Coffs Harbour, New South Wales. The taxon has not yet been assessed for the IUCN Red List, but it is listed in the Catalogue of Life.
The genus name Nannodiplax combines the Greek νάννος (nannos, "dwarf") with Diplax, a genus name derived from the Greek δίς (dis, "twice") and πλάξ (plax, "flat and broad"). The name probably refers to the small size of members of the genus.
The species name rubra is derived from the Latin ruber ("red"), referring to the colour of the abdomen. List of Odonata species of Australia Wikipedia →

Possible
About 30% of wildlife watchers report a Pygmy Percher sighting in Kakadu National Park on a given day, based on 41 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 76 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.
April
In that month about 50% of wildlife watchers report a Pygmy Percher in Kakadu National Park on a given day, against under 5% in February, the lowest month. That is one of Kakadu National Park's driest months, with about 50 mm of rain against 350 mm in January.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Pygmy 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.
2nd of 4
Of the 4 parks where we can rate Pygmy Percher sightings, Kakadu National Park ranks 2nd at about 30%. The best odds are in Litchfield National Park (Australia, about 40%).
Same family: Libellulidae
The closest relatives of the Pygmy Percher that you can see in Kakadu National Park (family Libellulidae, Skimmers) are Painted Grasshawk (about 40%), Graphic Flutterer (about 40%) and Common Glider (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pygmy Percher is recorded against all the insects logged in Kakadu National Park (41 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.
