Nannodiplax rubra
In 3 days ~20% in a week ~40%
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 →

With luck
About 10% of wildlife watchers report a Pygmy Percher sighting in Brisbane on a given day, based on 103 verified sightings from GBIF citizen-science data. It is the 197th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
September–October and December–May
In those months about 10% of wildlife watchers report a Pygmy Percher in Brisbane on a given day, against under 5% in June–August and November, the lowest months.
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.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Pygmy Percher sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Libellulidae
The closest relatives of the Pygmy Percher that you can see in Brisbane (family Libellulidae, Skimmers) are Wandering Percher (about 20%), Fiery Skimmer (about 20%) and Blue Skimmer (about 20%), 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 Brisbane (103 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.
