Nososticta koongarra is a species of Australian damselfly in the family Platycnemididae, commonly known as a citrine threadtail. It has only been found on the Arnhem Land escarpment in Northern Territory, where it inhabits streams.
Nososticta koongarra is a small, slender damselfly; males are coloured black with bright blue markings and yellow tinted wings, females are black with yellowish-white markings and clear wings. The genus name Nososticta combines the Greek νόσος (nosos, "disease") with στικτός (stiktos, "spotted" or "marked"). The suffix -sticta is commonly used in names of taxa related to Protoneura and the subfamily Isostictinae.
The species name koongarra is named for Koongarra in the Northern Territory, where the original specimens of this species were collected. List of Odonata species of Australia Wikipedia →

With luck
About 10% of wildlife watchers report a Citrine Threadtail sighting in Kakadu National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 76 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Citrine Threadtail in Kakadu National Park on a given day, against under 5% in May to March, the lowest months. That is one of Kakadu National Park's driest months, with about 50 mm of rain against 350 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Citrine Threadtail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Kakadu National Park, in our data
Kakadu National Park is the only park on Wallace's Line with enough records to rate Citrine Threadtail sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Odonata
The closest relatives of the Citrine Threadtail that you can see in Kakadu National Park (order Odonata, Dragonflies and Damselflies) 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 Citrine Threadtail is recorded against all the insects logged in Kakadu National Park (10 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.
