In 3 days ~30% in a week ~60%
Pseudagrion cingillum is a species of damselfly in the family Coenagrionidae, commonly known as a northern riverdamsel. It is a medium-sized, blue and black damselfly. It is found in northern Australia and New Guinea, where it inhabits streams, pools and ponds.
The genus name Pseudagrion is derived from the Greek ψευδής (pseudēs, "false" or "not true"), combined with Agrion, a genus name derived from the Greek ἄγριος (agrios, "wild"). Agrion was the name given in 1775 by Johan Christian Fabricius for all damselflies.
The species name cingillum is the diminutive of the Latin cingulum ("girdle"), meaning "small girdle", likely referring to the narrow abdominal rings. List of Odonata species of Australia Wikipedia →

With luck
About 10% of wildlife watchers report a Northern Riverdamsel sighting in Kakadu National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 57th 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 60%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Northern Riverdamsel in Kakadu National Park on a given day, against under 5% in April, August–October and December–February, the lowest months. That is one of Kakadu National Park's wettest months, with about 170 mm of rain against almost none in August.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Northern Riverdamsel 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 Northern Riverdamsel sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Coenagrionidae
The closest relatives of the Northern Riverdamsel that you can see in Kakadu National Park (family Coenagrionidae, Narrow-winged Damselflies) are Australian Bluetail (about 20%), Redtail (about 10%) and Colourful Bluetail (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Northern Riverdamsel is recorded against all the insects logged in Kakadu National Park (7 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.
