In 3 days ~40% in a week ~70%
Notolibellula bicolor is a species of dragonfly in the family Libellulidae, known as the bicoloured skimmer. It is the only known species of Notolibellula. It is found across northern Australia where it inhabits rock-holes and still waters.
It is a medium-sized dragonfly with the male having a bluish thorax and a red end to his abdomen. The genus name Notolibellula combines the Greek νότος (notos, "south wind", hence "southern") with Libellula, a predominantly European genus. The name refers to the southern or Australian distribution of the genus.
The species name bicolor is Latin for "two-coloured" or "of two colours", referring to the vivid red and blue colouration. List of Odonata species of Australia Wikipedia →

Possible
About 20% of wildlife watchers report a Bicoloured Skimmer sighting in Litchfield National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 43 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Bicoloured Skimmer in Litchfield National Park on a given day, against under 5% in May–June and August–February, the lowest months. That is one of Litchfield National Park's driest months, with about 50 mm of rain against 400 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Bicoloured Skimmer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Litchfield National Park, in our data
Litchfield National Park is the only park on Wallace's Line with enough records to rate Bicoloured Skimmer sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Libellulidae
The closest relatives of the Bicoloured Skimmer that you can see in Litchfield National Park (family Libellulidae, Skimmers) are Painted Grasshawk (about 70%), Pygmy Percher (about 40%) and Chalky Percher (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bicoloured Skimmer is recorded against all the insects logged in Litchfield National Park (8 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.
