In 3 days ~50% in a week ~80%
Austroargiolestes calcaris is a species of Australian damselfly in the family Argiolestidae, commonly known as a powdered flatwing. It is endemic to south-eastern Australia, where it inhabits streams, deep pools and bogs, generally in mountainous areas.
Austroargiolestes calcaris is a medium-sized to large, black and pale yellow damselfly, strongly pruinescent when mature. Like other members of the family Argiolestidae it rests with its wings outspread. Austroargiolestes calcaris appears similar to Austroargiolestes isabellae, which is found in the Sydney Basin.
The genus name Austroargiolestes combines the prefix austro- (from Latin auster, meaning "south wind", hence "southern") with Argiolestes, the name of a related genus. It refers to a southern representative of that group.
The species name calcaris is derived from the Latin calcar ("spur"), referring to the spine on male appendages. List of Odonata species of Australia Wikipedia →

Possible
About 20% of wildlife watchers report a Powdered Flatwing sighting in Kosciuszko National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 25th most-seen of the 105 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November to January
In those months about 30% of wildlife watchers report a Powdered Flatwing in Kosciuszko National Park on a given day, against under 5% in March to October, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Powdered Flatwing 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 Kosciuszko National Park, in our data
Kosciuszko National Park is the only park on Wallace's Line with enough records to rate Powdered Flatwing sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Powdered Flatwing is recorded against all the insects logged in Kosciuszko National Park (22 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.
