Austrolestes analis
In 3 days ~10% in a week ~20%
The slender ringtail (Austrolestes analis) is an Australian damselfly in the family Lestidae. It is characterized by having a relatively slender body compared to other species in the genus. The slender ringtail was first described by Jules Pierre Rambur in 1862.
The abdomen is 3-3.2 cm long. Mature males are often pale blue and black although the strength of the blue may vary. Distinguished from other Austrolestes by the pattern on the upper thorax, most closely resembling that of Austrolestes aridus.
It is found in south-western Western Australia, south-eastern South Australia, Victoria, New South Wales and Tasmania. It is active through Spring to Autumn near lakes, slow flowing rivers and nearby vegetation. The genus name Austrolestes combines the prefix austro- (from Latin auster, meaning “south wind”, hence “southern”) with Lestes, a genus name derived from Greek λῃστής (lēstēs, “robber”).
The species name analis is Latin for "of the anus", likely referring to features of the anal region. Wikipedia →

Rare
Under 5% of wildlife watchers report a Slender Ringtail sighting in Sydney on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 492nd most-seen of the 742 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Slender Ringtail in Sydney on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Slender Ringtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Slender Ringtail sightings, Sydney ranks 3rd at under 5%. The best odds are in Melbourne (Australia, about 10%) and Perth (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Slender Ringtail is recorded against all the insects logged in Sydney (9 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.
