The blue ringtail (Austrolestes annulosus) is an Australian damselfly. It is found on most of the continent. The blue ringtail was first described by Edmond de Sélys Longchamps in 1862. The abdomen is 3 cm long. It can easily be confused with Austrocoenagrion lyelli or Caliagrion billinghursti, but can be differentiated through dorsal patterns. They are a thin, medium-sized damselfly with varying coloration, which depends on maturity and temperature. However most are a striking blue with minimal black markings. Females are slightly more robust than males, and have a black and white/pale blue coloration.
It is widely distributed in most of Australia, except for the northern and north-eastern parts. It is active through September to April in still water bodies such as riverine pools, lakes and ponds, including temporary pools.
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 annulosus is derived from the Latin annulus ("ring") and the suffix -osus ("abounding... Wikipedia →

With luck
About 10% of wildlife watchers report a Blue Ringtail sighting in Perth on a given day, based on 65 verified sightings from GBIF citizen-science data. It is the 40th most-seen of the 275 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.
November
In that month about 20% of wildlife watchers report a Blue Ringtail in Perth on a given day, against under 5% in March and June, the lowest months. That is one of Perth's driest months, with about 25 mm of rain against 130 mm in July.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Blue 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.
Yes
Of the 2 cities where we can rate Blue Ringtail sightings, Perth has the highest daily chance: about 10%. Next come Melbourne (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Blue Ringtail is recorded against all the insects logged in Perth (65 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.
