Austrolestes io is a medium-sized to large damselfly, the male is light blue and brown. 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 io is named after Io, a figure from Greek mythology. List of Odonata species of Australia Wikipedia →

Rare
Under 5% of wildlife watchers report an Iota Ringtail sighting in Perth on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 188th most-seen of the 275 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and July
In those months about 10% of wildlife watchers report an Iota Ringtail in Perth on a given day, against under 5% in May–June and August–March, the lowest months. Those are among Perth's wettest months, with about 80 mm of rain a month against 10 mm in December.
Only Perth, in our data
Perth is the only city on Wallace's Line with enough records to rate Iota Ringtail sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Austrolestes
The closest relatives of the Iota Ringtail that you can see in Perth (genus Austrolestes, Ringtails) are Blue Ringtail (about 10%) and Slender Ringtail (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Iota Ringtail is recorded against all the insects logged in Perth (8 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.
