Pseudagrion ignifer is a species of damselfly in the family Coenagrionidae, commonly known as a flame-headed riverdamsel. It is a medium-sized damselfly with an orange face and pruinose sides to its body and the start of its tail.
It is found in eastern Australia, where it inhabits streams. The genus name Pseudagrion is derived from the Greek ψευδής (pseudēs, "false" or "not true"), combined with Agrion, a genus name derived from the Greek ἄγριος (agrios, "wild"). Agrion was the name given in 1775 by Johan Christian Fabricius for all damselflies.
The species name ignifer is Latin for "fire-bearing", referring to the bright rust-coloured markings on the face. List of Odonata species of Australia Wikipedia →

Rare
Under 5% of wildlife watchers report a Flame-Headed Riverdamsel sighting in Brisbane on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 489th most-seen of the 1083 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.
February and March
In those months about 10% of wildlife watchers report a Flame-Headed Riverdamsel in Brisbane on a given day, against under 5% in April to January, the lowest months. Those are among Brisbane's wettest months, with about 150 mm of rain a month against 40 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Flame-Headed Riverdamsel sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Flame-Headed Riverdamsel sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Flame-Headed Riverdamsel is recorded against all the insects logged in Brisbane (24 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.
