The red and blue damsel, (Xanthagrion erythroneurum) is a damselfly in the family Coenagrionidae. It is the only member of the monotypic genus Xanthagrion. A red and blue damsel has a bright red face and thorax. Its abdomen is pale in colour and 2.2-2.4 cm long. Females and males are similar in colour.
The red and blue damsel is widespread across all Australian states, as well as Fiji, New Caledonia, and other islands in the Pacific. It is found in north and eastern Tasmania. It is typically found near dams, marshes and slow watercourses.
The genus name Xanthagrion is derived from the Greek ξανθός (xanthos, "yellow") and Agrion, a genus name derived from the Greek ἄγριος (agrios, "wild"). Agrion was the name applied by Johan Christian Fabricius in 1775 to all damselflies.
The species name erythroneurum is derived from the Greek ἐρυθρός (erythros, "red") and νεῦρον (neuron, "nerve" or "sinew"), referring to the colour of the major wing veins. Wikipedia →

With luck
About 10% of wildlife watchers report a Red And Blue Damsel sighting in Great Otway National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 178th most-seen of the 418 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Red And Blue Damsel in Great Otway National Park on a given day, against under 5% in March to September, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Red And Blue Damsel sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 parks where we can rate Red And Blue Damsel sightings, Great Otway National Park ranks 4th at about 10%. The best odds are in Hattah-Kulkyne National Park (Australia, about 30%), Grampians National Park (Australia, about 10%) and Kosciuszko National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Red And Blue Damsel is recorded against all the insects logged in Great Otway National Park (15 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.
