Aethriamanta circumsignata known as the square-spot basker is a species of dragonfly in the family Libellulidae. It is found in Australia, and New Guinea. The species is usually found near still or sluggish waters. In northern Australia, it is found coastal and adjacent inland in an arc from Broome, Western Australia to around Coffs Harbour in New South Wales.
They are a small dragonfly with a wingspan of 40–60 mm, and predominantly red in colour. The wings have less venation than larger dragonflies, and few antenodal cross-veins. Adults may be found at some distance from water. The hindwing has a brown mark at the base which is squarish in shape, leading to its common name. The taxon has been assessed as being of least concern for the IUCN Red List.
The square-spot basker Aethriamanta circumsignata and L-spot basker Aethriamanta nymphaeae are very similar dragonflies and can be difficult to separate. The common name describes dark markings at the base of the hindwing of each species.
The square-spot basker generally has two dark brown flecks. One radiates between the second and third vein (Sc and R) and the other radiates between the fourth and fifth vein (Cu... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Square-Spot Basker is recorded against all the insects logged in Brisbane (98 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.
