In 3 days ~10% in a week ~20%
Austroagrion exclamationis is a species of damselfly in the family Coenagrionidae, commonly known as a northern billabongfly. It is a small damselfly; the male is blue and black. It has been recorded from New Guinea and northern Australia,
where it inhabits streams and still water. The genus name Austroagrion combines the prefix austro- (from Latin auster, meaning "south wind", hence "southern") with Agrion, a genus name derived from Greek ἄγριος (agrios, "wild"). Austroagrion thus refers to a southern representative of that group.
The species name exclamationis is derived from the Latin exclamatio ("exclamation"), referring to the marking on segment 3 of its abdomen. List of Odonata species of Australia Wikipedia →

Rare
Under 5% of wildlife watchers report a Northern Billabongfly sighting in Brisbane on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 981st 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.
April
In that month about 10% of wildlife watchers report a Northern Billabongfly in Brisbane on a given day, against under 5% in May to March, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Northern Billabongfly 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 Northern Billabongfly sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Northern Billabongfly is recorded against all the insects logged in Brisbane (17 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.
