With luck
About 10% of wildlife watchers report an Austral Ellipsidion sighting in Brisbane on a given day, based on 37 verified sightings from GBIF citizen-science data. It is the 325th 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 30%, if each day is a fresh chance.
February, May–June and September–December
In those months about 10% of wildlife watchers report an Austral Ellipsidion in Brisbane on a given day, against under 5% in January, March–April and July–August, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Austral Ellipsidion sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Austral Ellipsidion sightings, Brisbane ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Melbourne (Australia, about 10%) and Sydney (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Austral Ellipsidion is recorded against all the insects logged in Brisbane (37 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.
