With luck
About 10% of wildlife watchers report an Austral Ellipsidion sighting in Melbourne on a given day, based on 451 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 875 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
October to December
In those months about 20% of wildlife watchers report an Austral Ellipsidion in Melbourne on a given day, against under 5% in May and July, 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.
Yes
Of the 4 cities where we can rate Austral Ellipsidion sightings, Melbourne has the highest daily chance: about 10%. Next come Sydney (Australia, about 10%) and Brisbane (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Austral Ellipsidion is recorded against all the insects logged in Melbourne (451 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.
