With luck
About 10% of wildlife watchers report an Aurora Bluetail sighting in Sydney on a given day, based on 70 verified sightings from GBIF citizen-science data. It is the 144th most-seen of the 742 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
September to November
In those months about 10% of wildlife watchers report an Aurora Bluetail in Sydney on a given day, against under 5% in December to August, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Aurora Bluetail sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 cities where we can rate Aurora Bluetail sightings, Sydney ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Perth (Australia, about 10%), Brisbane (Australia, about 10%) and Melbourne (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Aurora Bluetail is recorded against all the insects logged in Sydney (70 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.
