With luck
About 10% of wildlife watchers report an Australasian Privet Hawkmoth sighting in Brisbane on a given day, based on 47 verified sightings from GBIF citizen-science data. It is the 267th most-seen of the 1083 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.
January to March
In those months about 10% of wildlife watchers report an Australasian Privet Hawkmoth in Brisbane on a given day, against under 5% in April to December, the lowest months. Those are among Brisbane's wettest months, with about 140 mm of rain a month against 40 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Australasian Privet Hawkmoth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Australasian Privet Hawkmoth is recorded against all the insects logged in Brisbane (47 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.
