In 3 days ~20% in a week ~40%
Crypsiphona ocultaria (erroneously as: Phalaena occultaria Guenée, 1857) the red-lined looper moth or red-lined geometer, is a moth of the family Geometridae. The species was first described by Edward Donovan in 1805 and it is found in Australia.
It is one of the most common moths found in Australia. The "red-lined" part of the name refers to the red markings seen on the undersides of the wings. The moth has a wingspan of 4-5 cm. Both sexes of the moth are similar in appearance. When threatened the grub stands still, pretending to be a stick.
As larvae it is a bluish-green with an off-white line on its sides. The larvae feed on eucalypt leaves. Wikipedia →

With luck
About 10% of wildlife watchers report a Red-Lined Looper sighting in Brisbane on a given day, based on 55 verified sightings from GBIF citizen-science data. It is the 234th 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 40%, if each day is a fresh chance.
January–February, April–June, August–September and November
In those months about 10% of wildlife watchers report a Red-Lined Looper in Brisbane on a given day, against under 5% in March, July, October and December, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Red-Lined Looper sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
4th of 4
Of the 4 cities where we can rate Red-Lined Looper sightings, Brisbane ranks 4th at about 10%. The best odds are in Perth (Australia, about 20%), Melbourne (Australia, about 10%) and Sydney (Australia, about 10%).
Same family: Geometridae
The closest relatives of the Red-Lined Looper that you can see in Brisbane (family Geometridae, Geometer Moths) are Apple Looper (about 10%), Comostola laesaria (about 10%) and Cleora repetita (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-Lined Looper is recorded against all the insects logged in Brisbane (55 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.
