In 3 days ~50% in a week ~80%
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 →

Possible
About 20% of wildlife watchers report a Red-Lined Looper sighting in Hattah-Kulkyne National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 61 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April and May
In those months about 40% of wildlife watchers report a Red-Lined Looper in Hattah-Kulkyne National Park on a given day, against under 5% in January–February, June–August and November, 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.
Yes
Of the 8 parks where we can rate Red-Lined Looper sightings, Hattah-Kulkyne National Park has the highest daily chance: about 20%. Next come Great Otway National Park (Australia, about 10%) and Booderee National Park (Australia, about 10%).

GBIF citizen-science records
It is estimated from how often the Red-Lined Looper is recorded against all the insects logged in Hattah-Kulkyne National Park (11 verified sightings from 2019 to 2026), 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.
