Dasypodia selenophora, the southern old lady moth, southern moon moth, or granny moth, is a moth of the family Noctuidae. The species was first described by Achille Guenée in 1852. It is found in the southern half of Australia, as well as Norfolk Island, New Zealand and Macquarie Island.
The adult may be a range of brown shades, with large black and blue eyespots on the centre of the forewings. The body is hairy. The wingspan is about 90 mm. The southern old lady moth is commonly observed during the day in dark areas of homes and other buildings.
The larvae have long brown stripes along the body and short stiff hairs. They feed on Acacia species, including Tan Wattle (Acacia decurrens), Cootamundra Wattle (Acacia baileyana), Golden Wattle (Acacia pycnantha), and Silver Wattle (Acacia dealbata). Wikipedia →

Possible
About 20% of wildlife watchers report a Southern Moon Moth sighting in Perth on a given day, based on 141 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 275 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
October to December
In those months about 30% of wildlife watchers report a Southern Moon Moth in Perth on a given day, against under 5% in February, April–June and August, the lowest months. Those are among Perth's driest months, with about 25 mm of rain a month against 130 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Southern Moon Moth sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 4 cities where we can rate Southern Moon Moth sightings, Perth has the highest daily chance: about 20%. Next come Melbourne (Australia, about 10%) and Sydney (Australia, about 10%).
Same family: Erebidae
The closest relatives of the Southern Moon Moth that you can see in Perth (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Black-And-White Tiger Moth (about 20%), White Cedar Moth (about 10%) and Green Drab (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Moon Moth is recorded against all the insects logged in Perth (141 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.
