Tetracona amathealis
In 3 days ~10% in a week ~20%
Tetracona amathealis is a species of snout moth in the subfamily Spilomelinae of the family Crambidae. It was described by Francis Walker in 1859 based on material collected at Moreton Bay in Queensland, Australia. It is found in New Guinea and Australia, where it has been recorded in Queensland, northern New South Wales and Western Australia. The species was formerly placed in the genus Agrotera, but in a recent taxonomic revision it was transferred back to the re-instated genus Tetracona, of which it is the type species.
The wingspan is about 20 mm. The caterpillars feed on Eucalyptus tereticornis, a plant of economic interest, which is why T. amathealis is sometimes considered a pest species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Tetracona amathealis sighting in Brisbane on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 474th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February and March
In those months about 10% of wildlife watchers report a Tetracona amathealis in Brisbane on a given day, against under 5% in April to January, the lowest months. Those are among Brisbane's wettest months, with about 150 mm of rain a month against 40 mm in July.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Tetracona amathealis sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Tetracona amathealis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Tetracona amathealis that you can see in Brisbane (family Crambidae, Crambid Snout Moths) are Grass Webworm Moth (about 20%), Hawaiian Beet Webworm Moth (about 10%) and Culladia cuneiferellus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tetracona amathealis is recorded against all the insects logged in Brisbane (20 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.
