Thudaca obliquella is a moth in the family Depressariidae. It was described by Francis Walker in 1864. It is found in Australia, where it has been recorded from New South Wales, Queensland, the Australian Capital Territory, Tasmania and South Australia.
The wingspan is 16–18 mm. Adults are similar to Thudaca mimodora, but the forewings have the first transverse streak without a dark bar above the middle, the second transverse streak is without a dark bar above the lower end and there is a blackish line along the hindmargin. The hindwings are lighter grey, suffused with pale whitish ochreous. Wikipedia →

Rare
Under 5% of wildlife watchers report a Thudaca obliquella sighting in Great Otway National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 369th most-seen of the 418 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January–April and November
In those months about 10% of wildlife watchers report a Thudaca obliquella in Great Otway National Park on a given day, against under 5% in May–October and December, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Thudaca obliquella sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Great Otway National Park, in our data
Great Otway National Park is the only park on Wallace's Line with enough records to rate Thudaca obliquella sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Thudaca obliquella is recorded against all the insects logged in Great Otway National Park (6 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.
