Thudaca circumdatella is a moth in the family Depressariidae. It was described by Francis Walker in 1865. It is found in Australia, where it has been recorded from New South Wales. The wingspan is 15–16 mm. The forewings are snow white with a suffused brownish-ochreous streak along the basal half of the costa, attenuated and very indistinct posteriorly. There is a straight brownish-orange subdorsal streak from the base to the anal angle, the upper edge with short triangular projection near the extremity. The hindwings are ochreous-grey whitish.

Rare
Under 5% of wildlife watchers report a Thudaca circumdatella sighting in Sydney on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 621st most-seen of the 742 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Thudaca circumdatella in Sydney on a given day, so our monthly data shows no clear season.
Only Sydney, in our data
Sydney is the only city on Wallace's Line with enough records to rate Thudaca circumdatella sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Lepidoptera
The closest relatives of the Thudaca circumdatella that you can see in Sydney (order Lepidoptera, Butterflies and Moths) are Bogong Moth (about 20%), Australian Common Crow (about 20%) and Small White (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Thudaca circumdatella is recorded against all the insects logged in Sydney (9 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.
