In 3 days ~10% in a week ~20%
Idaea inquinata, the rusty wave, is a moth of the family Geometridae. It is found in Europe. The species has a wingspan of 16–19 mm. The length of the forewings is 8–10 mm. The adults fly at night from June to July [1] in Britain. The species is a rare and introduced species in England and is believed to have come to this country with imported dried flowers and herbs. The foodplant is believed to be dried or withered plants because of this.
^The flight season refers to the British Isles. This may vary in other parts of the range. Wikipedia →

Rare
Under 5% of wildlife watchers report a Rusty Wave sighting in Melbourne on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 389th most-seen of the 875 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.
November
In that month about 10% of wildlife watchers report a Rusty Wave in Melbourne on a given day, against under 5% in December to October, the lowest months.
Among the best
Of the 3 cities where we can rate Rusty Wave sightings, Melbourne ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Kyiv (Ukraine, under 5%).
GBIF citizen-science records
It is estimated from how often the Rusty Wave is recorded against all the insects logged in Melbourne (24 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.
