Diplopseustis perieresalis
In 3 days ~10% in a week ~20%
Diplopseustis perieresalis is a species of moth in the family Crambidae. It is widespread in the Oriental region, Australia and New Zealand, but was introduced to the Western Palaearctic realm, where it quickly expanded its range, and where it is now found in Great Britain, the Netherlands, Belgium, Germany, France, Switzerland, Spain, Portugal and the Canary Islands. In the Afrotropics, a single female specimen has been collected in 1904 in Sudan.
The wingspan is about 15 mm. The larvae very likely feed on some part of the New Zealand endemic sedge makura (Carex secta), based on observations in Central Otago. Wikipedia →

Rare
Under 5% of wildlife watchers report an Eastern Black Tabby sighting in Melbourne on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 480th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Eastern Black Tabby in Melbourne on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Eastern Black Tabby sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
3rd of 4
Of the 4 cities where we can rate Eastern Black Tabby sightings, Melbourne ranks 3rd at under 5%. The best odds are in Auckland (New Zealand, about 10%) and Brisbane (Australia, under 5%).
Same family: Crambidae
The closest relatives of the Eastern Black Tabby that you can see in Melbourne (family Crambidae, Crambid Snout Moths) are Scoparia exhibitalis (about 10%), Nacoleia rhoeoalis (about 10%) and Tree Lucerne Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eastern Black Tabby is recorded against all the insects logged in Melbourne (16 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.
