Diplopseustis perieresalis
In 3 days ~20% in a week ~40%
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 →

With luck
About 10% of wildlife watchers report an Eastern Black Tabby sighting in Auckland on a given day, based on 45 verified sightings from GBIF citizen-science data. It is the 150th most-seen of the 689 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
September and November–July
In those months about 10% of wildlife watchers report an Eastern Black Tabby in Auckland on a given day, against under 5% in August and October, the lowest months.
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.
Yes
Of the 4 cities where we can rate Eastern Black Tabby sightings, Auckland has the highest daily chance: about 10%. Next come Brisbane (Australia, under 5%) and Melbourne (Australia, under 5%).

GBIF citizen-science records
It is estimated from how often the Eastern Black Tabby is recorded against all the insects logged in Auckland (45 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.
