Diplopseustis perieresalis
In 3 days ~20% in a week ~50%
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 Egmont National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 153rd most-seen of the 191 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Eastern Black Tabby is recorded against all the insects logged in Egmont National Park (5 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.
