Paranotoreas brephosata is a species of moth in the family Geometridae. This species is endemic to New Zealand. This species was first described by Francis Walker in 1862 and given the name Fidonia brephosata. George Hudson discussed and illustrated this species in his 1898 book New Zealand Moths and Butterflies (Macro-lepidoptera) and his 1928 book The Butterflies and Moths of New Zealand under the name Notoreas brephos. In 1986 Robin C. Craw proposed placing this species within the genus Paranotoreas. The lectotype specimen is held at the Natural History Museum, London.
Hudson described the species as follows: The expansion of the wings is about 1 inch. The fore-wings are dark grey; there is a wavy black line near the base, two similar lines enclosing a very broad central area, with a black dot a little above the middle; beyond this there is a more or less distinct wavy band of pale grey or brown; there are several obscure wavy blackish lines near the termen. The hind-wings are bright orange, dotted with grey near the base and dorsum, with from two to four more or less distinct wavy black transverse lines, generally rather narrow; the termen is moderately...

Possible
About 20% of wildlife watchers report an Orange Underwing sighting in Arthur's Pass National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 60 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report an Orange Underwing in Arthur's Pass National Park on a given day, against under 5% in April to October, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Orange Underwing sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Orange Underwing sightings, Arthur's Pass National Park has the highest daily chance: about 20%. Next come Egmont National Park (New Zealand, about 10%) and Fiordland National Park (New Zealand, about 10%).
GBIF citizen-science records
It is estimated from how often the Orange Underwing is recorded against all the insects logged in Arthur's Pass National Park (16 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.
