In 3 days ~20% in a week ~50%
Pseudocoremia rudisata is a species of moth in the family Geometridae. This species was first described by Francis Walker in 1862. It is endemic to New Zealand and is found in the North, South and Stewart Islands. This species inhabits native forest and scrubland. The larval hosts of this moth include species in the genus Olearia and Brachyglottis repanda. Adults are on the wing throughout the year but are most commonly observed from October until January. Larvae and adults are nocturnal with adults being attracted to light.
This species was first described by Francis Walker in 1862 and originally named Cidaria rudisata. Edward Meyrick described this species in 1891 under the name Selidosema rudiata, an unjustified emendation. George Hudson, following Meyrick, used this same name when he discussed and illustrated this species in 1898 and again in 1928. In 1988 John S. Dugdale placed this species in the genus Pseudocoremia.

With luck
About 10% of wildlife watchers report a Pseudocoremia rudisata sighting in Fiordland National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 96th most-seen of the 201 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.
March and November–January
In those months about 10% of wildlife watchers report a Pseudocoremia rudisata in Fiordland National Park on a given day, against under 5% in February and April–October, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Pseudocoremia rudisata sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Fiordland National Park, in our data
Fiordland National Park is the only park on Wallace's Line with enough records to rate Pseudocoremia rudisata sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Pseudocoremia
The closest relatives of the Pseudocoremia rudisata that you can see in Fiordland National Park (genus Pseudocoremia) are Brown Forest Flash (about 20%), Common Forest Looper (about 20%) and Pseudocoremia terrena (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pseudocoremia rudisata is recorded against all the insects logged in Fiordland National Park (12 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.
