Eudonia octophora is a species of moth belonging to the family Crambidae. It was named by Edward Meyrick in 1884. It is endemic to New Zealand and has been observed in both the North and South Islands as well as the Chatham Islands. This species is known to inhabit wetlands and its larval plant host are species within the genus Juncus. Adults are commonly on the wing from October until May and are attracted to light.
This species was first described by Edward Meyrick in 1884 and originally named Xeroscopa octophora. He described this species more fully in 1885. He used species collected at various locations in the lower half of the South Island. George Hudson discussed and illustrated this species under the name Scoparia octophora, though his illustration was regarded by John S. Dugdale as dubious. In 1988 Dugdale placed this species in the genus Eudonia. The male lectotype specimen, collected at Castle Hill, Canterbury, is held at the Natural History Museum, London.
Meyrick described this species as follows: Male, female. — 22-24 mm. Head and thorax brownish-ochreous, shoulders irrorated with dark fuscous. Palpi 3+1⁄2, dark fuscous, mixed with white... Wikipedia →

Possible
About 20% of wildlife watchers report a Eudonia octophora sighting in Rakiura National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 118 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.
November
In that month about 40% of wildlife watchers report a Eudonia octophora in Rakiura National Park on a given day, against under 5% in March and July–September, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Eudonia octophora sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 parks where we can rate Eudonia octophora sightings, Rakiura National Park has the highest daily chance: about 20%. Next come Fiordland National Park (New Zealand, about 10%).
Same genus: Eudonia
The closest relatives of the Eudonia octophora that you can see in Rakiura National Park (genus Eudonia) are Eudonia philerga (about 20%), Greater Orange-Spot Scoparia (about 10%) and Eudonia legnota (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eudonia octophora is recorded against all the insects logged in Rakiura National Park (22 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.
