Eudonia trivirgatus is a moth in the family Crambidae. It was first described by Cajetan Felder, Rudolf Felder and Alois Friedrich Rogenhofer in 1875 as Crambus trivirgatus. It is endemic to New Zealand. The wingspan is 16–23 mm. The forewings are whitish ochreous, the veins lined with white. There is a blackish-fuscous median streak from the base to the apex, interrupted by a narrow bar before the middle. There is also a blackish-fuscous longitudinal wedge-shaped mark above the anal angle and usually a hindmarginal row of cloudy blackish dots. The hindwings are grey whitish in males and whitish grey in females. Adults have been recorded on wing in December, February and March. Wikipedia →

With luck
About 10% of wildlife watchers report a Mountain Scoparia sighting in Fiordland National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 27th most-seen of the 201 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report a Mountain Scoparia in Fiordland National Park on a given day, against under 5% in February to November, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Mountain Scoparia sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 2 parks where we can rate Mountain Scoparia sightings, Fiordland National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Egmont National Park (New Zealand, about 10%).
Same genus: Eudonia
The closest relatives of the Mountain Scoparia that you can see in Fiordland National Park (genus Eudonia) are Greater Orange-Spot Scoparia (about 10%), Bold Scoparia (about 10%) and Eudonia feredayi (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mountain Scoparia is recorded against all the insects logged in Fiordland National Park (28 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.
