Eudonia steropaea is a species of moth of the family Crambidae. It was named by Edward Meyrick in 1884. Meyrick gave a detailed description of this species in 1885. It is endemic to New Zealand. The wingspan is 13–16 mm. The forewings are pale fuscous, irrorated with darker. There is a small blackish spot at the base of the inner margin and a straight black streak from the base to somewhat before the middle of the disc, almost meeting a triangular blackish blotch. The first line is indicated by an angulated darker posterior margin. The second line is white. The hindwings are grey-whitish, the hindmargin somewhat suffused with darker. Adults have been recorded on wing in January. Wikipedia →

With luck
About 10% of wildlife watchers report a Eudonia steropaea sighting in Auckland on a given day, based on 60 verified sightings from GBIF citizen-science data. It is the 122nd most-seen of the 689 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.
October and November
In those months about 20% of wildlife watchers report a Eudonia steropaea in Auckland on a given day, against under 5% in May–June, August and December, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Eudonia steropaea sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate Eudonia steropaea sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Eudonia
The closest relatives of the Eudonia steropaea that you can see in Auckland (genus Eudonia) are Eudonia philerga (about 20%), Eudonia leptalea (about 10%) and Eudonia bisinualis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eudonia steropaea is recorded against all the insects logged in Auckland (60 verified sightings), 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.
