Antennae black, beneath ochreous-whitish. Thorax white, anterior half, a square central spot, and posterior extremity suffused with black. Abdomen whitish-ochreous, slightly irrorated with grey, segmental margins more ochreous towards base. Legs white, thinly sprinkled with black, tibiae and tarsi banded with black. Forewings elongate, triangular, costa hardly arched, apex rounded, hindmargin sinuate, slightly oblique; white, irregularly irrorated with black scales which are ochreous at their base; a triangular blackish spot on costa at base, apex extended to form a smaller spot, but not quite reaching inner margin; inner margin beneath this whitish-ochreous; a broad cloudy white line near first line, more or less confluent with it above; first line broad, cloudy, white, oblique, hardly curved, rather irregular, posteriorly blackish-margined, forming...

With luck
About 10% of wildlife watchers report a Shining Scoparia sighting in Auckland on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 221st 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 40%, if each day is a fresh chance.
December to March
In those months about 10% of wildlife watchers report a Shining Scoparia in Auckland on a given day, against under 5% in April to November, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Shining Scoparia 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 Shining Scoparia sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Eudonia
The closest relatives of the Shining Scoparia 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 Shining Scoparia is recorded against all the insects logged in Auckland (27 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.
