With luck
About 10% of wildlife watchers report a Shining Scoparia sighting in Egmont National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 69th most-seen of the 191 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.
January and March
In those months about 20% of wildlife watchers report a Shining Scoparia in Egmont National Park on a given day, against under 5% in February and April–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.
Among the best
Of the 2 parks where we can rate Shining Scoparia sightings, Egmont National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Arthur's Pass National Park (New Zealand, about 10%).
Same genus: Eudonia
The closest relatives of the Shining Scoparia that you can see in Egmont National Park (genus Eudonia) are Eudonia melanaegis (about 10%), Eudonia feredayi (about 10%) and Mountain Scoparia (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 Egmont National Park (9 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.
