Poecilasthena subpurpureata
In 3 days ~30% in a week ~60%
Poecilasthena subpurpureata is a species of moth of the family Geometridae. It was first described by Francis Walker in 1863 and it is endemic to New Zealand. A synomic species, Astheniodes polycymaria (the two species have almost identical male genitalia), has a holotype that was recorded by George Hampson as being from India, which, as Dayong Xue and Malcolm J. Scoble point out in their paper, would be a very strange distribution pattern. Louis Beethoven Prout reasonably calls this an error in his 1926 paper. Wikipedia →

With luck
About 10% of wildlife watchers report a Poecilasthena subpurpureata sighting in Rakiura National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 60th most-seen of the 118 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.
June and October
In those months about 30% of wildlife watchers report a Poecilasthena subpurpureata in Rakiura National Park on a given day, against under 5% in April–May, July–September and December, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Poecilasthena subpurpureata 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.
Only Rakiura National Park, in our data
Rakiura National Park is the only park on Wallace's Line with enough records to rate Poecilasthena subpurpureata sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Poecilasthena
The closest relatives of the Poecilasthena subpurpureata that you can see in Rakiura National Park (genus Poecilasthena) are Kanuka Looper (about 10%) and Native Cranberry Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Poecilasthena subpurpureata is recorded against all the insects logged in Rakiura National Park (12 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.
