Austrocidaria bipartita is a species of moth of the family Geometridae. It endemic to New Zealand. It was first described by Louis Beethoven Prout in 1958. This species is found throughout New Zealand and adults are on the wing all year round. Adults are nocturnal and are attracted to light. The larval host plants of this moth are species in the genus Coprosma.
This species was first described by Louis Beethoven Prout in 1958 as an aberration of the species Horisme anguligera. John S. Dugdale raised this moth to species level in 1988 on the basis that the colour pattern as well as the male genitalia of this species was distinctive. The male holotype, collected by W. George Howes in Wellington, is held at the Natural History Museum, London.
The larvae are grey in colour and have two raised areas on its abdominal segments. Prout first described the adult of this species as follows: Fore wing : anterior of a line from the apex to two-sevenths of the inner margin the wing is light buff, lightly irrorate with fuscous along the costa; posterior of it the wing is drab irrorate with fuscous, the light buff, postmedial fascia being marked only between veins...

With luck
About 10% of wildlife watchers report an Austrocidaria bipartita sighting in Egmont National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 153rd most-seen of the 191 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.
September and November–December
In those months about 20% of wildlife watchers report an Austrocidaria bipartita in Egmont National Park on a given day, against under 5% in February–August and October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Austrocidaria bipartita sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Egmont National Park, in our data
Egmont National Park is the only park on Wallace's Line with enough records to rate Austrocidaria bipartita sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Geometridae
The closest relatives of the Austrocidaria bipartita that you can see in Egmont National Park (family Geometridae, Geometer Moths) are Forest Semilooper (about 20%), Oblique-Waved Fern Looper (about 20%) and Common Forest Looper (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Austrocidaria bipartita is recorded against all the insects logged in Egmont National Park (5 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.
