Austrocidaria umbrosa is a species of moth of the family Geometridae. It endemic to New Zealand and has been observed in the South Island in Fiordland. Adults have been recorded as being on the wing in December, January and March. They are nocturnal and have been collected on and around Dracophyllum longifolium.
This species was first described in 1917 by Alfred Philpott using specimens collected at Mount Cleughearn in Fiordland at around 3,250 ft and named Xanthorhoe umbrosa. In 1928 George Hudson discussed and illustrated this species under that name in his book The butterflies and moths of New Zealand. In 1988 John S. Dugdale placed this species in the genus Austrocidaria. The male holotype specimen is held at the New Zealand Arthropod Collection.
Philpott described this species as follows: ♂♀. 33-40 mm. Head, palpi, and thorax dull-greenish, tinged with ochreous and sprinkled with blackish. Antennae moderately bipectinated, brownish-ochreous. Abdomen ochreous-grey with paired black dorsal dots on each segment. Forewings triangular, costa almost straight, termen waved, bowed, oblique; dull green, ochreous-tinged; veins interruptedly outlined in... Wikipedia →

With luck
About 10% of wildlife watchers report an Austrocidaria umbrosa sighting in Fiordland National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 96th most-seen of the 201 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.
January
In that month about 20% of wildlife watchers report an Austrocidaria umbrosa in Fiordland 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 Austrocidaria umbrosa 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 Fiordland National Park, in our data
Fiordland National Park is the only park on Wallace's Line with enough records to rate Austrocidaria umbrosa sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Austrocidaria
The closest relatives of the Austrocidaria umbrosa that you can see in Fiordland National Park (genus Austrocidaria) are Green Coprosma Carpet (about 10%), Dark Coprosma Carpet (about 10%) and Austrocidaria cedrinodes (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Austrocidaria umbrosa is recorded against all the insects logged in Fiordland National Park (10 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.
