Pasiphila sandycias is a moth in the family Geometridae. It was first described by Edward Meyrick in 1905. This species is endemic to New Zealand and is found in the southern half of the North Island, throughout the South Island and on Stewart Island. It inhabits native scrub populated with its larval host plants, Coprosma areolata and Coprosma rotundifolia. The larvae feed on the blossoms of its hosts and this life stage is synchronised with the flowering of those plants. The larvae are well camouflaged as they appear similar to a roughened Comprosma twig. The pupa is enclosed in a cocoon made of silk and refuse and can be found amongst shoots of its host plants. Adult moths have been observed on the wing from August to February. They are nocturnal, attracted to light and have been shown to pollinate Leptospermum scoparium and Olearia virgata.
George Hudson in his 1898 book New Zealand moths and butterflies (Macro-lepidoptera) illustrated and discussed this species mistaking it for what is now known as Pasiphila plinthina. Edward Meyrick, recognising that the species was new, first described it in 1905 and originally named it Chloroclystis sandycias. In 1928 Hudson... Wikipedia →

With luck
About 10% of wildlife watchers report a Pasiphila sandycias sighting in Fiordland National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 171st 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 40%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Pasiphila sandycias in Fiordland National Park on a given day, against under 5% in February to November, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Pasiphila sandycias sightings with a recorded time, and about 9 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 Pasiphila sandycias sightings, Fiordland National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Rakiura National Park (New Zealand, about 10%).
Same genus: Pasiphila

GBIF citizen-science records
It is estimated from how often the Pasiphila sandycias is recorded against all the insects logged in Fiordland National Park (8 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.
