Chrysorthenches virgata is a species of moth in the family Plutellidae. It was first described by Alfred Philpott in 1920. It is endemic to New Zealand and has been found in the North, South and Chatham Islands at altitudes ranging from sea-level up to approximately 1000 m. This species inhabits areas where its larval host plants, Libocedrus bidwillii and Cupressus macrocarpa are common. The larvae feed on the leaves of their hosts from under a silk shelter and pupate in a cocoon of thick silk covered in frass. Adult moths are on the wing from September to February as well as in April and June.
This species was first described by Alfred Philpott in 1920 and named Orthenches virgata. George Hudson discussed and illustrated this species in his 1928 book The butterflies and moths of New Zealand and again discussed the species in his 1939 book A Supplement to the butterflies and moths of New Zealand. In 1996 John S. Dugdale placed this species in the genus Chrysorthenches. The female lectotype, collected in Auckland by Alfred Jefferis Turner, is held at the New Zealand Arthropod Collection.

Rare
Under 5% of wildlife watchers report a Chrysorthenches virgata sighting in Auckland on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 618th most-seen of the 689 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chrysorthenches virgata in Auckland on a given day, so our monthly data shows no clear season.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate Chrysorthenches virgata sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Chrysorthenches virgata is recorded against all the insects logged in Auckland (5 verified sightings), 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.
