Chrysorthenches drosochalca is a species of moth in the family Plutellidae first described by Edward Meyrick in 1905. It is endemic to New Zealand and has been found in the North and South Islands. The larvae are leaf miners of Prumnopitys ferruginea. Adults are on the wing from January to March.
This species was first described by Edward Meyrick in 1905 using specimens collected at Otira Gorge and Wellington and named Orthenches drosochalca. George Hudson discussed and illustrated this species in his 1928 book The butterflies and moths of New Zealand. In 1996 J. S. Dugdale placed this species in the genus Chrysorthenches. The male lectotype, collected by George Hudson in Wellington, is held at the Natural History Museum, London.
Hudson described the larva and pupa of this species as follows: The larva... is about 1⁄4 inch in length, cylindrical tapering at each end with the segmental divisions deeply excised, uniform dark green and shining. The pupa is enclosed in a small oval cocoon fastened to a fern frond.

Rare
Under 5% of wildlife watchers report a Chrysorthenches drosochalca sighting in Auckland on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 574th 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.
October and November
In those months about 10% of wildlife watchers report a Chrysorthenches drosochalca in Auckland on a given day, against under 5% in December to September, the lowest months.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate Chrysorthenches drosochalca 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 drosochalca is recorded against all the insects logged in Auckland (6 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.
