Erechthias stilbella is a species of moth in the family Tineidae. It was first described by Edward Doubleday in 1843. This species is endemic to New Zealand and is found in the North and South Islands. This species inhabits native forest and bush and can also be found in domestic gardens. Larvae feed on dead plant debris or tough leaves of plants such as palms. Adults are on the wing from October until March. Adults rest on tree trunks or fences during the day.
This species was first described by Edward Doubleday in 1843 using a specimen collected by A. Sinclair at Auckland and named Argyrotesia stilbella. In 1880 Meyrick placed this species in Erechthias. In 1915 Meryick then went on to place this species in the genus Hectacma. George Hudson discussed and illustrated this species in his 1928 book The butterflies and moths of New Zealand under that name. In 1988 John S. Dugdale synonymised Hectacma with the genus Erechthias and thus this species returned to the name Erechthias stilbella. The type specimen is not at the Natural History Museum, London but Dugdale states a specimen collected by Edward Meyrick and dated 3/14 is topotypic.

Rare
Under 5% of wildlife watchers report an Erechthias stilbella sighting in Auckland on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 370th 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 30%, if each day is a fresh chance.
November to January
In those months about 10% of wildlife watchers report an Erechthias stilbella in Auckland on a given day, against under 5% in February to October, the lowest months.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate Erechthias stilbella sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Erechthias
The closest relatives of the Erechthias stilbella that you can see in Auckland (genus Erechthias) are Erechthias capnitis (about 10%) and Erechthias terminella (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Erechthias stilbella is recorded against all the insects logged in Auckland (12 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.
