The white-shouldered house moth (Endrosis sarcitrella) is a species of gelechioid moth. It belongs to the subfamily Oecophorinae of the concealer moth family (Oecophoridae), just like the brown house moth (Hofmannophila pseudospretella). Though several presumed congeners of E. sarcitrella were described, its genus Endrosis is currently understood to be monotypic.
This moth is a common species, found by now almost worldwide due to its synanthropic habits. It occurs regularly inside buildings, and being continuously-brooded, can be found at any time of year. It frequents light sources, and can be found in outbuildings where dried food such as grain is kept. It also inhabits birds nests.
The larva is a little grub-like caterpillar and lives on dry plant and animal debris, where it spins itself a small silken hideout. Recorded foodstuffs include dried fruits, cereals (including bran and flour) and other seeds, potatoes, rotting wood, and even insect specimens, wool and old textiles, and guano.
As type species of Endrosis, the white-shouldered house moth was originally included in the genus when it was established (by Jacob Hübner in 1825) as Alucita betulinella, a scientific... Wikipedia →

Possible
About 20% of wildlife watchers report a White-Shouldered House Moth sighting in Rakiura National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 118 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September and November
In those months about 40% of wildlife watchers report a White-Shouldered House Moth in Rakiura National Park on a given day, against under 5% in February–April and June–August, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most White-Shouldered House Moth sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 4 parks where we can rate White-Shouldered House Moth sightings, Rakiura National Park has the highest daily chance: about 20%. Next come Wadden Sea National Park (Germany, about 10%) and Blue Mountains National Park (Australia, about 10%).
Same family: Oecophoridae
The closest relatives of the White-Shouldered House Moth that you can see in Rakiura National Park (family Oecophoridae, Concealer Moths) are Izatha huttoni (about 20%) and Ruddy Streak (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-Shouldered House Moth is recorded against all the insects logged in Rakiura National Park (22 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.
