White-Shouldered House Moth

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.
