Endrosis sarcitrella, commonly known as the White-shouldered House Moth, is a small moth found in various environments including homes and warehouses. It has a wingspan of 10-23 mm, with distinctive white markings on its shoulders. This species feeds on a variety of organic materials, often considered a pest in stored products.

Endrosis sarcitrella, commonly known as the white-shouldered house moth, is originally native to the Palearctic region. This encompasses parts of Europe, North Africa, and Asia, particularly in temperate climates. However, due to human activity, it has been introduced to many other parts of the world including North America, Australia, and New Zealand.

The white-shouldered house moth is typically found in indoor environments, such as homes, warehouses, and other buildings. It thrives in temperate conditions with access to food sources such as grains, dried fruits, and fabrics. It can also be found in bird nests, where it feeds on feathers, hair, and other organic materials.

Endrosis sarcitrella occupies an ecological niche as a scavenger of organic matter, particularly within human environments. It plays a role in the decomposition process by feeding on a variety of organic materials, including stored food products and natural fibers, which can lead to it being considered a pest in household and storage settings.
