Unidentified small moth or moth case

The object appears attached to an indoor wall, where small household moths or their portable cases may occur; species identification requires a clearer, closer image.

Case-bearing larvae commonly consume lint, hair, feathers, wool, and other keratin-containing debris; adult moths generally do not feed.

Larvae hide in silk or debris cases and crawl over walls or ceilings before pupating; adults are typically nocturnal and attracted to light.

Usually harmless to people, but larvae can damage wool, fur, feathers, carpets, and stored textiles. They also help decompose organic debris.
