Household Casebearer Moth
Phereoeca uterella
household casebearer moth (Phereoeca uterella) is a species of tineoid moth in the family Tineidae, the fungus moths.

The larva builds a portable, flattened, oval-shaped case from silk and materials like fabric bits or debris, which camouflages it as it feeds.
As the larva grows, it enlarges its case, carrying it around.
Household casebearers are potential household pests because their larvae feed on keratin-rich materials like wool, fur, feathers, and upholstery.
Pupation occurs inside the case, and the empty pupal casing can be seen sticking out after the adult moth emerges.
