the coleophoridae are a family of small moths, belonging to the huge superfamily gelechioidea. collectively known as case-bearers, casebearing moths or case moths, this family is represented on all continents, but the majority are found in temperate areas of the northern hemisphere. they are most common in the palearctic, and rare in sub-saharan africa, south america, and australia; consequently, they probably originated (like most or all other gelechioidea families) in northern eurasia. they are relatively common in houses, they seek out moist areas to rest and procreate.
