Family Oecophoridae (Concealer moths)

Oecophoridae is a family of small moths in the super family Gelechioidea.

Many concealer moths feed on dead plant material and are nutrient recyclers, which can make them pest. An example would be Endrosis sarcitrella, which is a widely distributed moth whose caterpillars infest stored grain, and Hofmannophila pseudospretella, which feeds on textiles and carpets as well as stored foodstuffs.

Concealer moths have also been put to useful service. Agonopterix ulicetella a native of Europe, has been introduced to Nww Zealand and Hawaii in an attempt to control Ulex europaeus, and Agonopterix alstroemeriana has been used against Conium maculatum in the United States.
