The Gelechiidae are a family of moths commonly referred to as twirler moths or gelechiid moths. They are the namesake family of the huge and little-studied superfamily Gelechioidea, and the family's taxonomy has been subject to considerable dispute. These are generally very small moths with narrow, fringed wings. The larvae of most species feed internally on various parts of their host plants, sometimes causing galls. Douglas-fir (Pseudotsuga) is a host plant common to many species of the family, particularly of the genus Chionodes, which as a result is more diverse in North America than usual for Gelechioidea.
Acanthophila is a moth genus. It is here placed in subfamily Dichomeridinae of family Gelechiidae, although it is sometimes treated as junior synonym of Dichomeris.
Chrysoesthia is a genus of moths in the family Gelechiidae.
Deltophora is a genus of moths in the family Gelechiidae. The genus was originally described from South Africa and based on a taxonomic revision contains about 20 species on all continents except Antarctica. Host plants of larvae and adults are only known for two Chinese species of Deltophora. These two species feed on two species of Phyllanthus (Phyllanthaceae), which are their exclusive hosts for both the larval stage and as a nectar-source for the adults. Molecular data support the placement of Deltophora in the Gelechiidae.
