The Genus Gelechia is a group of moths within the family Gelechiidae. There are several synonyms for this genus, including Gelchia, Gelchia, Pachyptilogaster, and Apatetracma. These synonyms were previously used to describe different subgroups of the Genus Gelechia, but taxonomic revisions have since consolidated them under a single classification. Members of the Genus Gelechia are small, often colorful moths that can be found in a variety of habitats, including forests, fields, and gardens. The larvae of many species of Gelechia moths feed on various types of plants, making them important herbivores in many ecosystems.
