The Elachistidae (grass-miner moths) are a family of small moths in the superfamily Gelechioidea. Some authors lump about 3,300 species in eight subfamilies here, but this arrangement almost certainly results in a massively paraphyletic and completely unnatural assemblage, united merely by symplesiomorphies retained from the first gelechioid moths.

The Elachistidae (grass-miner moths) are a family of small moths in the superfamily Gelechioidea. Some authors lump about 3,300 species in eight subfamilies here, but this arrangement almost certainly results in a massively paraphyletic and completely unnatural assemblage, united merely by symplesiomorphies retained from the first gelechioid moths.
In fact, most of these moths appear to be either closer to the Oecophorinae and are hence nowadays usually included in the Oecophoridae (Depressariinae, "Deuterogoniinae", Hypertrophinae, Stenomatinae and perhaps the enigmatic Aeolanthes), or constitute quite basal lineages of gelechioids, neither closely related to Elachista nor to Oecophora, and hence best treated as independent families within the Gelechioidea (Agonoxenidae, Ethmiidae). The genus Coelopoeta is sometimes still placed here, but probably belongs in the Oecophorinae.
