Elachista
grass-miner moths, typical grass miner moths
Elachista is a large genus of very small gelechioid moths, the type genus of the family Elachistidae. These grass-miner moths are characterized by reduced, "feathery" hindwings and typically display one to three light transverse bands on the forewing uppersides. The genus has a near-cosmopolitan distribution, being absent only from very cold regions and some oceanic islands, with highest diversity in the Palearctic. Taxonomic complexity includes numerous undescribed species, cryptic species complexes, and disputed subgeneric classifications.
