Description of Cosmopterigidae
The Cosmopterigids are members of the Superfamily Gelechioidea. They have a worldwide distribution with 1,650 species in more than 100 genera, richly represented on oceanic islands. They are a diverse group of tiny to small micromoths (wingspan 0.4-2.6 cm) that are small and slender with lancelike or somewhat broad wings, not defined by any uniquely derived characteristic. Larval feeding habits are diverse; most are internal feeders, leaf miners, or bud, stem, bark, or root borers.
