Eucosma

Eucosma is a very large genus of moths belonging to the family Tortricidae. The genus has a Holarctic and Indomalayan distribution (Some Afrotropical species originally described in this genus have since been reassigned to other genera ). Even in well-studied Europe and North America, new species are still regularly discovered (Nomina Insecta Nearctica lists 150 Nearctic species and Fauna Europaea lists 53 European species).
