Esperia is a genus of the concealer moth family (Oecophoridae). Among these, it belongs to subfamily Oecophorinae. Most authors include Dasycera here, though approaches that generally follow a "splitting" approach sometimes do not.FE (2009a,b), and see references in Savela (2003)

The type species of Esperia (originally described as Tinea orbonella, now E. sulphurella) has some differences versus the type species of Dasycera (originally described as T. aemulella, now E. oliviella), but these are slight and at present it is not determined whether they justify the maintenance of two small genera versus a more comprehensive genus containing two subgenera.Pitkin & Jenkins (2004a,b), FE (2009a,b), and see references in Savela (2003)

Selected species Species of Esperia (including Dasycera) include: Esperia imitatrix (Zeller, 1847) Esperia krueperella (Staudinger, 1871) Esperia oliviella Esperia sulphurella
