Abstract

Elachista baltica Hering, 1891, previously synonymised with Elachista freyerella (Hübner, 1825) is considered to be a good species. Morphological differences between E. baltica Hering, 1891, E. consortella Stainton, 1851, E. exactella (Herrich—Schäffer, 1855), E. freyerella, and E. stabilella Stainton, 1858 are presented and discussed. E. baltica is redescribed, including morphology ofgenitalia of both sexes, full grown larva and details on biology. The adults of E. baltica have been reared from larvae mining on Festuca rubra ssp. arenaria (Obs) Syme.
