The 'Ear' moths, or Amphipoea species are so alike that it is not usually reliable to distinguish them without referring to their genitalic structure.
Three 'Ear' moths occur in The Netherlands: Amphipoea fucosa, Amphipoea lucens and Amphipoea oculea.
A. fucosa prefers wet and/or humid habitat and is usually seen near the coast or near water.
A. lucens occurs exclusively on moorland and bog areas.
A. oculea prefers sandy soil areas.
