Globia algae

Globia algae, the rush wainscot, is a moth of the family Noctuidae. The species was first described by Eugenius Johann Christoph Esper in 1789. It is found in central and southern Europe (and very sporadically in north-western Europe), Turkey, Armenia, northern Caucasus, south-west Siberia.

The genus Capsula was renamed Globia because of a naming conflict with a mollusk.
