Euxoa eruta is a moth of the family Noctuidae.

It is found in Italy, Spain, France, Germany, Denmark, Fennoscandia, Austria, Switzerland, Hungary, Bulgaria, the Czech Republic, Greece, Turkey, Belarus, the Baltic region, Siberia and from central Asia up to the Altai Mountains.

Furthermore, although Fibiger (1997) treated Euxoa montivaga differently it belongs to the E. tritici complex.

Differences among the species are subtle, the most important diagnostic characteristics being genitalic.

In studies of three of these species, E. tritici, E. nigrofusca and E. eruta, no support was found for the presence of several morphologically distinguishable species with quantitative morphometric analyses.
