The White-line Dart (''Euxoa nigrofusca'') is a moth of the family Noctuidae. It is found from Europe, to southern Siberia, central Asia to the Pacific Ocean. In North Africa it is known from Morocco and Algeria. ==Description== The wingspan is 28–40 mm. Colouring and pattern are extremely variable and hardly a specimen has an identical colouring and pattern. The colour varies from grey-brown to dark grey. The costa is pale and the pattern often obscure. Pale orbicular and reniform. The males have relatively short combed antannae, the female antennae are thread-like. Note that ''E. nigrofusca'' may not be a good species. The ''Euxoa tritici'' complex consists of five sibling species in Europe: ''Euxoa tritici'' (Linnaeus, 1761), ''Euxoa nigrofusca'' (Esper, 1788), ''Euxoa eruta'' (Hübner, 1817), ''Euxoa diaphora'' Boursin, 1928 and ''Euxoa segnilis'' (Duponchel, 1836). 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. 〔 Marko Mutanen, 2005 Delimitation difficulties in species splits: a morphometric case study on the Euxoa tritici complex (Lepidoptera, Noctuidae) ''Systematic Entomology'' (2005), 30, 632–643 (pdf ) 〕 This moth flies from June to October depending on the location. There is one generation per year. Larvae feed partly subterraneous on roots of ''Poaceae'' and other low plants.
