Common NameVariable Dart; Dingy DartIdentificationA medium-size, dark dull brown Euxoa. Infausta belongs to a group of 8 species in the infausta group; the good news is that only one other member of the group (E. satiens) is known from AB. The aridland form found in southern AB can be recognized by the even buff-brown or pale grey-brown FW. In forested habitats including the foothills, it is a darker brown with a mottled FW. The HW is almost as dark. See Lafontaine (197) for a key to the infausta group.
