General DescriptionEuxoa citricolor belongs to the detersa group, subgenus Euxoa. They are medium-size moths (3.4-3.7 cm wingspan) with pale dull yellow forewings with few markings other than a light dusting of darker scales in some specimens. Forewing markings are greatly reduced, usually confined to a small spot of grey cells at the orbicular, a larger elongated patch marking the reniform, and a terminal band of the same color. In some specimens the antemedian and postmedian lines are thin and scalloped, with a series of dark marks where the lines meet the costa. The hindwings are shining white; females in particular may have some darker scaling along the outer veins and outer margin and a faint median line. The only similar Alberta Euxoa is Euxoa tronella, which is cream or pale buff, not yellow.
