General Description

A medium-size (3.0-3.5 cm wingspan) pale buff grey moth. They lack "dagger-marks" and there is no basal dash. The antemedian and the post median lines are doubled, and the area between the two is usually paler than the remainder of the wing. The postmedian line is dragged outward at each vein, giving it a saw-toothed appearance. The orbicular spot is a small open circle, and the reniform is a larger, darker incomplete spot. The forewings appear powdery and the markings are all somewhat blurred. The hindwings are shining white, with a bit of grey dusting toward the outer margin. The antennae are simple. The sexes are similar, with females being slightly darker, especially on the hindwings. The pale color and soft blurry pattern will separate it from the other Alberta dagger moths.
