General DescriptionA medium-sized (4.0-4.8 cm wingspan) narrow-winged moth with blue-grey forewings and a prominent pale orbicular spot. There is a long thin basal dash and dark contrasting veins; normal lines mostly obsolete and the subterminal line a series of small blackish wedges between the veins. The orbicular is erect, oblong and pale, and the reniform is high and narrow, slightly concave on the outer side, and pale ringed with some dark filling, especially at the lower end. The hindwings are pale brown-grey. The abdomen lacks tufts. The male genitalia lack a recognizable corona, cucullus and digitus. The sexes are similar, but females are darker. Spring specimens are much paler (faded) than freshly emerged fall ones. The similar L. fagina is smaller, has a contrasting pale frosted-looking costa, and lacks the normal spots, darkened veins and other markings of georgii. Cucullia intermedia is also similar but has pointed forewings (squared in Lithophane).
