General DescriptionA large (5.8-6.8 cm wingspan) moth with grey-brown or "clay-colored" forewings and bright pink hindwings. Hermia is one of the medium-sized underwing moths. The forewings are a rather light even grey or grey-brown, not powdery grey as in unijuga or meskei. The jagged antemedian line and sinuous postmedian line and the large doubled reniform stand out against the lighter background. The hindwings are a bright pink, crossed by an incomplete black median band and a wider black terminal band and white fringe. There are few dark hairs in the basal part of the hindwings, giving it a very clean, neat look. The similar sized C. meskei has grey powdery-looking forewings on which the lines are less contrasting, and red-orange hindwings. Some specimens of hermia greatly resemble C. luciana, which has a browner, broader forewings and orange hindwings. It can also be difficult to separate hermia from smaller specimens of C. semirelicta, which usually have grey, powdery forewings and a slightly more orange shade of pink on the hindwings.
