Common NameHermia Underwing SeasonalityAdults are on the wing in August and early September. IdentificationA 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.

Life History
Adults are nocturnal and come to light, but are much more common at sugar baits. They fly in late summer and early fall and lay the eggs, which overwinter. The larvae are solitary defoliators. There is a single brood…
