| Summary: | 17. Melanchra adjuncta (Morrison) Hitched Arches (Fig. 33, Map 18) Identification: Forewing length 15–19 mm. This is a black moth with white markings. The white markings include the basal line, orbicular spot, prominent reniform spot, and a zig-zag subterminal line. There are two small white spots on the costa above both the orbicular and reniform spots and three short dashes along costa between reniform and apex. Hindwing is white, but heavily suffused with black giving a dark gray appearance. The veins are highlighted with black and a faint postmedial line is present in most specimens. There is a series of shallow crescent-shaped lines between the veins along the outer margin. Flight period: May to June and August, apparently double brooded in the Park. Collected localities: North Carolina: Haywood Co., Cataloochee, Purchase Knob, Purchase Knob at house, Purchase Knob NW of house; Swain Co., Big Cove Road site p.
