About Erebus macrops (Linnaeus, 1768)
This species, Erebus macrops, has a wingspan ranging from approximately 134 to 160 mm. In males, the costal half of the hindwing is modified to fold over onto the upper surface, and contains a large glandular patch of flocculent, woolly hair. Vein 4 runs to the functional apex of the modified wing, while vein 5 originates from the center of the discocellulars. Vein 6 extends to the fold, and veins 7 and 8 are very small, reaching close to the base of the costa. The moth's body and wings are fuscous brown, with a faint purplish tint. Forewings feature short sub-basal black lines, as well as waved antemedial and medial black lines. A very large fulvous ocellus is located beyond the end of the cell; this ocellus has a black outline, a black comma-shaped pupil, and blue streaks and specks across the pupil. Two irregularly waved postmedial lines curve outward around the ocellus and bend inward below it; the outer postmedial line expands into a patch at the costa. There are two sinuous series of black submarginal spots; the inner series is indistinct and no longer visible toward the costa. Hindwings have a medial black line that curves outward around the cell. A postmedial series of lunule spots is present, with two sinuous series of spots located beyond it; the inner of these two series is the least distinct. On the ventral side, each wing has an irregular postmedial series of white spots and a regular submarginal series of lunules.
