About Erebus hieroglyphica (Drury, 1773)
This species has a wingspan of approximately 88 millimeters, and adult individuals display strong sexual dimorphism. Recorded adult feeding behavior includes consuming the juices of tropical fruits. For males, vein 3 of the hindwing extends to the functional apex of the wing. The costal fold is underdeveloped, and a small gland-containing patch is present. Veins 4 through 8 of the male hindwing are moderately developed within the aborted costal area. The male body is a deep rich blackish brown. Beyond the end of the forewing cell, males have a whorl-shaped, bilobed black mark that expands toward the wing’s head edge, and this mark is outlined in blue. An oblique yellow bar runs from the costa near the apex of the forewing, and only a small number of individuals have this bar reaching the outer margin. Females have a brown body marked with black striae. The female forewing features a white oblique bar. Both sexes have faint traces of a postmedial band made up of whitish marks, and a white spot is present on the forewing above vein 3.
