Female
Forewing length (mm): 85-125. Wingspan (mm):140-210.
Forewing, upperside brown to black with complete series of submarginal spots, median spots in spaces 1c, 2 and 3 (in 2 biggest), no spot in cell; underside similar.

Subspecies and variation

Similar species

Male and female are rather similar to O. chimaera and O. tithonus. Male of O. rothschildi recognizable by the less well defined green patches on the forewing and the higher number of median spots on the hindwing. Female of O. rothschildi lacks cell spot on forewing, present in O. chimaera and O. tithonus; in latter species, median spots on hindwing are further to the wing margin than in O. rothschildi.
