Callerebia polyphemus is a butterfly found in the east Palearctic (western China and Japan) that belongs to the browns family (Nymphalidae).
Callerebia polyphemus Oberthür (34 f) is by far the largest form of the whole genus, being easily recognized by the size alone; the upperside of the forewing bears frequently accessory ocelli.
[Pradesh, India Callerebia hybrida Butler, 1880] (= annada Marsh and de Nicev.
(35 a), which is only half the size, has an oval apical ocellus on the forewing and 2 ocelli in the anal area of the underside of the hindwing; comes nearest to the name-typical annada.
The border of the ocellus of the forewing is continued towards the hindmargin of the wing as an orange-brown band, within which there are 2 ocelli; the hindwing, too, bears 2 submarginal small ocelli on the upperside.
