Description
The distinguishing feature of this species of Mycalesis is that the ocellus (eye-spot) in space 2 of the hindwing below is moved inwards and out of line with the other ocelli adjacent to it.

Habitat & Habits
The species shares the same habits as the other Mycalesis species and usually lurks in shady, but open areas in the vicinity of grassland. Its host plant is likely to be one of the species of grasses. Mycalesis perseus cepheus has the same feeble flight as the other members of this genus and usually stops with wings folded closed as shown in the photo. Occasionally, an individual may bask with wings opened in bright sunlight. It is relatively common in Singapore, where it is usually found at the fringes of the nature reserves in shady grassy wasteland, and is found in the company of the other Mycalesis species and The Nigger.
