Not much is known of this deep-dwelling butterfly, but recent observations indicate that it can form small groups of up to 5 individuals and inhabits steep outer reef drop-offs in rubble areas or among growths of black coral and sea fans. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
