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).
这只深栖性的蝴蝶知道的不多，但是最近的观察指出它能形成多达 5个个体的小群鱼群而且在碎石区域中或在黑珊瑚与海扇的成长之中居住于陡峭的外围礁石海峭壁。 卵生的.(参考文献 205) 形式在繁殖的时候配对。 (参考文献 205)
