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).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Form pairs during breeding (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).

Estimates based on models

Preferred temperature (Ref. 123201): 24.4 - 26.9, mean 25.8 °C (based on 18 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.01133 - 0.04632), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.37 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
